Changes between versions 0.4b41 and 0.4b42 (released June 18, 2009)
===================================================================
1. Fix printout of the 'Connection to' message in dump/restore.
Thanks to Dale Wiles <dwiles@users.sourceforge.net> for the
bug report and its fix.
2. Fix dump -w/-W output for filesystems having the last backup
level equal to 0. Thanks to Pascal Bouchareine
<kalou@users.sourceforge.net> for reporting the bug.
3. Enable restore to handle restoring onto a different SELinux
policy from the dump. Thanks to Tony Nelson
<tony_nelson@users.sourceforge.net> for the patch.
(see http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=189845
for details)
4. Fix EA set failures when restoring immutable files. Thanks
to Andrew Kroeger for the patch.
5. Fix "mode file too large" errors when restoring huge backups.
Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
report.
6. Add the ability to link against libtinfo library if present,
instead of libtermcap or libncurses libraries. Thanks to
Adam Tkac <atkac@redhat.com> for the patch.
7. When comparing a backup, do not consider to be an error the fact
that we encounter files created while dump was in progress.
Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
report.
8. Force '-a' to be the default value when running 'restore -C'.
Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
report.
9. Many improvements to the 'cron_dump_to_disk' example.
Thanks to Aaron S. Hawley <ashawley@users.sourceforge.net> for
the patch.
10. Fix the QFA generation when extended attributes are backuped
along with the inodes. Prior to this fix, the entries for
some inodes may get corrupted (duplicated entries or incorrect
ones), making the QFA file unusable for repositionning in
restore. Many thanks to Kenneth Porter <shiva@sewingwitch.com>
for the bug report and the testing of the fix.
11. Fix EA restoration in debug mode (Sourceforge bug #1986216).
12. Stefan Auracher <star7@onlinehome.de> noticed that the Tower
of Hanoi backup strategy documented in the man page wasn't
actually based on the Tower of Hanoi algorithm. The man page
was updated accordingly.
13. Fix missing level information from dump output when using
the default level (RedHat bug #493635). Thanks to Adam Tkac
<atkac@redhat.com> for the patch.
14. Fix the dump man page to reflect the fact that the default
dump level is 0 not 9 (RedHat bug #356121). Thanks to Adam Tkac
<atkac@redhat.com> for the patch.
15. Fixed a few spelling errors in the man pages (RedHat bug #489853).
Thanks to Adam Tkac <atkac@redhat.com> for the patch.
16. Fixed restore man page and program usage which incorrectly stated
that -P and -A were both allowed in the same invocation (RedHat
bug #490627). Thanks to Adam Tkac <atkac@redhat.com> for the patch.
17. Use sys_clone under Linux to share I/O contexts between dump
processes, thus drastically increasing the performance of dump
under CFQ (which is the default I/O scheduler used in a number of
distributions). Thanks to Jeff Moyer <jmoyer@redhat.com> for the
patch.
18. Add (preliminary) ext4 support - thanks to libext2fs which does
all the job for us. Thanks to Gertjan van Wingerde
<gwingerde@gmail.com> for the patch.
Changes between versions 0.4b40 and 0.4b41 (released January 2, 2006)
=====================================================================
1. Fix restore of dumped Access Control Lists. The previous
code for EA works fine, but ACLs needed conversion from the
ext2/3 disk format to posix_acl format before restoring.
2. Fix some issues with restoration of EA on big endian
platforms.
3. Fix restore when the symtab is over 2GB in size.
4. Made the directory hash indexing an optional feature,
accessible by the '-H' option of restore, and disable it
by default.
5. Fixed dump to not include extended attributes information
in the toc (archive) file which confused restore -t.
Changes between versions 0.4b39 and 0.4b40 (released May 2, 2005)
=================================================================
1. Changed restore to emit warnings (instead of emitting a fatal
error) if a file (or a directory) is unavailable for a
comparision (if the user doesn't have the necessary permissions
to access it for example). Thanks to Kenneth Porter
<shiva@sewingwitch.com> for the bug report.
2. Re-done the 'do not save directory entries to non-dumped inodes
(excluded from dump)' feature. The previous implementation
worked well for excluded directories but not for regular files.
Thanks to Kenneth Porter <shiva@sewingwitch.com> for the bug
report.
3. Fixed a bug in dump where the tape size was miscalculated when
the user used -d/-s to specify the tape characteristics. Thanks
to Philip Goisman <goisman@physics.arizona.edu> for reporting
the bug.
4. Fixed another bug introduced in restore with the hashtree
implementation. This one caused restore to stop saying
"removenode: non-empty directory" in some cases.
5. Added support for dumping and restoring ext2/3 extended
attributes (EA), like the access control lists (ACL) or
the security labels used by SELinux.
Changes between versions 0.4b38 and 0.4b39 (released January 21, 2005)
======================================================================
1. The newly added dump_on_cd_3 example was buggy, replace it
with an updated version from Andrew Basterfield
<bob@cemetery.homeunix.org>.
2. Made restore to chdir() back into the initial directory when
dumping core while aborting a comparision operation. The
previous behaviour was to write the corefile at the root of
the directory being compared, which could very well be
read only and preventing the corefile generation. Thanks
to Kenneth Porter <shiva@sewingwitch.com> for the bug report.
3. Silenced the failure to call fgetflags() when comparing an
entry which has no ext2 attributes (as in lsattr()).
4. Fix a brown paper bug in restore -C which broke restore and
caused modifications on the filesystem being compared
(directories containing a file with the same name as the
directory get renamed to RSTTMP...). Thanks to Kenneth Porter
<shiva@sewingwitch.com> for finding the bug and helping me
reproduce it.
5. Made restore -C force the -N flag (no writing allowed on
the disk) in order to prevent more bugs like the above one.
Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
=====================================================================
1. Fix a couple of troff syntax bugs in the man pages.
Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
2. Made restore use either libncurses or libtermcap, depending
on which one is available at configure time.
3. Fixed restore negative size display bug when comparing a
dump containing files over 2GB. Thanks to Steve Bonds
<sbonds@users.sourceforge.net> for the bug report.
4. Do not save directory entries to non-dumped inodes
(excluded from dump). This will eliminate the 'missing
file' warnings when doing 'restore -C'.
5. Fix dump crash when backuping a huge (2TB) filesystem,
due to a bogus calculation on the inode map size.
Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
submitting the bug and testing the fix.
6. Fix a problem in restore where the final \0 in the symbolic
link names could have been lost, generating corrupt filenames.
Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
bug.
7. Implemented a hash list for the directory names in restore.
The linear list used before caused problems in interactive
restores when dealing with directories having thousands of
entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
for reporting the bug.
8. Improved restore -C, this time including the directory
attributes into the comparision.
9. Made restore understand tapes containing EA/ACLs (which will
be dumped by the next version of dump). In this version
extended attributes on the tape are ignored, for full EA/ACL
support wait for the next version or try the experimental EA
patch.
Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
==================================================================
1. Added the --enable-staticz configure option which enables
dump and restore to be linked with static versions of
libz and libbz2 (and dynamic versions of all other libraries).
This will make Debian users happy, because libz and libbz2
were the only needed libraries living in /usr, all the
others live in /lib. In case of system emergency, it is
better not to have to rely on an extra filesystem.
Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
2. Fix compilation on (at least the Linux Debian port to) AMD64.
(<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
that are also defined by <linux/types.h> (<asm/types.h>) and
they conflict).
3. Make dump's reading of the dumpdates file a bit more robust,
preventing dump from crashing when the dumpdates file has
been modified by hand.
4. Fixed some offset calculations in dump code which could
lead to "bread lseek errors" on large filesystems. Thanks
to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
reporting this bug and debugging the issue.
5. Made dump use the blkid library when searching for devices
by label or uuid instead of dump's own routines.
6. Corrected a bug in dump where a wrong LABEL=... line in
/etc/fstab could prevent dump from dumping unrelated
filesystems. Thanks to Bruce Lowekamp
<lowekamp@users.sourceforge.net> for reporting the bug.
Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
====================================================================
1. Fixed dump compilation with old gcc versions. Thanks to
Mike Castle <dalgoda@users.sourceforge.net> for the patch.
2. Fixed some warnings (howmany, roundup, powerof2 redefined)
when compiling against a recent glibc version.
3. Fixed a bug in restore preventing the read of a dump tape
written with Solaris 7 ufsdump. Thanks to Patrick Higgins
<phiggins@transzap.com> for reporting the bug and providing
the test case.
4. Changed dump to enable the creation of volumes of different
sizes in a single run (make -B accept a list of values).
Patch contributed by Florian Zumbiehl <florz@gmx.de>.
5. Use the glibc provided minor() and major() macros instead
of our own bitmask implementation. This should be safe for
when the major/minor namespace will migrate to 32 bits.
Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
the bug.
6. Made explicit in the dump man page that dump will not create
a remote file, it will only write to an already existing one.
7. Another try at making size estimates better again.
8. Put back the inconditional running of the end-of-tape
script which was changed in 0.434 to be run only when -M
or multiple -f were NOT specified. Some users rely on this
feature even when it is combined with -M/-f.
9. Fixed restore when restoring huge backups (where rstdir...
temporary files are over 2GB). Thanks to
Raphael Jaffey <rjaffey@artic.edu> for reporting this,
debugging the issue and making the patch.
10. Made restore understand FreeBSD UFS2 tapes. Thanks to
David <vrtin@users.sourceforge.net> for submitting the bug
and providing a test case.
11. Made dump work with an arbitrary integer level (no more 10
levels only limitation). Thanks to Matthew
<msvincen@midway.uchicago.edu> for the patch.
Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
=======================================================================
1. Added a note in the dump man page saying that the default
blocksize can be 32 if -d is used with a high density argument.
Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
for the patch.
2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
LDFLAGS environment variables. Thanks to Arcady Genkin
<antipode@users.sourceforge.net> for reporting the bug.
3. Made -e/-E options of dump accept an unlimited number of inodes
to be excluded, rather than a hardcoded maximum. Thanks to
Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
and -D_USE_BSD_SIGNAL defines in configure in order to solve
64bit build problems because quad_t is redifined with a
different signature. Thanks to Mike Harris <mharris@redhat.com>
for reporting this bug.
5. Made restore build on Solaris, making possible to
restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
<uwe@ugsoft.de> for the patch.
6. Made an extension in the dump tape format capable of saving
MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
wrote the extension and contributed the restore code back
into this codebase. The same extension mechanism will be
used in the future to save ACLs...
7. Made rmt work correctly with regard to QFA and local/remote
files and tapes. The remote access will however work only
when the dump provided rmt version is used. If you want to
use another rmt server, please do not use the QFA feature.
Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
====================================================================
1. Fixed the INSTALL file to reflect the actual install paths.
Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
reporting the bug.
2. Fixed the configure script to only check for headers presence
instead of trying to compile them. This should fix issues
with old build environments. Thanks to Kari Lempiainen
<kari@funky.pp.fi> for reporting the bug.
3. Fixed restore to correctly ignore sockets when comparing
a dump (as socket cannot be properly restored anyway). Thanks
to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
4. Fixed restore to correctly access the archive file (-A argument)
even when using a remote tape. Thanks to Fabrice Bellet
<fabrice@bellet.info> for reporting the bug.
5. Fixed (again) handling of long (largefile) seeks in rmt.
Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
the bug.
6. Fixed restore corner case when dealing with large block sizes
dump is able to write now (-b 1024). Thanks to Fabrice Bellet
<fabrice@bellet.info> for reporting the bug.
7. Fixed a bug preventing dump to access a filesystem having
a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
for reporting the bug.
8. Made dump store dump dates using explicit timezones, fixing a
problem with incremental dumps if the timezone is modified
between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
the bug report and the patch.
9. Fixed a bug encountered when dumping individual files (not full
filesystems or directories) and dangling symbolic links happen
to be in the list of files. For as far as dump is concerned,
dangling symbolic links are allowed, and are dumped as is.
Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
bug and providing the fix.
10. Fixed open and creation modes and permissions for QFA and
table-of-contents files in dump and restore. Thanks to
Philippe Troin <phil@fifi.org> for the patch.
11. Fixed the archive file descriptor handling enabling it to be 0.
This can happen in some cases when shell redirections are used.
Thanks to Philippe Troin <phil@fifi.org> for the patch.
12. Delayed the opening of archive file until after suid had been
dropped (fixing a possible security issue if dump is suid).
Thanks to Philippe Troin <phil@fifi.org> for the patch.
13. Fixed the 'S' command handling in the rmt client part.
Thanks to Philippe Troin <phil@fifi.org> for the patch.
14. Modified the end-of-tape script handling to print out statistics
(and stop the timer) before launching the eot script. Also, the eot
script does not get run anymore when using -M (which makes sense) or
when multiple tapes are listed on the command line
(-f tape0,tape1,tapen) (which also makes sense).
Thanks to Philippe Troin <phil@fifi.org> for the patch.
15. Relicensed dump/restore under the 'revised' BSD license, as per
ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
16. Added LZO compression to dump. This new compression method has
the advantage of being super fast, thus not killing tape streaming
on slow machines. Thanks to Helmut Jarausch
<jarausch@igpm.rwth-aachen.de> for the patch and to
Markus Oberhumer <markus@oberhumer.com> for giving special permission
to include his miniLZO project (GPL licensed) in dump/restore.
17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
<ant@notatla.demon.co.uk> for reporting the bugs.
18. Added a special rmt version which can do encryption when writing
to tape. Read examples/encrypted_rmt/README for details on
how to enable and configure it. Thanks to Ken Lalonde
<ken@globalremit.com> for the patch.
19. Made dump work with 2.5 kernel end of tape early warning semantics.
Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
20. Fixed a bug which caused dump -w|-W not to work anymore, because
the fs_freq and fs_passno fields in /etc/mtab are always set
to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
reporting the bug.
Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
=======================================================================
1. Added a note in the restore man page clarifying the question
'set the permissions on the current directory ?' asked by
restore at the end of treatment in -i and -x modes.
2. Fixed the endianess issues when reading compressed tapes.
Thanks to Dark Force <daq4th@users.sourceforge.net> for
reporting this bug and providing test cases.
3. Fixed the "ACL won't be dumped" warning message (which showed
an extra, unrelated error message). Thanks to Dragan Krnic
<dkrnic@lycos.com> for reporting this bug.
4. Made dump look first into /etc/mtab, then into /etc/fstab
when searching for filesystem paths. Also fixed some problems
caused by binding mounts or multiple block device mounts.
Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
<ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
and #160305, Sourceforge bugs #618699 and #679832).
5. Made dump's -I option accept the value '0' meaning all the
read errors will be ignored. This can be useful when running
dump from unattended sessions (like cron jobs). Thanks to
John I Wang <jiwang@users.sourceforge.net> for the suggestion.
6. Fixed the output of dump to indicate 'blocks' instead of
'tape blocks' in the various messages (blocks are always
1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
made it clearly print the current blocksize at the start of
a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
the suggestions.
7. Made rmt understand long (largefiles) seeks.
8. Fixed build with very old versions of libext2fs, where
EXT2_FT_* constants were undefined.
9. Made dump accept the dumpdates path on the command line
(-D file option) instead of using only the hardcoded one.
Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
suggestion.
10. Enabled rmt, LFS, readline, QFA options by default in
./configure. Updated the configure process (new versions
of config.guess, config.sub etc).
Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
=======================================================================
1. Changed dump to use fcntl(F_SETLK) style locking instead
of flock() when locking the dumpdates file. With the old
locking scheme, a local user having read rights on the
dumpdates file could be able to do a Denial of Service attack
on dump. In order to lock the dumpdates file with the new
scheme, the user would need to have write access on the file.
Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
reporting the bug (originally a bugtraq post).
2. Fixed interactive 'ls' which caused spurious errors warnings
about 'undefined filetypes' detected. Thanks to Jorgen Ostling
<jorgen_ostling@users.sourceforge.net> for reporting this
bug.
3. Fixed dump's estimate when dealing with sparse inodes.
4. Modified dump to allow setting a blocksize bigger than 32kB
(raised the limit to 1024kB), because newer hardware needs
this for proper operation. Thanks to Dirk Traenapp
<dtraenapp@users.sourceforge.net> for reporting this.
5. Fixed a bug causing Dump to stop and report an error if an
inode number in the exclude file was followed by some amount
of whitespace. Thanks to Jeffrey Sofferin
<sofferin@users.sourceforge.net> for reporting this bug.
6. Fixed a bug which caused restore, in some particular cases,
to ask some 'scary' questions and leave a bunch of RSTTMP
directories behind when restoring incremental tapes. Thanks
to Philippe Troin <phil@fifi.org> for reporting this bug and
providing the test cases.
7. Changed the wording when inodes are excluded from dump:
replaced 'Added inode 7 to exclude list' with
'Excluding inode 7 (resize inode) from dump', as suggested
by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
===================================================================
1. Fixed rmt open flags transmission (GNU's symbolic syntax over
rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
<eros@lamel.bo.cnr.it> for reporting the bug.
Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
===================================================================
1. Made dump print out the ext2 logical block number in case of a read
error, which can be given as an argument to debugfs' ncheck command,
in order to find out the affected inode. Added note about this
usage in dump's man page.
2. Fixed a problem in restore when reading tapes written on big
endian machines with very old versions of dump. The patch was
contributed by George Helffrich <george@geology.bristol.ac.uk>.
3. Fixed the tape length calculation when using large tapes
and compression. Thanks to Georg Lippold
<g_lippold@sourceforge.net> for reporting the bug.
4. Added a new set of examples in dump_on_cd_2 directory, based
on dump_on_cd examples but somewhat enhanced, supporting DVD
media, and localized in english and german. Thanks to
Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
5. Made dump save 32 bit UID/GID. Internally, this was achieved
by switching from the old BSD inode format to the new BSD
inode format, which means that the tape format was changed.
However, since all restore versions out there should
transparently support both inode formats, the change should
have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
reporting the bug.
6. Fixed a lot of warnings in the code shown when compiling
with 'gcc -W'. Thanks to Matthias Andree
<matthias.andree@stud.uni-dortmund.de> for reporting this.
7. Fixed a small markup bug in the dump man page. Thanks to
Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
patch.
8. Rewrote entirely the man pages using the tmac.an macro
package (Linux man page format) instead of the original BSD
format. They should be now cleaner and easier to modify.
Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
==================================================================
1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
non Linux clients were misinterpreted. The description of the problem
(incompatible numbering in Linux mtio opcodes) is documented at
ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
providing an excellent, cross-platform replacement for rmt in his
star package.
2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
which caused restore to fail when the inode maps were not entirely
contained on the first volume (when using really small volumes or
when dumping a huge number of inodes).
3. Fixed a problem in dump, where files in subdirectories of directories
that have the nodump flag set (or being excluded with -e/-E) were
sometimes incorrectly dumped (instead of being excluded). The original
fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
help testing the patch.
4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
which makes one able to pipe the output of dump, by the net, to
a remote CD-burner server.
5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
and use GNU's symbolic syntax over rmt instead of numerical values
to assure multiple platform compatibility.
6. Documented the -d option in restore.
7. Added a -v (verbose) mode to dump. For now it just prints the number
of the inode being dumped, but this could evolve in future versions
to include interesting debugging output.
8. Added a -o flag to restore, which automatically restores the current
directory permissions in -i or -x mode, without asking the operator
whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
and Peter Samuel <peters@e-smith.com>.
Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
====================================================================
1. Fixed a bug in the QFA feature which could have caused
a bad tape positionning on restore (causing extra delays in
restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
2. Added a small note in the dump man page specifying that
there should be no white space between the option letter and
the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
3. Made restore work with older versions of the readline library,
by checking in configure for several extended symbols. Restore
can now be compiled with a readline as old as the 2.0 release
(though it may be a good idea to upgrade it to a more recent
version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
reporting the build failures.
4. Fixed a performance problem with the QFA file creation in
dump, which made unnecessary seeks on the tape slowing down
the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
reporting this issue.
5. Removed the inclusion of some kernel headers in the dump
source, which prevented the compile in some kernel/glibc
headers/architecture combination. Thanks to Bdale Garbee
<bdale@gag.com> for reporting the bug.
6. Added the appropriate error message when dump fails to
open the output file for writing. Thanks to Amith Varghese
<amithv@yahoo.com> for reporting this bug.
7. Made restore able to understand large Solaris ufsdump tapes
(containing inodes bigger than 4194304). Sun have introduced
an "extension" to the dump tape format when dealing with
those inodes, which was uncorrectly handled by Linux restore.
Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
providing a test case.
8. Added the -m parameter to dump which optimises the output for
inodes having been changed but not modified since the last dump
('changed' and 'modified' have the meaning defined in stat(2)).
For those inodes, dump will save only the metadata, instead of
saving the entire inode contents. Inodes which are either
directories or have been modified since the last dump are saved
in a regular way. Uses of this flag must be consistent, meaning
that either every dump in an incremental dump set have the flag,
or no one has it.
Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
=======================================================================
1. Fixed behaviour of dump when exceeding resource limits
(SIGXFSZ treatment).
2. Added the -L flag to restore to allow the user to specify a
maximal allowed number of miscompares when using restore
with the -C option to check the backup.
3. Detailed the manual entry for the -N option of restore.
4. Added the -a flag to restore to make able doing unattended
restores in -i or -x mode (automatically walks through the
multiple dump volumes).
5. Extended the QFA mode to work with local files and/or
remote tapes and files. This way, restore can know in advance
the tape number and the offset for the inodes to extract and
can minimize the extraction time by seeking directly to the
good tape/offset.
6. Added the -A <archive> option to both dump and restore,
which makes dump to archive a dump table-of-contents in
the specified file to be used by restore to determine
whether a file is in the dump file that is being restored.
(the archive file syntax is also compatible with the
Solaris ufsdump generated one).
7. Small fix in restore making it able to read some (broken ?)
Solaris ufsdump tapes.
8. Fixed dump to correctly recognise the root filesystem when using
ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
for reporting this bug.
9. Added the -P <file> option to restore to create a
Quick File Access file from an already made dump. Patch
contributed by Uwe Gohlke <uwe@ugsoft.de>.
10. Made restore compile and run on Solaris, making it a
possible replacement for the standard ufsrestore. Port was
contributed by Uwe Gohlke <uwe@ugsoft.de>.
Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
=====================================================================
1. Added a set of backup scripts from Eugenio Diaz
<getnito@yahoo.com> in the examples section. It features
automatic (cron based) full and incremental dumping of
several filesystems on a separate filesystem.
2. Fixed a off-by-one miscalculation which disabled dumping
a one letter subdirectory. Thanks to Chris Siebenmann
<cks@utcc.utoronto.ca> for reporting the bug.
3. Fixed several restore bugs occuring when trying to
restore some missing files on the tape. Thanks to Chris
Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
4. Fixed --with-ldopts configure argument passing, installing from
a separate object directory, makefile cleanups contributed
by <splite@purdue.edu>.
5. Fix a bug which could caused, in some conditions, the highest
number inode of a filesystem, to not be dumped. Many thanks
to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
chase this bug.
Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
=======================================================================
1. Added a mini howto from Patrick Walsh in the examples
directory.
2. Minor man pages syntax corrections. Thanks to
Chris Danis <screechco@home.com> for reporting the bugs.
3. Added a script from David B. Peterson <dave@toppledwagon.com>
to the examples section. It features dumping several
filesystems to a remote tape drive upon ssh.
4. Added a patch provided by Richard Jones <rich@annexia.org>
which allows BRADEMAX (number of read errors tolerated by
dump) to be adjusted using the -I option.
5. Fixed a bug which disabled doing "restore -C -f -". Thanks
to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
patch.
6. Add the -l option to restore to specify if, when doing a
remote restore, the file used to access the backup is a
regular file (the defaults being a tape drive). Restore needs
to know this information when reading a remote compressed
dump. Previously, this information was autodetected, but
the autodetection code fails (with ioctl: Inappropriate ioctl
for device) when using a non Linux remote box. Thanks to
many users and especially to Eros Albertazzi
<eros@lamel.bo.cnr.it> for reporting this.
7. Found a workaroung for the dump deadlock problem (3 childs
stuck in pause(), father in read()). The workaround seems
to work for me and several beta-testers. If it doesn't work
for you, please report back.
8. Updated the RPM spec file (BuildPrereq, URL etc).
Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
========================================================================
1. Fixed the permissions of a newly created QFA file by dump.
2. Cleaned up the source of dump (the external variables
definition was a complete mess, making possible to have
objects overlap).
3. Fixed restore to use the full tape volume path when doing
a compare (since it changes the working directory to the
filesystem being compared in the process).
4. Added the -q option to dump which makes dump abort
whenever it needs operator attention. It should be
easier to use dump in scripts with this option.
5. Detect the use of incompatible options to dump and
refuse them (like -a and -B options together).
6. Added bzip2 compression to dump/restore (use option -j level
to select it). Note that you will need a restore version
>= 0.4b24 in order to restore a bzip2 compressed dump.
The same warning as for the zlib compression applies:
the tape format of a bzip2 dump is not compatible with the
original BSD tape format.
7. Fixed a overflow problem in dump corrupting the dump when
very large files were encountered. Thanks to Vladimir Nadvornik
for the bug report.
8. Added a ioctl(BLKFLSBUF) in dump which should flush the
kernel buffer/page cache before starting the dump, helping
a bit those who use dump on mounted filesystems. Thanks to
John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
for this suggestion.
9. Updated the RPM spec file following the RedHat changes
(dynamically linked binaries now in /usr/sbin etc).
10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
which enables restore to recognise multi volume compressed dumps
done on CD. Included his scripts for dump (which pipe the dump
output directly into cdrecord) and restore. There is now
possible to to backups to CD on the fly!
Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
===================================================================
1. Fixed a buffer overflow in restore/tape.c. Patch provided by
Marcus Meissner (Caldera International Security Dept.).
2. Implement the Sun rmt extended protocol. Patch submitted
by Ian Gordon <iangordon@users.sourceforge.net>.
3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
the linux kernel header. This ensures that dump always has the
latest version of this file. Patch submitted by
Andreas Dilger <adilger@turbolinux.com>.
4. Report any filesystem present in either /etc/fstab with a
positive passno or /etc/dumpdates in dump -w output.
Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
5. Fixed the looping problem in dump introduced in the
previous version.
6. Changed the -B option of dump to limit the size of
_compressed_ output per volume if compression is on.
Patch contributed by Helmut Jarausch
<jarausch@igpm.rwth-aachen.de>. Note however that, since
it is impossible to predict the size of the compressed
data before doing the compression, the -B limit is a bit
conservative.
7. Fixed a bug in reading the operator typed file/tape path for
the next volume in restore.
8. Implemented a "-F script" option to restore which permits the
user to specify a script which will be launched at the
beginning of each tape, useful for automatic programming of
tape changers for example. See the restore man page for the
script parameters and return codes.
9. Small fix for the QFA routines provided by Uwe Gohlke
<uwe@ugsoft.de>, and some recommendations for QFA uses in
the man pages.
10. Fixed the multivolume restoring where making a mistake
to the 'Mount next tape' prompt caused several blocks to
be lost.
11. Enhanced the -e option of dump to take as a parameter a
comma separated list of inode numbers.
12. Added the -E option to dump which specify a file containing
inode numbers to exclude from the dump.
13. Fixed the compressed multi-volume dump + restore.
Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
==================================================================
1. Made dump report the number of blocks dumped per volume.
Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
2. Fix a bug in dump where waiting too much at the 'change volumes'
question caused the volume to be rewritten. Thanks to
Graham Reed <greed@users.sourceforge.net> for reporting the
bug and providing a patch.
3. Added a compression option to dump, contributed by Jerry
Peters <gapeters@worldnet.att.net>.
WARNING: the compression works only on files/pipes and
drives supporting variable block size.
WARNING2: tapes created using the compression feature are
incompatible with the standard dump tape format, and a
version of restore >= 0.4b22 will be needed for extraction.
4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
architectures. Thanks to Paul Slootman <paul@debian.org> for
the patch and to Bdale Garbee <bdale@gag.com> for forwarding
it upstream.
5. Many cleanups (CPP defines, const char warnings, check of
ext2fs COMPAT flags, time_t cleanups, added libext2 version
in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
6. Made --prefix option work in configure. All the install path
are now based on the configure parameters.
7. Added the Quick File Access mode in dump/restore, contributed
by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
a file tape position for each inode, and this file is used by
restore (if called with parameter Q and the filename)
to directly position the tape at the file restore is currently
working on. This saves hours when restoring single files from
large backups, saves the tapes and the drive's head. Use
--enable-qfa option of configure to compile in the QFA support.
8. Added the possibility to dump several files and directories
in a single invocation of dump. Thanks to Uwe Gohlke
<uwe@ugsoft.de> for implementing this option.
9. Fixed the dumping and restoring of files with holes
(files ending with holes didn't get dumped or restored
correctly).
10. Fixed a socket descriptor leak in dump, which leaved opened
3 file descriptors per dump process (and there is one dump
process per tape).
11. Fixed dump large file system support, by explicit use of
open64/lseek64/etc functions (explicit use needed because
e2fsprogs libraries don't behave well when compiled with
FILE_OFFSET_BITS=64).
Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
======================================================================
1. Fixed some bugs in the dump -w|-W logic introduced by
the previous version. Thanks to Andreas Dilger
<adilger@turbolinux.com> for his help on this one.
2. Fixed again a compilation problem when using old e2fs
headers (filesystem label related). Thanks to many users
who reported this stupid error.
3. Fixed a build problem on old lib5 based systems dealing with
_PATH_MNTTAB being undefined. Thanks to John Adams
<johna@onevista.com> for reporting the bug.
4. Improved the error detection in restore when creating
the temporary files in TMPDIR. Now restore will corectly
report a 'no space left on device' error instead of
strange errors which could imply an archive corruption.
Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
bgjenero <bgjenero@sympatico.ca> for reporting the bug.
5. Added the throughput information in dump's progression
messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
for the patch.
6. Use libext2fs's inode scanning routines, which are particularly
robust when dealing with errors (especially when having some
bad blocks on the filesystem). Many thanks to Colin
<colin@horizon.com> for reporting the bug, investigating
the issues, finding a workaround, writing the patch and
fully testing it... (of course, if this patch will break
anything, he is to blame for :-)).
7. Made dump and restore LFS aware. Dump can dump a filesystem
containing large files, generate a large file on output and
restore can restore them. This feature is not enabled by
default, use --enable-largefile option of configure to enable
it (you need to have a LFS aware glibc though). Thanks to
Andrea Arcangeli <andrea@suse.de> for submitting the patch,
and to Theodore T'so <tytso@valinux.com> for his always
useful thoughts.
8. Made dump ask upon a tape write error if it should rewrite
the current volume (assume this is a bad tape) or if it should
assume an end-of-tape condition (useful for tape drives which
behaves badly at the end of the tape). Thanks to Andreas
Dilger <adilger@turbolinux.com> for the suggestion.
Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
=======================================================================
1. Fixed a small compilation problem due to a change
in the definintion of the struct sigaction in
glibc 2.0 / libc5. Thanks to Gunther Schlegel
<schlegel@riege.de> for reporting the bug and to
Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
a fix.
2. Modified the label and uuid analysis in order to be
self-contained (independant of kernel/libc headers). This
should fix the compile with older kernel/libc headers and
will preserve the functionality. Thanks to Bernhard Erdmann
<bernhard.erdmann@gmx.de> for reporting the bug.
3. The 'exclude inode' option, if applied to a directory
inode, excludes now correctly all the leaves of this
directory. Thanks to John R. Dennison
<gerdesas@users.sourceforge.net> for reporting the bug.
4. Fixed the '-e' option to disable the possibility
to exclude the root inode (which causes the dumps to
be unreadable by restore). Prevented array overflow
when multiple -e options are used.
5. Fixed dump to correctly interpret a filesystem argument
which is a mountpoint and it is not an absolute path
(as specified in the fstab). Thanks to Bernhard R. Erdmann
<be@berdmann.de> for reporting the bug.
6. Made dump able to backup files larger than 2 GB. Note that
dump still doesn't cope with files larger than 4 GB.
7. Restore the real uid and gid before invoking an external
RSH program (big hole when dump or restore is suid root!).
8. Get the values for the default tape device and the location
of fstab file from the system headers. Thanks to
Andreas Dilger <adilger@turbolinux.com> for the patch.
9. Made dump -w|-W report all recognized filesystems
present in either /etc/fstab or /etc/dumpdates, and present
the list in the same order as in fstab file. Thanks
to Andreas Dilger <adilger@turbolinux.com> for the patch.
10. Made dump's -a (automatic end of tape detection) the
default. Specifying one of -B, -c, -d or -s options will
override the EOM detection. Thanks to Andreas Dilger
<adilger@turbolinux.com> for the patch.
11. Save the ext2 filesystem label into the dump volume label.
Specifying a volume label on the command line (-L option)
will override this feature. Thanks to Andreas Dilger
<adilger@turbolinux.com> for the patch.
Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
=====================================================================
1. Fixed the signal handling in dump (which I broke in 0.4b17)
which was causing several strange dump failures (dump
hanged or segmentation faults etc).
2. Specified the default blocksize in the dump man page.
3. Changed two info messages of restore to be written on stdout
instead of stderr in order to leave stderr only for errors
or warnings. Thanks to Stephen Atwell
<satwell@urbana.css.mot.com> for the suggestion.
4. Corrected an off by one calculation which prevented
dumping a directory having a 1 character name length.
Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
for reporting the bug.
5. Reinforce dump in order to allow only level 0 and no
-u option when dumping a subdirectory, and document
this in the man page. Thanks to Bernhard Erdmann
<bernhard.erdmann@gmx.de> for reporting the bug.
6. Fixed a small harmless bug in restore which caused
in some conditions hard links to be restored several
times (therefore generation some warning messages).
Thanks to Kenneth Porter <shiva@well.com> for
reporting the bug.
7. Updated the RPM spec file to the latest RedHat version,
providing FHS packaging and other cosmetic changes.
You will need RPM version >= 3.0.5 in order to build the RPM.
8. Updated the configure script to check for libtermcap
before checking for libreadline, because we need this
library in order to compile the readline support.
9. Made dump understand the LABEL= and UUID= notation
both in /etc/fstab and on the command line. Note that
you will need the /proc filesystem in order to use
these notations. Thanks to Erik Troan <ewt@redhat.com>
for providing the patch.
Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
===================================================================
1. Fixed a potential buffer overflow in restore. Thanks
to Stan Bubrouski <satan@fastdial.net> for reporting
the bug.
2. Fixed a readline-related bug which prevented
'cat DUMPFILE | restore -i -f -' from working. Thanks
to Charles Karney <karney@users.sourceforge.net>
for the bug report.
3. Changed a few "panic" into "exit", causing restore to
be more stable against some attacks (like the last one
reported on Bugtraq, although the last version of restore
was not vulnerable - just dumped core). Thanks to
Andreas Hasenack <andreas@conectiva.com.br> for reporting
the bugs to me.
4. Removed the suid-root bit on dump and restore in the
default build (and generated RPMs). It should be safer
now. Users who need the suid-root capabilities in order
to make network backups should read first the man page
of dump and enable the suid bit manually.
5. Added -ltermcap to the compile parameters for restore
when using readline support, in order to make the compile
process work on some systems (SuSE ?). Thanks to
Patrik Schindler <poc@pocnet.net> for reporting the bug.
Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
====================================================================
1. The -F script is called now *only* at the end of a tape,
not at the end of the dump. Thanks to Christian Haul
<haul@informatik.tu-darmstadt.de> for the bug report.
Normally, the device name and the current volume number
are passed on the command line of the script. However,
if you want the old style script (with no arguments
passed on the command line), you can enable it in
configure with the --enable-oldstylefscript.
2. Use posix signal handling to preserve dump functionality
with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
the patch.
3. Made the exit code of restore in case of a 'C'ompare
command reflect the result of the compare. An exit status
of 0 means the dump archive is correct, 1 means tape errors,
2 means that some files were modified. Thanks to Kenneth Porter
<shiva@well.com> for the suggestion.
4. Made (finally) quotes work in interactive restore.
5. Small fixes in order to allow dump to compile with a
really old e2fsprogs version. Thanks to Ian Zimmerman
<itz@speakeasy.org> for the bug report.
6. Add GNU readline capabilities to interactive restore.
Use configure's --enable-readline flag to enable this feature.
Thanks to Patrik Schindler <poc@pocnet.net> for the
suggestion.
7. Do the compare on the fly in restore 'C' mode (this will
allow not to exhaust the available /tmp space when
ccmparing large files). Thanks to Kenneth Porter
<shiva@well.com> for the suggestion.
Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
====================================================================
1. Fixed some several duplicate 'DUMP: DUMP:' in the
output of dump.
2. Corrected the estimation of blocks to dump. Note that
this is still wrong for large directory inodes, due
to the size of a BSD directory entry on the tape
(estimation is based on the size of the ext2 directory,
which is smaller because it doesn't contain the null
character at the end).
3. Made dump report the total number of MB written to
tape at the end of run. Thanks to W. Reilly Cooley
<wcooley@nakedape.cc> for the patch.
4. Added the -X option to restore giving the possibility
to read the names of the files to be extracted/listed
from a text file (in addition of the command line).
Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
patch.
5. Added the device name and the current volume number
as arguments to the end of tape script (dump -F option).
6. Made the multi-volume dump work again (after having
broken it in 0.4b15).
Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
===================================================================
1. Added a prompt command in interactive restore mode. Thanks
to Andreas Dilger <adilger@home.com> for the patch.
2. Fixed a buffer overflow problem in dump (caused by
not checking the size of the filesystem parameter).
Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
reporting this on Bugtraq (and to several dump users
who forwarded me his mail).
3. Added the '-F script' option to dump in order to
launch a script at the end of each tape (to be used
with a tape changer, or to notify the sysadmin by
pager etc.).
4. Fixed a bug in restore compare code caused by the changes
I made in 0.4b14.
5. Fixed the treatment of options using the old BSD syntax
in both dump and restore.
Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
=======================================================================
1. Fixed a bug in dump which may have caused invalid deleted
directories to be dumped out if they were deleted after the
mapping pass. This could occure on active filesystem and lead
to heap corruption (causing dump malfunction in many possible ways).
Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
bug and submitting the patch.
2. Fixed the handling of the filesystem parameter in dump. A
'/mnt/disk' parameter caused the disk contents to be dumped,
but a '/mnt/disk/' parameter caused the mountpoint directory
to be dumped (generally an empty directory).
3. Improved the output of dump in order to tell which directory
it is currently dumping (when dumping a subtree).
4. Added the '-e' exclude inode option to dump. Thanks to
Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
5. Added a REPORTING-BUGS file in order to provide a guide
on how to correctly report a bug in dump/restore.
6. Fixed a restore problem when restoring a hard link to an inode
having the immutable or append-only attribute set. Thanks to
Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
7. Fixed a compatibility problem between dumps made on little
endian machines (the format was correct) and big endian
machines (the format was incorrect). This fix break the
compatibility with the older dumps made on big endian
machines (sparc, m86k, ppc etc). For the first time in
linux dump's history (I believe), the dumps made by *BSD,
Linux/alpha, Linux/sparc and Linux/x86 are compatible,
so interchangeable. Thanks to Rob Cermak
<cermak@ahab.rutgers.edu> for submitting the bug and
helping me test the fix.
8. Fixed the way dump reports the remaining percent/time, if
the number of blocks actually dumped exceeds the estimated
number of blocks. Thanks to Jean-Paul van der Jagt
<jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
======================================================================
1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
<sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
2. Removed the requirement to build the RPM as root from the
spec file. Thanks to Christian Weisgerber
<naddy@mips.rhein-neckar.de> for submitting this.
3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
causing dump to block when dumping really huge filesystems.
Many thanks to Patrik Schindler <poc@pocnet.net> for
helping me find this bug.
4. Fixed the treatment for an interrupt signal when dump access
the remote tape through RSH. Thanks to Christian Weisgerber
<naddy@mips.rhein-neckar.de> for providing the patch.
5. Fixed a bug which was causing dump/restore to display
garbage characters instead of the remote host name.
Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
=====================================================================
1. Small fix in the dump man page. Thanks to Thorsten Kukuk
<kukuk@suse.de> for submitting the patch.
2. Fix for the exit code when using the size estimate option of
dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
submitting the patch.
3. Handle EINTR in atomical reads/writes in dump, which was causing
dump to fail on some systems. Thanks to Eric Jergensen
<eric@dvns.com> for reporting the bug and submitting the patch.
4. Handle more than 16 characters for the device names in dumpdates.
(up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
tracking down the problem and proposing the solution.
5. Fixed a bug in dump which prevented the creation of the
dumpdates file when doing a 0-level dump without already
having a dumpdates file. Thanks to Patrik Schindler
<poc@pocnet.net> for reporting the bug.
6. Changed the way dump 'S' flag reports the size estimate
from number of blocks into bytes (making it compatible
with the Solaris version, and simplifying things for
amanda users). Thanks to Jason L Tibbitts III
<tibbs@math.uh.edu> for reporting the bug.
7. Fixed a compatibility problem in linux/alpha dump tape format.
Now the linux/alpha dump are (again) compatible with the
other dump formats. But this breaks compatibility with
older dumps made on alpha. Thanks to Mike Tibor
<tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
======================================================================
1. Added a '--enable-kerberos' to configure.
2. Added a 'S' option to dump which determines the amount of space
that is needed to perform the dump without actually doing it, similar
to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
<cermak@ahab.rutgers.edu>.
3. Added a 'M' multi-volume option to dump and restore which enables
dumping to multiple files (useful when dumping to an ext2
partition to make several dump files in order to bypass the 2GB
file size limitation). The 'f' argument is treated as a prefix and
the output files will be named <prefix>001, <prefix>002 etc. With
the 'M' flag, restore automatically selects the right file without
asking to enter a new tape each time.
4. Fixed a memory leak which was causing dump to grow very big
(270MB when dumping a 10GB filesystem...). Thanks to Jason
Fearon <jasonf@netrider.org.au> for reporting the bug.
Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
======================================================================
1. Make configure test if the system glob routines support
extended syntax (ALTDIRFUNC). If not, use the internal glob
routines instead of system ones. Thanks to Bernhard Sadlowski
<sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
and helping me resolve this and other minor libc5 compiling
glitches.
2. Fix a problem when dumping a ext2fs with the 'filetype'
feature enabled. Thanks to Patrick J. LoPresti
<patl@cag.lcs.mit.edu> for reporting the bug and to
Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
3. Made the nodump flag work on directories. A directory which
has the nodump flag gets never dumped, regardless of its
contents.
4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
which allows dump on an active ext3 filesystem. However, this
is a "quick and dirty" patch which enables backup of an ext3
filesystem through the ext2 compatibility (by ignoring the
NEEDS_RECOVERY bit). The journal file is not recognized and
it is dumped (it should not).
5. Test the superblock compatibility flags when dumping, in order
to be sure that we know how to deal with specific features.
Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
====================================================================
1. Use lchown instead of chown, fixing a possible security problem
when restoring symlinks (a malicious user could use this
to deliberately corrupt the ownership of important system files).
Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
this and providing the patch.
Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
====================================================================
1. Put dump sources under CVS, added Id tags in all files so
one can use 'ident' on binary files.
2. Added the dump/restore version in the usage text so one can
easily verify the version he is using.
3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
a va_start/va_end problem on linux-ppc (always call va_start
va_end in pairs each time we use a vararg function).
4. Added again the DT_* constants because old libc does not
contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
for submitting the bug report.
5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
this should enable dumping big (huge) filesystems.
6. Added the RSH environment variable in order to be able to
use a rsh replacement like ssh when doing remote backups (and
bypass the security limitations of rcmd). Now you can do remote
backups without being root (or making dump setuid root).
7. Modified again the way dumpdates works. For incremental dumps,
we need to read dumpdates even if we are not using 'u' option.
Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
this should work.
Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
===================================================================
1. Removed the 'k' flag from the restore 'about' text if kerberos
was not compiled in.
2. Prototyped (f)setflags from e2fsprogs and corrected the calls
to them (fsetflags takes a char*, setflags an open fd!).
3. (f)setflags is called only if the flags aren't empty. If the
file is a special file, a warning is printed, because changing
flags implies opening the device. Normally, a special file
should not have any flag... (Debian bug #29775, patch provided
by Abhijit Dasgupta <abhijit@ans.net>).
4. Made possible to dump a file system not mentioned in /etc/fstab.
(Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
5. Changed the default behaviour to not create dumpdates
unless 'u' option is specified. Removed the old "debian-patch"
which provided the same thing. (Debian bug #38136, #33818).
6. Removed all those dump*announce, since they were getting old...
7. Added warning messages if dumpdates does not exist and
when an inferior level dump does not exist (except for a level 0
dump).
8. Debugged the glob calls in interactive mode: restore used a
dirent struct which was different from the /usr/include/dirent.h
one (this used to work, is it a glibc2 change?), so none of the
compat glob (which used /usr/include/dirent.h) or the system glob
worked. Restore use now the system dirent (and the system
DT_* constants), which are compatible with BSD ones.
9. Added a configure flag (--with-dumpdatespath) to specify
the location of dumpdates file. By default, it is
/etc/dumpdates.
10. Added the "AUTHOR" and "AVAILABILITY" sections and
included the current date/version in man pages.
11. Corrected the estimation of remaining time when
the operator doesn't change the tapes quickly enough. This
was an old bug, I thought I corrected it, and discovered
that in fact it was corrected in two different places, so
the results canceled each other...
Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
===================================================================
1. Integrated multiple patches from RedHat, Debian and SuSE:
- tweak dump/itime.c to not try to read dumpdates if the 'u' option
isn't specified.
- several fixes in the man pages.
- update the default tape device to /dev/st0.
- many updates for Linux Alpha (byte ordering, size_t etc).
- buffer overruns.
- use environment variable for TMPDIR (instead of /tmp).
- use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
- workaround egcs bug (RedHat bugs #4281 and #2989).
- wire $(OPT) throughout Makefile's.
2. Upgrade the dump revision to 1, making possible to dump filesystems
made with e2fsprogs-1.15 or newer. Nothing seems to break...
3. Fix some compile warnings, prototype all functions.
4. Use glibc err/glob instead of internal compatibility
routines (only if available).
5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
======================================================================
1. Integrated the changes from FreeBSD-3.1-RELEASE
(mostly bug fixes, buffer overruns, dump has now an "automatic
tape length calculation" flag, dump/restore can use kerberos now
(this is NOT tested), use environment variables for TAPE and
RMT etc.).
2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
3. Corrected a bug in restore when using 'C' option with multi-volumes
tapes (files splited accros two tapes give "size changed" errors
when comparing).
4. Corrected the long standing bug when dumping multiple tapes.
This works for me, needs further testing.
Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
====================================================================
1. Dump now runs correctly on kernels 2.1.x
Fix made by Gerald Peters <gapeters@worldnet.att.net>
Changes between versions 0.4b2 and 0.4b3
========================================
1. Use realpath() if available
2. Report statistics
Changes between versions 0.4b1 and 0.4b2
========================================
1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
the patch)
2. Fixed restore to make it able to read FreeBSD 2.x dumps again
3. Fixed configure.in to correctly handle --enable-rmt
Changes between versions 0.3 and 0.4b1
======================================
1. Integrated the changes from 4.4BSD-Lite2
2. Integrated the patches from Debian and Red Hat
3. Portability changes: use the __u32, __u16, __s32, and __s16 types
4. Changed dump to use the Ext2fs library to get block addresses. This
should solve the endianness problem on SparcLinux.
5. Created a configure.in file (shamelessly stolen from the e2fsprogs
distribution's one) to use autoconf
6. Fixed a few minor bugs
Changes between versions 0.2e and 0.2f
======================================
1. Added the creation of named pipes (fifos) in restore.
2. Added the -N flag in the restore manual page.
3. Added the file kernel.patch which contains the llseek() optimization
patch for 1.2.x kernels.
4. Fixed a bug in the restoration of symbolic links: owner and group were
not restored.
5. Integrated some changes from FreeBSD 2.2.
6. Added a call to ftruncate() after restoring each file to restore
correctly files ending by a hole.
Changes between versions 0.2d and 0.2e
======================================
1. Fixed a bug in the "set owner/mode" process. Every file was restored
with owner = root (0) and group = root/wheel/whatever (0).
Changes between versions 0.2c and 0.2d
======================================
1. Dump is now able to backup 2GB+ filesystems.
2. Dump and restore can now be linked as static binaries.
Changes between versions 0.2b and 0.2c
======================================
1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
Changes between versions 0.2a and 0.2b
======================================
1. Really fixed the bug that I should have corrected in 0.2a.
2. Enabled optimization again.
Changes between versions 0.2 and 0.2a
=====================================
1. Disabled the optimization during compilation.
Changes between versions 0.1 and 0.2
====================================
1. Fixed a bug in fstab.c which caused a null pointer to be stored in
the fs_type field (actually, I modified the file fstab.c to make it
use the mntent functions).
2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
made by dump should be readable by the BSD restore and backups made
by the BSD dump should be readable by restore. Unfortunately, this
means that the dump format has changed between version 0.1 and version
0.2 :-(
3. Dump is now able to backup a subtree, it is no longer limited to whole
filesystems like the BSD version.
4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
than 2 GB.
Changes between versions 0.0 and 0.1
====================================
1. Now create links rdump and rrestore during the `make install' step.
2. Linux port specific bugs added to the manual pages
3. Incorrect estimation of the number of tapes blocks fixed when doing
incremental backups.
4. Better ls-like format in restore in interactive mode.
