3 Changes between versions 0.4b20 and 0.4b21 (released ?????????????????)
4 =======================================================================
6 1. Fixed some bugs in the dump -w|-W logic introduced by
7 the previous version. Thanks to Andreas Dilger
8 <adilger@turbolinux.com> for his help on this one.
10 2. Fixed again a compilation problem when using old e2fs
11 headers (filesystem label related). Thanks to many users
12 who reported this stupid error.
14 3. Fixed a build problem on old lib5 based systems dealing with
15 _PATH_MNTTAB being undefined. Thanks to John Adams
16 <johna@onevista.com> for reporting the bug.
18 4. Improved the error detection in restore when creating
19 the temporary files in TMPDIR. Now restore will corectly
20 report a 'no space left on device' error instead of
21 strange errors which could imply an archive corruption.
22 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
23 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
25 5. Added the throughput information in dump's progression
26 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
29 6. Use libext2fs's inode scanning routines, which are particularly
30 robust when dealing with errors (especially when having some
31 bad blocks on the filesystem). Many thanks to Colin
32 <colin@horizon.com> for reporting the bug, investigating
33 the issues, finding a workaround, writing the patch and
34 fully testing it... (of course, if this patch will break
35 anything, he is to blame for :-)).
37 7. Make dump and restore LFS aware. Dump can dump a filesystem
38 containing large files, generate a large file on output and
39 restore can restore them. This feature is not enabled by
40 default, use --enable-largefile option of configure to enable
41 it (you need to have a LFS aware glibc though). Thanks to
42 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
43 and to Theodore T'so <tytso@valinux.com> for his always
46 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
47 =======================================================================
49 1. Fixed a small compilation problem due to a change
50 in the definintion of the struct sigaction in
51 glibc 2.0 / libc5. Thanks to Gunther Schlegel
52 <schlegel@riege.de> for reporting the bug and to
53 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
56 2. Modified the label and uuid analysis in order to be
57 self-contained (independant of kernel/libc headers). This
58 should fix the compile with older kernel/libc headers and
59 will preserve the functionality. Thanks to Bernhard Erdmann
60 <bernhard.erdmann@gmx.de> for reporting the bug.
62 3. The 'exclude inode' option, if applied to a directory
63 inode, excludes now correctly all the leaves of this
64 directory. Thanks to John R. Dennison
65 <gerdesas@users.sourceforge.net> for reporting the bug.
67 4. Fixed the '-e' option to disable the possibility
68 to exclude the root inode (which causes the dumps to
69 be unreadable by restore). Prevented array overflow
70 when multiple -e options are used.
72 5. Fixed dump to correctly interpret a filesystem argument
73 which is a mountpoint and it is not an absolute path
74 (as specified in the fstab). Thanks to Bernhard R. Erdmann
75 <be@berdmann.de> for reporting the bug.
77 6. Made dump able to backup files larger than 2 GB. Note that
78 dump still doesn't cope with files larger than 4 GB.
80 7. Restore the real uid and gid before invoking an external
81 RSH program (big hole when dump or restore is suid root!).
83 8. Get the values for the default tape device and the location
84 of fstab file from the system headers. Thanks to
85 Andreas Dilger <adilger@turbolinux.com> for the patch.
87 9. Made dump -w|-W report all recognized filesystems
88 present in either /etc/fstab or /etc/dumpdates, and present
89 the list in the same order as in fstab file. Thanks
90 to Andreas Dilger <adilger@turbolinux.com> for the patch.
92 10. Made dump's -a (automatic end of tape detection) the
93 default. Specifying one of -B, -c, -d or -s options will
94 override the EOM detection. Thanks to Andreas Dilger
95 <adilger@turbolinux.com> for the patch.
97 11. Save the ext2 filesystem label into the dump volume label.
98 Specifying a volume label on the command line (-L option)
99 will override this feature. Thanks to Andreas Dilger
100 <adilger@turbolinux.com> for the patch.
102 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
103 =====================================================================
105 1. Fixed the signal handling in dump (which I broke in 0.4b17)
106 which was causing several strange dump failures (dump
107 hanged or segmentation faults etc).
109 2. Specified the default blocksize in the dump man page.
111 3. Changed two info messages of restore to be written on stdout
112 instead of stderr in order to leave stderr only for errors
113 or warnings. Thanks to Stephen Atwell
114 <satwell@urbana.css.mot.com> for the suggestion.
116 4. Corrected an off by one calculation which prevented
117 dumping a directory having a 1 character name length.
118 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
119 for reporting the bug.
121 5. Reinforce dump in order to allow only level 0 and no
122 -u option when dumping a subdirectory, and document
123 this in the man page. Thanks to Bernhard Erdmann
124 <bernhard.erdmann@gmx.de> for reporting the bug.
126 6. Fixed a small harmless bug in restore which caused
127 in some conditions hard links to be restored several
128 times (therefore generation some warning messages).
129 Thanks to Kenneth Porter <shiva@well.com> for
132 7. Updated the RPM spec file to the latest RedHat version,
133 providing FHS packaging and other cosmetic changes.
134 You will need RPM version >= 3.0.5 in order to build the RPM.
136 8. Updated the configure script to check for libtermcap
137 before checking for libreadline, because we need this
138 library in order to compile the readline support.
140 9. Made dump understand the LABEL= and UUID= notation
141 both in /etc/fstab and on the command line. Note that
142 you will need the /proc filesystem in order to use
143 these notations. Thanks to Erik Troan <ewt@redhat.com>
144 for providing the patch.
146 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
147 ===================================================================
149 1. Fixed a potential buffer overflow in restore. Thanks
150 to Stan Bubrouski <satan@fastdial.net> for reporting
153 2. Fixed a readline-related bug which prevented
154 'cat DUMPFILE | restore -i -f -' from working. Thanks
155 to Charles Karney <karney@users.sourceforge.net>
158 3. Changed a few "panic" into "exit", causing restore to
159 be more stable against some attacks (like the last one
160 reported on Bugtraq, although the last version of restore
161 was not vulnerable - just dumped core). Thanks to
162 Andreas Hasenack <andreas@conectiva.com.br> for reporting
165 4. Removed the suid-root bit on dump and restore in the
166 default build (and generated RPMs). It should be safer
167 now. Users who need the suid-root capabilities in order
168 to make network backups should read first the man page
169 of dump and enable the suid bit manually.
171 5. Added -ltermcap to the compile parameters for restore
172 when using readline support, in order to make the compile
173 process work on some systems (SuSE ?). Thanks to
174 Patrik Schindler <poc@pocnet.net> for reporting the bug.
176 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
177 ====================================================================
179 1. The -F script is called now *only* at the end of a tape,
180 not at the end of the dump. Thanks to Christian Haul
181 <haul@informatik.tu-darmstadt.de> for the bug report.
183 Normally, the device name and the current volume number
184 are passed on the command line of the script. However,
185 if you want the old style script (with no arguments
186 passed on the command line), you can enable it in
187 configure with the --enable-oldstylefscript.
189 2. Use posix signal handling to preserve dump functionality
190 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
193 3. Made the exit code of restore in case of a 'C'ompare
194 command reflect the result of the compare. An exit status
195 of 0 means the dump archive is correct, 1 means tape errors,
196 2 means that some files were modified. Thanks to Kenneth Porter
197 <shiva@well.com> for the suggestion.
199 4. Made (finally) quotes work in interactive restore.
201 5. Small fixes in order to allow dump to compile with a
202 really old e2fsprogs version. Thanks to Ian Zimmerman
203 <itz@speakeasy.org> for the bug report.
205 6. Add GNU readline capabilities to interactive restore.
206 Use configure's --enable-readline flag to enable this feature.
207 Thanks to Patrik Schindler <poc@pocnet.net> for the
210 7. Do the compare on the fly in restore 'C' mode (this will
211 allow not to exhaust the available /tmp space when
212 ccmparing large files). Thanks to Kenneth Porter
213 <shiva@well.com> for the suggestion.
215 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
216 ====================================================================
218 1. Fixed some several duplicate 'DUMP: DUMP:' in the
221 2. Corrected the estimation of blocks to dump. Note that
222 this is still wrong for large directory inodes, due
223 to the size of a BSD directory entry on the tape
224 (estimation is based on the size of the ext2 directory,
225 which is smaller because it doesn't contain the null
226 character at the end).
228 3. Made dump report the total number of MB written to
229 tape at the end of run. Thanks to W. Reilly Cooley
230 <wcooley@nakedape.cc> for the patch.
232 4. Added the -X option to restore giving the possibility
233 to read the names of the files to be extracted/listed
234 from a text file (in addition of the command line).
235 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
238 5. Added the device name and the current volume number
239 as arguments to the end of tape script (dump -F option).
241 6. Made the multi-volume dump work again (after having
242 broken it in 0.4b15).
244 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
245 ===================================================================
247 1. Added a prompt command in interactive restore mode. Thanks
248 to Andreas Dilger <adilger@home.com> for the patch.
250 2. Fixed a buffer overflow problem in dump (caused by
251 not checking the size of the filesystem parameter).
252 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
253 reporting this on Bugtraq (and to several dump users
254 who forwarded me his mail).
256 3. Added the '-F script' option to dump in order to
257 launch a script at the end of each tape (to be used
258 with a tape changer, or to notify the sysadmin by
261 4. Fixed a bug in restore compare code caused by the changes
264 5. Fixed the treatment of options using the old BSD syntax
265 in both dump and restore.
267 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
268 =======================================================================
270 1. Fixed a bug in dump which may have caused invalid deleted
271 directories to be dumped out if they were deleted after the
272 mapping pass. This could occure on active filesystem and lead
273 to heap corruption (causing dump malfunction in many possible ways).
274 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
275 bug and submitting the patch.
277 2. Fixed the handling of the filesystem parameter in dump. A
278 '/mnt/disk' parameter caused the disk contents to be dumped,
279 but a '/mnt/disk/' parameter caused the mountpoint directory
280 to be dumped (generally an empty directory).
282 3. Improved the output of dump in order to tell which directory
283 it is currently dumping (when dumping a subtree).
285 4. Added the '-e' exclude inode option to dump. Thanks to
286 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
288 5. Added a REPORTING-BUGS file in order to provide a guide
289 on how to correctly report a bug in dump/restore.
291 6. Fixed a restore problem when restoring a hard link to an inode
292 having the immutable or append-only attribute set. Thanks to
293 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
295 7. Fixed a compatibility problem between dumps made on little
296 endian machines (the format was correct) and big endian
297 machines (the format was incorrect). This fix break the
298 compatibility with the older dumps made on big endian
299 machines (sparc, m86k, ppc etc). For the first time in
300 linux dump's history (I believe), the dumps made by *BSD,
301 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
302 so interchangeable. Thanks to Rob Cermak
303 <cermak@ahab.rutgers.edu> for submitting the bug and
304 helping me test the fix.
306 8. Fixed the way dump reports the remaining percent/time, if
307 the number of blocks actually dumped exceeds the estimated
308 number of blocks. Thanks to Jean-Paul van der Jagt
309 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
311 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
312 ======================================================================
314 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
315 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
317 2. Removed the requirement to build the RPM as root from the
318 spec file. Thanks to Christian Weisgerber
319 <naddy@mips.rhein-neckar.de> for submitting this.
321 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
322 causing dump to block when dumping really huge filesystems.
323 Many thanks to Patrik Schindler <poc@pocnet.net> for
324 helping me find this bug.
326 4. Fixed the treatment for an interrupt signal when dump access
327 the remote tape through RSH. Thanks to Christian Weisgerber
328 <naddy@mips.rhein-neckar.de> for providing the patch.
330 5. Fixed a bug which was causing dump/restore to display
331 garbage characters instead of the remote host name.
333 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
334 =====================================================================
336 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
337 <kukuk@suse.de> for submitting the patch.
339 2. Fix for the exit code when using the size estimate option of
340 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
341 submitting the patch.
343 3. Handle EINTR in atomical reads/writes in dump, which was causing
344 dump to fail on some systems. Thanks to Eric Jergensen
345 <eric@dvns.com> for reporting the bug and submitting the patch.
347 4. Handle more than 16 characters for the device names in dumpdates.
348 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
349 tracking down the problem and proposing the solution.
351 5. Fixed a bug in dump which prevented the creation of the
352 dumpdates file when doing a 0-level dump without already
353 having a dumpdates file. Thanks to Patrik Schindler
354 <poc@pocnet.net> for reporting the bug.
356 6. Changed the way dump 'S' flag reports the size estimate
357 from number of blocks into bytes (making it compatible
358 with the Solaris version, and simplifying things for
359 amanda users). Thanks to Jason L Tibbitts III
360 <tibbs@math.uh.edu> for reporting the bug.
362 7. Fixed a compatibility problem in linux/alpha dump tape format.
363 Now the linux/alpha dump are (again) compatible with the
364 other dump formats. But this breaks compatibility with
365 older dumps made on alpha. Thanks to Mike Tibor
366 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
368 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
369 ======================================================================
371 1. Added a '--enable-kerberos' to configure.
373 2. Added a 'S' option to dump which determines the amount of space
374 that is needed to perform the dump without actually doing it, similar
375 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
376 <cermak@ahab.rutgers.edu>.
378 3. Added a 'M' multi-volume option to dump and restore which enables
379 dumping to multiple files (useful when dumping to an ext2
380 partition to make several dump files in order to bypass the 2GB
381 file size limitation). The 'f' argument is treated as a prefix and
382 the output files will be named <prefix>001, <prefix>002 etc. With
383 the 'M' flag, restore automatically selects the right file without
384 asking to enter a new tape each time.
386 4. Fixed a memory leak which was causing dump to grow very big
387 (270MB when dumping a 10GB filesystem...). Thanks to Jason
388 Fearon <jasonf@netrider.org.au> for reporting the bug.
390 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
391 ======================================================================
393 1. Make configure test if the system glob routines support
394 extended syntax (ALTDIRFUNC). If not, use the internal glob
395 routines instead of system ones. Thanks to Bernhard Sadlowski
396 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
397 and helping me resolve this and other minor libc5 compiling
400 2. Fix a problem when dumping a ext2fs with the 'filetype'
401 feature enabled. Thanks to Patrick J. LoPresti
402 <patl@cag.lcs.mit.edu> for reporting the bug and to
403 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
405 3. Made the nodump flag work on directories. A directory which
406 has the nodump flag gets never dumped, regardless of its
409 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
410 which allows dump on an active ext3 filesystem. However, this
411 is a "quick and dirty" patch which enables backup of an ext3
412 filesystem through the ext2 compatibility (by ignoring the
413 NEEDS_RECOVERY bit). The journal file is not recognized and
414 it is dumped (it should not).
416 5. Test the superblock compatibility flags when dumping, in order
417 to be sure that we know how to deal with specific features.
419 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
420 ====================================================================
422 1. Use lchown instead of chown, fixing a possible security problem
423 when restoring symlinks (a malicious user could use this
424 to deliberately corrupt the ownership of important system files).
425 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
426 this and providing the patch.
428 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
429 ====================================================================
431 1. Put dump sources under CVS, added Id tags in all files so
432 one can use 'ident' on binary files.
434 2. Added the dump/restore version in the usage text so one can
435 easily verify the version he is using.
437 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
438 a va_start/va_end problem on linux-ppc (always call va_start
439 va_end in pairs each time we use a vararg function).
441 4. Added again the DT_* constants because old libc does not
442 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
443 for submitting the bug report.
445 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
446 this should enable dumping big (huge) filesystems.
448 6. Added the RSH environment variable in order to be able to
449 use a rsh replacement like ssh when doing remote backups (and
450 bypass the security limitations of rcmd). Now you can do remote
451 backups without being root (or making dump setuid root).
453 7. Modified again the way dumpdates works. For incremental dumps,
454 we need to read dumpdates even if we are not using 'u' option.
455 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
458 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
459 ===================================================================
461 1. Removed the 'k' flag from the restore 'about' text if kerberos
464 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
465 to them (fsetflags takes a char*, setflags an open fd!).
467 3. (f)setflags is called only if the flags aren't empty. If the
468 file is a special file, a warning is printed, because changing
469 flags implies opening the device. Normally, a special file
470 should not have any flag... (Debian bug #29775, patch provided
471 by Abhijit Dasgupta <abhijit@ans.net>).
473 4. Made possible to dump a file system not mentioned in /etc/fstab.
474 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
476 5. Changed the default behaviour to not create dumpdates
477 unless 'u' option is specified. Removed the old "debian-patch"
478 which provided the same thing. (Debian bug #38136, #33818).
480 6. Removed all those dump*announce, since they were getting old...
482 7. Added warning messages if dumpdates does not exist and
483 when an inferior level dump does not exist (except for a level 0
486 8. Debugged the glob calls in interactive mode: restore used a
487 dirent struct which was different from the /usr/include/dirent.h
488 one (this used to work, is it a glibc2 change?), so none of the
489 compat glob (which used /usr/include/dirent.h) or the system glob
490 worked. Restore use now the system dirent (and the system
491 DT_* constants), which are compatible with BSD ones.
493 9. Added a configure flag (--with-dumpdatespath) to specify
494 the location of dumpdates file. By default, it is
497 10. Added the "AUTHOR" and "AVAILABILITY" sections and
498 included the current date/version in man pages.
500 11. Corrected the estimation of remaining time when
501 the operator doesn't change the tapes quickly enough. This
502 was an old bug, I thought I corrected it, and discovered
503 that in fact it was corrected in two different places, so
504 the results canceled each other...
506 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
507 ===================================================================
509 1. Integrated multiple patches from RedHat, Debian and SuSE:
511 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
513 - several fixes in the man pages.
514 - update the default tape device to /dev/st0.
515 - many updates for Linux Alpha (byte ordering, size_t etc).
517 - use environment variable for TMPDIR (instead of /tmp).
518 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
519 - workaround egcs bug (RedHat bugs #4281 and #2989).
520 - wire $(OPT) throughout Makefile's.
522 2. Upgrade the dump revision to 1, making possible to dump filesystems
523 made with e2fsprogs-1.15 or newer. Nothing seems to break...
525 3. Fix some compile warnings, prototype all functions.
527 4. Use glibc err/glob instead of internal compatibility
528 routines (only if available).
530 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
531 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
533 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
534 ======================================================================
536 1. Integrated the changes from FreeBSD-3.1-RELEASE
537 (mostly bug fixes, buffer overruns, dump has now an "automatic
538 tape length calculation" flag, dump/restore can use kerberos now
539 (this is NOT tested), use environment variables for TAPE and
542 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
544 3. Corrected a bug in restore when using 'C' option with multi-volumes
545 tapes (files splited accros two tapes give "size changed" errors
548 4. Corrected the long standing bug when dumping multiple tapes.
549 This works for me, needs further testing.
551 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
552 ====================================================================
554 1. Dump now runs correctly on kernels 2.1.x
555 Fix made by Gerald Peters <gapeters@worldnet.att.net>
557 Changes between versions 0.4b2 and 0.4b3
558 ========================================
560 1. Use realpath() if available
564 Changes between versions 0.4b1 and 0.4b2
565 ========================================
567 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
570 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
572 3. Fixed configure.in to correctly handle --enable-rmt
574 Changes between versions 0.3 and 0.4b1
575 ======================================
577 1. Integrated the changes from 4.4BSD-Lite2
579 2. Integrated the patches from Debian and Red Hat
581 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
583 4. Changed dump to use the Ext2fs library to get block addresses. This
584 should solve the endianness problem on SparcLinux.
586 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
587 distribution's one) to use autoconf
589 6. Fixed a few minor bugs
591 Changes between versions 0.2e and 0.2f
592 ======================================
594 1. Added the creation of named pipes (fifos) in restore.
596 2. Added the -N flag in the restore manual page.
598 3. Added the file kernel.patch which contains the llseek() optimization
599 patch for 1.2.x kernels.
601 4. Fixed a bug in the restoration of symbolic links: owner and group were
604 5. Integrated some changes from FreeBSD 2.2.
606 6. Added a call to ftruncate() after restoring each file to restore
607 correctly files ending by a hole.
609 Changes between versions 0.2d and 0.2e
610 ======================================
612 1. Fixed a bug in the "set owner/mode" process. Every file was restored
613 with owner = root (0) and group = root/wheel/whatever (0).
615 Changes between versions 0.2c and 0.2d
616 ======================================
618 1. Dump is now able to backup 2GB+ filesystems.
620 2. Dump and restore can now be linked as static binaries.
622 Changes between versions 0.2b and 0.2c
623 ======================================
625 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
627 Changes between versions 0.2a and 0.2b
628 ======================================
630 1. Really fixed the bug that I should have corrected in 0.2a.
632 2. Enabled optimization again.
634 Changes between versions 0.2 and 0.2a
635 =====================================
637 1. Disabled the optimization during compilation.
639 Changes between versions 0.1 and 0.2
640 ====================================
642 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
643 the fs_type field (actually, I modified the file fstab.c to make it
644 use the mntent functions).
646 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
647 made by dump should be readable by the BSD restore and backups made
648 by the BSD dump should be readable by restore. Unfortunately, this
649 means that the dump format has changed between version 0.1 and version
652 3. Dump is now able to backup a subtree, it is no longer limited to whole
653 filesystems like the BSD version.
655 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
658 Changes between versions 0.0 and 0.1
659 ====================================
661 1. Now create links rdump and rrestore during the `make install' step.
663 2. Linux port specific bugs added to the manual pages
665 3. Incorrect estimation of the number of tapes blocks fixed when doing
668 4. Better ls-like format in restore in interactive mode.
