2.1 - 2.1.pl1
- minor bugfix in restore script
2.1.pl1 - 2.1.pl2
- Bugfix in configuration programs.
Affects: cartridge handling systems without a special
command to set the cartridge, that therefore
must be set to sequential mode.
Workaround: Comment out the line starting with Setcart-Command
in .../backup/server/lib/backup.conf
2.1.pl2 - 2.1.pl3
- Fix of stupid bug produced while fast-hacking pl2
2.1 - 2.2
- automatic tape labeling and consistency check
- directories can selectively be excluded from backup
- cleverer device access, two stage timeout: 1st stage
sends email to maintainer, 2nd stage exits
- facilities for recovery from hard crash with lost
filename logfiles
- reduced unnecessary tape movements
2.2 - 2.3
- Maintain a lock file to prevent concurrent tape access of
different server processes
- Optional compressing of the filename logfiles
- Client side parameters RootDirectory and BackupHost can
be overridden with command line options of restore
2.3 - 2.4
- Block and character device special files can be saved
- Storing the file contents can be forced independently of
the file type (useful for saving raw partitions or so)
- option -N for the client side program for saving only
files newer than a given one
- small bug fixed concerning zero-length files
2.4 - 2.5
- File contents (see 2.3 - 2.4) can be compressed
- Sockets can be saved
- full_backup, incr_backup and restore are now binaries
- print_errors is a new command
- Weird problem workarounded with I/O-Error on interrupted
backup
- If filename logfiles should be compressed, no uncompressed
files ever appear
- Directory path patterns can be supplied for excluding files
or directories
- Support for a max of 16777215 cartridges with 2147483647
files on each (please consider configuring several backup
servers ;-) )
- Restore can be called with glob-style filename patterns
- For the client side a lockfile is maintained as well, so
several backup or restore programs can't be run simultaneuosly
on one client causing trouble on the logfiles
2.5 - 2.6
- File contents can not only be specified with prefixes /../
or //../, but also by option -r or -R
- Saving files can be limited to device/filesystem
2.6 - 2.6.1
- New client- and serverside parameter EncryptionKeyFile
for the authentication mechanism
- New clientside-parameter VarDirectory for varying files
- Default-configuration files in /etc/buclient.conf and
/etc/buserver.conf
2.6.1 - 2.7
- New clientside parameter CompressBackupedFiles for choosing
compression of files and filename logfiles separately
- Clientside request-queue for asynchronous communication with
the server (hopefully much better performance)
- New serverside command "label_tape" to manually write a label
to the tape actually in the drive
- Default-configuration files can also be (Debian needs)
/etc/afbackup/client.conf and /etc/afbackup/server.conf
- Bug (typo) fixed: Entry for locking file in the server
configuration file has been ignored
- HOWTO-file is maintained now
2.7 - 2.7pl1
- Better connection failure handling. Up to now with DAT data
on tape might be lost on a connection breakdown
2.7 - 2.8
- Normal filesystems can be used for backups instead of tapes,
thus also removable media
- A file with a special name can be placed in any directory
containing names or patterns of files and subdirectories to
be excluded from backup
- Compression attempts can be avoided on already compressed
files by supplying appropriate filename patterns
- Slight further speedup
- Small bug fixed (sometimes a "Connection ... lost" occurs)
2.8 - 2.8plX
- Bugfixes, more logging, more diagnostic messages, more
safety
2.8 - 2.8.1
- Port number can be configured in the configuration file
of the client side
2.8.1 - 2.8.2
- FreeBSD supported
- Wrapper script for mt added: __mt (FreeBSD's mt does not
accept 0 as repeat count)
- Non-GNU-make can be used (under Solaris it's a little
annoying) and is recognized automatically
2.8.2 - 2.8.2.pl1
- Bug ignoring several -m or similar in file list fixed
2.8.2 - 2.9
- Several sets of cartridges can be used on the server side
- Verify is now possible
- restore does not restore the same file several times
from different backups
- memory leak fixed (a quite harmless one, quasi more a
theoretical one, no sole reason for an upgrade)
- Documentation reviewed and lots added, e.g. an INTRO
- An exit command can be configured, usable for reporting
successes and statistics to an administrator
- Ordinary users can restore their own files and directories
2.9 - 2.9.pl1
- With several cartridge sets configured reading over end of
tape of the last cartridge change to the first cartridge
of the same set and not to cartridge 1. This was a bug
2.9 - 2.10
- Byte Sums are no longer of type "long int", now "double"
("long long int" is a portability problem)
- Buffering also on the server side. Especially read
operations (verify, restore) should be much faster now
- Stale lockfiles do not cause another server process or
a highlevel client program to wait. This was a bug
- Several kill-s to the server don't harm, no stale lockfile
is left over (of course not valid for a kill -9)
- Errors are immediately printed before completion of client
programs. print_errors is not really necessary anymore,
anyway i consider it helpful for later diagnostics
- No longer confusing message "Cannot find out number of
lines in ..."
- No longer annoying message "/tmp/xxxxxx: No such file
or directory"
- Safer tape handling (hopefully)
- Strange AIX problem workarounded (EIO at end of media
instead of the documented ENXIO)
- A modified-before- and -after-date may be supplied with
the restore program
- Autodetecting inserted cartridge, if tape is labeled or
had already been used
- Strange wish behaviour (too flat window) workarounded
- Missing feature added: modification time is saved with
file contents i.e. e.g. raw devices
2.10 - 2.11
- Second possibility to save backups in a filesystem
(without the need of symbolic links)
- Output of XXXXXXconfig is piped through more for
convenient configuration from any terminal
2.11 - 2.11.1
- libc-6 (i.e. glibc) - ready (see README: THANKS TO)
2.11.1 - 2.11.2
- Insufficiency of the cartis script fixed: read the number
of cartridge sets from the server configuration file
- (x)clientconfig and (x)serverconfig did not look for config
files in all intended places, documentation incomplete
2.11.2 - 2.11.3
- Minor inconsistencies fixed. Utilities added (yet unused)
2.11.3 - 2.11.4
- Security hole fixed
2.11.4 - 3.0
- Debianized
- Defaults changed somewhat
- Uses autoconfig
- full_backup, incr_backup, restore and verify can override
most of the config file settings by commandline options
- New parameter: Device-probe interval
- New parameter: Skip-files Command
- Documentation reworked (including man-pages)
- restore now takes -C instead of -R, -R is still recognized.
-C is now the changedir-option in conformance with the
other commands (and BTW tar)
- label_tape has new -q option for reading the tape label
- Emergency restore without any input information (-E)
- Emergency restore or only the minimum restore info (-El)
or only tape scanning (restore -En)
- Differential backup with option -a for incr_backup
- Hopefully more speed by use of appropriate TCP-options
- Option to use 128 Bit DES encryption for client-server
authentication (requires Eric Young's libdes)
- cartready indicator file mechanism changed (other way round)
- Logging of the remote host name, if authentication fails
- Possibly conflicting program names prefixed with af
- Bug fixed setting the wrong cartridge for a set, if one set
comprises of cartridge #1 only, what should be avoided anyway
- Senseless settings of maximum number of bytes per tape file
caught and reset to reasonable value
- Year 2039-ready i.e. any length time_t on any architecture
- More appropriate filename handling on recursive extraction
of directories
- Preferred serving of repeated requests from the same client
to avoid race conditions
- Better locking algorithm for client start and server access
- SunOS 4.XYZ supported platform
- Symbolic links are allowed for all programs (full_backup, ...)
- On remote start the output of the remote command is transferred
to the client side, also the exit status corresponds
- Generally better diagnostics for remote start
- Very stubborn problem on HP-UX-9 fixed, maybe the problem was
leading to problems also on other architectures
- New parameter: InitProgram for the client side. StartupInfoProg
is now ran later, when backup succeeded
- In serverside init and exit command %p is replaced with client's
peername
3.0 - 3.0.1
- New flag -w for afclient to check server side streamer state
- differential backup with incr_backup -a did not work yet (!)
(implementation was lost probably due to multiple development
locations and inconsistent code between them, sorry)
3.0.1 - 3.0.2
- New flag -l for afclient to report the location of the server
side for each file (preparation for storage pools)
- docs updated
3.0.2 - 3.0.3
- restore -f was broken in 3.0.1 - 3.0.2
3.0.3 - 3.0.4
- Server side rexec path had wrong default
3.0.4 - 3.1
- Several triples backup-host/backup-port/cartridge-set possible,
all handled transparently to the user
- Server side lock bug fixed (caused minor requests like -q to
hang, had to interrupt with Ctrl-C, bug appeared in 3.0.3)
- Also scripts (e.g. clientconfig) may be arbitrarily symlinked
- Preinstalled config file has now empty encryption file - caused
confusing log message (" ... using compiled-in key")
- Install script supports change of afbackup service name
- Docs adapted
