<H1><A NAME="0560">5.6.0</A></H1>
<IMG SRC="aninew.gif" ALT="New" ALIGN=CENTER> <STRONG>New</STRONG>
<UL>
<LI>New triple buffering system - forks off a child to do its
 writing so should improve backup performance. The tape drive
 won't have to stop so much. You'll really notice this in
 uncompressed backups - performance gains in compressed backups
 depend on your processor speed. If you wish to utilise this,
 your kernel must have SYSV_IPC support.
<LI>Internal compression support. Taper now uses LZRW-3 compression
 code, written by Ross Williams. It has been modified for use
 under Linux by Claus-Justus Heine (the author of zftape) and to both
 people I am eternally grateful (saved me a lot of hassle). The
 internal compression support is a lot faster than gzip, however
 not as efficient - it can produce compressed files that are
 about 30% larger than gzip would have produced. Thus you have
 the option of still using gzip - change using preference
 files, command line options or the preference menu. You can
 mix different compression methods in an archive, but not
 within a volume. Note that the compression option is
 now --compress-type and the preference is COMPRESS_TYPE
<LI>New option - --comp-head-start (preference COMP_HEAD_START). This
 gives the compression program a head start to allow taper to
 continually stream the tape drive on very slow systems. You
 may need to give a value as high as 10 minutes
 so that there is enough compressed programs in the buffer for taper.
<LI>Uncompressing of files in restore is now done in the background.
 This should speed restore operations considerably
<LI>You can now abort backups. Press q or Q during the backup.
</UL>
<IMG SRC="anilight.gif" ALT="Traffic Lights" ALIGN=CENTER> <STRONG>Changes</STRONG>
<UL>
<LI>Changed the backup/mkinfo/restore rate messages - now prints
 the actual tape transfer rate and then the effective tape
 transfer rate. Also changed from K/sec to M/min
<LI>Changed everything from bytes to MB.
<LI>Few changes to the Makefile - separate Makefiles are now
 distributed for different tape drives. Also changes
 to enable easier version upgrades for me
<LI>A further level of logging has been provided - level 4. This
 is very verbose and really shouldn't be used unless debugging.
 I'll need it if you have a bug report
<LI>Disabled ctrl-c - no interruption now. To stop a backup,
 restore or compress operation, press q.
<LI>Added .jpg files in default of files not to compress
<LI>Lots of changes to common.c code to reduce its size and
 place code more appropriately amongst files
<LI>Improved memory usage when compressing in background
<LI>Prints Checksum OK messages in restore/mkinfo in log level 1
<LI>No longer checks if the compressed file is larger than the
 original file using gzip. This situation occurs very rarely, and
 if it does occur, the compressed file is seldom more than a few bytes
 longer than the original file - thus the overhead of checking
 each file is not worth it.
<LI>Mkinfo will update volume counts if they differ
</UL>
<IMG SRC="anibug.gif" ALT="Bug" ALIGN=CENTER> <STRONG>Bug Fixes</STRONG>
<UL>
<LI>Bug in mktape - not closing the tape device --&gt; giving
 resource busy errors
<LI>Mkinfo was not restoring volume counts and volume selections
 properly in a few obscure cases
<LI>Plugged another memory leak - occurred if got a memory allocation
 error while allocating blocks
<LI>Errors if tried to overwrite a regular file. Now the regular
 file is correctly deleted.
<LI>Counts etc.. in restore
<LI>Backup crashed if it couldn't read a directory it needed to -
 now ignores it and doesn't back it up
<LI>When selecting which archive to restore from, wasn't printing
 all the entries on screen correctly
<LI>Seg fault after printing usage
<LI>Errors with the FIFO in backup don't cause the file to be not
 backed up. It now saves the file uncompressed.
<LI>When saving preferences to a command line file, was always saving
 to start_taper despite what you typed in

<LI>In main menu, put Check archive after mkinfo to reflect its
 action
<LI>Exit key from preferences (default F10) can be changed in
 common.h
<LI>No .. entry provided if in root directory for backup/file set
<LI>Enabled support for get block size ioctl of zftape - if you
 are going to use zftape, you must use at least version 1.02
<LI>Can now unselect from the top directory window in backup. If
 the file is indirectly selected, then an error is printed.
 Similarly, can unselect from restore menu.
<LI>Unselecting a file has changed from `d' to `u'.
<LI>Fixed problem with zftape-1.02 and taper interaction. Causing
 multiple "unknown tape data" errors. Downside is that it
 takes longer to identify a tape.
<LI>Fixed problem with zftape-1.02 when using different block sizes
 in different volumes.

<LI>Problem if information messages, etc. were too long for
 message boxes
<LI>Seg fault when trying to load a file set
<LI>Bug in testzero caused a segfault
<LI>Was ignoring all files if the exclusion list was empty. Same

<IMG SRC="aninew.gif" ALT="New" ALIGN=CENTER> <STRONG>New</STRONG>
<UL>
<LI>AT LAST - support for unattended backups. See documentation
 for details on how to do it. New preferences menu for
 unattended preferences.
<LI>Support for the new floppy tape driver, zftape.
<LI>Drives that have leading zeroes do not need a compile time
 option - it is automatically built in. You still, however,
 need to using mktape on tape before you can use them with
 taper.
<LI>Support for fully fixed block reading and writing. All transfers
 to/from the tape drive are in strictly blocksize blocks.
<LI>It is possible to get taper to call MTSETBLK to set the tape
 block size before doing an erase. Define
 SET_BLOCK_SIZE in the Makefile. With the option, the block
 size is also set using an ioctl call after each open (but
 only for zftape).
<LI>Support for quick fast forwarding. Some tape drives are able to
 fast forward a volume while in the middle of a tape. In addition,
 they correctly fast forward if at the end of a volume.
 If your tape drive is one of these, performance can be
 improved up considerably by defining -DFAST_FSF in the
 Makefile. A new program, testfast_fsf will tell you
 if your tape drive is capable of this.
<LI>When selecting entry from on_archive list, prints
 an error message if the file/directory no longer
 exists, as opposed to just ignoring you.
<LI>Using the --version option also prints which options taper
 was compiled with
<LI>When doing a backup, prints the total size of archive.
</UL>
<IMG SRC="anilight.gif" ALT="Traffic Lights" ALIGN=CENTER> <STRONG>Changes</STRONG>
<UL>
<LI>Changed the Makefile option MEMORY to MEMORY_TIGHT
<LI>Changed the output of the log file slightly if an
 error was encountered
<LI>More logging for tape changes
<LI>In incremental backups, if a file needs to be backed up,
 all the relevant directory entries will be backed up
 even if they haven't changed - saves having to get a
 directory entry from one volume and the files from another.

<UL>
<LI>In backup and restore, you can select files & directories
 for backup & restore from the "on_archive" window
 (ie. the top right). Just press 's' and the appropriate
 file will be selected, the same as if you had pressed
 's' in the top left window.
<LI>New option (-A id [--archive-diff]) lets you print a list of files
 that have changed since the last backup was made. The
 list is printed to the screen. id is archive ID to
 compare, -1 means use the archive in the tape drive

<UL>
<LI>In backup, compression of programs in now done in the
 background to speed up execution time
<LI>Memory is now allocated in blocks when required. This
 has the slight overhead of increased memory requirements,
 (maximum extra is 100K) but means that reallocation of memory
 blocks is greatly reduced, reducing system overhead &
 load
<LI>Auto-descend option in restore. If a directory only has
 one directory entry in it, it will automatically descend
 into this directory. Similarly, it will auto-ascend.
<LI>In effect, two versions of taper are available - one is a
 fast, but memory & resource hungry taper. The other is
 much more modest in memory requirements (but still improved
 over earlier tapers - approx 15% memory required than
 5.1.5) but you pay with an increase in load and decrease
 in speed. Define the appropriate option in the Makefile
<LI>If you overwrite an archive, taper will delete the old
 info file
</UL>
<IMG SRC="anilight.gif" ALT="Traffic Lights" ALIGN=CENTER> <STRONG>Changes</STRONG>
<UL>
<LI>Optimised code for calculating directory sizes. Much quicker
 now.
<LI>Optimised code for selecting files to restore. Much quicker.
<LI>Changed the most recent restore handling. For restoration, the
 file on the latest volume is regarded as the most recent.
 This has speeded up the code considerably, the penalty is
 that if a file on an older volume is actually more recent,
 it won't be picked up. This will happen extremely rarely.
<LI>When selecting directories in restore, will now print the
 size of the directory that will be restored taking into
 account most recent restore.
<LI>Tightened up handling of /proc device
<LI>Make common path takes into account volume restriction
 (if any)
<LI>Minor changes in the log file messages printed by restore
<LI>When saving file sets, will create set directory if
 doesn't exist.
<LI>The -d (--print-dir) option now requires the archive_id
 of the archive whose contents you wish to print. A
 -1 will print the directory of the archive currently
 in the tape drive
<LI>Not allowed to change directories when selecting an info
 file
<LI>Does not have to traverse through a whole regular file
 archive now while restoring - will stop when all files
 been restored.
<LI>Few more status boxes etc.. to give user idea of what's
 going on
<LI>Mkinfo will verify checksums. Prints an error to the log
 if it doesn't match

<LI>Minor screen corruption in backup after restoring from
 set
<LI>Not reading all entries in when restoring from file set
<LI>Changing directories inadvertantly after reading in
 file set
<LI>When calculating total selected sizes in restore, was
 including the size of the directory entry, as well
 as the sizes of the files in the directory
<LI>Was not backing up backup device entry in /dev.
<LI>Not a bug, but in backup, was getting file info for a file
 twice - waste of time.
<LI>Not backing up missing directories when found.
<LI>If entry was too long in on_archive window, was not truncating
 properly
<LI>If backup didn't correctly make missing directories,
 restore was stuffing up

<LI>After many requests, memory usage has been dramatically reduced by
 re-organization of the way taper handles files currently on the
 archive. Unfortunately, no-one gets anything for free and this
 memory saving comes about by taper suffering a bit of a
 performance hit. It doesn't affect backing up/restoring - only
 selecting files. It shouldn't make too much of a difference,
 but if you have a large number of files on your archive, you
 may notice the keyboard a bit sluggish. However, your
 memory usage will only be 30% of that in taper 5.1.3.

<IMG SRC="anibug.gif" ALT="Bug" ALIGN=CENTER> <STRONG>Bug Fixes</STRONG>
<UL>
<LI>Not correctly storing missing directories - resulted in problems
 with incorrect file counts. Most common symptom is restore not
 printing all the files on the archive, or funny files in the
 restore screen. The archives written with earlier versions will
 still contain the incorrect file count, however, to overcome
 it, run mkinfo on your old archives, and the info file will
 be fudged to overcome the error. A message will be printed
 in your log file saying that the info file has been fudged.

<IMG SRC="aninew.gif" ALT="New" ALIGN=CENTER> <STRONG>New</STRONG>
<UL>
<LI>Major archive format change - basically, more information was
 added to volume headers to make incremental backups easier.
 This means that archives created under taper 4.x are not
 compatible with 5.0. The volume & archive magic numbers have
 been changed to reflect this.
<LI>Restore even more intelligent with regular file restores -
 doesn't have to traverse the whole archive now. Stops
 when restored all files required
<LI>Info files have been renamed from taper_xxx to taper_info_xxx
 (to allow use of backup sets which will be named taper_set_xxx)
<LI>In restore, you get to select which archive you wish to restore from.
 Taper prints a list of all archives it knows about. The default
 archive selected is the one in the tape drive (or the one
 that pertains to the regular filename given). The tape doesn't
 have to be in the drive to peruse an archive.
<LI>Changes to incremental backup & incremental restore. See TAPER.DOC
 for details
</UL>
<IMG SRC="anilight.gif" ALT="Traffic Lights" ALIGN=CENTER> <STRONG>Changes</STRONG>
<UL>
<LI>In selecting files for a backup, when you move up a directory,
 the cursor points to the directory you were in (like mc)
<LI>If there is no title (archive, volume etc..), rather than printing
 a NULL string, the string &lt;no title&gt; is printed
<LI>In backup & restore, permissions are no longer printed. They were
 wasting too much valuable screen real-estate, and really, are
 not of much use in an archiving system. In restore, the date/time
 the file/directory was backed up is not printed - that information
 can be obtained from the right hand window (volume information)
<LI>Restore now prints details of what's on archive like backup
<LI>Major change to TAPER.DOC to reflect all new features
<LI>Better handling of status reports in restore
