been released
Star is the fastest tar archiver for UNIX
Star has many improvements compared to other tar imlementations
(including gnu tar). See below for a short description of the
highlight of star.
Star is located on:
ftp://ftp.fokus.gmd.de/pub/unix/star
Changes since star-1.3:
- Fixed a bug introduced a few days before releasing 1.3
that caused star -atime not to work on Solaris.
Star now again is able to do archiving without modifying
times on Solaris if the user us root.

-------------------------------------------------------------
Star is the fastest known implementation of a tar archiver. Star
is able to make backups with more than 12MB/s if the disk and
tape drive support such a speed. This is more than double the
speed that ufsdump will get. Ampex got 13.5 MB/s with their new
DLT tape drive. Ufsdump got a maximum speed of about 6MB/s with
the same hardware.
tails). To archive/extract a
subset of files.
sophisticated diff - user tailorable interface for
comparing tar archives against
file trees This is one of the
most interesting parts of the
star implementation.
no namelen limitation - Pathnames up to 1024 Bytes may
be archived. (The same limita-
tion applies to linknames) This
limit may be expanded in future
without changing the method to record long names.
deals with all 3 times - stores/restores all 3 times of
a file (even creation time)
may reset access time after do-
ing backup
does not clobber files - more recent copies on disk will
not be clobbered from tape
This may be the main advantage
over other tar implementations.
This allows automatically re-
pairing of corruptions after a
crash & fsck (Check for differences
after doing this with the diff
option).
automatic byte swap - star automatically detects
swapped archives and transpar-
ently reads them the right way
automatic format detect - star automatically detects sev-
eral common archive formats and
adopts to them. Supported ar-
chive types are: Old tar, gnu
tar, ansi tar, star.
fully ansi compatible - Star is fully ANSI/Posix 1003.1
compatible. See README.other-
bugs for a complete description
of bugs found in other tar implementations.
Have a look at the manual page, it is included in the distribu-
tion.
