tar

Star saves many files together into a single tape or disk archive, and can restore individual files from the archive.

It includes a FIFO for speed, a pattern matcher, multivolume support, the ability to archive sparse files, automatic archive format detection, automatic byte order recognition, automatic archive compression/decompression, remote archives and special features that allow star to be used for full backups.

S tar also includes `rmt, a truly portable version of the remote tape server that supports remote operation between different OS and machine architectures (hides even Linux oddities) and a portable `mt tape drive control program that is able to use the

The RMT program if 100% compatible with Suns extensions for inter-platform operability support (MT status codes) and with GNU extensions for inter-platform open() nteroperability. In addition, it includes my enhancements that hide Linux MT-ioctl non compliances with other UNIX platforms.

Star is the fastest known implementation of a tar archiver. Star is even faster than ufsdump in nearly all cases.

Star development started 1982, the first complete implementation has been done in 1985. I never did my backups with other tools than star.

Here are some key features of "S tar":

· fifo

keeps the tape streaming. This gives you faster backups than you can achieve with ufsdump, if the size of the filesystem is > 1 GByte.

· remote tape support

a fast RMT implementation that has no probems to saturate a 100 Mb/s network.

· accurate sparse files

star is able to reproduce holes in sparse files accurately if the OS includes the needed support functions. This is currently true for Solaris-2.3 to Solaris-2.5.1

· pattern matcher

for a convenient user interface (see manual page for more details). 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 limitation 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)
With POSIX.1-2001 the times are in nanosecond granularity.
Star may reset access time after doing backup. On Solaris this can be done without changing the ctime.

· 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 repairing 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 transparently reads them the right way

· automatic format detect

star automatically detects several common archive formats and adopts to them. Supported archive types are: Old tar, gnu tar, ansi tar, star, POSIX.1-2001 PAX, Suns Solaris tar.

· automatic compression detect

star automatically detects whether the archive is compressed. If it has been compressed
with a compression program that is compatible to decompression with "gzip" or "bzip2", star automatically activates decompression.

· fully ansi compatible

Star is fully ANSI/Posix 1003.1 compatible. See README.otherbugs for a complete description of bugs found in other tar implementations. Star is the first tar implementation that supports POSIX.1-2001.

· support for ACLs and file flags

star supports Access Control Lists and extened file flags (as found on FreeBSD and Linux). Support to archive and restore other file properties may easily added.

· support for all inode metadata

star supports to put all inode metadata on the archive. This allows star to perform true incremental dumps.

· sophisticated error control

allows to tell star which error types should be ignored for wich file name pattern.
This allows to write backup scripts that give no error messages for all problems that are tolerable (e.g. growing log files).

· ed like pattern substitutuions

star supports automated pattern rule based file name substitution as documented for pax.

· fast built in -copy mode

allows to make fast and accurate copies and directory tree comparisons.
star supports automated pattern rule based file name substitution as documented for pax.

· True incremental dump/restore features

star is the first TAR based backup system that has been verified to handle typical file system changes correctly.

Whats New in This Release:

· In case of incremental dumps, star is now sure to write at least the directory "." to avoid empty dumps.
· "star -xpU -restore -force-restore" may be called to force restoring the next level dump.

GNU tar program provides the ability to create tar archives, as well as various other kinds of manipulation. For example, you can use Tar on previously created archives to extract files, to store additional files, or to update or list files which were already stored.

Initially, tar archives were used to store files conveniently on magnetic tape. The name "Tar" comes from this use; it stands for tape archiver. Despite the utilitys name, Tar can direct its output to available devices, files, or other programs (using pipes), it can even access remote devices or files (as archives).

GUI Tar is a wrapper application which acts as the front end to the tar, gzip, and bzip2 UNIX utilities.

The operating system itself handles the complicated work, while GUI Tar provides a pleasant and easy method to interact with these system tools.

GUI Tar is a tool divided into two sections: Extractor and Compressor.

Whats New in This Release:

· Added support for 7-zip (.7z), Bzipped tar archives (.tbz), and UNIX compressed files (.Z).
· Now available as a Universal Binary for both Intel and PPC Macs.
· Updated Help system.
· Full support for zip and bzip2 on earlier versions of Mac OS X.
· New icons for 7z, bzip2, and tbz.

Kung-Tar is a GUI front-end for gnutar. It allows for easily adding several files from different locations to the tar archive.

It has been developed for personal use, but is released with source code since it may be useful to others as well.

Dont expect much from it, though, since its just an AppleScript Studio utility based on the "Archive Maker" example from Apple itself. More details and explanation is in the Readme file.

Whats New in This Release:

· Recompiled for MacOS 10.2.3 with the December 2002 Developer Tools.

In the "old days" of UNIX, compressing/uncompressing and archiving/unarchiving files involved cryptic commands such as tar -xvf somefile.tar.

However, since those days, the masses have come to use computers, and they expect an easy to use system with graphical elements and interaction.

The days of the command-line interface are distant, and expecting the average user to resort to those older methods is normally out of the question. This is where Untar steps in.

Untar is a wrapper application which acts as the front end to a variety of UNIX utilities, such as tar, gzip, bzip2, rar, and zip.

Untar is able to uncompress files in .tar, .tar.gz, .tgz, .tar.z, .z, .gz, .svgz .Z, .tar.Z, .taz, .tar.bz, .tar.bz2, .tbz, .tbz2, .bz, .bz2, .rar, and .zip formats. Source code and project are included.

The Archive::TarGzip module provides tar subroutine to archive a list of files in an archive file in the tar format. The archive file may be optionally compressed using the gzip compression routines. The Archive::TarGzip module also provides a untar subroutine that can extract the files from the tar or tar/gzip archive files. The tar and untar top level subroutines use methods from the Archive::TarGzip class.

The Archive::TarGzip class has many similarities to the very mature Archive::Tar class being at least three years older. The newer Archive::TarGzip relied very heavy on the work of the author of the Archive::Tar and in many instance the Archive::Tar is a better solution.

Altough the underlying tar file format is the same and similar code is used to access the data in the underlying tar files, the interace bewteen the two are completely different. The Archive::TarGzip is built on a Tie File Handle type interface. The nthe Archive::TarGzip provide means to access individual files within the archive file without bringing the entire archive file into memory. When the gzip compression option is active, the compression is performed on the fly without creating an intermediate uncompressed tar file.

Zipper is a free and animated utility for zipping and unzipping files.

Drag files and/or folders onto the Widget and it will compress them into an intelligently named archive, or drop archive files and it will unzip them into folders.

Now supports the following file formats :-
Compression: ZIP, 7ZIP, TAR/GZIP and TAR/BZIP2.
Decompression: ZIP, 7ZIP, TAR/GZIP, TAR/BZIP2, Z, RAR, CAB, ARJ, LZH, CHM, HXS, CPIO, RPM and DEB, plus zipped Widgets and self-extracting executables.
