GNU tar is distributed along with the scripts
which the Free Software Foundation uses for performing backups. There
is no corresponding scripts available yet for doing restoration of
files. Even if there is a good chance those scripts may be satisfying
to you, they are not the only scripts or methods available for doing
backups and restore. You may well create your own, or use more
sophisticated packages dedicated to that purpose.

Automatic Network Disk Archiver), a backup system developed by James
da Silva [email protected] and available on many Unix systems.
This is free software, and it is available at these places:
This chapter documents both the provided shell scripts and tar

To back up a file system means to create archives that contain
all the files in that file system. Those archives can then be used to
restore any or all of those files (for instance if a disk crashes or a
file is accidentally deleted). File system backups are also
called dumps.
