The GNU tar program saves many files together in one archive and can restore individual files from that archive. Tar can also be used to add supplemental files to an archive and to update or list files in the archive. Tar includes multivolume support, automatic archive compression/decompression, the ability to perform remote archives, and the ability to perform incremental and full backups. If you want to use tar for remote backups, you also need to install the rmt package on the remote box.
