Star is a very fast, POSIX-compliant tar archiver, maintained for more than 30 years.
It saves many files together into a single tape or
disk archive, and can restore individual files
from the archive. It includes command line
interfaces for the "tar", "Sun-Tar", "cpio",
"pax", and "gnutar" command-line syntax. It
includes a FIFO for speed, a pattern matcher,
multi-volume support, the ability to archive
sparse files and ACLs, the ability to archive
extended file flags, 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 and incremental backups.
It includes the only known platform independent
"rmt" server program.
