Star is a very fast, POSIX-compliant tar archiver. 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. License: Common Development and Distribution License (CDDL) Changes:
star -version now prints the compile options. Star has been prepared for a future POSIX.1-2001 extended tar header keyword, "SCHILY.acl.type". Incremental dump mode now compares whether info->f_mtime >= Newer.tv_sec.
