Amanda is a client/server application for making remote backups. While originating from a UNIX environment, it also supports backups of windows machines (via the smbclient utility). Client software for other machines is planned. See the Amanda homepage for details.
The Amanda CDRW-Taper is a drop-in replacement for the taper component of the Amanda backup system. CDRW-Taper makes it possible to dump backups to CD-RW, DVD+RW or DVD-RW instead of tape. CDRW-Taper is licensed under the GNU general public license (version 2) (see COPYING for more information).
