!!! Advice <big>__''Back up your data!!!''__</big> Home user:: Write or acquire a script that copies it off onto another machine. Enterprise server:: Buy a tape drive and consider using a good commercial backup program or writing some ''really good'' scripts. (P.S. __''Back up your data!''__) Otherwise you might end up like [this guy | http://www.wlug.org.nz/archive/sounds/canonhelpdesk.mp3] (warning: contains bad words). !!! Tools If you are looking for commercial dedicated backup tools, take a look at [Arkeia] and BackupExec. For homegrown solutions, you can use tar(1) or rsync(1). The latter is particularly interesting as it can synch directory trees with minimal I/O. To copy to another machine/partition etc you can do <tt>rsync -av --rsh="ssh" sourcedir destdir</tt>. Other options you might like to consider on rsync(1) command line are <tt>-l</tt> which keeps symlinks intact, <tt>-z</tt> which compresses the data (useful over slow links), and <tt>--delete</tt> which deletes files which exist on the destination but not the source (use with caution!!) rsync(1) has also been used as the basis for a number of [Free] tools, such as the excellent [rsnapshot|http://www.rsnapshot.org/], which lets you keep multiple backups at only slightly more space usage than a single day by keeping only one copy of files unchanged across backups. Another rsync(1)-based tool is rdiff-backup(1), a [Python] program based on rdiff(1). !!!
