Buy a tape drive and consider using a good commercial backup program or writing some ''really good'' scripts.

-An excellent program
for data
backup is [rsnapshot|http://www.rsnapshot.org/], which lets you keep multiple days of
backups at only slightly more space usage than a single day, due to
only keeping
one copy of each file, and copies of any changed
files.
+!!! 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)
.
