I used a DVD+RW as a backup tool.

I have 4 linux servers.  All are mounted to the backup server via NFS to 
one directory.  Each linux box tar and zips its own directories and 
moves them to the mounted NFS directory each night via a cron job.  Then 
twice a week, the DVD burner burns that one directory and deletes the 
files.  This has been going on for over 1 year with no issues.  I used 
to use a DLT tape, but found the DVD medium much more reliable.
