Do not have faith that the backup you have just written is going to be
readable.  Immediately after taking the backup, read it back and ensure
the data has really been scribbled to your backup media.  DO NOT rely
on a zero return code from your backup command.  I have seen several
occurances when a tape drive has failed to write to the tape but has
"forgotten" to inform the o/s of this fact.  I haven't seen it (yet) on CD
drives, but I guess it could happen.  

Also store you backups offsite.  Take them to work and leave them in
your drawer, or take them to a friends place.
