Jonathan wrote a cronjob on alog to create two backup files daily: sql dump file
of the text content and compressed tar file of the graphical files.

I just wrote a cronjob, which runs on control100 within CDS, to scp these files
into /data/backup/alog every morning at 05:30. From there they are rsynced to 
the CDS backup disk, and then written to tape.

This backup scheme will be replaced with rsync later because the graphical file will
get very large very quickly.
