Can I take this opportunity to plug "dirvish" again?  When I ran the
Emporium, all my data were backed up to tape every night, but once I
dropped back to being just a home user I found that backups happened
once a week if I was lucky.  It's just too much hassle to find the time
to do it.

Dirvish takes all the pain out of it.  Once you've set it up it can
happen as a cron job and it gives you multiple (apparently) complete
snapshots of your data going back as far as you like.  In a multi-user
environment you can even make them available as a shared drive and users
can then retrieve their own files which they deleted a week ago last
Thursday.

Because I'm very power-conscious, my always-on server is a Thecus N2100
with just a single HDD in it.  The backup server has two drives in a
RAID1 configuration and wakes up each night just for half an hour or so
to do the backups.  Because of the extreme cleverness of dirvish and
rsync it can even do a complete backup of my remote virtual server in
less than 5 minutes per night.

Highly recommended.
