We have been using TapeWare for almost 2 years on an SME Server, and have 
found it to be quite good.  The Windows clients talks quite happily to the 
Linux server.  See http://www.tapeware.com.

That being said, I have almost finished putting together an 'incremental 
snapshot rsync backup' which backs up to another PC running SME.  A base 
level PC with a 80Gig drive is probably less than a tape drive.  Or you can 
even use that old P200 sitting in the corner.  We will also be using this to 
do automated offsite backups over the net.

With a bit of trickery with rsync, hardlinks and samba, you can have 
'snapshot' backups that (except for the first copy) only take up the 
harddrive space of the differences.  eg, the first backup might be 10Gig. 
Each days backup after that is only 100MB, but it looks like you have a 
complete copy of the all files for each day.  The files are shared via samba, 
so users just go to 
//backup/files/snapshots/2002-11-17-13.15/ibays/files/some.file.doc and 
restore their file.  They don't even have to talk to the sysadmin.  :-)

The idea came from Mike Rubel's 'Easy Automated Snapshot-Style Backups with 
Linux and Rsync'.  Unfortunately Mike's site seems to be down.  (Normally 
http://www.mikerubel.org/computers/rsync_snapshots/.) See the Google cache -

You can also look at rsback.  (http://www.pollux.franken.de/hjb/rsback/)

I could probably post my rsync backup script if there is interest, as it is 
designed with SME in mind.  I'd need to clear that with work though.  The 
script is also a little 'rough and ready' at the moment.
