Just after I posted, I started thinking about rsync.  I hadn't known  
about rsync's hard link feature.

So once I saw that, the trail did lead me to rsnapshot.  The only  
thing I don't like about it is the security hole it demands of remote  
machines to be able to back up to them.

I'd be happy with that.

I can also take a DB snapshot before running the dump.

Bacula does look impressive.  I'll probably get there some day.  If I  
can deal with the security issue for the remote back-up this will be a  
perfect solution.  If I can't I won't do remote back-up on the machine  
that is awkward to reach, I'll just have to re-arrange things.

Thanks.
