Hello Ronald and Ross. Just a note on other backup solutions...If you do
decide to to commercial I would recommend you take a look at IBM's Tivoli
(aka TSM) backup system if you are looking at large libraries and lots of
data. It is a very impressive system with a completely different stategy
than other backup solutions I've seen. 

That said, Amanda comes the closest so far to bridging the gap (commercial
or GPL). Amanda is a great backup solution, but if I wanted to go commercial
I'd definitely look at TSM. We had it at my old job and it was fantastic. I
won't go into a detailed description unless others would like to read it. If
you want to know more about the comparisons I will answer privately.

Regards,
Gordon
