[wellylug] Rotating backups

[Phil Donaldson]

Thanks for the suggestions guys.

I like the sound of the offsite diff backups.
And I'm looking for a backup product - have tried custom scripts and 
they're too much work and hard to support.
I guess I've avoided diff backups so far due to a fear of one piece of 
the diff failing and making my whole backup useless. Do tools like 
Bacula and duplicity prevent this?

To answer Duane's question, for now I need to backup files and a 
database from my file server.

Thanks,
Phil
