I did this before with Bareos/Bacula. I've since decided that product is a bit too black box for my liking. It always did what I asked of it, but the database would crash here and there and that freaked me out a bit. On to something new, and BackupPC was surprising better than I thought it would be. Admittedly it doesn't have an agent in the traditional sense which I don't like, but I was still able to achieve the needed goals.
