Tweaked my backup scripts a bit, the emails it sends when it's done actually has basic info in it. Always keep an eye to make sure the drives don't fill then it means I have to tweak the backup job to spread it on more drives. I need to start buying more larger drives though, it's kind of a pain splitting it on smaller drives. I've thought of doing backup tapes and finding a way to just span across multiple tapes but everything I read seems to indicate they are a pita to deal with. Dirty heads etc.
I basically just use hard drives as tapes.
