I like Carbonite too. Every once in a while I go in and make sure it's doing it's "thang". I keep all my clients files on a spare drive and do NOT have Carbonite back that up, rather I do that manually as it's just a layer of security to ease my own paranoia. If you are using any backup system online remember that you are backing up what you have, so let's say you have adware/spyware/malware on there.. guess what.. now it's on your backup AND out there. I have my system maintenance scheduled before my backkup JUST in case. I do full system scan (spyware, virus, etc) and then it runs backup. Just thought I would add that.
