I use carbonite and my default browser is Chrome. If you dont believe you need reliability, why bother using RAID at all? With plain DVD backups, you at least get archival. They send an appliance over to you that manages all of your scheduling and if you do have a loss on your side you have the option of pulling the data off of the local equipment. Once it is set up properly you don't need to touch it again. Who could expect something like that?
Carbonites one mistake was not backing up their data. I can't tell how good Carbonite is at backing up the files until something goes wrong which makes me nervous. It uses minimal CPU time, and it doesnt use more memory than any other backup tool (or your average antivirus). We dont care if the replicated database isnt backed up, but we sure do want to know when the production database isnt! I am FAR more willing to give credence to a CEO who takes the time to defend what he/shes helping create than someone who main weapons are venom, a thesaurus, and have absolutely no idea how much this company spends on whatever they do and it makes no damn difference either way because if the service works, its affordable, and reliable then why the hell are you not helping these folks.
