Mozy for personal (non-prod) computers. it's like $60/year. Set and forget, my computer was stolen last year, was up and running a day later, most of which was spent purchasing the new computer (Macbook) Prod is more complicated, my company works with several multi-TB data sets (MongoDB) consisting of billions of swiftly changing kilobyte-sized documents. This can't be "backed up" in the traditional sense because it's impossible, barring custom hardware/great expense, to take a consistent snapshot of a multi-TB dataset distributed across dozens of machines. So we do the usual distributed replication across datacenters, put RAID underneath, etc. I worry more about corruption due to application errors than losing a disk for this stuff, though.
