Basically title. Is it common to use some kind of RAID for backing up other RAIDs or do people just go with single drives?

Yep, all RAID has the same kinds of issues - largely sensitivity to X number of drive failures. Which is part of why we see RAID 6 (double parity), Mirroring, RAID 1-0, etc, all as mechanisms to provide compensation for disk failure within the RAID.

In the SMB, RAID 10 seems to be the favorite approach today for NAS/Virtualization hosts (ESX, etc), with backup going to a cloud provider such as iland or barracuda.
