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

RAID is a choice if you're (generally) trying to maximize storage capacity against cost of drive capacity. It was born out of a lack of drives of sufficient capacity.

Mirroring is useful for protection against hardware failures - it's not a backup.

Follow the 3:3 rule: 3 backups, in 3 different "locations". Locations in quotes because 2 different cloud storage providers count as 2 different locations.

Whether your "local" backup (in your location, at a friend's house, etc) uses RAID depends on your requirements, cost sensitivity, etc.

I have a couple RAID setups only because I always have spare drives around, and it's relatively cheap to build a box to run something like UnRAID or TrueNAS which can take advantage of mixed drive sizes.

My current setup is an old file server with a large drive that is currently replicating to an external drive, a small NAS, and Crashplan.

Not an ideal setup since 2 backups are local (though my NAS is easy to grab and run with, weighs about 10lbs).

Next phase is to move to Storj.io and switch to a proper backup tool like Borg.
