Keep in mind that RAID is more about speed of recovery and protects
against the failure mode of total drive failure, which is a fairly
common failure mode.  A hard drive failure on a RAID involves no
unplanned downtime, and a need for some short planned downtime to
replace the drive.

Backup protects against a lot more, but typically results in a
recovery that takes hours, and when the drive goes you're down without
warning.

So, stuff like photos I backup to the cloud, or to offsite media
(generally I favor the cloud for active stuff, and offsite media for
stuff I'm done with).  Ditto for things like /etc, mysql, documents,
email, and other small but important things.

For stuff like MythTV recordings I used to just rely on RAID -
recognizing that there was a very real possibility that I could lose
them all.  Now I also do a backup to a drive that is normally left
unmounted, which isn't great, but since I moved to btrfs I wanted
something on ext4 that had daily rsnapshots.  Again, I'm willing to
risk losing this stuff.
