I'd backup to a more reliable filesystem than btrfs. In my experience you will eventually randomly lose data with btrfs. I have lost all trust in it.

Backups are by definition redundant, however, btrfs is still the only Linux filesystem with its featureset. Let me know when ZFS on Linux supports shrinking or cloning file ranges.

"raid" 1/0 and 10 are stable, others are not. Theoretically btrfs can protect against bit-rot where other fs's typically don't.

Theoretically that might be the goal. In my experience data melts away like butter on btrfs.
