Its not raid, just a btrfs single on disk (no partition). Contains a single borgbackup repo for an offline backup of all the online borgbackup repo's I have for a 3 times a day backup rota of individual machines/data stores - I get an insane amount of de-duplication that way for a slight decrease in conveniance!
So - are you using btrfs's replication ability to push a backup? Does it just push the changed blocks?
I'm planning to pull a similar stunt - I've got my eye on an 8TB Toshiba N300, which I shall put lvm on, and then (my filesystems are all ext4) do a snapshot and in-place rsync.
Given that my entire dataset is about 2.5TB (including films, photos etc that don't change), again, I've got a massive amount of space to hold backups for ages ...
