Brief recap: I'm currently using BorgBackup, which among other things
does compression and deduplication. I'm looking at the pros and cons of
changing to Btrfs for backup (I already use it as my main fs). The
backup drives are currently ext4 so would need to be converted.
Now read on.

Borg is awesome.[1]
Any backup you use is better than none. So I'm not going to sugg

It's not obvious that 'btrfs dev add' implies a few things:
- mkfs. It will write Btrfs super blocks on this devi

Yeah I'm pretty conservative when it comes to breaking a raid apart
because it is introducing risk by reducing redundancy. I'd say it's
better to get a 3rd drive. But, wie du willst.

I have 2 disks for the data which I want to be mounted in raid1 (software).
I formated the two disks using btrfs
(mkfs.btrfs -m raid1 -d raid1 /dev/sda /dev/sdb)
It works but, up to now, I can't see the a
