Hi,
maybe someone can enlighten me. I am doing btrfs send receive with full
snapshots and incremental updates.
It basically looks like this:
vol-0 and vol-1 are full subvolume image sends.
inc-1 and inc-2 are incremental images with:
# btrfs send -f inc-1 -p vol vol'
# btrfs send -f inc-2 -p

That's because the test shouldn't be in your root in the first place.
The common way of thinking now is to create a btrfs volume with a
structure for holding subvolumes inside of which your system root is a
member. You then mount the system root via -o subvol= and will only
see it and nothing
If you care about the data, create a backup if you haven't already
done so. Then you can try btrfsck, maybe you are in luck!
