Maybe try a full path instead?
Sorry about the delay.
I imagine that is a bug since it is putting the backups inside and outside that volume. Trying with the full path gives me errors since /btrfs_pool is already at / and /btrfs_pool/btrbk_snapshots will point to a folder inside that sub-volume.

My system is using a /home and /root btrfs subvolumes structure. I mount subvolid=5 in /btrbk_pool for the snapshots.

Making some changes to the configuration seems to solve it (I think). At least the dry run seems to be correct:

It actually did not solved. If really had read my own post, the only thing that happened was the renaming of the snapshot.
