Hint: If you still have common snapshot / backup pairs (i.e. both
"snapshot_subvol" and "target_subvol" are listed) consider sending the

This allows btrbk to continue using the parent subvolume for
incremental backups later.
If everything went fine, nuke the broken subvolume: If everything went fine, nuke the broken subvolume:
