Thinking about it, user-defined properties are probably the right place to store backup status (i.e., whether this snapshot was backed up, when was the last time this dataset was backed up, ...). Might as well add a snapshot ID (monotonically increasing is fine, UUID is better), and use that for rename detection. Deletion of the last backed up snapshot should be discouraged, since recovering from that requires a bigger zfs send to the backup pool.
