That would be exactly what I would like to use. If I want to sync two
datasets using incremental send, the only way is to remember which
snapshot has to be a base fore next incremental send. Or name snapshots
by a pattern (001, 002, ...) and trust that they won't be renamed and/or
deleted and recreated.
If I'm wrong and I overlooked something, please correct me.
Thank you!
