I would also add - when this is discussed in the forums -snapshot/replication is mentioned as a superior alternative (which it can be). But sometimes a folder inside a dataset is what needs to be copied and zfs snapshot/replication cannot do that level from the GUI.
An alternative could also be advice around setting up a cron job using rsync, which can usually achieve this functionality, although setting the flags correctly for the command can be challenging for those not familiar with rsync. Possibly a couple of simple script examples to add to cron?
