You forgot *the* most important advantage of using send/recv instead of mirroring as the backup method: - Your backup is a pool in its own right that can be imported anywhere Detached mirrors don't get detached in such a way that you could then import them as a separate pool. An option to do that would be excellent though: detach as pool, with pool name and UUID assigned on detach, plus a way to re-attach mirrors detached that way. Other major advantages of this method: - You get to be selective as to which snapshots to backup With a mirror it's all-or-nothing. With send/recv you get to choose what to send to the backup. - You get to be selective as to which snapshots to delete from your backup If you mirror then you lose any snapshots which have been deleted in the primary drive.
