Actually it does replace backups with replication and/or cloning.

Its not backed up until its at least on an external system, ideally in triplicate off-box, off-site, and cold storage. Cloning and replication makes it easier to backup but is no substitute.
ZFS send/recv to an offsite ZFS box is a backup. Replacing tape systems. It's incremental. Its compressed. It's faster.
That's not a replacement for backups, that's an implementation of backups and only if you send it to an offline disk or remote system.
