I want to set up append-only backups with ZFS, like https://ruderich.org/simon/notes/append-only-backups-with-restic-and-rclone.
However, this part of zfs-receive.8 makes it sound like a compromised sender could cause snapshots to be deleted on the recipient.
Does ZFS replication unavoidably trust the sender?
