> I guess zfs send and similar are better solutions. It depends. I recently built a new zfs pool server and needed to transfer a few TB of data from the old pool to the new pool, but I built the new pool with a larger record size. If I’d used zfs send the files would have retained their existing record size. So rsync it was.
