I=E2=80=99ve been using ZFS in conjunction with SAMBA to perform Apple = Time Machine backuos. It works like a charm. But I might need to move the dataset to another machine or to a newly = created filesystem with larger drives. I know TM somehow fingerprints the backup filesystem and is able to = detect when it=E2=80=99s moved to another disk. I wonder if that=E2=80=99s the case in my instance?=20 If I can zfs send and receive it, creating a identical filesystem down = to the inode level. I would think that moving the TM backup filesystem=20= would work. Any similar experience out there?
