Suppose I have a fileserver, which may be zpool 10, 14, or 15. No compression, no dedup.
Suppose I have a backupserver. I want to zfs send from the fileserver to the backupserver, and I want the backupserver to receive and store compressed and/or dedup'd. The backupserver can be a more recent version of zpool than the fileserver, but right now, whatever they are, they're the same as each other. And I think it's 10, and I think I have 15 available if I upgrade them. (Obviously I can get accurate details on the exact versions, if it matters.) I have created the destination filesystem with compression. And now my question ... Can I "zfs send" from the fileserver to the backupserver and expect it to be compressed and/or dedup'd upon receive? Does "zfs send" preserve the properties of the originating filesystem? Will the "zfs receive" clobber or ignore the compression / dedup options on the destination filesystem? I'm doing it now. So I guess the question here is sort of academic. ;-) I'll know the answer tomorrow, either way. ;-)
