Exporting Replicated Filesystems - Oracle ZFS Storage Appliance Administration Manual

Remote Replication Concepts
If the share containing the clone origin snapshot is not in the same project or if the clone or
■
its origin share have been omitted from project-level replication, replicate the origin share
first and then replicate the clone using project-level or share-level replication.
On the target system, do not destroy the origin of the clone unless you also intend to destroy
■
the clone itself.
To ensure that the origin snapshot is sent to the target, always set the property "Include
snapshots" for the origin's replication action.
Just as a clone and its origin snapshot conserve space on the source appliance, a replicated clone
and its replicated origin snapshot conserve space on the target appliance. If space conservation
on the replication target is less important, the administrator may set the property Include
clone origin as data. When this property is set, and the origin snapshot of a clone is not
replicated in the same update as the clone, the source appliance inserts a copy of the clone
origin's data content into the replica clone. Thus, there is no need to replicate the clone origin
share first, but the copy of the clone origin data consumes additional storage space on the target.
When Include snapshots and Include clone origin as data are both set, the replica clone
contains only the snapshots that are present in the clone on the source. The source appliance
inserts the clone origin data content, not the clone origin snapshots, into the replica clone. This
ensures that the snapshots present in the replica clone match the snapshots present in the clone
on the source.
The property Include clone origin as data does not affect the replication of a clone and
its origin snapshot when they are both replicated in the same update. When replicated together
by the same replication action, the relationship between the clone and its origin snapshot is
preserved and the space sharing benefit is retained on the target.

Exporting Replicated Filesystems

Replicated filesystems can be exported read-only to NAS clients. This can be used to verify
the replicated data or to perform backups or other intensive operations on the replicated data
(offloading such work from the source appliance).
The filesystem's contents always match the most recently received replication snapshot for that
filesystem. This may be newer than the most recently received snapshot for the entire package,
and it may not match the most recent snapshot for other shares in the same package. For details,
