be beneficial for replica containers
to support write operations for
restoring data from an archival
target.
For example, data could be
replicated back to the remote site
where the DMA is connected to
allow this data to be restored
directly.
This situation applies to
configurations where data is backed
up from a remote location to a local
container, and then replicated over a
WAN to a replica container that is
backed up to tape.

Workaround/Solution
To leverage deduplication across
the WAN for this scenario:
1
Make sure that the
replication operation has
completed (between source
and target).
2
Delete current replication
relationship, and re-create
replication relationship
(reversing the source and
target roles).
3
Restore data to the original
target container (now the
source).
4
Make sure that the
replication operation has
completed.
5
Delete replication
relationship and re-create
replication relationship
(restoring original source
and target destinations).
Under this scenario, a fraction of
the data to be recovered is sent
across the WAN link. This could
speed up a remote restore
significantly.
