To support this effort to leverage deduplication across the WAN to allow this

scenario, complete the following:

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. However, there

are some downsides to this type of scenario:

•

If step 1 is not followed correctly, any changes not fully replicated are lost.

•

During steps 2 and 3, any data that is written to the original DR4000

system source container may be lost.

•

During step 4, if the data is not fully replicated back before the switch is

made, it may be lost.

Alternatively, you still could support this effort by completing the following:

1 Create a new container on the target DR4000 system.

2 Set up replication from this container back to the source DR4000 system

container.

3 Set up a new disk storage unit in the DMA and make sure that the DMA is

aware of any new images.

4 Import the old images back into the DMA from the target DR4000 system

(the original source location).

5 Use a new disk storage unit in the DMA, and then restore the data back to

the original client.
