Why should you use a minimum of two Clones per production LUN when utilizing Clones for backup jobs?

A.
In order to protect against drive failure, EMC recommends two Clones so that they can be configured as a mirrored pair.

B.
When using Clones for backup operations, having a second Clone provides a replica for other offline operations such as running reports, performing data mining, or testing and development operations.

C.
If corruption occurs while one Clone is synchronizing with the production, there is still a gold copy Clone available from which to restore.

D.
Replication Manager requires that one Clone be mounted at all times; therefore a Clone rotation, consisting of AT LEAST two Clones, is required
