Storage Center DR Preparation and Activation
Activate disaster recovery to restore access to your data in the event of an unplanned disruption.
How Disaster Recovery Works
Disaster recovery (DR) is the process activating a replicated destination volume when the source site fails. When the source site comes
back online, the source volume can be restored based on the volume at the DR site.
The following diagrams illustrate each step in the DR process. Although this example shows a replication, DR can also be used for a Live
Volume.
Step 1: A Volume is Replicated to a DR Site
A volume is protected from disaster by replicating it to a Storage Center located at a DR site.
