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.
