Disaster Recovery Administration Options
Use Storage Manager to prepare for DR, activate DR, and restore failed volumes. To make sure that a site outage does not
prevent you from accessing Storage Manager to perform DR operations, you can optionally install a remote Data Collector at a
DR site.
A remote Data Collector provides access to Storage Manager DR options when the primary Data Collector is unavailable. In the
event that the primary Data Collector is unavailable, use a locally installed Client to connect to the remote Data Collector.

Preparing for Disaster Recovery
Prepare for DR by saving restore points, predefining DR settings, and testing those settings.
Perform these tasks to implement a DR plan:

Saving and Validating Restore Points
A restore point includes information about a replication or Live Volume, including the source and destination volumes, source and
destination Storage Centers, and the QoS definitions used. If a Storage Center goes down, this information becomes the basis
for restoring the replication or Live Volume.
A restore point for a Live Volume that manages a replication does not contain information about the managed replication.
If DR is activated for the Live Volume using the Preserve Live Volume option, the managed replication continues to
operate and follows the DR-activated volume.
If DR is activated for the Live Volume without using the Preserve Live Volume option, the managed replication is
removed and must be re-created manually.
A restore point for a replication that is managed by a Live Volume does not contain information about the Live Volume. If DR
is activated for the managed replication, the Live Volume must be re-created manually.
Save Replication Restore Points for One or More Storage Centers
Save replication restore points after creating replications or Live Volumes. Storage Manager automatically saves restore points
for replications and Live Volumes.
Steps
1. Click the Replications & Live Volumes view.
2. In the Actions pane, click Save Restore Points. The Save Restore Points dialog box opens.
3. Select the check boxes for Storage Centers for which you want to save restore points, then click OK.
Set a Schedule for Automatically Saving and Validating Restore Points
Set a schedule for automatically saving and validating restore points to make sure that good restore points are always available
to perform Disaster Recovery.
Steps
1. In the top pane of the Storage Manager Client, click Edit Data Collector Settings. The Edit Data Collector Settings
dialog box opens.
2. Click the Schedules tab.
3. Select the Automatically save and validate restore points check box.
