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, predening DR settings, and testing those settings.
Perform these tasks to implement a DR plan:
• Saving and Validating Restore Points
• Predening Disaster Recovery Settings for Replications
• Test Activating Disaster Recovery
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 denitions 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 recreated 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 recreated 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.
1 Click the Replications & Live Volumes view.
2 In the Actions pane, click Save Restore Points. The Save Restore Points dialog box appears.
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
DR.
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.
4 From the Frequency drop-down menu, select how often you want restore points to be automatically saved and validated.
