66 | Working with the AppAssure 5 Core
Performing Failover on the Target Core
When you encounter a disaster situation in which your source core and associated
agents have failed, you can enable failover in AppAssure 5 to switch protection to
your identical failover (target) core. The target core becomes the only core
protecting the data in your environment, and you then launch a new agent to
temporarily replace the failed agent.
To perform failover on the target core
1. Navigate to the AppAssure 5 Core Console on the target core, and click the
Replication tab.
2. Under Incoming Replication, select the source core, and then expand the details
under the individual agent.
3. On the Actions menu for that core, click Failover. The status in this table for this
machine changes to Failover.
4. Click the Machines tab, and then select the machine that has the associated
AppAssure agent with recovery points.
5. Export the backup recovery point information on that agent to a virtual machine.
For more information, see “Exporting Backup Information for your Windows
Machine to a Virtual Machine” on page 144.
6. Shut down the machine that has the AppAssure agent.
7. Start the virtual machine that now includes the exported backup information. You
need to wait for the device driver software to be installed.
8. Reboot the virtual machine and wait for the agent service to start.
9. Go back to the Core Console for the target core and verify that the new agent
appears on the Machines tab under Protected Machines and on the Replication
tab under Incoming Replication.
10. Force multiple snapshots, and verify they complete correctly. For more
information, see “Forcing a Snapshot” on page 141.
11. You can now proceed with performing failback. See the following section,
“Performing Failback” on page 66.
Performing Failback
After you repair or replace the failed original source core and agents, you need to
move the data from your failed-over machines to restore the source machines.
To perform failback
1. Navigate to the AppAssure 5 Core Console on the target core, and click the
Replication tab.
2. Under Incoming Replication, select the failover agent and expand the details.
