Performing failover on the target Core

When you encounter a disaster situation in which your source core and associated protected machines
have failed, you can enable failover 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 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.
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 is displayed on the
Machines tab under Protected Machines and on the Replication tab under Incoming Replication.
10. Force multiple snapshots, and verify they complete correctly.

Performing failback

After you repair or replace the failed original source core and protected machines, you need to move the
data from your failed-over machines to restore the source machines.
To perform failback:
1. Navigate to the Core Console on the target core, and click the Replication tab.
2. Under Incoming Replication, select the failover agent and expand the details.
3. On the Actions menu, click Failback.
The Failback Warnings dialog box opens to describe the steps you need to follow before you click
the Start Failback button.
4. Click Cancel.
5. If the failed-over machine is running Microsoft SQL Server or Microsoft Exchange Server, stop those
services.
6. In the Core Console for the target core, click the Tools tab.
7. Create an archive of the failed-over agent and output it to disk or a network share location.
8. After you create the archive, navigate to the Core Console on the newly repaired source core, and
click the Tools tab.
