This article serves as a how-to guide for users who want to perform a failback after repairing or replacing the failed original source core and agents.
After you repair or replace the failed original source core and agents (see “Performing Failover/Failback on the Target Core“), you need to move the data from your failed-over machines to restore the source machines.
Complete the steps in this procedure to perform a failback.
To perform a failback
1. Navigate to the AppAssure 5 Core Console on the target core, adn 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 will open up and display the steps necessary to follow before you click the Start Failback function.
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. For more information, see the article titled “How to Create an Archive.”
8. After you create the archive, navigate to the Core Console on the newly repaired source core, and click the Tools tab.
9. Import the archive created in Step 7. For more information, see the article titled “How to Import an Archive.”
10. Go back to the Core Console on the target core, and click the Replication tab.
11. Under Incoming Replication, select the failover agent and expand the details.
12. On the Actions menu, click Failback.
13. In the Failback Warnings dialog box, click Start Failback.
14. Shut down the machine that contains the exported agent that was created during failover.
15. Perform a bare metal restore (BMR) for the source core and agent.
NOTE: When you launch the restore, you will need to use the recovery points that were imported from the target core to the agent on the virtual machine. For more information, see the article titled “How to Launch a Restore from the AppAssure 5 Core”).
16. Wait for the BMR reboot and for the agent service to restart, and then view and record the network connection details of the machine.
17. Navigate to the Core Console on the source core and, on the Machines tab, modify the machine protection settings to add the new network connection details.
18. Navigate to the Core Console on the target core, and delete the agent from the Replication tab.
19. In the Core Console of the source core, set up replication again between the source and target by clicking the Replication tab, and then adding the target core for replication.
