Recovering replicated data

Day-to-day replication functionality is maintained on the source core, while only the target core is
capable of completing the functions necessary for disaster recovery.
For disaster recovery, the target core can use the replicated recovery points to recover the protected
agents and core.
You can perform the following recovery options from the target core:
• Mount recovery points.
• Roll back to recovery points.
• Perform a virtual machine (VM) export.
• Perform a bare metal restore (BMR).
• Perform Failback (in the event you have a Failover/Failback replication environment set up).

Roadmap for failover and failback

When you encounter a disaster situation in which your source core and associated protected machine
have failed, you can enable failover in AppAssure to switch protection to your identical failover (target)
core and launch a new (replicated) agent identical to the failed agent. After your source core and agents
have been repaired, you can then perform failback to restore the data from the failed-over core and
agent back to the source core and agent. In AppAssure, failover and failback involve the following
procedures.
• Setting up your environment for failover.
• Perform failover for the target core and associated agent.
• Restore a source core by performing failback.

Setting up an environment for failover

Setting up your environment for failover requires that you have a source and target Core and associated
agent set up for replication. Complete the steps in this procedure to set up replication for failover.
To set up an environment for failover:
1. Install a Core for the source and install a Core for the target.
2. Install an AppAssure Agent to be protected by the source core.
3. Create one repository on the source core and one repository on the target core.

4. Add the agent for protection under the source core.
For more information, see
5. Set up replication from the source to target core and replicate the protected agent with all recovery
points.
