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).
Understanding failover and failback
AppAssure supports failover and failback in replicated environments, in case of a severe outage in which
the source core and agents fail. Failover refers to switching to a redundant or standby target (AppAssure
Core) upon system failure or abnormal termination of a source core and associated agents. The main
goal of failover is to launch a new agent identical to the failed agent. The secondary goal is to switch the
target core into a new mode so that the target core protects the failover agent in the same way as the
source core protected the initial agent before the failure. The target core can recover instances from
replicated agents and immediately commence protection on the failed-over machines.
Failback is the process of restoring an agent and core back to their original states (before failure). The
primary goal of failback is to restore the agent (in most cases, this is a new machine replacing a failed
agent) to a state identical to the latest state of the new, temporary agent. When restored, it is protected
by a restored source core. Replication is also restored, and the target core acts as a replication target
again.
Performing Failover
When you encounter a disaster situation in which your source core and associated agents have failed,
you can enable failover in AppAssure 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.
Description
Removes the source core from replication but retains the replicated recovery
points.
Removes the source core from replication and deletes all replicated recovery
points received from that machine.
