Creating Replication and High Availability Cloud Scenarios › Recovery Using an EC2 Failover Replica

Recovery Using an EC2 Failover Replica

If you replicated your on-premises system to an EC2 replica instance and either manual switchover or automatic failover occurred, you can perform data recovery using the EC2 failover replica instance:

• Replicate the Full System EC2 instance to another virtual environment (such as the on-premises Xen/Hyper-V/ESX or to another EC2 RHA appliance)
• Restore individual data sets using the File System replication scenario

The recovery process using an EC2 failover replica is identical to non-cloud scenarios, with some differences. When switchover or failover occurs and a new EC2 failover instance is started, a backward replication scenario with the EC2 appliance as the new master and the on-premises host as the new replica is created:

• An automatic or manual backward scenario is run, which allows only block and file level synchronization.
• It excludes Windows system files from synchronization/replication.
• Lets you change replication directories/registry hives before the backward scenario is run.
• The registry is replicated.

Note: For information about the recovery process, see Recover Lost Data from a Replica.
