The Failover Operation
Following a disaster, use the Failover operation to recover protected virtual machines to AWS. A failover assumes that connectivity between the sites might be down, and thus the protected virtual machines and disks are not removed, as they are in a planned Move operation.
When you set up a failover you always specify a checkpoint to which you want to recover the virtual machines. When you select a checkpoint – either the last auto-generated checkpoint, an earlier checkpoint, or a user-defined checkpoint – Zerto Virtual Replication makes sure that virtual machines in AWS are recovered to this specified point-in-time. For details, see
“Managing Failover Live to AWS”, on page 159.
Note: To identify the checkpoint to use, you can perform a number of test failovers, each to a different checkpoint.
Failback after the Original Site is Operational
After completing a failover, when the original site is back up and running you can failback the recovered virtual machines back again.
The following diagram shows the positioning of the virtual machines before and after the completion of a Failover operation.
Note: The Failover operation leaves the VPG in a Recovered state.
