The Failover Operation
Following a disaster, use the Failover operation to recover protected virtual machines to Azure. 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 Azure are recovered to this specified point-in-time. For details, see
“Managing Failover”, on page 166.
Note: To identify the checkpoint to use, you can perform a number of test failovers, each to a different checkpoint.
The following diagram shows the positioning of the virtual machines before and after the completion of a Failover operation.
Before Failover
Failover - Protected Site Down
Failover - Protected Site Up, No Reverse Protection
Note: The Failover operation without reverse protection does not remove the VPG definition but leaves it in a Needs Configuration state.
