The Test Failover Process
Use the Failover Test operation to test that the virtual machines are correctly replicated at the recovery site during recovery.
During the test, any changes to the protected virtual machines at the protected site are sent to the recovery site and new checkpoints continue to be generated, since replication of the protected machines continues throughout the test. You can also add your own checkpoints during the test period. You can initiate a failover during a test, as described in Initiating Failover Live During a Test.
The Failover Test operation has the following basic steps:
|
•
|
The test virtual machine instances are created at the remote site and configured to the checkpoint specified for the recovery. |
|
•
|
The new instances are powered on, making them available to the user. If applicable, the boot order defined in the VPG settings is used to power on the machines. |
|
•
|
Testing. The virtual machines in the VPG are created as instances in a sandbox and powered on for testing. |
|
•
|
The instances in AWS are powered off and removed from the inventory. |
|
•
|
The following tag is added to the checkpoint specified for the test: Tested at startDateAndTimeOfTest. |
The updated checkpoint can be used to identify the point-in-time to restore the virtual machines in the VPG during a failover.
Testing that recovery is accomplished successfully should be done periodically so that you can verify that a failover will work. Zerto also recommends testing all the VPGs being recovered to the same cluster together.
When configuring a VPG, specify the period between tests for that VPG in the Test Reminder field in the REPLICATION step of the Create VPG wizard.
