Testing Recovery To Azure
In order to verify that the disaster recovery that you have planned is the one that will be implemented, Zerto recommends testing the recovery of the VPGs defined in the protected site to the recovery site. This section describes how to test VPG recovery to Azure.
The following topics are described in this section:
Note: You cannot perform a failover test while a backup job is running.
Note: When testing recovery from Azure to on-premise sites, the Move operation is used, which assures VM level consistency.
To allow checking before committing or rolling back, specify an amount of time to check the recovered machines, in minutes, before the automatic commit or rollback action is performed. During this time period, check that the new virtual machines are OK and then commit the operation or roll it back. The maximum amount of time you can delay the commit or rollback operation is 1440 minutes, which is 24 hours.
Checking that involves I/O is done on scratch volumes. The longer this period the more scratch volumes are used, until the maximum size is reached, at which point no more checking can be done. The maximum size of all the scratch volumes is determined by the journal size hard limit and cannot be changed. The scratch volumes reside on the storage defined for the journal.
