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.

Recovering a protected virtual machine to AWS requires importing the machine and its associated volumes into EC2. Each machine and volume requires a separate import process. By default, Amazon limits accounts to a specific number of parallel import processes. If you have more machines and volumes than this limit, the process takes longer. The additional machines and volumes are queued and are imported only after an import process is available. If you intend to protect more machines and volumes than can be imported at one time by default, Zerto recommends that you contact AWS Support to increase the ec2‑import-instance/volume limit.
