Reverse Protection Specified
When you specify reverse protection, the virtual machines are moved to the recovery site and then protected using the values specified during the move. Data is promoted from the journal to the moved virtual machines and then synchronization with the original site is performed so that the VPG is fully protected. When reverse protection is specified, a Delta Sync is performed. A sync is required since the recovered machines can be updated while data is being promoted.
Reverse Protection for VMs protected in multiple VPGs (One-to-Many)
Zerto enables you to protect virtual machines in a maximum of three VPGs. These VPGs cannot be recovered to the same site.
If Reverse Protection is selected, and the virtual machines are already protected in other VPGs, the following occurs:
■ The vCD vApp are deleted from the protected site.
■ The replication of other VPGs containing these machines is paused.
■ The recovery of all the virtual machines, including the virtual machine removed from the protected site, is possible.
To resume replication do the following:
1. Open the Edit VPG wizard.
2. Select the virtual machine that was previously removed from the protected site.
3. Remove the virtual machine from the VPG.
If the protected VPG contains a vCD vApp, and the vCD vApp is protected in other VPGs, Reverse Protection is selected, the following occurs:
■ The vCD vApp is deleted from the protected site.
■ The checkpoints of the VPG are retained.
■ The deleted vCD vApp can no longer be recovered.
In the event of vCD vApp or if no other virtual machines are left to protect, the entire VPG will be removed.
VPGs enter a state of pause, and paused replication if the following conditions apply:
■ The ZVM on the protected and recovery sites are of version 5.5 and higher.
■ The VRA installed on the recovery site is of version 5.5 and higher.
Protecting virtual machines or a vCD vApp in several VPGs is enabled if:
■ The protected site and the recovery site are of version 5.0 and higher
■ The VRAs installed on these sites are of version 5.0 and higher.
