This feature allows choosing only those virtual machine (VM) disks you want to back up, and thus to reduce the protected space.
In the Management Console of the cloud failover appliance:
Go to Clients › Edit.
Select a VM, for which you want to configure the selective disk backup.
In the VM Backup group, select Specific Disks, and then click Edit ().
Select the disks you want to back up, and then click OK.
Click Apply to save changes, and then click Activate configuration so the changes take effect.
If you add a disk to a VM after you configured the selective disk backup, the new disk will not be backed up automatically. You have to select it for backup following the above procedure.
If you change order of the VM disks after you configured the selective disk backup, you have to select the disks again.
