Dell EMC Avamar for VMware 19.7 User Guide

Virtual machine power state

When using image restore to restore an entire image or selected drives, the target virtual machine must be powered off.

Restores involving physical RDM disks

When restoring data from a backup taken from a virtual machine with physical RDM disks, you cannot restore that data to a new virtual machine.

Nested container limitations

When restoring a VMware container that contains other containers (that is, a nested container structure), Avamar only restores the top-level of the hierarchy. Consider the following example nested vApp structure:

When vApp-1 is backed up to Avamar, the vApp backup image will only contain virtual machine backup images for vm-1 and vm-2. When vApp-1 backup is restored, only vm-1 and vm-2 will be present.

Two interim solutions exist for this limitation:

• Flatten the container structure.

  For example, move vm-3 under vApp-1. Then all three virtual machines will be backed up when vApp-1 is backed up.

• Add both vApp-1 and vApp-2 to Avamar as separate container entities so that they can be backed up separately.

  When restoring, restore vApp-1 first, then restore vApp-2 into vApp-1
