Problem:
The following messages are displayed in the logs when attempting to restore a VM to its original location:
Handler 'VMwareESX' call failed: Restore failed to recover all the required VMs
Restore failed to recover all the required VMs *** Attachment count: 1 ***
The attachment identifies the VMDK file associated with the VM that failed to restore.
Cause:
If a VM only resides on one datastore, Protector will not consolidate that VMs snapshots when it is restored (thus all its intermediate snapshots are preserved). This can cause a restore failure under certain conditions.
Solution:
Try selecting Clone instead of Original location when specifying the restore location in Protector. This will cause Protector to consolidate the VM's snapshots.
