VDP: Host is in a state that cannot perform snapshots

[fiercepowahs]

We have an VDP Appliance that is backing up one Guest VM fine but the second Guest VM it continues to error out after 10-30 seconds stating "VDP: Host is in a state that cannot perform snapshots."

I can manually create a snapshot within vCenter. I have rebooted the machine countless times trying all sorts of things based on articles I've found on the internet. I have reinstalled the VM Tools three times. There are no errors in either the system or application log in windows. There are no vssadmin list errors.

I have gone down many of the articles listing similar issues:

The server is currently running Windows 2008 R2 with local disks for Storage. No SAN connections.

Full Error in vCenter:

10/21/2013 16:26:19 PM: Backup job named "Server 2 WFL Server" completed.
10/21/2013 16:26:19 PM: Task execution failed.

This was ultimately solved by rebooting the vsphere host.

Have you faced this issue again? I mean was the restart a permanent solution or you have to restart your host from time to time? We have the same issue, and I wonder if we should restart the host and get rid of this problem once forever or open the case to find a permanent solution?

I ran into this as well.  in the End the solutions was to just rescan the datastores on each ESX host.  Once completed the Backups worked fine.  Vmware KB  VMware KB: Backing up using hosts VMware vSphere Data Protection fails with the error: cannot perfor...

In my situation, it turned out that I had a host disconnected. I had to reconnect it and then run the backups again. Everything appears happy again.
