Hyper-V (WS2012) Backup on Guest VM (WS2008)

If you're running backup jobs (e.g. DPM2012) on WS2012 Hyper-V with older guest VMs (e.g. WS2008), you might encounter this error:

The replica of Microsoft Hyper-V \Backup Using Child Partition Snapshot\[VM] on [Host] is inconsistent with the protected data source. All protection activities for data source will fail until the replica is synchronized with consistency check. You can recover data from existing recovery points, but new recovery points cannot be created until the replica is consistent. 

For SharePoint farm, recovery points will continue getting created with the databases that are consistent. To backup inconsistent databases, run a consistency check on the farm. (ID 3106) 

To resolve it,
1) ensure that the host contains this update KB2770917 (available in Windows update)
2) Update the Integration services on the older guest VMs e.g. WS2008R2 etc
