DPM Hyper-V Backup Issue

[ITGURU]

I have inherited a DPM backup system which has been backing up some Hyper-V VMs successfully.

I've tried to add some new VMs into the protection group but have an issue.

When I initially add the VM on the replica host, the protection status goes to 'OK' and green.

After a while, or if i preform a backup or run a consistency check, it will come up as failed - Replica is inconsitent

If i try and re-run the consistency check, it says inconsistent still and I get the following error:

 

 

Type: Consistency checkStatus: FailedDescription: An unexpected error occurred while the job was running. (ID 104 Details: The filename, directory name, or volume label syntax is incorrect (0x8007007B))

 

The infrastructure consists of Hyper-V server, with DPM selecting the VMs from the Replica Server

A replication check between the primary and replica server are all green and ok.

 

Please could anyone help ?

 

A windowsimagebackup directly from the VM server successfully completes.

 

The VMs which are currently working ok were added before my time.

It's been a while since I used DPM, but I seem to recall that issues like this were usually because of SQL server permissions - I think the AD users has to be given rights to the DPM database - if it's been done individually, you might have to add yourself, if it's been done by an AD group, you'd probably need to add yourself to that group.
