I am evaluating DPM 2012 R2 in a lab environment using the DPM 2012 R2 Evaluation VHDs provided by Microsoft at the following link:
http://www.microsoft.com/en-my/download/details.aspx?id=40838
The lab environment is hosted on a single Hyper-V 2012 host which the DPM 2012 R2 VHD resides on. The DPM 2012 R2 environment has been domain joined per the instructions in the lab. DPM 2012 R2 is being used to perform disk backups for the VMs on the Hyper-V host and a few SQL instances on a SQL server.
DPM fails to backup the SQL instances and provides the following message for each database in the Monitoring workspace:
The replica of SQLServer\SQLInstance\SQLDatabase on SQLServer.Domain.Net is inconsistent with the protected data source. All protection activities for data source will fail until the replica is synchronized with consistency check. (ID: 3106)
DPM is unable to continue protection for SQLServer\SQLInstance\SQLDatabase on SQLServer.Domain.Net because the change tracking information is corrupt (ID: 30156)
There are no errors in the DPM Server Application log. The DPM Alerts log generates the same error. The DPM Backup Events displays the following Warning:
Backup job for datasource: SQLServer\SQLInstance\SQLDatabase on production server: SQLServer.Domain.Net failed.
Backup job failed at: 10/27/2013 11:44:22 AM.
Backup Type: disk backup.
Running the "synchronization job with consistency check" fails within a few seconds and each of the above error messages are generated again.
The SQL server is a SQL 2012 SP1 standalone virtual server. It is not clustered. The "NT Service\DPMRA" account has been given SA permission per the TechNet documentation.
DPM is able to backup the Virtual Machines themselves to disk without error.
