System Center DPM 2012 R2 Update Rollup 8 has been out for a month now, we spent a lot of energy in this UR to focus on quality and are getting good feedback from thousands of customers who already installed the update. As a result, we have now made it an “Important Update” on Microsoft Update, so it will be pushed automatically to wider audience and more customers can benefit from all the reliability fixes.

We would recommend customers to upgrade to UR8, if not done already. Below is a recap of the major reliability fixes we made in DPM UR7 and UR8, for more detailed list of bug fixes and features please refer to respective DPM UR KB articles .

Below are some of the important issues that we fixed since DPM UR7
DPM console crash issues.
If you try to back up a SharePoint site that uses SQL Always On as a content database, SQL logs are not truncated resulting in SQL disks to become full.
If you have multiple SharePoint farms hosted on the same SQL cluster, with different instances but the same database names, DPM cannot back up the correct SharePoint farm content.
You try to back up Hyper-V virtual machines (VM) that have a replica and both the Active virtual machine and the Replica virtual machine are managed by the same System Center VMM server. Previously, you had no control to select between Active and Replica virtual machines for backup. This frequently caused backups to fail, depending on the setup.
If you try to protect large number of virtual machines in a single Protection Group, and you have the VMM Helper Service enabled, some backups may fail with "System.TimeoutException".
In some cases, alerts that are resolved in DPM are not synced in the DPM Central Console.
If you are trying to recover data from an imported tape, DPM may crash with a "Connection to the DPM service has been lost" error.
When you try to protect a SQL failover cluster, the Data Protection Manager UI may crash for backup or synchronization operation.
DPM self-service recovery for SQL databases may fail with the error “Cannot connect to DPM server …”
End User Recovery/SSRT may not work in some cases for mirrored SQL databases.
You cannot protect a SQL database on an Availability Group (AG) if different AG have the same database name.
