Clean install of both Server 2012 R2, DMP 2012 R2, and SQL 2012 SP1
Everything is patched and current.
However, all backup jobs fail after 1 hour and 20 min with: The protection agent on MYDPMSERVER.WTF was temporarily unable to respond because it was in an unexpected state. (ID 60 Details: Internal error code: 0x809909B0)
This happens regardless of the server OR client i'm attempting to backup. Backup jobs WILL complete successfully, if the amount of data is being backup'd up can be moved in under 1 hour and 20 min.
Anyone having a similar issue? I'm at a total loss.
