DPM is great for backing up Microsoft stuff but I ran into something really, really odd. In short, the msdpm kept crashing. I took a while but I was eventually able to track down which object was causing the crash by trying each failed sync one at a time. (DPM troubleshooting step 1.) For the record, it was the system protection for a Windows Server 2012 R2 server but I’m not convinced that that matters.
