I recently migrated from a DPM 2012 R2 local SQL instance to DPM 2016 UR4 connecting to a separate SQL server and we backup to tape using Firestreamer. The child server is 2016 running on a 2012 R2 parent. I am having a repeat problem where the tape backup eventually slows to a stop, all other jobs will stop synchronising etc. and the server in general slows to a crawl.
Restarting the firestreamer service does not do anything
You can't restart any of the DPM services
RAM and CPU usage are normal, however I cannot see disk usage in Performance Monitor, the various sections are blank
Reinstalling Firestreamer works for a few days and then the issues reoccur
It happens across different disk sets.
Any ideas would be greatly appreciated.
