Hello,
I'm managing a two nodes 2012 R2 file server cluster that contains a 16To CSV. I'm using DPM 2012 R2 to backup this entire shared volume directly to LTO 4 tapes, the job last about 55h.
Since SCCM 2012 client has been installed(I don't manage it), the tape jobs are failing ramdomly after several hours with the error:
Type: Tape backup
Status: Failed
Description: The DPM service was unable to communicate with the protection agent on serverX.xxxx.xxx . (ID 52 Details: The semaphore timeout period has expired (0x80070079))

If I uninstall SCCM 2012 client, no more issue, backups succeed. I've asked our SCCM team, no specific task has been scheduled or deployed in SCCM.
I can't see anything abnormal in logs.
Any idea?
