As long as both actions are using same ddboost device we are fine . You might want to stop and start nsrbbb before backups .
Sc stop nsrbbb
SC start nsrbbb
Hey please check event log for any errors on MSexchangerepl . There might be some network issues with DAG. May be transport connection issues . If issues persist create SR with support, may be support already is aware of this issue and have fix for it like nsrnmmsv.exe patched binary
Thanks for your replies.
Checked that we are running to the same device etc and everything looks fine. I will open up a SR with support and see what happens. I will update this thread if we get it resolved
