DP 10.20 - Virtual CM (W2012), Physical MA (W2K8), Physical DA (W2K8)
I've been trying to diagnose an issue affecting a client in my environment but I'm no closer to resolving it than when I started.
I have a W2K8 R2 client in a domain separate to the CM but reachable through firewall rules.
The client's backup fails intermittently; I have been able to interactively back up its CONFIGURATION object but not its C:\ or D:\ partitions.
The result is the same whether the backup writes to a Tape Library or to one of our HPE StoreOnce devices.
When the backup runs, it writes between 40-116MB and then fails with the message
"[Critical] From: VBDA@3dsecdmcapp1.pcisecure.net "C:" Time: 02/09/2019 17:39:52
Connection to Media Agent broken => aborting."
and exits. No error code, no earlier message to suggest any problems. I haven't seen anything useful in debug logs either.
Omnirc file on the CM, MA and DA contains the following entries:
OB2PORTRANGESPEC=xMA-NET:18000-18025;xSM:20100-20199 (inactive since upgrade to DP 10.0 - reactivated but ineffective)
The service account for Data Protector is in Local Admins on the client, and has the rights "Act as Part of the OS" and "Log On as a Service".
It's strange that I can reach one part of the client but not others - this suggests a security issue but there's nothing that my colleague or I can see that might indicate a lack of user rights.
I'd be interested to learn if anyone has seen this behaviour in DP 10 (or any other version) and has any suggestions on how to resolve it.
Any and all advice welcome.
