The Status 50 you show actually ocurrs after the backup completes successfully
This indicates a communication issue between the Client and Media Server and The Master Server
Quite a few of these also appear:
20:10:28.053: [2148.2476] <16> dtcp_write: TCP - failure: send socket (736) (TCP 10054: Connection reset by peer)
20:10:28.053: [2148.3008] <16> dtcp_write: TCP - failure: attempted to send 1 bytes
20:10:28.053: [2148.3008] <16> tar_base::keepaliveThread: INF - keepalive thread abnormal exit :14
Also listed are these:
11/19/2012 10:15:37 PM - Error bpbrm(pid=7520) from client 043-sas01-210d: ERR - Unable to backup System State or Shadow Copy. Please check the state of VSS and associated Writers.INF - EXIT STATUS 69: invalid filelist specification
So .. things to check ...
1. As the clients are Windows 2000 and XP what version of the NBU Client do you use on them
2. If they are an old client are they using VSS or VSP for the open file backups? (Master Server Host Properties - Client Attributes
3. What are the client read and client connect timeout values on the media server (they may need increasing)
4. Does a netstat -a on the Master / Media show a large number of ports in use? If it is a Master/Media Server it may be running out of TCPIP ports to use and hence loss of communication, even internally. If this is the case then do the following:
From an administrative command prompt run:
netsh int ipv4 set dynamicport tcp start=10000 num=50000
This greatly increase the number of TCPIP ports available for a Windows 2008 Server
Also go to:
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\
and add a new DWORD named TcpTimedWaitDelay with a decimal value of 30 and then reboot the server.
You can do these settings anyway as they will help the system - then try points 1 to 3 above one at a time - Hope this helps
