unable to backup particular folder
we have couple of WAN backups in my environment.I have enabled multi streaming.usually it runs quite long time but completes with in schedule/some times after manual re run.
But from last one week ...
All we can see in the log is a break in network connection:
4:51:54.533 PM: [908.5244] <2> tar_base::V_vTarMsgM: DIR - 316 132540 45811565 31 16832 root root 0 1348644992 1315517488 1315517487 /F/u1/s9014079/New Restore PST/ 4:55:02.895 PM: [908.5244] <16> dtcp_write: TCP - failure: send socket (1848) (TCP 10054: Connection reset by peer) 4:55:02.895 PM: [908.5244] <16> dtcp_write: TCP - failure: attempted to send 1 bytes (Lots of these 2 lines......) 4:59:16.648 PM: [908.5244] <2> tar_base::V_vTarMsgW: FTL - tar file write error (40) 4:59:16.664 PM: [908.5244] <2> tar_base::V_vTarMsgW: INF - EXIT STATUS 14: file write failed
Have a look at troubleshooting steps listed for Status 14:■ On Windows systems, the client bpbkar log may contain a 10054 ConnectionReset Error (usually indicates a hardware error). Somewhere between theNetBackup client and server, the connection was reset. When NetBackupreceives this error, it cannot continue the backup. This error has been attributedto the following:■ A hiccup in the network.■ A bad network interface card on a NetBackup client.■ A bad network interface card on the NetBackup server.■ Faulty routers.■ Any other applications that interfere with NetBackup connections.You may want to upgrade to NBU 7.5 and read up on the new Wan Resilient feature.
See this White Paper: http://www.symantec.com/docs/TECH183552
Prior to NetBackup 7.5 release, any disconnection in network over WAN environment will cause backups to fail....
NetBackup 7.5 includes a feature, Resilient Network, which will help data transfers over a WAN environment by becoming resilient to WAN interruptions.
Refer attached document for more details.
