Create the folder if it does not exist.

trxn log backups are running perfectly fine.

Solution

Checked the task manager and there were many hung dbbackex.exe processes
Terminated the hung dbbackex.exe processes

Hi Will

I checked , but there are no dbbackex.exe process :(

Apologies - missed the posting of dbclient log file. It looks like a timeout to me. Connection to master server was successful but no data was transferred in the following 5 minutes. 11:17:35.873 [8288.9484] <2> logconnections: BPRD CONNECT FROM 10.100.19.166.52799 TO 10.100.14.127.1556 fd = 884 11:17:35.873 [8288.9484] <2> vnet_check_vxss_client_magic_with_info: [vnet_vxss_helper.c:843] Assuming no VxSS for DB Agents 0 0x0 11:20:14.196 [8288.9948] <4> bsa_JobKeepAliveThread: INF - sent 10 keep alives. 11:22:35.916 [8288.9484] .... At this point the Read timeout will kick in. Check timeouts on master and media server. Change it to 1800. I am curious about something else I see in the log. We will need bprd log on the master server to find the reason for this status 37: 11:22:35.990 [8288.9484] <4> dbc_RemoteWriteFile: ulvmctmdat007.internal.colt.net root 37 logs/mssql_backup_failures/021715.rpt a 1
