NetBackup status code: 251

Message: the tir information is zero length

Explanation: For a true-image backup, the client sent no file information to the master server. NetBackup discovered this condition when it tried to write the TIR information to media.

Recommended Action: Check the policy file list and the exclude and include lists on the client to verify that the client has eligible files for backup. For example, this status code can appear if the exclude list on the client excludes all files.

To obtain detailed troubleshooting information, create debug logs for bptm or bpdbm on the server. Then, retry the operation and check the resulting debug logs.
