Backup Failure with authentication Credential alert!

Hello Guys ,

I've deployed Networker and Client side Networker user for SQL server.

Yesterday I Got a schedule backup failure with below message on NSR Log. Can any of you guys help me with the root cause?

Re: Backup Failure with authentication Credential alert!

Sometimes this warning can occur if there is not a servers file under \Legato\nsr\res or the NetWorker server name is not specified in the "servers" file.


1. Create a file called 'servers' under \Legato\nsr\res.

2. Specify the NetWorker server name in it.
