DES-3128 Exam Dumps : Dell EMC NetWorker Specialist for Implementation Engineers

To troubleshoot why a customer cannot see any files backed up when a restore operation is attempted on their 3 new Linux server named Server01, the first step should be to check the log files for any error messages. The log files are typically located in the /var/log/ directory, but the exact location may vary depending on the operating system being used.

Next, the administrator should check the configuration of the NetWorker server to ensure that the server is configured correctly. This includes checking the client configuration for the Server01 and making sure that the correct client name is being used. Additionally, the administrator should make sure that the Server01 has the correct address and port information, as well as the correct credentials.

The administrator should also check the configuration of the server to make sure that the correct backup policies are being used and that the backup schedule is configured correctly. Additionally, they should check the configuration of the actual backup device, such as the tape library or disk array, to make sure that it is configured properly.

Finally, the administrator should check the filesystem of the Server01 to make sure that the backup files are actually being written to the correct location.

This behavior can occur when persistent naming is enabled on the storage node. When persistent naming is enabled and the storage node is rebooted, the library and tape drives may no longer be accessible because the persistent naming is lost.
