Unable to NFS mount the required file system

Level 3

Hello everyone,

While taking AD backup one day is completely successful and the other day is partially successful. When I look at the details of the job that has been partially completed successfully, I can actually see that the system state is fully backed up. Also, when I look at the backup, archive and restore screen, I see that grt is available for a partially successful backup. Is there anyone who can help with the reason for partial successful completion? In fact, if the backup is successful, I have to find out why it is partially successful.

This may be caused due to an issue with the Client for NFS service.

Have a look on this article:


Level 4

Hello @probck 

I advice you to uninstall client for NFS, after that you reboot the server, and install again the client for NFS.

Level 4

This is your mail culprit 

29.May.2020 10:15:34 - Error bpbrm (pid=9784) from client client_name1: ERR - Unable to NFS mount the required file system.

Does The server also have Data on NFS ?

Please check Server Event Logs about NFS . There is an issue with that. 

An Uninstall of NFS Windows client and reinstall may fix the issue.

But Let us know if you see NFS Related errors in Event Viewer.
