Hello there,

I'm fairly new to using Backup 7.5 and having some trouble with configure our backups. Ive read through the manual and followed the instructions on configuring the settings, but I may have missed something. Any help would be appreciated.

The final status means that your Information Stores are backed up but you will not get GRT (individual messages available to restore)

A number of issues for this but you need to ensure that you have covered all pre-requisites first as per the admin guide.

So briefly ...

Same versions of NBU on Master, Media and Clients (all nodes of the DAG)

NFS configured on Media Servers and DAG members

A mailbox for NBU to use during the GRT proceedure

EWS / NetBackup Clients Service using suitable account on all DAG members

Backup must be going to disk

Distributed Application Restore Mappings section completed on Master Server Host Properties

If any of these are missing it can cause the failure (as can any replication issues with your DAG)

Mark - One more thing... would disabling the "Server for NFS" services on all the servers(Except the NBU media server ofcourse) help with the resolution of this problem? I noticed it was in the documentation, but did not get around to doing this.

As it turns out, I was missing the No.Restrictions file and that was the cause of the issue.

Once I created the file in the proper location, GRT backup ran fine.

Thank you Mark. Let me re-run through all the pre-req's and see if there is anything I missed.
