To mount the NFS share and configure the catalog backup policy:

1. On the NFS server, run the following command to create a directory for the NFS share:

   mkdir <NFS directory>

2. Navigate to /etc/exports and add the following directive:

   <NFS directory> <primary IP address>(rw,no_root_squash)

   Where <NFS directory> is the directory that you created, and <primary IP address> is the IP address of the primary server instance.

   For example:

   /nfsdir 11.11.11.111(rw,no_root_squash)

3. Restart the NFS service or reload the configuration file with the exportfs command.
4. Log in to the primary server instance as the appadmin user and run the following commands:

   sudo bash

   cat > /mnt/nbdata/vxos/etc/fstab

   <NFS IP address>:<NFS directory> /mnt/nbcatdr nfs nfsvers=<NFS version>,rw,x-mount.mkdir

   Where <NFS IP address> is the IP address of the NFS server, <NFS directory> is the directory for the NFS share, and <NFS version> is either 3 or 4.

   For example:

   22.22.22.222:/nfsdir /mnt/nbcatdr nfs nfsvers=3,rw,x-mount.mkdir

5. From the Flex Appliance Console, restart the instance.
6. Log back in to the instance and run the following command:

   chown -R nbsvcusr:users /mnt/nbcatdr

7. From the NetBackup web UI, select Protection > Policies and click Add. Follow the prompts to configure a backup policy with the type NBU-Catalog. Specify the following information for the catalog disaster recovery file:

   • Path: /mnt/nbcatdr/

   • Logon and Password: Leave empty
