Veritas NetBackup™ Snapshot Client Administrator's Guide

Notes on NAS_Snapshot methods

The following notes apply to backups that are made with the NAS_Snapshot method:

  • Snapshots of NAS host data are supported for NetBackup clients running Windows (32-bit system and 64-bit system), Solaris, Linux, and AIX.

  • Note these software requirements and licensing requirements:

    • On the NetBackup server, both NetBackup for NDMP and Snapshot Client software must be installed and licensed. In addition, a NetBackup for NDMP license must be purchased for each NDMP host (filer).

    • NetBackup clients that are used to perform backups must have Snapshot Client installed.

    • On NetBackup clients for Oracle: NetBackup for Oracle database agent software must be installed on all clients.

  • The NAS host must support NDMP protocol version V4 and the NDMP V4 snapshot extension, with additional changes made to the snapshot extension. The NetBackup Snapshot Client Configuration online pdf contains a list of NAS vendors that NetBackup supports for NAS snapshots. This online pdf includes requirements specific to your NAS vendor.

    See: http://www.veritas.com/docs/000081320

  • NetBackup must have access to each NAS host on which a NAS snapshot is to be created. To set up this authorization, you can use either of the following:

    • In the NetBackup Administration Console: the Media and Device Management > Credentials > NDMP Hosts option or the NetBackup Device Configuration Wizard.

      OR

    • The following command:

      tpconfig -add -nh ndmp_host -user_id user_ID -password password
  • The client data must reside on a NAS host and be mounted on the client by means of NFS on UNIX or CIFS on Windows. For NFS mounts, the data must not be auto-mounted, but must be hard (or manually) mounted.

  • For NAS snapshot, you must create a NAS_Snapshot policy.

    See Setting up a policy for NAS snapshots.

  • On Windows clients, to restore files from a NAS_Snapshot backup, the NetBackup Client Service must be logged in as the Administrator account. The NetBackup Client Service must not be logged in as the local system account. The Administrator account allows NetBackup to view the directories on the NDMP host to which the data is to be restored. If you attempt to restore files from a NAS_Snapshot and the NetBackup Client Service is logged in as the local system account, the restore fails.
