IntelliSnap Backup on NFS Volume

You can perform a IntelliSnap backup for Oracle when the database is on a NFS Volume. However, you need root access in the storage device's NFS configuration to be able to read and write the accessible Oracle files to the host on which the NFS Volume is mounted.

You can also perform IntelliSnap backups for Oracle if the database resides on a direct NFS volume. IntelliSnap backups support volumes that use the Oracle Direct NFS (dNFS) protocol.

File level revert is performed by default when revert restore is run on NFS volumes. For Volume Level revert on NFS volumes, use the sUSE_FILE_LEVEL_REVERT additional setting. You cannot perform a file-level revert when the database resides on regular SAN Volumes (LUNs).

Consider the following while performing an IntelliSnap backup for data or databases that reside on an NFS Volume:

  • The export name on the storage device should be the same as the storage path on the storage device.

    E.g., if the storage path of the storage device is /vol/Volume/Qtree, use /vol/Volume/Qtree as the export name and not an alias such as /ExportName.

  • You can use the exports both at the root of a NetApp volume and at subdirectory levels below the root of the volume.
  • Make sure that the storage device is accessible from the source and proxy machine (even if they exist in different domains) using the storage device's short name while mounting NFS exports from the storage device. Make sure to enter the storage device credentials using its short name. Do not use an IP address or the fully qualified domain name.

    E.g., use a short name for the server such as server1 or server2.
