Creating a Storage Policy for SnapVault or SnapMirror

SnapVault allows a secondary NetApp file server to store IntelliSnap snapshots. Multiple primary NetApp file servers can back up data to this secondary file server.

In the first backup, the complete contents of the source are transferred, to establish a baseline. In subsequent backups, typically, only the changed blocks are transferred. After the first backup, snapshots of data on the destination volume are taken, and you can maintain the snapshots independently for recovery.

SnapMirror is a replication solution that you can use for disaster recovery, where the complete contents of a volume or a qtree are mirrored to a destination volume or a qtree.

For SnapVault replication and SnapMirror replication using the OnCommand Unifed Manager (OCUM) server, if the subclient contains data from multiple file server volumes, then a target volume is provisioned per source volume.

Before You Begin

Caution: To avoid the risk of data loss, you must configure SnapVault with NetApp command lines.

Use the following table to gather the information that you need when you create a storage policy.

Information that you need


OnCommand Unified Manager (OCUM) server information

You need the IP address of the OCUM server or the name of the OCUM server.

If you want to provide the OCUM server information later, see Configuring the NetApp Array Using Array Management.

Library details

You can choose the libraries for the primary copy and for the snapshot copy. Libraries store index information for snapshot backup jobs. Use a disk library.

Tip: By default, the primary copy library is selected.

  • You need the name of the library that you want to associate to the primary copy.
  • You need the name of the library that you want to associate to the snapshot copy.

Deduplication details

You can accept the default values, or you can configure the Partitioned Deduplication Database (DDB) to host the DDB on multiple MediaAgents. For more information about partitioned DDBs, see Deduplication Database.


  • The default setting is the source-side on the primary copy.
  • You can only enable deduplication when you create a storage policy.


  1. In the CommCell Browser, expand Policies.
  2. Right-click the Storage Policy, and then click New Storage Policy.

    The Create Storage Policy Wizard appears.

  3. Follow the instructions in the storage policy creation wizard. On the Enter storage policy name page of the wizard (the second page), select the Provide the OnCommand Unified Manager Server information check box.
  4. Click Finish.

    Under the Storage Policies node, the Storage Policy with Primary Snap Copy (for local snapshot storage) and Primary Classic Copy (for backup copy to tape, disk, or cloud) appear.
