Creating a Storage Policy and a Snapshot Copy for SnapVault or SnapMirror

SnapVault allows a secondary NetApp file server to store SnapProtect 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.

About This Task

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

Before You Begin

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

Information that you need Details
OnCommand Unified Manager (OCUM) server  information To access the OCUM server information

If you want to provide the OCUM server information later, see Configuring the NetApp Array Using Array Management. In the Array Management dialog box, from Type, select OCUM.

Library details You can choose libraries for the primary copy and the snapshot copy.
  • The name of the library to which the primary copy should be associated. The initial library for the storage policy.

    We recommend that you select the disk library that uses a logical unit number (LUN) from the file server.

  • The name of the library with which you want to associate the snapshot copy.

    Default: The primary copy library is selected.

Deduplication details

Default: Source-side on primary copy.

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.

Note: You can enable deduplication only 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.
  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.
