Creating a Storage Policy for SnapVault or SnapMirrorSnapVault 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.
Warning: 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||Details|
|OnCommand Unified Manager (OCUM) server information||You will need the IP address 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. In the Array Management dialog box, from Type, select OCUM.
|Library details||You can choose libraries for the primary copy and the snapshot copy.
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.
In the procedure below, you use a 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.
