Using SnapMirror for Data protection

You can use SnapMirror, an optional feature of Data ONTAP, to replicate data from specified source volumes or qtrees to specified destination volumes or qtrees, respectively.

You require a separate license to use SnapMirror.

After the data is replicated to the destination storage system, you can access the data on the destination to perform the following actions:

•	Provide users immediate access to mirrored data if the source goes down.

•	Restore the data to the source to recover from disaster, data corruption (qtrees only), or user error.

•	Archive the data to tape.

•	Balance resource loads.

•	Back up or distribute the data to remote sites.

System Manager cannot manage SnapMirror relationships that are configured using SnapMirror connections, vFiler units, or preferred interfaces. System Manager uses the storage system name that is specified in the SnapMirror relationship to query the storage system. The host resolution fails because the connection name, vFiler unit name, or the preferred interface name is not same as the storage system name. You must add both source and destination systems to System Manager.
