Backing up a volume to a cluster running Element software
You can back up volumes residing on a cluster running NetApp Element software to a remote Element cluster. When backing up or restoring from one cluster to another, the system generates a key to be used as authentication between the clusters. This bulk volume write key allows the source cluster to authenticate with the destination cluster, providing security when writing to the destination volume. As part of the backup or restore process, you need to generate a bulk volume write key from the destination volume before starting the operation.
