Dell NetWorker 19.9 Administration Guide

Controlling storage node selection for cloning

You can control the storage node from which clone data is read (read source) and the storage node to which the clone data is written (write source). If you do not specify the read and write source storage nodes, then the cloning operation uses the nsrserverhost or NetWorker server as the storage node.

When you use data protection policies to clone, the selections that you make from Source Storage Node and Destination Storage Node lists on the Clone Options page for the clone action control the read source and write source. The "Creating a clone action" topic provides more information about how to configure a clone action and configure the filters that enable you to define the criteria that NetWorker uses to create the list of eligible save sets to clone.

When you use the nsrclone command, Use the –J recover storage node option to specify the read source host for the original volume and the –d save storage node option to specify the write source for the clone volume. The NetWorker Command Reference Guide or the UNIX man pages provide more information about the nsrclone command.
