Dell NetWorker 19.9 Administration Guide

Advantages

The advantages of cloning data to physical tapes include the following:

• Cloning can occur with the disk libraries under NetWorker control with standard NetWorker policy support. You can use multiple retention policies for different cloned copies of the data.
• Cloning can occur at the save set and volume level.
  NOTE:NetWorker can clone a single save set, multiple save sets or all of the save sets on a volume.
• Copying can occur from one tape type (virtual) to another tape type (target tape library), also known as tape conversion.
• Copying can occur from multiple virtual tapes to a single tape, also known as tape stacking.
