Your task is to develop a backup-to-disk solution for your client. After an initial analysis, you decide to include one EMC Disk Library (EDL) to be used as the primary backup device. The customer has been using a physical library with LTO-3 drives for many years and would like to have the capability to recover from the old tape. The solution must result in the fewest possible changes to the EMC NetWorker server. How can you best address these requirements?
