The system generates serial numbers to identify tapes and writes the serial number onto the tape media. However, these serial numbers are not visible to users. If your tape device does not support barcode technology, you must manually locate tapes. Unitrends strongly recommends that you develop a labeling system for easy management of your tapes. When you label a tape, make sure to include the slot number the tape occupied when it was used for an archive job and other identifying information that will enable you to locate the tape.
