Backup Exec requires at least one storage media drive and/or single-drive
robotic library. Removable storage devices and non-removable hard drives can
also be targeted for backups. Refer to the
Backup Exec hardware
compatibility list for a complete list of devices that are supported.
Note: Support for a single robotic library drive is available when you
purchase Backup Exec. To enable support for additional robotic library
drives, you must purchase Backup Exec Library Expansion Option.
