Abstract
A method and system for employing fast, but easily corrupted mass storage for reliably backing up objects, such as files and databases. In a LUN-based mass storage device, a system or application may request and receive a lock on a particular LUN prior to storing a backup object on the LUN. The system or application may later request lock information for the LUN in order to decide whether or not the backup object can be reliably used for a restore operation. If the system or application continues to hold a lock on the LUN, then the backup object is reliable.
