Multi-disk based data storage unit and tape emulation system for offsite data backup

摘要

The invention contemplates a disk based data storage unit. The storage unit includes a plurality of disk drives all within a self-contained unit. The data storage unit may resemble a suitcase and may be ruggedized. The data storage unit may include a handle and possibly wheels to simplify transport of the data storage unit. The data storage unit can replace a plurality of tape cartridges or disk cartridges. A user backs up data onto the storage unit and then moves the storage unit off-site. The suitcase-like form factor and suitcase transporting features allow for easy transport of a large volume of data. Emulation may be used to facilitate communication between the data storage unit and a host computer executing data storage tape software commonly used in data backup and archive applications.
