Virtual worm method and system

摘要

A system and method of storing data using write once read many (WORM) protection including using a hardware storage device to write data to a medium are provided. The method further includes establishing a write once read many (WORM) module external to the hardware storage device. Data blocks are received at the module, block numbers are specified with the module, and data is output from the module to write to the storage medium at specified block numbers. The last specified block number or all specified block numbers depending on the type of media access are stored so that the external WORM module prevents future writing of data to these specified or already used block numbers.
