Abstract: A system and method for storage medium group parity protection stores data files and related parity information asynchronously on an array of storage media. Data files can be stored asynchronously, or synchronously in stripes as in RAIT technology, but related parity information is stored asynchronously with respect to the data files. Regions of the storage media are preferably organized into protection groups for which parity information is generated. Parity information is generated on line as data files are stored and maintained in active memory. Once a protection group is filled, the parity information is migrated to more permanent backup storage. As one example, regions of an array of N storage media can constitute a protection group, and once the regions in the protection group are filled with data, parity data for the protection group is migrated from active memory to more permanent backup storage.
