Abstract

A backup appliance comprising secondary storage medium partitioned into storage bins, either operatively attached to the computer or operatively detached from the computer Upon storing a copy of the computerized data in one of the storage bins, operatively attaches or mounts the storage bin solely for reading operations and maintains a stored value of a parameter of the copy The processor penodically compares the stored value to a corresponding value of the checksum of the computerized data Upon detecting a discrepancy between the stored value and the corresponding value when the discrepancy originates from the computerized data, the computerized data is restored from the copy and when the discrepancy originates from the copy, either (ι) the copy is restored from the computerized data or (ιι) another copy of the computerized data is restored in another storage bin.
