Analyzing backup objects maintained by a de-duplication storage system

摘要

Analyzing backup objects maintained by a de-duplication server. A plurality of first objects may be maintained. Each first object may refer to second object(s) and each second object may refer back to at least one first object. For each respective first object, the respective first object may be analyzed to determine the one or more second objects referred to by the respective first object. Correspondingly, a command may be generated for each respective second object of the determined second object(s), thereby generating a plurality of commands. Each command may be used to verify that the respective second object refers back to the respective first object. The plurality of commands may be sorted into a disk access order. The commands may be used to verify that each second object refers back to first objects that refer to the second object.
