BACKUP OBJECTS FOR FULLY PROVIDED DATA MEDIA WITH THIN LISTS OF CHUNK SIGNATURES

摘要

Examples might include backup objects for fully mounted volumes with thin lists of chunk signatures. Examples may generate one or more complete lists of chunk signatures for the address space of a fully provisioned volume, compare each chunk signature of the complete list with a chunk signature for an unused area that represents a chunk of an unused area of the fully provisioned volume, Generate metadata to indicate used areas of the fully mounted volume based on the comparisons, and generate one or more thin lists from the one or more complete lists that omit any chunk signatures for which a match with the chunk signature for the unused area has been detected.
