The abstract of the patent published by the U.S. Patent and Trademark Office states: “Multitier deduplication can reduce the amount of bandwidth and storage resources used during deduplication. In certain embodiments, the system can determine if a data block is stored in a first archive data storage. If so, the system can skip the data block. If not, the system can determine if the data block is stored or identified in a second archive data storage. In various implementations, the first archive data storage can be local to the system and the second archive data storage can be a global archive that may be remote from the system. The system can create a map of a plurality of backups stored at the first archive enabling the system to quickly check multiple archives. The multitier data deduplication can filter out inactive data blocks during or before performing the deduplication process.“

The patent application was filed on August 25, 2011 (13/218,362 ).
