DYNAMICALLY-ADJUSTABLE DEDUPLICATION ORDER OF OPERATIONS

Abstract:

An information management system can dynamically adjust the order in which compression and deduplication operations are performed based on the type of file for which a secondary copy operation is requested. For example, the information management system can determine whether the file for which a secondary copy operation is requested is a first type of file that is text-based and/or that has data blocks that are highly compressible or a second type of file that may have data blocks that are not highly compressible. If the information management system determines that the file is of the second type, the information management system can perform a deduplication operation prior to performing a compression operation. Furthermore, the information management system can dynamically adjust the size of various deduplication blocks based on the type of file for which a secondary copy operation is requested.
