Abstract
Systems and methods are disclosed for multiple duration deduplication entries. A processor may be configured to perform data deduplication operations, including setting a first indicator for first metadata stored to a hash database identifying a first time interval to maintain the first metadata in the database, and setting a second indicator for second metadata stored to the database identifying a second time interval to maintain the second metadata in the database longer than the first time interval. The processor may remove the first metadata from the database when no duplicative data is detected for the first metadata within the first time interval, and remove the second metadata from the database when no duplicative data is detected for the second metadata within the second time interval.
