Abstract:
A method for extending data lifetime for reference in deduplication is provided. The method includes determining that a quantity of user data has at least a threshold amount of data that is re-created in a storage system. The method includes protecting at least portions of the quantity of user data from erasure by garbage collection in the storage system during a predetermined time interval, wherein the protected at least portions are available for data deduplication of further user data in the storage system during the predetermined time interval.
