Abstract
A method for use in a storage system, comprising: detecting that a backend track is required to be deleted, the backend track currently being in an allocated state; identifying a repetition probability score for data that is stored in the backend track; detecting whether the repetition probability score satisfies a predetermined condition; when the predetermined condition is satisfied, transitioning the backend track from an allocated state into a delayed release state, removing any associations between the backend track and one or more frontend tracks, waiting for a predetermined waiting period, and transitioning the backend track from the delayed release state into a free state, wherein the backend track is transitioned into the free state only if no write requests are received at the storage system which include user data matching the data that is currently stored in the backend track.
