    Abstract: The invention introduces an apparatus for facilitating deletions of file data that is protected by copy-on-write (COW) snapshots, at least including a storage device and a processing unit. The processing unit calculates release estimates for accumulated inspection sets, each of which includes one or more identities (IDs) of first COW snapshots, deleting second COW snapshots with references made to the release estimates, and deleting the sets of file data that are invisible from a directory tree and are not protected by any COW snapshot after the second COW snapshots are deleted.
