Abstract: A method for performing deduplication management with aid of a command-related filter and associated apparatus are provided. The method may include: utilizing at least one program module among multiple program modules running on a host device within the storage server to control the storage server to write multiple sets of user data of a user of the storage server into a storage device layer of the storage server, and utilizing a fingerprint-based deduplication management module among the multiple program modules to create and store multiple fingerprints into a fingerprint storage of the storage server to be respective representatives of the multiple sets of user data at the storage server, for minimizing calculation loading regarding deduplication control; and utilizing the command-related filter to at least convert a set of commands into a single command to eliminate unnecessary command(s), for executing the single command rather than all of the set of commands.
