Abstract: A system for controlling access to an electronic resource can comprise a set of sensors and one or more processors. A first sensor in the set of sensors may detect first data indicating a characteristic of a user of the electronic resource.

Machine language determines using deduplication metadata that at least some of an incoming input/output stream is a duplicate of at least part of a source volume whose physical locations of its stored data are fragmented in backend storage. Subsequently, defragmentation is carried out on the stored data by using the incoming input/output stream to write the data into sequential chunks at new physical locations in the backend storage and updating the source volume location mappings to the new physical locations.
