Abstract:
One or more embodiments are directed a solid state storage device for maintaining versions of data. The solid state storage device comprises a processor and a solid state memory communicatively coupled to the processor. A flash translation layer is configured to perform a method comprising creating at least one data structure associated with at least one logical page of the solid state memory. The logical page is associated with at least one physical page in a data block of the solid state memory. A first set of information associated with the logical page is stored in the data structure. A second set of information associated with the physical page is stored in the data structure. The second set of information comprises at least versioning information identifying which version of the logical page is represented by a dataset stored within the physical page.
