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 receives at least one request from a file system to write at least one dataset to a logical page of the solid state memory. At least one physical page in a data block of the solid state memory associated with the logical page is identified. At least one dataset in the physical page is stored. At least one data versioning tag is associated with the dataset in a data structure associated with the logical page. The data versioning tag identifies the dataset as a given version of the logical page. The dataset is maintained as accessible from the physical page irrespective of subsequent write operations to the logical page.
