Abstract
Various embodiments are directed to maintaining versions of data within a solid state memory. At least one request to write at least one dataset to a logical page of a solid state memory is received from a file system. At least one physical page in a data block of the solid state memory associated with the logical page is identified. A processor stores the dataset in the at least one physical page. At least one data versioning tag is associated with the at least one dataset in a data structure associated with the logical page. The data versioning tag identifies the at least one dataset as a given version of the logical page. The at least one dataset is maintained as accessible from the at least one physical page irrespective of subsequent write operations to the logical page in response to associating the at least one data versioning tag.
