Maintaining versions of data in solid state memory

A method for maintaining versions of data within a solid state memory, the method comprising:

• receiving, by a flash translation layer, at least one read request from a file system to perform a read operation, the read operation configured to read at least one dataset from at least one physical page associated with a logical page of a solid state memory, the at least one read identifying the logical page;
• identifying at least one physical page associated with the logical page;
• retrieving a dataset from the physical page;
• retrieving a data versioning tag associated with the dataset from a tag area within the flash translation layer, the data versioning tag comprising at least
• a version identifier identifying the dataset as a given version of a dataset associated with the at least one logical page, and
• a file/directory identifier identifying one of a file and a directory within the file system corresponding to the physical page from which the dataset was retrieved, where physical pages corresponding to one of a given file and a given directory are associated with a same file/directory identifier;
• and
• sending the dataset and the data versioning tag to the file system.
