At least a portion of data of a tree data structure is serialized into a first set of flat data. At least a portion of a structure of the tree data structure is serialized to reproduce at least the portion of the structure in a second set of flat data. It is determined to access a desired data of the tree data structure from an archive. The second set of flat data is read to reconstitute at least the portion of a structure of the tree data structure. The reconstituted structure of the tree data structure is used to determine a data offset associated with the first set of flat data, wherein the data offset corresponds to the desired data. The desired data is accessed using the data offset associated with the first set of flat data.
