Then a first plurality of index entries for locating a first set of blocks are stored in the index, wherein blocks within the first set of blocks are blocks that store current first versions of the data items. Finally, a second plurality of index entries for locating a second set of blocks are stored in the index, wherein blocks within the second set of blocks are blocks that store non-current second versions of the data items.
