Abstract
A method may comprise caching a portion of a pool of unique data blocks in a memory, the pool of unique data blocks comprising a plurality of unique blocks, at least some of the plurality of blocks in the pool of unique data blocks being referred to in at least one reference file. A list of blocks may be updated with any block in the cached portion of the pool of unique data blocks that is not referred to by at least one reference in the reference file(s). Different portions of the pool of unique data blocks may then continue to be cached and the list of blocks not referred to by at least one reference may be updated until the remaining portions of the pool of unique data blocks are cached. The blocks in the list of blocks may then be deleted from the pool of unique data blocks.
