ABSTRACT:
Methods are provided for detecting the processing status of data blocks. A hash value is used at times in place of a block's data content, thereby reducing processing of the block. Superblocks and superblock hash values are used to manage collisions between hash values of individual blocks, in order to reduce or eliminate the risk that blocks having different content will be treated as though they have the same content merely because they have the same hash value. Systems and configured storage media are also provided.
