Abstract
Methods are provided for detecting the processing status of data blocks in systems having intermittent connections. A hash value is used at times in place of a block's data content, thereby reducing processing of the block. Hash values may be maintained locally. Blocks collected locally may be stored locally at least until a connection to a server becomes available again. Systems and configured storage media are also provided.
