ABSTRACT:
Information is retrieved by receiving a list of one or more files to be restored. It is determined whether to obtain: (1) a contiguous group of blocks that includes a first segment of one or more blocks associated with the one or more files to be restored, a gap of one or more blocks that are not associated with the one or more files to be restored that is adjacent to the first segment, and a second segment of one or more blocks associated with the one or more files to be restored that is adjacent to the gap or (2) a contiguous group of blocks that includes only the first segment based at least in part on a length and/or number of blocks comprising the gap. The determined contiguous group of blocks is obtained.
