Abstract
Method and apparatus for copying, transferring, backing up and restoring data are disclosed. The data can be copied, backed up or restored in segments sizes larger than the data blocks which comprise a logical object. In some embodiments, the segment can correspond to a track of a primary storage device and the data blocks to a fixed size block. In some instances, copying, storage and transfer of the segments which include multiple data blocks can result in transfer of a data block not in a logical object.
