Claim:
A system for copying data stored in an information store, the system comprising: one or more data agent modules executing on a computing device, the one or more data agent modules being configured to, read a plurality of first blocks of data stored in the information store, generate a first mapping of the plurality of first blocks, and transmit a copy of the plurality of first blocks and the first mapping to a storage device by arranging the copy of the plurality of first blocks into one or more chunks, each of the one or more chunks having a header for storing at least a portion of the first mapping, wherein the portion of the first mapping is associated with the copy of the plurality of first blocks in the corresponding chunk; identify block level data changes in the information store and to arrange, in one or more second chunks, a plurality of second blocks that represent changed blocks and added blocks of the block level data changes; and one or more media agent modules for storing the copy of the plurality of first blocks in the storage device according to the first mapping such that the copy of the plurality of first blocks stored in the storage device is in the same order as the plurality of first blocks stored in the information store.
