Claim:
A computer system comprising: at least one computer-readable medium; and at least one processor device in operable communication with the at least one computer-readable medium, the at least one processor being adapted to: receive a sequence of data, identify a header on the sequence of data indicating wherein the sequence of data is formatted for back-up such that an order of the sequence of data is different than the order of an input sequence of the data, generate a copy of the sequence of data, add a space into the copy of the sequence of data that has been formatted for back-up, form a new sequence of data from the copy of the sequence of data by inserting a first data block into the space so that the new sequence of data has a same order as the input sequence of the data, and perform deduplication using the new sequence of data; wherein the processor device is further adapted to, upon receiving a read request, provide an other copy of the sequence of the data, wherein the other copy of the sequence of the data is the sequence of data in the same order as the back-up sequence of the data, and wherein the back-up sequence of the data is formatted by a Hierarchical Storage Management (HSM) application.
