Abstract:
1. A method for deduplicating data in a computer environment comprising: receiving a sequence of input data; identifying a header on the sequence of data indicating the sequence of input data is formatted for back-up such that an order of the sequence of back-up data is different than the order of the sequence of input data; generating a copy of the sequence of data; adding a space into the copy of the sequence of data that has been formatted for back-up; forming 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 sequence of the input data; performing deduplication using the new sequence of data; and upon receiving a read request, providing an other copy of the sequence of data, within the other copy of the sequence of data is the sequence of data in the same order as the back-up sequence of data and the back-up sequence of data is formatted by a Hierarchical Storage Management (HSM) application.
