Abstract
Techniques are provided for deduplicating encrypted data. A method includes partitioning a data file into a plurality of data blocks. A block signature and a block key are calculated for one data block of the plurality of data blocks. The data block is encrypted using the block key. If the block signature for the encrypted data block matches the block signature for another encrypted data block, the encrypted data block is deleted and a link is created between a client and the other encrypted data block.
