A system and method for “on-the-fly” de-duplication of data before storing the data in a storage system is provided. A data de-duplication module illustratively cooperates with protocol servers and a file system of a storage operating system executing on the storage system to implement the novel de-duplication technique. The de-duplication module illustratively generates a block store, an index file and a hash table on storage space provided by the storage system. The hash table is utilized for tracking fingerprints and locations of blocks within the block store. The index file is utilized for storing directory information identifying the contents of data containers stored on the storage system, while the block store is utilized to store raw data blocks that comprise the data containers.

When data is stored in many storage subsystems, metadata, such as a sequence number, is also generated and stored with the data. When the data is accessed, the metadata is checked to ensure that the desired data element has been accessed. In conventional storage subsystems, data elements, such as logical blocks, are stored sequentially in logical pages of each logical volume. Consequently, sequence numbers closely correlate with block positions within the physical pages and sequence number/position patterns tend to repeat frequently and access errors may not be detected. Algorithms are provided to calculate new, offset, physical block positions which reduce the close association of sequence numbers and physical positions, thereby reducing such aliasing. The algorithms incorporate the logical volume number, the logical page number, or both, in addition to the logical block number. As a result, detection of access errors becomes more likely.
