11. Data Deduplication Overview

12. Deduplication Architectures Storage Devices Server Client LAN SAN • Block Storage Device • Transparent to clients and servers • Reduces load on server and client • Adds load to storage device • No file or format awareness • Server side • Allows cross correlation of data among multiple clients • Adds load to server • Client side • Reduce load on server • Reduces bandwidth on LAN • Adds load to client • No cross correlation among multiple clients Protect More. Store Less.®

13. Data Deduplication Process (simplified) Assume a Data-Object or -Stream as Subject for deduplication Data Object / Stream Data Object is split in Chunks (fixed or variable size) For each Chunk an identity characteristic is determined • Duplicate chunks are identified • Identical Chunks are referenced with pointers, references. • Non-identical chunks or single instances are effectively stored • Compression may be performed in addition. A B C D A E F F D B A F A B C D E F Required Disk-Cache is reduced Identical Chunks Protect More. Store Less.®

14. Data Object / Stream Methods for Data Chunking File based One chunk is one file, most appropriate for file systems E.g. TSM Incremental Backup forever helps eliminate redundant data Fixed block Data object is split into fixed blocks Used by block storage devices Format Aware Understands explicit data formats and chunk data object according to format Example: breaking a PowerPoint deck into separate slides Format agnostic Chunking is based on algorithm that looks for logical breaks or similar elements within a data object Chunking method influences deduplication ratio Protect More. Store Less.®

15. A B C D A E F F D Method for Determining Duplicates A B C D E F Hashing Computes a hash (MD-5, SHA-256) for each data chunk Compares hash with all hash of existing data Identical hash means most likely identical data Potential (small) Risk of Hash Collisions: identical hash and non identical data Must be prevented through secondary comparison (additional metadata, second hash method, binary comparison) Binary Comparison Compares all bits of similar chunks Delta Differencing Computes a “delta” between two “similar” chunks of data where one chunk is the baseline and the second is the delta Since each delta is unique there is no possibility of collision To reconstruct the original chunk the delta(s) have to be re-applied to the baseline chunk Protect More. Store Less.®

16. In-Line Deduplication Deduplication VTL Backup Secondary Storage Primary Storage Data is deduplicated before it is actually stored Deduplication is performed as data flows into the secondary storage system • Advantages • Processes data once, eliminates additional post-processing tasks • Disadvantages • CPU intensive deduplication process can create performance bottleneck • One process per I/O stream Protect More. Store Less.®

17. Out-Band Deduplication (Post-Processing) Deduplication VTL Backup Secondary Storage Secondary Storage Primary Storage • Advantages • De-duplication CPU overhead no longer affects backup window • Supports multiple I/O streams • Potentially faster restore for first version (not deduplicated) • Disadvantages • Data is written, read and written – thus more I/O intensive • Deduplication window must be coordinated with backup window as it take typically longer than in-line processing • Requires larger secondary storage because first version is not deduplicated Data is first stored and deduplicated in the background Protect More.
