Evolution Of Dedupe

  1. 1. 1Evolution of Data Deduplication (c) Druva Software 2010 February 11
  2. 2. 2Druva inSync – Overview and Advantage (c) Druva Software 2010 February 11What is Deduplication ?• Specialized data compression technique• Eliminates coarse grained redundant data• Improves storage (and bandwidth) utilization.
  3. 3. 3Druva inSync – Overview and Advantage (c) Druva Software 2010 February 11Why is it so Important ? PC Data Vs Available Bandwidth* 16000 12000 Axis Title 8000 Data (MB) 4000 Bandwidth (KB/Sec) 0 2000 2002 2004 2006 2008 2010• Data doubling every 18 months• Bandwidth grown only 10X last 10 years• Data duplication ▫ 80% across PCs ▫ 45% across servers
  4. 4. 4Druva inSync – Overview and Advantage (c) Druva Software 2010 February 11Data Reduction at Target• Duplicates removed at secondary storage to save space
  5. 5. 5Druva inSync – Overview and Advantage (c) Druva Software 2010 February 11Synchronous/Inline Target Data Reduction• Real-time/Synchronous duplicates removal• Improved storage capacity management• Slower than asynchronous deduplication
  6. 6. 6Druva inSync – Overview and Advantage (c) Druva Software 2010 February 11Source Based Data Deduplication• Agent based deduplication• Duplicates identified at source and removed from backup• Saves bandwidth in addition to storage
  7. 7. 7Druva inSync – Overview and Advantage (c) Druva Software 2010 February 11Global Source Based Data Deduplication• Duplicates compared against all sources• Big Leap in bandwidth and storage saving
  8. 8. 8 Druva inSync – Overview and Advantage (c) Druva Software 2010 February 11 Granularity: Block Based Deduplication• Granular block based comparison = Better Deduplication• Works well across simple application and similar data streams• Does not give very accurate results for complex apps e.g. Outlook or Exchange
  9. 9. 9Druva inSync – Overview and Advantage (c) Druva Software 2010 February 11Application Aware Deduplication• Deduplicate logical information within data sets• Works across applications• 35-50% Better accuracy and storage/bandwidth savings
  10. 10. 10 Druva inSync – Overview and Advantage (c) Druva Software 2010 February 11 Granularity: Extent of deduplicationFixed Blocks Variable Length Blocks App-Aware Block Length• Good for single application • Block size determined by • Block size determined by environments heuristics/ rolling- application data-structure checksum • Excellent for complex • Good for multiple data applications like streams Outlook, Exchange • Delivers dedupe across applications 1: 3X 1: 8X 1: 15X
  11. 11. 11 Druva inSync – Overview and Advantage (c) Druva Software 2010 February 11 Druva: App-Aware Deduplication• Source Based• Inline• Global• App-Aware block sizes• Supported applications – ▫ MS Outlook 2003/07/10 ▫ MS Office 2003/2007/10 ▫ PDFs ▫ JPEGs
  12. 12. 12Druva inSync – Overview and Advantage (c) Druva Software 2010 February 11Druva: Blackbird Storage Engine• Near CDP ▫ All incremental backups ▫ Instant search based restores Blackbird storage engine• High Performance (in memory) Hyper Cache Distributed Caching Hyper-Cache (coming soon) CDP + Dedupe File-system SSD Support Oracle DB for• Scalable meta-data ▫ Based on embedded Oracle DB ▫ 16TB, 200 parallel backups• Simple Software only solution SSD Simple 20 Mins deployment Disk Zero Maintenance
  13. 13. 13Druva inSync – Overview and Advantage (c) Druva Software 2010 February 11How Does Druva Compared to Others ? Druva , Veritas, EMC, CA, Comvault, IronMountain, Acronis, Atempo Source Based Dedupe EMC, Acronis, IronMountain, Druva , Veritas Global Deduplication EMC, IronMountain, Druva, Veritas Inline EMC Avamar, Druva inSync Sub-File EMC avamar, Druva inSync App- Aware Druva inSync
  14. 14. Druva inSync – Overview and AdvantageWhy Druva• A Fresh Approach Towards Backup ” Everything is there. I checked ▫ Unique Cutting-Edge Technology already… Ive been in this game a long time and I can honestly say that I have ▫ Simplified Management never seen something so simple. ▫ Enterprise Grade Support This, frankly, is brilliant. :-) ▫ Affordable Solutions Cheers !
