What is Deduplication ?
• Specialized data compression technique
• Eliminates coarse grained redundant data
• Improves storage (and bandwidth) utilization.

Source Based Data Deduplication
• Agent based deduplication
• Duplicates identified at source and removed from backup
• Saves bandwidth in addition to storage

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

Application Aware Deduplication
• Deduplicate logical information within data sets
• Works across applications
• 35-50% Better accuracy and storage/bandwidth savings
