Data Deduplication: Get to Know About It

By Rupen Rajkarnikar

Data Deduplication is a specialized data compression technique for eliminating duplicate copies of repeating data or redundant data. Advantages:

  • Reduced storage capacity required for a given amount of data.
  • Ability to store significantly more data on given amount of disk.
  • Restore from disk rather than tape may improve ability to meet recovery time objective (RTO).
  • Network bandwidth savings (Client side deduplication).
  • Lower storage-management and energy costs resulting from reduced storage requirements. 
  • Deduplication consumes CPU cycle on the file.
