Transcript

  • 1. Data deduplication is a technique for reducing the amount of storage space an organization needs to save its data. What Is Data Deduplication Technology?
  • 2. Benefits of Data Deduplication It reduces the amount of disk or tape that organizations need to buy. It can reduce storage requirements up to 95 percent. It can reduce the amount of network bandwidth required for backup processes. It can speed up the backup and recovery process. It can save money and time.
  • 3. Types of Data Deduplication  Source Deduplication  Target Deduplication  Inline Deduplication  Post-Process Deduplication  Global Deduplication
  • 4.  Source deduplication is the removal of redundancies from data before transmission to the backup target.  It uses the client software for comparing new data blocks on the primary storage device with the previously backed up data blocks. Source Deduplication
  • 5. Target deduplication removes all the redundant data in the backup appliance most often on virtual tape library or a NAS device. It reduces the storage capacity required for backup data but does not reduces the amount of data sent across LAN or WAN. Target Deduplication
  • 6. Inline Deduplication  Inline deduplication is the removal of redundancies from data before or as it is being written to a backup device.  Inline deduplication reduces the amount of redundant data in an application and the capacity needed for the backup disk targets. Inline deduplication is the removal of redundancies from data before or as it is being written to a backup device.
  • 7. Post-Process Deduplication  Post-process deduplication writes the backup data into the disk cache before it starts the dedupe process.  It is mostly used in the backup applications, virtual tape libraries and the like, where reduction of backup time is required.
  • 8. Global Deduplication  Global data deduplication is a method of preventing redundant data when backing up data to multiple deduplication devices.  It removes all the possible backup data redundancies across multiple systems.
