Ways to run deduplication

You can run deduplication on a volume, using a command. You can also create a schedule to run deduplication at specified times.

• Creating a deduplication schedule
  Deduplication operations run on enabled FlexVol volumes once a day at midnight by default. If you wish to run deduplication at another time, you can create a deduplication schedule.
• Running deduplication on existing data
  You can manually scan and eliminate duplicate blocks on an existing FlexVol volume.
• Running deduplication outside the preset schedule
  You might want to start deduplication outside the preset schedule, such as when your system is not busy, or when you want to test the impact of deduplication on a particular operation.
• Deduplication checkpoint feature
  The checkpoint feature is used to log the execution process of a deduplication operation periodically. When a deduplication operation is stopped for any reason (such as system halt, panic, reboot, or last deduplication operation failed or stopped) and a checkpoint data exists, the same deduplication process can resume from the latest checkpoint file.
