Abstract: A data reduction method and apparatus are provided to improve data reduction performance. In the method a storage device obtains a first service type of first data stored in a first logical unit. The storage device processes the first data based on a first data reduction manner that matches the first service type. The storage device obtains a second service type of second data stored in a second logical unit. The second service type is different from the first service type. The storage device processes the second data based on a second data reduction manner that matches the second service type. The first data reduction manner includes data compression and/or data deduplication. The second data reduction manner includes data compression and/or data deduplication. The first data reduction manner is different from the second data reduction manner.
