A data processing method in a storage system is provided. The method includes: when the storage system is under a first load, performing an inline deduplication operation; and when the storage system is under a second load, directly storing a received second data block without performing the inline deduplication operation, where the first load is less than the second load.

Data deduplication method and apparatus, and computer program product

Adjustable deduplication method, apparatus, and computer program product

This application provides a data processing method and a storage device, and belongs to the field of storage technologies. In this application, the storage device performs deduplication and compression based on different granularities, deduplicates data based on a large granularity, and compresses the data based on a small granularity. Therefore, a limitation that a deduplication granularity and a compression granularity need to be the same is removed. A deduplication ratio decrease caused by an excessively large granularity and a compression ratio decrease caused by an excessively small granularity are avoided to some extent, to improve an overall reduction ratio of deduplication and compression.
