Abstract
This application provides a method that includes: obtaining an input data block; and processing the input data block by selecting one of alternatives: delta-compressing one or more target data blocks with the input data block used as a compression dictionary, where each target data block is one of processed data blocks; delta-compressing or deduplicating the input data block by using one of processed blocks as a dictionary or as a reference block for deduplication; independently compressing the input data block; or passing the input data block uncompressed for further processing.

-23. (canceled)
A method, comprising:
- obtaining an input data block;
- and
- processing the input data block according to one of the following methods:
- delta-compressing one or more target data blocks by using the input data block as a compression dictionary, wherein each target data block is one of processed data blocks;
- or
- delta-compressing the input data block by using one of processed data blocks as a compression dictionary.
An electronic device, comprising:
- at least one processor;
- and
- a memory storing instructions that are executable by the at least one processor, wherein execution of the instructions enables the electronic device to:
- obtain an input data block;
- and
- the input data block according to one of the following:
- delta-compress one or more target data blocks by using the input data block as a compression dictionary, wherein each of the one or more target data blocks is one of processed data blocks;
- or
- delta-compress the input data block by using one of processed data blocks as a compression dictionary.
