Abstract
Techniques provide for data deduplication. Such techniques involve: allocating a storage area in a storage device, the storage area including a first storage segment for storing an incompressible data block and a second storage segment for storing a compressed data block, a first size of the first storage segment being greater than a second size of the second storage segment; in response to receiving a write request, determining whether data block to which the write request is related is compressible; in response to determining that the data block is incompressible, adding header information to the data block to generate a first data segment of the first size; and storing the first data segment in the first storage segment through a deduplication operation. Accordingly, such techniques can increase the flexibility and efficiency of data deduplication.
