Abstract
Embodiments of the present disclosure relate to method, device and computer program product for data backup. In accordance with embodiments of the present disclosure, if a file is migrated between a first machine and a second machine, a data migration module compares the file with files already stored in the second machine, so as to only migrate modified and/or added data chunks in the files to the second machine. In this way, the performance of data migration has been improved.
