Abstract: The present disclosure relates to a method, device and computer program product for managing data placement. In the method for managing data placement, in response to receiving a backup request for backing up raw data, the raw data is stored in a first storage system so as to form a raw copy. Metadata corresponding to the raw data is obtained, the metadata comprising abstract information of the raw data. The metadata is stored in a blockchain system in a second storage system so as to form a metadata copy, the first storage system and the second storage system being independent storage systems provided by a first vendor and a second vendor respectively. The raw data is managed by using the raw copy and the metadata copy. In the present disclosure, the raw copy and the metadata copy are stored to different storage systems, so that it may be judged whether a copy has been tampered with, and further higher security may be provided.
