Abstract
According to embodiments of the present disclosure, a method, device and computer program product for storage management are proposed. The method comprises: obtaining, in a first virtual storage device, a first portion storing a source file, the source file being used to update a target file; determining a second portion in the first virtual storage device, data stored in the second portion being changed relative to data stored in a second virtual storage device, the data stored in the second virtual storage device including the target file; determining a changed portion based on the first portion and the second portion, the changed portion indicating changed data of the source file relative to the target file; and updating the target file based on the changed portion. Therefore, the present solution can reduce data transmission and resource consumption.
