Embodiments of the present disclosure provide a method, an electronic device and a computer program product for data processing. In one embodiment, the method includes determining, at a first node in a network, one or more nodes in the network storing replicas of target data based on a hash value associated with the target data in the network. The method further includes executing replica maintenance for the target data, which includes determining the number of available nodes in the one or more nodes comparing a number of the available nodes with the predetermined number of replicas of the target data in the network and in response to the number of the available nodes being different than the predetermined number, changing storage distribution of replicas of the target data in the network.
