description Data storage is presented herein. For instance, an example method includes determining, in response to that a predicted backup time of a target object is longer than a threshold time, a target server and a source storage node which are corresponding to the target object, wherein the target server stores objects, and the target server is associated with the source storage node. storage nodes whose predicted backup time for an object is shorter than a corresponding threshold time are determined as candidate storage nodes. A target storage node is determined based on different pieces of performance of the candidate storage nodes. A storage position of the target object is adjusted from the source storage node to the target storage node. Consequently, position distribution of servers on a storage node cluster can be adjusted so as to avoid a synchronization overtime event as much as possible.
