Disclosed embodiments provide techniques for multi-destination probabilistic data replication. Data transfer occurs over multiple time intervals. A data image to be transferred is divided into chunks. A manifest is created that lists each chunk and specifies an order, such that the data image can be reconstructed at its destination. The manifest is sent to the destination. The chunks may be sent to the destination, or to an aggregator site that then forwards the chunks to the destination. The chunks are reassembled at the destination based on information in the manifest. A probabilistic function is used to select an aggregator site based on an efficacy. The efficacy is based on a reward function that is computed for destinations for each time interval. A data transfer policy is periodically updated with a new efficacy value which is used for adjustment of the probabilistic function.
