A coordination point for assigning clients to remote backup storages includes a persistent storage and a processor. The persistent storage stores gateway pool cache capacities of the remote backup storages. The processor obtains a data storage request for data from a client of the clients; obtains an indirect cache estimate for servicing the data storage request; selects a remote backup storage of the remote backup storages based on the obtained indirect cache estimate using the gateway pool cache capacities; and assign the selected remote backup storage to service the data storage request. The selected remote backup storage has a higher client load at a time selection than a second client load of a second remote backup storage of the remote backup storages.
