Multiple secondary storages feature has been added since some time now. This would help in scaling the secondary storages for snapshots. The private templates are copied to one of the secondary storages and public to all of them for higher availability.All the public templates will be replicated to all the secondary storage for redundancy but private templates and uploaded volumes should would be kept in one of the randomly chosen secondary storage. Snapshots will be are randomly copied to one of the secondary storage (the chain of incremental snapshots are kept on the same secondary storage.) Currently these algorithms are hardcoded and there is no way to tweak it. In case you need flexibility please open an enhancement for the same. During template sync the consistency is again checked and download triggered for templates keeping in mind the algorithm above.
