While Basho does provide a product including features that make whole-datacenter failure much less of a problem (by fully replicating to a cluster in another location) I will answer assuming you have only a single cluster. The timing doesn't have to be perfectly synchronized, but you should try to make it as close as is practical just so that you have a good way to judge what is contained in a given backup. If a storage (put) operation occurs in an interval between single-node backups, it will be present in the restored cluster when requested (and repopulated via read-repair) as long as it was in at least one of the nodes. -Justin _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
