Hello, Germain. You've already come across read-repair. Between that and hinted-handoff a great deal of passive anti-entropy is performed in a Riak cluster. As long as one doesn't use requests with R=N these mechanisms are generally sufficient.
We do have plans for a more "active" anti-entropy as well, so that if you know a given node has lost all of its data you can trigger a much more efficient and immediate complete repair from the replicas in other nodes. (without needing external backups) At this point, that is only a plan and not a developed feature, so if you don't perform backups then a trawling read-repair is your best bet in the case of a complete loss of a node. -Justin _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
