That's how I understood it too. But it will be difficult in our complex storage world to get the storage guys to create a consistency group. Also, what I'm looking for is a plugin that allows to, how Netapp call it, "quiece" the PostgreSQL cluster, i.e. does start/stop backup. I don't really trust the community plugin as it is so old and I'm not sure it gets any more development attention. For example, what about the API change (exclusive vs. non-exclusive)? Does it use the new API? Cheers, Paul
