Abstract
An existing primary data copy can be maintained on an existing primary front end server node. One or more existing secondary data copies can be maintained on one or more existing secondary front end server nodes to minor the existing primary data copy (such as by making synchronous changes to the secondary data copies). One or more existing backup data copies can be maintained on an existing backend server node to mirror the existing primary data copy (such as by making asynchronous changes to the one or more backup data copies). The existing backend server node can be accessible by one or more of the front end nodes. In response to detecting a failure of the existing primary data copy, one of the one or more secondary data copies can be designated as a new primary data copy in place of the existing primary data copy.
