REPLICATION CONTROL AMONG REDUNDANT DATA CENTERS

Systems, methods, and software for management of redundant data storage centers is provided herein. An exemplary method includes redundantly storing data records across the redundant data storage centers, with a first data storage center operating as a primary data storage center configured to respond to at least user input related to the data records. The method includes placing the first data storage center into an intermediate mode which comprises ceasing response to the user input by the first data storage center and executing pending operations related to previous user input received by the first data storage center, and designating the second data storage center as the primary data storage center configured to respond to at least further user input related to the data records.
