Abstract
A method and system utilizing one or more data generating computing devices as default data warehouses in the event of a primary data warehouse failure are provided. A data warehouse provides an environment in which data from one or more data servers in one or more locations, or premises, is aggregated in a central database. In the event of a system failure, in which communication between the data warehouse and one or more servers is disrupted, a warehouse ticket file, stored on secure, distributed ticket servers, is used to identify and initialize at least one of the data servers as a failover data warehouse. Once communication between the premises and its primary data warehouse is restored, the data collected during the failover is transferred to the primary data warehouse and purged from the failover data warehouse.
