摘要： A secondary location of a network acts as a recovery network for a primary location of the service. The secondary location is maintained in a warm state that is configured to replace the primary location in a case of a failover. During normal operation, the primary location actively services user load and performs backups that include full backups, incremental backups and transaction logs that are automatically replicated to the secondary location. Information is stored (e.g. time, retry count) that may be used to assist in determining when the backups are restored correctly at the secondary location. The backups are restored and the transaction logs are replayed at the secondary location to reflect changes (content and administrative) that are made to the primary location. After failover to the secondary location, the secondary location becomes the primary location and begins to actively service the user load.
