Abstract: This application discloses a disaster recovery deployment method, apparatus, and system, and relates to the field of network application technologies. The method includes: obtaining, by a master data center and a backup data center, disaster recovery control information; sending, by the master data center, the data corresponding to the service of the master data center to the at least one backup data center based on the disaster recovery control information; and deploying, by the backup data center, a disaster recovery resource for the master data center based on the disaster recovery control information, and backing up the received data. In other words, the master data center and the backup data center automatically back up resources and data based on the disaster recovery control information, and therefore, manual operation steps in a disaster recovery deployment process are simplified, and efficiency of disaster recovery deployment is improved.
