Abstract
A server system includes a primary server, at least one synchronous backup server, and at least one asynchronous backup server. The primary server includes a first processor. The at least one synchronous backup server, each includes a second processor configured to back up data of the primary server in a synchronous manner. The at least one asynchronous backup server, each includes a third processor configured to back up data of the primary server in an asynchronous manner. The first processor is configured to control each of one or more of the at least one asynchronous backup server to operate as a synchronous backup server when a number of the at least one synchronous backup server decreases due to a failure in at least one server included in the server system.
