Abstract: A data protection method implemented in a data protection device includes loading a data protection system in the data protection device, installing an application programming interface of the data protection system in the number of electronic devices, controlling the application programming interface to run in the background of the number of electronic devices, controlling the application programming interface running in each electronic device to monitor a storage device of the electronic device to determine whether data is transferred to the storage device, and outputting a prompt message when it is determined that data has been transferred to the storage of one of the electronic devices. The data protection device is communicatively coupled to the number of electronic devices.

Abstract: An energy saving method for a data center includes obtaining the operating conditions of a plurality of servers; determining whether the servers are in a first state according to the reading of conditions, and controlling the server in the first state to go into a second state. The disclosure also provides an energy saving device for a data center together with the method.
