Data recovery method and cloud server

The invention provides a data recovery method and a cloud server. The data recovery method is applied to the cloud server; the cloud server is connected with temperature-regulating equipment. The data recovery method comprises the following steps: recording a changing operation for changing data generated in the running process of the temperature-regulating equipment, wherein a record comprises data changed by the changing operation; receiving a data recovery request, wherein the data recovery request is used for recovering data changed by performing a mistaken changing operation on the temperature-regulating equipment; analyzing the data recovery request, and acquiring a changing operation which is carried in the data recovery request and marked as a mistaken change; searching the changing operation marked as the mistaken change from the record, and acquiring data changed by the changing operation marked as the mistaken change; sending the data changed by the changing operation marked as the mistaken change to the temperature-regulating equipment.
