Terminal object classified backup and recovery methods based on cloud architecture

The invention provides terminal object classified backup and recovery methods based on a cloud architecture. During backup, a user interface is arranged at a terminal, and different backup classes are provided according to a preset display policy and can be selected by a user, wherein the different backup classes comprise different backup objects; and according to the backup classes and the backup objects which are selected by the user, terminal files which correspond to the backup objects are backed up on a cloud server at the terminal according to the preset display policy. During recovery, according to recovery classes and recovery objects which are selected by the user, files which are backed up by the terminal or the user and correspond to the backup objects are determined on the cloud server; and according to a preset recovery policy, corresponding recovery is performed at the terminal by using the backup files. By the invention, classified backup and recovery methods are provided, and backup and recovery speeds are improved.
