Terminal backup object sharing and recovery method based on cloud architecture

The invention provides a terminal backup object sharing and recovery method based on a cloud architecture. The method comprises the following steps of: presetting a file database at a cloud server, wherein the file database stores different terminal files and uniqueness characteristic information of the files; recording the backup data sent by the terminal/the user and subjected to backup, by the cloud server, wherein the backup data comprise the uniqueness characteristic information of the backed up terminal object; determining the corresponding relation between the terminal object backed up by the terminal/the user and the terminal file stored in the file database according to the uniqueness characteristic information of the backup; generating an access path for the backup data of the terminal/the user by the cloud server; and when the terminal/the user makes an access request to the cloud server via the access path, determining the corresponding terminal files in the file database according to the uniqueness characteristic information contained in the backup data, and executing recovery at the terminal/the user side based on the terminal files. With the method, backup data sharing is realized, and speed of backup recovery is improved.
