In view of secure protection problem of backup data,this paper designs a transparent encryption mechanism of backup data for disaster tolerance based on cascading file system.In this mechanism,it uses transparent encryption function based on virtual disk.When it reads data,it encrypts.When it writes data,it decrypts.Thus,it implements data disaster tolerance,and at the same time,it enhances the encryption protection of backup data.It protects the integrity and confidentiality of data.
