OPERATING SYSTEM RESTORATION USING REMOTE BACKUP SYSTEM AND LOCAL SYSTEM RESTORE FUNCTION

摘要

A computer performs a backup operation copying user files and system files to a separate backup system for persistent storage. The system files include restore-point files from a system area of a source system storage device, the restore-point files created by the computer's operating system and being copies of constituent files of the operating system at a point in time. In a subsequent restoration operation, the computer is operated in a limited-functionality recovery mode including (a) executing a recovery program from a recovery storage device to restore the restore-point files from the recovery storage device to a system area of a target system storage device, and (b) executing a system restore function with selected restored restore-point files to restore the operating system. Subsequently, the computer is operated in a full-functionality operating mode including (a) executing the restored operating system, and (b) executing the recovery program to restore the user files from the recovery storage device to the computer.
