Referring to FIG. 1, a system restore including a mobile device according to a preferred embodiment of the present invention, and a multiple incremental backup method supporting a multi-operating system includes a PC or a mobile terminal driven by an operating system, The method comprising the steps of: (a) booting a PC or a portable terminal to start the operating system; (b) loading the PF driver, which is a recovery driver for performing data recovery of the PC or the portable terminal, with system privilege; (c) a point file (Point File) in which the PF driver records and stores the addition, change, and deletion of the storage of the PC or the portable terminal in a file unit in a free space of the PC or the portable terminal disk, , PF (PF region); (d) a start address and an end address of data added, changed, and deleted after the PC or the portable terminal is booted are recorded and stored in the PF area in the form of a read-only file in chronological order; (e) rebooting the user or switching the PC or portable terminal; (f) blocking access to the file by blocking the link of the start address and the end address of the addition, change, and deletion data stored in the PF, thereby recognizing that the system of the PC or the portable terminal is restored to the initial state Recovering the system to an initial state; .

That is, in the multi-incremental backup method supporting the system restoration and multi-operating system including the mobile device according to the preferred embodiment of the present invention, the PC or the portable terminal is booted and the operating system is started (step S110).

Here, the OS (Operating System) refers to an environment in which an application program can be efficiently executed by operating a PC or a portable terminal by operating a PC or a portable terminal and booting a kernel on the main memory, It refers to the basic software provided. The initial operating system monitors and controls the central processing unit (CPU), main memory, disk unit, and various input / output devices to operate normally, allocates and allocates hardware resources such as CPU time, memory space, The system management function of the system has been basic. However, nowadays, utility functions are added so that various application programs ranging from moving pictures and games can be performed, and the user interface is being changed into a more convenient graphical user interface (GUI). Task management and job management for managing file management for managing auxiliary storage devices such as hard disks, execution order and priority of application programs, security management for identification and confirmation of users, information exchange between computers The system management functions such as the network management that manages the management of the server are performed in a place where the user can not see. In addition, the operating system provides a processing function that can be commonly used among various application programs. Application programs can be concisely created by letting the operating system handle processing such as document processing, table calculation, reading and writing of files in a program, displaying characters on a screen, and printing.

Therefore, the preferred embodiment of the present invention is also capable of operating in a new disk formatting scheme other than the existing MBR (Master Boot Record) or FAT (File Allocation Table). For example, it can be applied to a disk format of GPT (GUID Partition Table) method.

Then, the PF driver is loaded as the system authority in the PC or the portable terminal (step S120).

At this time, the PF driver is a recovery driver that performs system recovery and restores the system using a point file (PF).

Then, the PF driver allocates the PF area to the free space of the PC or the portable terminal disk (step S130).

The PF area refers to a point file (PF) for recording and storing data in units of files when data changes, such as addition, change, or deletion of data, occurs on the storage while the user is using the PC or the portable terminal, Is generated.

Then, after the PC or the portable terminal is booted, the start address and end address of data added, changed, and deleted are recorded and stored in the PF area in the form of a read-only file in chronological order (step S140).

At this time, in step S140, the PF is operated by the PF driver with the system privilege, so that it can not be modified or deleted by the user or the administrator.

Then, the PC or the portable terminal is rebooted or the user is switched (step S150).

That is, a PC or a portable terminal used by a plurality of users such as a school or a PC room senses a reboot of the PC or the portable terminal when the user changes or detects that the user switching is selected.

Then, the link to the start address and end address of the addition, change, and deletion data stored in the PF generated in step S150 is disconnected to block access to the added, changed, or deleted data.

That is, since the system of the PC or the portable terminal can not access the added, changed, or deleted data, the changed or deleted data is restored to its original state, the added data is deleted, .

Referring to FIG. 3, a state where the PC or the portable terminal is booted is at time 0, and a state where a new file is added at time 0 is time 1. At this point in time 1, PF1 storing the start address and end address of the added new file is generated and stored in the PF area. Then, when the user finishes using the PC or the portable terminal and reboots or selects user switching, the user disconnects the link to the start address and the end address of the new file stored in the PF1 to block access from the system. That is, the system recognizes the present point of time as a point of time 0 when a new file is not added, not the point of time 1, and the physical location where the new file is stored is recognized as a free space again so that another file can be overwritten.

Referring to FIG. 2, a system restore method including a mobile device according to another exemplary embodiment of the present invention, and a multiple incremental backup method supporting multiple operating systems, may be performed by a PC or a mobile terminal driven by an operating system regardless of the type of the operating system A system recovery and backup method supporting a multi-operating system capable of restoring a user to a desired time point, the method comprising the steps of: (A) booting a PC or a portable terminal to start the operating system; (B) loading a PF driver, which is a recovery driver for performing data recovery of the PC or the portable terminal, with system privilege; (C) a point file (PF) in which the PF driver writes and stores the addition, change, and deletion of storage in the PC or the portable terminal in a file unit in a free space of the PC or the portable terminal disk, , PF (PF region); (D) If a specific time point is selected by an administrator or a user, if a PF is generated before the specific time point, a time point at which the PC or the portable terminal is booted The start and end addresses of the added, changed, and deleted data are recorded and stored in the PF area in a read-only file format; (E) generating a PF at a current time point when a recovery point is selected by the administrator or a user at a point of time when the PF is generated; (F) changing the current PF generated in the step (E) to the PF of the selected recovery point and executing the PF to return the system of the PC or the portable terminal to the recovery point state; .

That is, in the multi-incremental backup method supporting the system restoration and the multi-operating system according to another preferred embodiment of the present invention, the PC or the portable terminal is booted and the operating system is started (step S210).

Then, the PF driver is loaded as the system authority in the PC or the portable terminal (step S220).

At this time, the PF driver is a recovery driver that performs system recovery and restores the system using a point file (PF).

Then, the PF driver allocates the PF area to the free space of the PC or the portable terminal disk (step S230).

The PF area refers to a point file (PF) for recording and storing data in units of files when data changes, such as addition, change, or deletion of data, occurs on the storage while the user is using the PC or the portable terminal, Is generated.

Then, it is determined whether to generate the PF of the current time point (step S240). In general, a specific time point at which a PF is to be generated is selected by an administrator or a user.

If the PF is generated before the current time point at which the PF is generated in the step S240, the PF is added based on the point in time when the PC or the portable terminal is booted, The start and end addresses of the changed and deleted data are recorded and stored in the PF area in a read-only file format (step S250).

Then, the manager or the user selects a specific point in time to restore the PF (step S260).

Then, the PF at the present time point at which the specific point of time to be restored is selected (step S270).

Then, the current PF generated in the step S270 is changed to the PF of the specific time point to be restored selected in the step S260 and executed so that the system of the PC or the portable terminal returns to the state at the specific time point to be restored ( Step S280).

Referring to FIG. 3, if it is determined in step S260 that the first point of time at which the PF is generated is recovered, the PF of the current point in time 3 is generated in step S270. Then, in step S280, the PF at the time point 3 is changed to the PF at the time point 1 and executed, and the system returns to the state at the time point 1.

That is, the PF at the time point 3 stores the start address and end address of the file deleted at the time point 2, and the PF at the time point 1 stores the time 0, that is, the start address of the file added when the PC or the portable terminal is booted And end address.

In addition, by changing the PF of the time point 3 to the PF of the time point 1 according to the step S280, the system recognizes the state of the time point 1 so that the system can recognize that the PC or the portable terminal has been added Only the file is displayed, and the address information stored in the PF generated at the time point 2 and the time point 3 is ignored.

Accordingly, it is possible for the user to return the system to the desired point in time of the PF formed at the PC or the portable terminal in use.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
