Abstract

A computer system, a control method thereof and a recording medium storing a computer program thereof are provided to recover a program efficiently and be resistant to viruses, worms, and user error. The control method of computer system receives a user'"'"'s request for a recovery of a program which is installed in a first storage unit. A file system of a second storage unit is determined which stores therein a recovery program corresponding to the program for which the recovery is requested. The recovery program is read from the second storage unit with reference to the determined file system, and the program in the first storage unit is recovered by using the read recovery program.

Claims

1. A control method of a computer system, the method comprising:

receiving a request for performing a recovery operation of a particular program which is installed in a first storage unit;

determining a file system of a second storage unit which stores therein a recovery program corresponding to the particular program for which the recovery operation is requested;

reading the recovery program from the second storage unit with reference to the determined file system; and

recovering operation of the particular program installed in the first storage unit by executing the read recovery program.

2. The method according to claim 1, further comprising displaying a list of a plurality of programs installed in the first storage unit, wherein

the received request includes a selection of at least the particular program to be recovered from among the plurality of programs.

3. The method according to claim 1, wherein the determining the file system includes reading information from the second storage unit regarding the file system of the second storage unit.

4. The method according to claim 3, wherein the determining the file system includes copying to a main memory the information of the file system.

5. The method according to claim 1, further comprising storing the recovery program in the second storage unit.

6. The method according to claim 5, wherein the recovery program is stored prior to receiving the request for performing a recovery of the program stored in the first unit.

7. The method according to claim 5, wherein the recovery program is stored subsequent to receiving the request for performing a recovery of the program stored in the first unit.

8. The method according to claim 1, wherein access to the second storage unit comprises loading a function of a virtual file system component by the recovery program to request access to the determined file system stored in the second storage unit.

9. The method according to claim 8, wherein the virtual file system component accesses and provides the determined file system stored in the second storage unit to the recovery program.

10. The method according to claim 1, wherein the recovery program is stored as machine executable code on a detachable computer readable recording medium that is attached to the computer system to initiate a recovery operation.

17. A computer readable recording medium having recorded thereon a program executable by a computer for performing the method of claim 1.

11. A computer system, including:

a first storage unit having a predetermined program comprising machine executable code installed therein;

a second storage unit which stores a recovery program corresponding to a recovery operation for the predetermined program;

an input unit which receives an input; and

a controller which determines a file system of the second storage unit according to a received request with respect to the recovery of the predetermined program, reads the recovery program from the second storage unit with reference to the determined file system, and recovers operation of the predetermined program installed in the first storage unit by executing the read recovery program.

12. The computer system according to claim 11, further including a display unit, wherein the controller controls the display unit to show a list of a plurality of programs installed in the first storage unit, and selects at least one program to be recovered from among the plurality of programs.

13. The computer system according to claim 11, wherein the controller reads information from the second storage unit regarding a file system of the second storage unit.

14. The computer system according to claim 13, further including a main memory, wherein the controller copies to the main memory the information read from the file system.

15. The computer system according to claim 11, further including an installation unit which stores the recovery program in the second storage unit.

16. The computer system according to claim 11, wherein access to the second storage unit by the controller comprises loading a function of a virtual file system component to request access to the determined file system stored in the second storage unit.
