Abstract

A file data restoring system and method of a computer operating system and software thereof are applied in the installation of an operating system into a client computer. Divide the file data corresponding to the operating system into data blocks according to an appointed data size. Generate a check code for each of the data blocks to form a sequence list of original check codes and a sequence list of target check codes. Compare the sequence list of original check codes with the sequence list of target check codes, after installing the operating system into the computer. If the comparison result is inconsistent, a restoring call information is sent out. The position of the inconsistent check code is acquired through the restoring call information and the comparison result. The original file data corresponding to the position of the check code is read and restored to a corresponding target file.

Claims

1. A file data restoring system of a computer operating system and software thereof, applied in an installation of an operating system and software thereof into a client computer, the system comprising:

a check code generating module, for dividing a plurality of file data corresponding to the operating system and software thereof into a plurality of data blocks respectively in accordance with an appointed data size, and generating a check code for each of the data blocks, so as to form a sequence list of original check codes corresponding to the original file data before the installation of the operating system and software thereof, and form a sequence list of target check codes corresponding to the target file data after the installation of the operating system and software thereof into the client computer;

a comparison module, for comparing records of a same file data in the sequence list of original check codes and the sequence list of target check codes, and sending out a restoring call information if a comparison result is inconsistent; and

a restoring module, for receiving the restoring call information, acquiring the position of the inconsistent check code according to the comparison result, and reading and restoring the original file data corresponding to the position of the inconsistent check code in the sequence list of original check codes to the target file data corresponding to the position of the inconsistent check code in the sequence list of target check codes.

2. The restoring system as claimed in claim 1, wherein, in accordance with the operating system and software thereof, the sequence list of original check codes and the sequence list of target check codes respectively comprise a full path name of the original file data with a sequence of original check codes corresponding to the original file data, and a full path name of the target file data with a sequence of target check codes corresponding to the target file data.

3. The restoring system as claimed in claim 2, wherein the comparison module compares the full path name of the original file data and the sequence of original check codes, with the full path name of the target file data and the sequence of target check codes.

4. The restoring system as claimed in claim 2, wherein the restoring module reads the corresponding restoring data from the original file data according to the full path name of the original/target file data, a start position of the data block corresponding to the inconsistent check code, and the appointed data size for dividing the file data.

5. The restoring system as claimed in claim 1, wherein the file data corresponding to the operating system and software thereof is divided in accordance with the appointed data size based on a formula as follows:

N=file size/appointed size+1,

wherein “

N”

is the number of the check codes obtained by dividing the file data, “

file size”

is the size of the file data, and “

appointed size”

is an appointed data size.

6. A file data restoring method of a computer operating system and software thereof, applied in an installation of an operating system and software thereof into a client computer, the method comprising:

dividing a plurality of file data corresponding to the operating system and software thereof into a plurality of data blocks respectively in accordance with an appointed data size;

generating a check code for each of the data blocks, so as to form a sequence list of original check codes corresponding to the original file data before the installation of the operating system and software thereof, and form a sequence list of target check codes corresponding to the target file data after the installation of operating system and software thereof into the client computer;

after the installation of the operating system and software thereof into the client computer, comparing records of a same file data in the sequence list of original check codes and the sequence list of target check codes, and sending a restoring call information if the comparison result is inconsistent;

acquiring the position of the inconsistent check code according to the restoring call information and the comparison result; and

reading and restoring the original file data corresponding to the position of the inconsistent check code in the sequence list of original check codes to the target file data corresponding to the position of the inconsistent check code in the sequence list of target check codes.

7. The restoring method as claimed in claim 6, wherein, in accordance with the operating system and software thereof, the sequence list of original check codes and the sequence list of target check codes respectively record a full path name of the original file data with a sequence of original check codes corresponding to the original file data, and a full path name of the target file data with a sequence of target check codes corresponding to the target file data.

8. The restoring method as claimed in claim 7, wherein the step of comparing the sequence list of original check codes with the sequence list of target check codes corresponding to the plurality of file data further comprises:

extracting two records of a same file in the plurality of file data from the sequence list of original check codes and the sequence list of target check codes respectively;

comparing the full path name of the original file data and the full path name of the target file data of the two records;

if consistent, comparing the sequence of original check codes and the sequence of target check codes of the two records.

9. The restoring method as claimed in claim 7, wherein the original file data corresponding to the position of the inconsistent check code is read according to the full path name of the original/target file data, a start position of the data block corresponding to the inconsistent check code, and the appointed data size for dividing the file data.

10. The restoring method as claimed in claim 6, wherein the file data corresponding to the operating system and software thereof is divided in accordance with the appointed data size based on a formula as follows:

N=file size/appointed size+1,

wherein “

N”

is the number of the check codes obtained by dividing the file data, “

file size”

is the size of the file data, and “

appointed size”

is an appointed data size.
