Abstract

A maintenance system in which a user work made during a maintenance work is not lost is provided. Specifically, a user computing machine includes: a user data determination section determining, in a case that a name of a file received from a software update service is the same as a name of a file included in a VM that a user uses, whether the file included in the VM that the user uses is data created by the user; and a VM merge section copying a file except user data into the VM that the user uses in the received files by calling the user data determination section.

Claims

1. A maintenance system comprising:

a data acquisition section configured to receive a file from a software update service which updates a file of software used in a virtual machine in place of a user;

a user data determination section configured to determine, in a case that a name of the received file is the same as a name of a file of software used in the virtual machine, whether the file of software used in the virtual machine is data created by the user; and

a copy section configured to copy a file determined that the file is not data created by the user in the received files into the virtual machine.

2. The maintenance system according to claim 1, wherein if files of software used in the virtual machine include a file whose name is the same as a file to be copied, the copy section overwrites the file to be copied into the file, whose name is the same, of software used in the virtual machine;

and if files of software used in the virtual machine does not include a file whose name is the same as a file to be copied, the copy section adds the file to be copied to the virtual machine.

3. The maintenance system according to claim 1, wherein the copy section determines, with reference to a list for defining a setting file, whether or not a file to be copied is a setting file;

and if the file to be copied is determined to be a setting file, the copy section copies the file to be copied into the virtual machine.

4. The maintenance system according to claim 1, wherein the copy section compares a version of the file received from the software update service and a version of a file of software used in the virtual machine;

determines whether or not the version of the file received from the software update service is newer than the version of the file of software used in the virtual machine; and

copies a file whose version is determined to be newer than the version of the file of software used in the virtual machine in files received from the software update service into the virtual machine.

5. The maintenance system according to claim 1, wherein said user data determination section determines, with reference to a list including identification information which indicates at least one of file names and extensions, a file corresponding to identification information written in said list as data created by said user in files of software used in said virtual machine.

6. The maintenance system according to claim 1, wherein said user data determination section searches whether or not a file of software used in said virtual machine includes personal information;

and determines a file including said personal information as data created by said user.

7. The maintenance system according to claim 1, wherein said user data determination section determines, with reference to a list of files of said virtual machine and a virtual machine used in said software update service, a non common file between said virtual machine and a virtual machine used in said software update service as data created by said user.

8. The maintenance system according to claim 1, wherein said user data determination section monitors a start of an application and file reading;

and determines a file which is not read by said application in a period from a start to completion of said application as data created by said user.

9. The maintenance system according to claim 1, wherein said user data determination section monitors a start of an application and a directory of a file read by said application;

and determines, if said directory is changed, a file read after said directory is changed as data created by said user.

10. A maintenance method, which is executed by a computing machine used by a user, comprising:

receiving a file from a software update service which updates a file of software used in a virtual machine in place of a user;

determining, in a case that a name of the received file is the same as a name of a file of software used in the virtual machine, whether the file of software used in the virtual machine is data created by the user; and

copying a file determined that the file is not data created by the user in the received files into the virtual machine.

11. The maintenance method according to claim 10, further comprising:

overwriting, if files of software used in the virtual machine include a file whose name is the same as a file to be copied, the file to be copied into the file, whose name is the same, of software used in the virtual machine; and

adding, whereas if files of software used in the virtual machine does not include a file whose name is the same as a file to be copied, the file to be copied to the virtual machine.

12. The maintenance method according to claim 10, further comprising:

determining, with reference to a list for defining a setting file, whether or not a file to be copied is a setting file; and

copying, if the file to be copied is determined to be a setting file, the file to be copied into the virtual machine.

13. The maintenance method according to claim 10, further comprising:

comparing a version of the file received from the software update service and a version of a file of software used in the virtual machine;

determining whether or not the version of the file received from the software update service is newer than the version of the file of software used in the virtual machine; and

copying a file whose version is determined to be newer than the version of the file of software used in the virtual machine in files received from the software update service into the virtual machine.

14. The maintenance method according to claim 10, further comprising:

determining, with reference to a list including identification information which indicates at least one of file names and extensions, a file corresponding to identification information written in said list as data created by said user in files of software used in said virtual machine.

15. The maintenance method according to claim 10, further comprising:

searching whether or not a file of software used in said virtual machine includes personal information; and

determining a file including said personal information as data created by said user.

16. The maintenance method according to claim 10, further comprising:

determining, with reference to a list of files of said virtual machine and a virtual machine used in said software update service, a non common file between said virtual machine and a virtual machine used in said software update service as data created by said user.

17. The maintenance method according to claim 10, further comprising:

monitoring a start of an application and file reading; and

determines a file which is not read by said application in a period from a start to completion of said application as data created by said user.

18. The maintenance method according to claim 10, further comprising:

monitoring a start of an application and a directory of a file read by said application; and
