Automatic backup device, automatic backup method, and recording medium
First Claim
1. An automatic backup device comprising:
- a history information acquisition unit that acquires history information containing a time of a change in setting on a backup target device and a content of the change associated with each other;
a restoration request acquisition unit that acquires a restoration request containing a time intended for restoration of the backup target device;
a restoration information generation unit that generates restoration information for restoring the backup target device based on the time contained in the restoration request by using the history information acquired by the history information acquisition unit; and
a restoration information transmission unit that transmits the restoration information generated by the restoration information generation unit to the backup target device,wherein the history information includes first change history and second change history,wherein, when there is a contradiction between the first change history and the second change history, the restoration information generation unit further executes processing of generating third change history for resolving the contradiction, the third change history being generated by interpolating between the first change history and the second change history, andwherein the third change history resolves the contradiction by providing values that are intermediate to the first change history and the second change history.

Abstract
To allow restoration of a backup target device more properly. An automatic backup device comprises: a history information acquisition unit that acquires history information containing a time of a change in setting on a backup target device and a content of the change associated with each other; a restoration request acquisition unit that acquires a restoration request containing a time intended for restoration of the backup target device; a restoration information generation unit that generates restoration information for restoring the backup target device based on the time contained in the restoration request by using the history information acquired by the history information acquisition unit; and a restoration information transmission unit that transmits the restoration information generated by the restoration information generation unit to the backup target device.

11. An automatic backup method executed by a computer, the method comprising:
-
a history information acquisition step of acquiring history information containing a time of a change in setting on a backup target device and a content of the change associated with each other; a restoration request acquisition step of acquiring a restoration request containing a time intended for restoration of the backup target device; a restoration information generation step of generating restoration information for restoring the backup target device based on the time contained in the restoration request by using the history information acquired by the history information acquisition step; and a restoration information transmission step of transmitting the restoration information generated by the restoration information generation step to the backup target device, wherein the history information includes first change history and second change history, wherein, when there is a contradiction between the first change history and the second change history, the restoration information generation step further comprises a step of generating third change history for resolving the contradiction, the third change history being generated by interpolating between the first change history and the second change history, and wherein the third change history resolves the contradiction by providing values that are intermediate to the first change history and the second change history. - View Dependent Claims (12)

13. A non-transitory computer-readable recording medium storing a program that causes a computer to function as:
-
a history information acquisition unit that acquires history information containing a time of a change in setting on a backup target device and a content of the change associated with each other; a restoration request acquisition unit that acquires a restoration request containing a time intended for restoration of the backup target device; a restoration information generation unit that generates restoration information for restoring the backup target device based on the time contained in the restoration request by using the history information acquired by the history information acquisition function; and a restoration information transmission unit that transmits the restoration information generated by the restoration information generation function to the backup target device, wherein the history information includes first change history and second change history, wherein, when there is a contradiction between the first change history and the second change history, the restoration information generation unit further executes processing of generating third change history for resolving the contradiction, the third change history being generated by interpolating between the first change history and the second change history, and wherein the third change history resolves the contradiction by providing values that are intermediate to the first change history and the second change history. - View Dependent Claims (14)
