However, in a state where the password is not authenticated, no access can be made to the information for specifying the disk
Therefore, in the state where the password is not authenticated, the backup source and the backup destination cannot be associated

Embodiment Construction

[0021] figure 1 It is an overall view of an embodiment of the present invention.

[0022] exist figure 1 Among them, 1 is the host PC, 2 is the safe MO drive, 3 is the backup source safe MO disk, and 4 is the backup target safe MO disk.

[0023] Here, the secure MO, the secure medium, the secure disk, and the like mean media and the like that require password authentication to view stored data contents.

[0024] figure 2 It is the structural diagram of the secure MO disk.

[0025] exist figure 2 Among them, a secure MO disc is composed of a Security Media ID (hereinafter referred to as a Security Media ID), a password for authentication, and a normal data area. Usually the data area can be initialized (formatted) to read and write files from the PC. In order to write the normal data area on the secure MO disc, authentication must be performed using one of the four authentication passwords. Authentication passwords include the R / W password for reading and writing, the ...

Abstract

In the security media ID of a security MO disc, a unique ID of a backed-up disc is written in 64 bytes following the unique ID of the security media ID of the for-backup disc. When using a security MO disc, the security media ID can be seen before performing password authentication. Accordingly, by comparing the unique ID of the backed-up disc in the security media ID of the for-backup disc to a unique ID of another disc, it is possible to rapidly find the backed-up disc of the for-backup disc.

Description

technical field [0001] The invention relates to a backup method for data files and the like. technical background [0002] The backup process means copying all the files of the backup source disk to the backup target. The purpose of backup processing is to copy all files from the backup source to the backup destination. Therefore, the backup process may be a process of copying all files of the backup source to a specific folder of the backup target, or it may compare the backup source and the backup target, delete unnecessary files in the backup target, and copy the backup target. Differential backup processing for files not in [0003] In the case of performing a backup, the backup source disk must be associated with the backup target disk. As one method of realizing this correspondence, there is a method of writing information for specifying a backup destination into a backup source. A file in which a volume serial number, a volume label, or special information is writ...
