Description of the Invention: [Technical Field of the Invention] The present invention relates to a method for backing up and restoring computer data, and more particularly to a data pre-installation system for a mirror file and a method thereof. [Prior Art] Φ Seeing that digital information drives the development of business, but also becomes closely related to people's lives. Information such as online banking, digital cameras, the Internet, and customer information is an indispensable part of people's work and life. People have become more and more important about the importance of information. In order to enhance the security of data, various backup and recovery technologies have emerged, especially in the field of computer data backup and disaster recovery, in order to repair and reproduce the user data of the operating system. In the disaster recovery system, the backup and recovery of data is the basis and the key to the entire disaster recovery system. In terms of backup strategy, the known backup can be divided into full backup, incremental backup, differential backup, and cumulative backup strategy. A full backup is the copying of all files on a given computer or file system, regardless of whether it has been changed. Incremental backup is to back up only some of the data that was added or changed after the last backup. Incremental backups can be divided into multiple levels, each increment is derived from the up-and-down backup. The difference is only a part of the data that has changed after the last-time full backup. If there are only two backups, the incremental and differential backups are sampled. Accumulate backup _ f management manager 1303767 = accumulate the change of each time point ' and back up the changed value to the phase column, "backup mode can be restored to the pointing. = 曰 备 凡 凡 凡 全 全 全 全 全 全 全 全 全 全 全 全 全 全 全 全2 The material transfer backup method is to make the secret red tool of the job: the sun wheel needed for H and the mirror will be mirrored on the local hard disk, and then complete the image of the computer operating system or the domain. When a full backup of the slot case occurs, a large amount of = more ergo@ will be generated. 0 Bu,% she (4) test the hometown, implementation; ^ The longer, and more importantly, the longer the time to recover the information. If there is a method of making a full backup plus incremental backup, a full backup plus a difference, a full bet plus a cumulative backup, then in the case of _ constantly changing, the mirror will perform multiple mirroring operations, resulting in mirroring The increase in volume, and thus the management of the slot case, is inconvenient. In addition, when performing mirror image recovery, it may be necessary to restore data from a collection of multiple mirrored slots, in order to complete the complete system, and therefore not to be more versatile, and the recovery time is longer, resulting in lower recovery efficiency. . 1303767 SUMMARY OF THE INVENTION In order to solve the above-mentioned problems and disadvantages of the prior art, the object of the present invention is to provide a pre-installation secret and its branches, which are system-based data backup and recovery. In the data preview system and method of the mirror file disclosed in the present invention, the number of mirror files can be reduced, and the management of the mirror file can be facilitated.
