Problems solved by technology

The disadvantage of this method is that since the data to be backed up includes a large amount of user data, the backup of a large computer system usually takes several hours to complete, and the system backup is usually not performed every day
Moreover, the restored data is the data before the backup, and the new data generated by the user after the backup cannot be restored. In addition, it also takes a lot of time to restore the backup data, which brings certain troubles to the restored work.

Embodiment Construction

[0009] A method for preventing and solving data loss, including a disk backup method and a disk restoration method, the above backup and restoration method involves the backup and restoration of disk system information, the system information backed up by the disk includes disk MBR information, disk EBR information, each DBR Information, system data of various partitions. The system data of various partitions varies according to the partition type. The present invention will be described in detail below in conjunction with the accompanying drawings.

[0010] see figure 1 As shown, the disk backup method at least includes the following steps:

[0011] Step 1 reads the MBR information and writes it into the backup file;

[0012] Step II analyzes the partition positioning information therein, and points the partition entry analysis pointer to the first partition entry, and if the data in the partition entry is illegal or all empty, go to step VII;

[0013] Step III judges whe...

Abstract

This invention relates to a method for information back up and resumption including a disk back up method and a disk recovery method, in which, the system information backed up in a disk includes information of a primary leading fan region, information of an expanded primary leading fan region, the leading fan region information of branches and system data of the branches, in which, the system data of the branch regions are different based on the different kinds of the branches, which provides a method for providing disk backup and recover when the information of a leading region is destructed.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a method for backing up and restoring information. Background technique [0002] The increasing use of electronic data creates requirements for information maintenance and protection against accidental loss. As a commonly used external storage for computers, disks often face situations such as user misuse and computer virus infection. Therefore, it is particularly important to back up disk data so that some important data can be restored when necessary. [0003] In the disk data backup and recovery methods in the prior art, the data backed up generally includes system data and user data on the disk. The disadvantage of this method is that, because the data to be backed up includes a large amount of user data, it usually takes several hours to complete the backup of the large computer system, and the system backup is usually not carried out every day. And the restored data i...
