Embodiment Construction

[0023] The present invention is based on a network environment as follows: including at least one client; a server;

[0024] The network connecting the server and the client.

[0025] This embodiment is implemented based on a hard disk protection card, and both the server and the client are equipped with hard disk protection cards.

[0026] The above-mentioned hard disk protection card completes the protection and restoration function of hard disk data. The specific principle is: at a certain moment, restore the point, establish a protection area, a mapping area, and use software and hardware to intercept all disk read and write requests. If the intercepted disk The write request will modify the valid data existing in the hard disk partition before the restoration point is established, that is, the data in the protected area. If it is the first write, then a corresponding size of mapping block should be allocated in the mapping area, and then the disk request will be redirecte...

Abstract

The invention discloses a method for synchronously updating computer hard disk data through a network, and particularly relates to a method for network cloning and incremental copying of hard disk data in a school computer room based on a hard disk protection card. The steps of the invention are as follows: For the initial data environment, network cloning is performed through the hard disk protection card to keep the hard disk data of the server and the client consistent. When the data environment of the server changes, it sends a restore command to the client. After the client restores, it receives the changed data sent by the server, and then The server and the client execute data merging at the same time, and the data merging becomes the basis for the next incremental copy. By using the method of the invention, the hard disk data environment of the school computer room and the Internet cafe can be changed at any time without redeployment, which saves time and improves efficiency.

Description

technical field [0001] The invention relates to a method for synchronously updating computer hard disk data through a network, in particular to a method for network cloning and incremental copying of hard disk data in a school computer room based on a hard disk protection card. Background technique [0002] The traditional way of maintaining the software environment in the computer room is to use hard disk restoration technology and network cloning technology. Taking the school computer room as an example, at the beginning of the new semester, the network administrator first needs to contact the teacher to determine the software environment of the personal computer (PC) in the computer room. The school computer room is generally oriented to the entire school, and the software environment is relatively complicated. Therefore, after the network administrator determines the computer room software environment for this semester, it still needs at least one week to establish this e...
