Data back-up system and method

Abstract

The invention is a data backup system and method, comprising VMM, I / O port, and mobile storage device matching the I / O port, where the VMM comprises at least a port monitor, and the mobile storage device comprises at least an operating system and at least a data backup unit as well as at least a data memory area. When the mobile storage device accesses to the I / O port, it guides and runs the operating system by the VMM and runs the data backup unit in the operating system, the data backup unit compares the backup file data in the data memory area with the file data in data area in need of backup, backups the file data in need of backup into the data memory area of the mobile storage device. And the invention also provides a bearing device for the mobile storage device. And the invention does not obviously influence computer performance but can safely backup the data in computer in time.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a data backup system and method. Background technique [0002] With the increasing number of computer users' various mobile smart devices, such as PCs and smart phones, their application scope is getting deeper and deeper into users' lives, and it has become more and more important. It has become a part of users' work and life. , Essential supplies for travel. [0003] The importance of mobile smart devices lies in the user's data files stored on these devices. As users use these devices longer and longer, more and more data are stored on these devices. Therefore, it is timely and convenient to update these data It has become more and more important to back up files to ensure data security. [0004] There are three categories of existing solutions: [0005] (1) Network backup solution. This method is usually very professional, and the equipment is very expensive. It is su...

Problems solved by technology

This method is usually very professional, and the equipment is very expensive. It is suitable for large and medium-sized enterprises and important government agencies. For small enterprises and individuals, due to their financial resources and personnel, as well as the small amount of data, it is not suitable for use.

[0006] (2) The stand-alone backup solution is suitable for personal use. Now the more common and simple method is to let the user connect a USB hard disk outside the computer, and then manually judge when the backup should be performed, and then judge which files are available. Change new files before backing up, which has too high requirements for users and is too difficult to operate; another method suitable for personal use is to develop a system unit on the operating system (OS) to help users regularly Perform backup, automatically determine which files have changed, and then back them up, but this method will have a significant impact on the performance of the operating system itself

[0007] At the same time, since the mobile device does not have a fixed installation location, it needs to be unplugged for safekeeping when not using the computer, and then taken out of the storage place to connect the mobile device when using the computer. Some mobile devices also require a separate power supply. It is very inconvenient for users to use

[0008] (3) The traditional redundant backup method, which installs two identical hard disks in a computer, and uses RAID technology to back up the content on the first hard disk to the second hard disk in real time and completely synchronously

[0009] The problems in the above methods cause users to feel very troublesome when backing up data files, so that they give up the active backup attempt intentionally or unintentionally in the end. When virus damage or hard disk damage occurs, important files without backup are lost Destroyed, causing irreparable loss to the user
