Problems solved by technology

[0003] The application of Chinese patent publication number CN1601484 is a system and method for backing up disk data, and it must require the use of a specific data backup circuit module, and the data can only be connected to the data backup circuit module of the machine. Mirroring on multiple hard disks cannot achieve the purpose of network mirroring of data
The application of Chinese Patent Publication No. CN1637726 is a real-time dynamic protection method of hard disk data in Linux system, which cannot realize network mirroring of data, and can only be used for Linux operating system, so its application range has been greatly limited

Embodiment Construction

[0017] The specific method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] Fig. 1 is a working principle diagram of the present invention.

[0019] The present invention includes two parts, local and remote. The local and remote are connected through an IP network, wherein the local can include one or more local servers, and each local server can include one or more local disks or disk partitions that need to be mirrored. . There are one or more remote servers remotely, and each remote server can include one or more remote disks or disk partitions. A remote server can be shared by multiple local servers.

[0020] When the operating system writes data to the virtual disk, the driver writes data to the local disk and writes the same data to the remote disk at the same time, and then reports the result of this write operation to the operating system.

[0021] Figure 2 is the steps to create a virtual disk devic...

Abstract

A disk image method base on IP network, belongs to field of the data backup and high security system. The invention use the technologies of dummy disk equipment, simulated initiate end, connection of equipment software, simulated object end etc, when the operating system write the data to the equipment, the data is written in the local disk, and also sent and written in the corresponding place of the long-distance disk, to achieve the disk image method base on IP network..

Description

1. Technical field [0001] The invention proposes an IP network-based disk mirroring method, which belongs to the field of data backup and high reliability systems, and realizes disk mirroring on two computers connected through the IP network. 2. Background technology [0002] With the continuous growth of network storage and the continuous improvement of people's requirements for the security of stored information, high-reliability systems have become a topic of increasing concern. The mirror technology is the key to the success of the entire highly reliable system. At present, relatively mature mirroring technologies include local mirroring and remote mirroring. Among them, the mirroring distance of local mirroring is greatly limited, which cannot meet the remote protection requirements of some core data. Remote mirroring technologies include SAN (storage area network, storage area network), NAS (network area storage, network attached storage), etc., but they all have the...
