Embodiment Construction

[0029] The mirror image recovery speed of the existing mirror image recovery method is relatively slow, and the embodiment of the present invention provides a mirror image recovery method, which can improve the mirror image recovery speed.

[0030] Please refer to FIG. 2 , which is a schematic diagram of an application environment of the image recovery method according to the embodiment of the present invention.

[0031] One of the networking situations of asynchronous remote mirroring is described in Figure 2, which includes two application hosts, which are interconnected through a WAN (Wide Area Network) or a LAN (Local Area Network), and cluster software is installed on the two application hosts And constitute a highly available test HA (High Availability) environment. The services running on the application host can be enterprise-level applications such as database services, mail services, and file services. The networking also includes two storage devices, namely the pri...

Abstract

This invention discloses an image resuming method including: obtaining position registration of updated data of a first storage device registering the updated states of data at different positions, comparing the position registration of the second device with that of the first to get different data positions of them then copying data corresponding to the positions to the first device. This invention also provides a storage device, which mainly compares the position registration for updating data recorded by a registration unit with that of another storage device obtained by the obtaining unit to get the positions itself and another storage device and copies the data corresponding to these positions onto another storage device. This invention also provides a network system.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a mirror image restoration method, a storage device and a network system. Background technique [0002] Disaster recovery technology is becoming more and more important at present. Remote mirroring is one of the technologies for establishing a disaster recovery backup system. Mirroring is the information storage process that produces mirrored views of the same data on two or more storage devices. Remote mirroring can be divided into synchronous remote mirroring and asynchronous remote mirroring. [0003] Synchronous remote mirroring (synchronous replication technology) means that every time the application host of the master station sends a write request, it must wait for the data to be completely written into the master volume of the master storage device and the slave volume of the slave storage device before continuing to execute. Synchronous remote mirroring is g...
