Disaster recovery storage system

Abstract

The invention discloses a disaster recovery and backup storage system and relates to a storage device. The system comprises a storage unit and a sever, wherein the storage unit combines network storage based on an Ethernet mode and optical storage based on a fiber channel (FC) protocol of optical fibers and provides a mass storage in a disk array, a network attached storage (NAS), an Internet protocol storage area network (IPSAN) and a fiber channel storage area network (FCSAN) are stored together in the mass storage, the mass storage comprises a data backup unit, a real-time data copying unit, a data mirror image unit and an application disaster recovery unit, the data backup unit achieves real-time backup and recovery of a server operation system, folders and a data base through a data backup technology, and the real-time data copying unit, the data mirror image unit and the application disaster recovery unit complete application program hot spare among servers and real-time synchronization of the data base by the aid of data duplication, data mirror images and an application and recovery technology. The system has the advantages that the mass storage integrates disaster recovery, backup and storage and meets the requirement of a disaster recovery and backup storage market.

Description

technical field [0001] The invention relates to a storage device, in particular to a disaster recovery storage system. Background technique [0002] Disaster backup (in a strict sense, it should be called disaster backup and recovery, referred to as disaster recovery), refers to the use of technology, management methods and related resources to ensure that key data, key data processing systems and key businesses can be restored after a disaster occurs. process. In this sense, the purpose of disaster recovery is to ensure the continuous operation of key businesses and reduce unplanned downtime. The disaster recovery system in the information field can be understood as a comprehensive system with the storage system as the basic support system, the network as the basic transmission means, the fault tolerance and backup software and hardware technology as the direct technical means, and the management technology as the important auxiliary means. [0003] At present, the indust...

Problems solved by technology

[0003] At present, the industry is facing several problems that restrict the development of disaster recovery storage systems: First, the two types of storage devices, network storage (IPSAN) and fiber optic storage (FCSAN), cannot be integrated into one device to meet the diverse selection requirements of connected servers ;Backup, disaster recovery, and storage software and hardware are purchased from different manufacturers, resulting in problems in product coupling; the localization of related foreign product software does not conform to domestic usage habits, and product service support fees are too high; this shows that the traditional complex software and hardware cooperation hinders The upgrade of IT applications, further system optimization and improvement of system maintenance efficiency, but separated software and hardware manufacturers can do nothing about it, they can only rely on lowering their product prices
