Problems solved by technology

The inventor found that NAS saves a lot of data of the operating system, but NAS does not support disaster recovery backup of data, so that the system using NAS will lose data when it encounters a failure, and the lost data cannot be recovered, resulting in a huge economic loss. loss

Abstract

The invention provides an NAS data backup disaster recovery method. The method comprises: in a main storage system and an auxiliary storage system which are associated, determining a main storage volume and an auxiliary storage volume corresponding to each other, establishing a remote replication relationship between the main storage volume and the auxiliary storage volume, closing an NAS functionof an NAS file system of the auxiliary storage volume, synchronizing data resources in the main storage volume to the auxiliary storage volume through the remote replication relationship, and completing data resource backup of the main storage volume in the auxiliary storage volume; when the main storage system breaks down, the auxiliary storage system works, stopping the remote copying relationbetween the main storage volume and the auxiliary storage volume, and starting the NAS function of the file system of the auxiliary storage volume in the auxiliary storage system. Data resources in the main storage system can be backed up, when the main storage system breaks down, the auxiliary storage system serves as a standby main storage system to work, then application data of a user continues to be stored, and disaster tolerance of the data resources of the main storage system is achieved.

Description

technical field [0001] The invention relates to the technical field of data disaster recovery, in particular to a NAS data backup disaster recovery method and device. Background technique [0002] Network Attached Storage (NAS) is a dedicated data storage server, also known as network storage; NAS is data-centric, completely separates storage devices from servers, and manages data centrally, thereby releasing system bandwidth and improving system performance . Compared with data storage servers, the cost of using NAS is far lower than the cost of using server storage, and the working efficiency of NAS is much higher than that of server storage. [0003] NAS supports multiple protocols, such as Network File System (Network File System, NFS), File Transfer Protocol (File Transfer Protocol, FTP) and Common Internet File System (Common Internet File System, CIFS), etc., and can support various types of operating system. The inventor found that NAS saves a lot of data of the o...
