Disaster recovery backup is actually two concepts, the disaster recovery is to ensure that an information system can normally operate when a disaster occurs, and help an enterprise to achieve the goal of business continuity, and the backup is to deal with the problem of data loss caused by the disaster in the near future. Before the disaster recovery backup integrated product appears, the disaster recovery system and the backup system are independent. The ultimate goal of disaster recovery backup products is to help enterprises cope with 'soft' disasters such as human misoperation, software error, virus invasion and the like and 'hard' disasters such as hardware faults, natural disasters and the like.
The traditional solution is to set a backup server and a backup memory to respectively realize data backup and equipment disaster recovery to ensure normal operation when a fault occurs, and in the process, the data backup mainly adopts the combination of a remote mirroring technology and a snapshot technology to realize remote backup, namely, the data is backed up to a remote storage system through mirroring, and information in the remote storage system is backed up to a remote tape library and an optical disk library by using the snapshot technology. Mirroring is the information storage process that produces a mirrored view of the same data on two or more disks or disk subsystems, one called the master mirroring system and the other called the slave mirroring system. The storage system can be divided into local mirror and remote mirror according to the position of the master-slave mirror storage system. The remote mirroring is also called remote replication, is a core technology of disaster recovery backup, and is also a basis for maintaining remote data synchronization and realizing disaster recovery. The snapshot is to quickly scan the data of the disk subsystem to be backed up through software, and establish a snapshot logical unit number LUN and a snapshot cache of the data to be backed up. During fast scanning, data blocks to be modified in the backup process are simultaneously and fast copied into the snapshot cache.
