Abstract
The invention patent relates to a kind of novel based on the quick disaster recovery backup implementation method of snapshot realization, this method can install a disk management small routine on business host, disaster recovery backup equipment is divided to the hard disk volume to come, mirror image pattern is configured to by disk management small routine with local data volume, so that all write-in data meeting synchronous mirror or asynchronous mirroring to hard disk of local data volume are rolled up, simultaneously in the process used, disaster recovery backup equipment can temporally put preservation by the data that snapshot rolls up hard disk, it can be by indicator index to the retaining space of disaster recovery backup equipment physical volume to modification data.
Description
Technical field
The invention patent relates to computer disaster recovery backup fields.
Background technique
Disaster tolerant backup system refers in strange land relatively far apart, establishes two sets or the identical IT system of more set functions, mutually
Between can carry out state of health monitoring and function switch, when system stops working because of unexpected (such as fire, earthquake) at one,
Entire application system can be switched to another place, and the system function is allowed to continue to work normally.Disaster tolerance technology is system
One component part of High availability, disaster tolerance system more emphasize influence of the processing external environment to system, especially calamity
Influence of the difficult sexual behavior part to entire IT node provides the other system of node level and restores function.
Backup is the basis of disaster tolerance, refers to that operation error or the system failure occur for anti-locking system leads to loss of data, and
All or part of data acquisition system is copied to the process of other storage mediums from the hard disk or array of applied host machine.Traditional number
Cold standby is mainly carried out using internal or external magnetic tape station according to backup.But this mode can only prevent operation error et al.
For failure, and its recovery time is also very long.With the continuous development of technology, the magnanimity of data increases, and many enterprises start
Using network backup.Network backup generally by profession data storage management software in conjunction with corresponding hardware and storage equipment come
It realizes.
It can be related to multiple technologies when establishing disaster tolerant backup system, such as：SAN or NAS technology, Remote Switched Port Analyzer technology, base
In interconnection technique, the snapping technique etc. of the SAN of IP.Snapshot is quickly swept by data of the software to the disk subsystem to be backed up
It retouches, establishes the snapshot logical unit number LUN and snapshot cache for wanting Backup Data.In quick scanning, in backup procedure
The data block while rapid copy that will modify are into snapshot cache.Snapshot LUN is one group of pointer, it is directed toward snapshot cache
With data block constant in disk subsystem（In backup procedure）.While regular traffic carries out, realized using snapshot LUN
One of former data is completely backed up.It may use that family is in the case where regular traffic is unaffected（Refer mainly to disaster recovery backup
System）, the current online business datum of extract real-time.Its " backup window " can greatly increase the continuous of system business close to zero
Property, to realize that real 7 × 24 operating of system provides guarantee.
Patent of invention content
The invention patent relates to a kind of novel snapshots that is based on to realize quick disaster recovery backup implementation method, and this method can be in business host
Disaster recovery backup equipment is divided the hard disk volume to come and passes through disk pipe with local data volume by one disk management small routine of upper installation
Reason small routine is configured to mirror image pattern, so that all write-in data of local data volume understand synchronous mirror or asynchronous mirroring to hard disk
Volume, while in the process used, disaster recovery backup equipment can temporally put preservation by the data that snapshot rolls up hard disk, to modification number
According to retaining space of the indicator index to disaster recovery backup equipment physical volume can be pressed.
