Description
Technical field
The present invention relates to the disaster tolerance data protections in data backup disaster tolerance field, are based on virtual platform more particularly, to one kind
With the application disaster tolerance system and method for ceph storage.
Background technique
With the fast development of computer and network technologies, nowadays most enterprises are all operated using computer certainly
Oneself core business.When computer system is by the irresistible natural calamity such as such as earthquake, floods, fire and computeritis
When the human factors such as poison, hardware and software failure, how to allow operation system to provide continual application service, have become enterprise face
The huge challenge and focus of attention faced.
Using disaster tolerance technology be current comparative maturity can guarantee operation system by it is various natural or it is artificial because
After element, it is still capable of providing the technology of uninterrupted application service.Cardinal principle are as follows: initial phase, to protected business system
System makees a complete copy, and data are written in corresponding virtual disk according to the call format of certain virtual platform；Afterwards
It is continuous that capture systems IO is continued using block grade CDP technology, and system IO is saved, while at set time intervals to void
Quasi- disk beats snapshot, and IO is written in snapshot；After disaster occurs for operation system, some snapshot and some IO time are selected
Point restores I/O data based on the snapshot, then by the virtual disk snapshot applications to newly-built virtual machine after recovery, and does phase
After the network configuration and certain system answered are repaired, any time dotted state before original operation system to disaster can be taken over,
To guarantee the continuity of operation system.
It is the computer system of various architectures how to be allowed to be taken in generation disaster using the difficult point of disaster tolerance technology
After application service can be rapidly provided.It is related to hardware compatibility between various architecture computer systems, net among these
A series of technological difficulties such as network configuration, system reparation.
Summary of the invention
It is flat based on virtualization that it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind
The application disaster tolerance system and method for platform and ceph storage.
