Abstract
The invention aims at achieving a switching technique based on disaster recovery in business. When irresistible factors such as earthquake, fire disaster happen in a production center and lead to the condition that the business cannot keep going, by using the switching technique, the business in the production center is taken over, services are continued to provided for the outwards, the problem that the business is interrupted is well solved, and unnecessary damage is reduced.
Description
Technical field
The present invention relates to a kind of handoff technique based on disaster tolerance, belong to Computer Data Security process field.
Background technology
Along with the continuous expansion of enterprise operation system, the continuous increase of quantity of information, simple data backup can not meet the demand of enterprise already, and the adapter of business becomes the best solution that numerous enterprises is pursued already, exempt the danger of economic loss or even the life causing service disconnection to be brought because of the disaster such as earthquake, fire, such as: financial industry, medical industry.
That what for disaster tolerance is for IT, one that provides for the computer information system exactly environment dealing with various disaster.When computer system is when suffering the human-made disasters such as irresistible natural disaster and computer crime, computer virus, power down, network/communication failure, hardware/software mistake and manual operation mistake, disaster tolerance system will ensure the security (data disaster tolerance) of user data, even, a more perfect disaster tolerance system, can also provide continual application service (application disaster tolerance).Can say, disaster tolerance system is the highest level of data backup memory.
Disaster tolerance system is divided into again data disaster tolerance and application disaster tolerance.
So-called data disaster tolerance, just refers to the data system setting up a strange land, and to be that of local crucial application data is available copy this system.When disaster appears in local data and whole application system, system at least preserves the data of a available key business in strange land.These data can be and the copying completely in real time of local production data, can than local data backwardness slightly, but must be also available.
So-called application disaster tolerance, is on the basis of data disaster tolerance, sets up the back-up application system (can be backup each other) suitable with local production system of complete set in strange land.It is relatively complicated for setting up such system, not only needs a available data Replica, also will have and comprise the resource such as network, main frame, application, even IP, and the good coordination between each resource.Main technology comprises load balancing, Clustering.Data disaster tolerance is the technology of application disaster tolerance, and application disaster tolerance is the target of data disaster tolerance.
Weigh two technical indicator: RPO (Recovery Point0bjective) of disaster tolerance system: i.e. date restoring point target, mainly refers to the patient amount of data lost of operation system.RTO Recovery Time0bjective): namely release time target, mainly refer to patient business stop the maximum duration of service, namely occur to cycle shortest time required for operation system Resume service function from disaster.RPO for be loss of data, and RTO for be loss of service, the two does not have inevitable relevance.The determination of RTO and RPO must be determined according to different business demands after carrying out venture analysis and business impact analysis.For the same business of different enterprise, the demand of RTO and RPO also can be different.Certainly, present most enterprise data RPO, RTO that will reach is more better close to zero.
Based on this, use handoff technique, the service take-over of the production center can well be come, thus reduce unnecessary loss.
Summary of the invention
The present invention seeks to the handoff technique in order to realize based on disaster tolerance in business.When the production center run into earthquake, fire etc. can not resist factor and the business caused cannot continue when, use handoff technique, the service take-over of the production center is come, continue externally to provide service, well solve the problem of service disconnection, decrease unnecessary loss.
Technical scheme of the present invention so realizes, and based on the handoff technique of disaster tolerance, described method comprises the steps:
Production center data change, and real-time synchronization, to Disaster Preparation Center, ensures the consistance of two places data.
Send normal job information to Disaster Preparation Center, two places keep real-time Communication for Power.
When production center data suffer that destruction causes business to continue, Disaster Preparation Center just can receive the information of normal work.
Disaster Preparation Center can send signal to the production center, awaits a response.
So do not respond if appointed, Disaster Preparation Center just can start takeover mode, is taken over by the IP of the production center, thus takes over external business, and business is proceeded.

Embodiment
The present invention seeks to the handoff technique in order to realize based on disaster tolerance in business.When the production center run into earthquake, fire etc. can not resist factor and the business caused cannot continue when, use handoff technique, the service take-over of the production center is come, continue externally to provide service, well solve the problem of service disconnection, decrease unnecessary loss.
Described method comprises the steps:
Production center data change, and real-time synchronization, to Disaster Preparation Center, ensures the consistance of two places data.
Send normal job information to Disaster Preparation Center, two places keep real-time Communication for Power.
When production center data suffer that destruction causes business to continue, Disaster Preparation Center just can receive the information of normal work.
Disaster Preparation Center can send signal to the production center, awaits a response.
So do not respond if appointed, Disaster Preparation Center just can start takeover mode, is taken over by the IP of the production center, thus takes over external business, and business is proceeded.
As Fig. 1, the data syn-chronization first data of the production center produced at any time, to Disaster Preparation Center, ensures data syn-chronization, reaches the consistance of data.
As Fig. 2, when the production center is impaired, cannot send normal job information, Disaster Preparation Center just can adapter IP, thus the business of the adapter production center, ensure the continuity of business, reach the switching of disaster tolerance.
Claims (3)
1., based on the handoff technique of disaster tolerance, described method comprises the steps:
Production center data change, and real-time synchronization, to Disaster Preparation Center, ensures the consistance of two places data.
Send normal job information to Disaster Preparation Center, two places keep real-time Communication for Power.
When production center data suffer that destruction causes business to continue, Disaster Preparation Center just can receive the information of normal work.
Disaster Preparation Center can send signal to the production center, awaits a response.
So do not respond if appointed, Disaster Preparation Center just can start takeover mode, is taken over by the IP of the production center, thus takes over external business, and business is proceeded.
2. the production center as claimed in claim 1 data change, and real-time synchronization, to Disaster Preparation Center, ensures the consistance of two places data.
3., as described in claim 1 when production center corrupted data, cannot send normal job information, Disaster Preparation Center just can start takeover mode, is taken over by the IP of the production center.
