Embodiment one
Below in conjunction with Fig. 1, Fig. 1 is a kind of process of virtual machine business quick recovery method provided by the embodiments of the present application
Figure, specifically includes the following steps:
S101: increase data communication component for the Backup Data of fault virtual machine, obtaining can backup communication data；
This step is intended to so that the Backup Data that originally may do not have accessed ability has as where initial data
The same ability of virtual machine image, can access of the backup communication data realization to data with existing in order to be directly based upon.
Backup Data inherently causes initial data that can not access a kind of solution that phenomenon provides because abnormal in order to prevent
Scheme, it is generally the case that the storage position of Backup Data is different from the storage position of initial data, especially by more physics
In the cluster that machine, multiple hard disks are constituted, Backup Data can be respectively present in the hard disk different with two from initial data, to prevent
The Backup Data occurred when causing entire hard disk to damage because of failure also not available situation.
Meanwhile for Reduced Design, usual Backup Data is only the mirror image of initial data, and is not had as initial data one
The practical external request of sample and the ability for carrying out related read-write operation at most only have data synchronization, increment synchronization, consistency
Differentiate etc. for realizing data backup the most basic function, when former virtual machine goes offline because of failure, the normal use of Backup Data
Method is such just as described in background technology part: finding a replacement virtual machine, Backup Data is usually copied
Mode is transferred in the virtual machine image of replacement virtual machine, then the prior fault that can be carried after the self-check program by being routinely switched on
The business of virtual machine, under such mode, with the increase of data volume in Backup Data, the point from business fault point to business recovery
Time span (RTO) greatly, and the usage experience for causing user poor.
It is different from the prior art, this step is intended to perform some processing Backup Data, makes it without that must pass through copy
It is just played a role into the virtual machine image of replacement virtual machine, i.e., by carrying out some component Configurations or adjustment, makes it can
Normally to accept request from the external access as virtual machine image, due under different actual scenes to the function of Backup Data
It can define and be not quite similar, it is possible that can not determine which specifically need handle, abstract processing can carried out according to the actual situation
(being abstracted as a kind of empty machine mirror image that can be accessed) increases and is flexibly selected in communication part and other aid in treatment modes

It in normal processing of the realization to read request, but is not the normal use method of replacement virtual machine after all, and due to many differences
In the presence of so that aforesaid way is only applicable to the fast quick-recovery of business in a short time, in order to enable complete data access request can base
It is realized in the virtual machine image of replacement virtual machine, it can also be on backstage in a manner of slowly synchronizing, by what is stored in Backup Data
Data are slowly synchronized in virtual machine image, can really realize that the virtual machine replacement of same business is made after completing data and synchronizing
Industry.
Wherein, the synchronizing speed of data can according to the actual situation lower processing read request to can backup communication data influence journey
The factors flexible setting such as degree, available bandwidth, herein and is not specifically limited.
Further, a notification signal can also be fed back after data synchronously complete, to receive the notification signal
Afterwards, disconnect and can connection between backup communication data, and withdraw it is former transfer to can backup communication data processing read request, it is unified by
The synchronous replacement virtual machine image of data is completed to be handled.
It, can be in addition, in order to further speed up the service resumption speed in the virtual machine catastrophic failure of bearer service
It, can base when the better backup available virtual machine for possessing blank virtual machine image is pre-created, and occurring needing the case where replacing
In certain selection rule choose corresponding data available virtual machine as replacement virtual machine use, in such cases, due to unlike
Copy has the virtual machine image of former Backup Data, and the process of startup self-detection can also be greatly speeded up.Wherein, selection rule include but
Be not limited to: rule, priority-based selection rule, by number selection rule etc. nearby are also not specifically limited herein, can
Flexible choice according to the actual situation.
