Abstract
The invention provides a cloud computing data storage system and method based on gridding. The system comprises a main data center and a backup data center. The main data center is connected with the backup data center through a network. The main data center is connected with a network server through the network. Data are stored in the main data center serving as a supporting point, backup data are stored through existing personal computer terminals in an encrypted mode, the main data center controls each personal computer terminal to update backup data fragments regularly, and when a disaster occurs in the data, the personal computer client-sides send stored rated data to the main data center so as to recover the lost data of the data center. Thus, the data are prevented from being concentrated at one place, the space of existing equipment can be saved, the energy consumption of the of existing equipment can be reduced, and the available safety of the data is improved.

Further, described PC client is the PC client of encrypting storage.
Further, described master data center is in order to the each PC client of timing controlled, upgrades the master data center of the data fragment of backup.
Further, when described Backup Data center, at master data center, disaster occurs, PC client wherein sends to master data center preserves specified number certificate, the data of losing in order to recover master data center.
According to another aspect of the invention, provide the date storage method of a kind of cloud computing based on gridding, comprised the steps: data storing step; Data backup step; Data recovering step.
Further, wherein said data storing step is: in the time having data to store, the webserver stores data in master data center.
Further, wherein said data backup step is: the webserver is encrypted data slicer, the real-time PC client that is distributed to registration, according to registration PC number, divide every piece of data piece equally; Master data center is numbered and collates the minutes each data block, records the information of the PC client of each data storage.
Further, wherein said data recovering step is: in the situation that master data centre data suffers damage, in master data, mind-set PC client sends and obtains data command, and PC client sends data block to master data center; In the situation that stopping heartbeat between master data center and PC, PC client initiatively sends data block to data center.
The present invention has advantages of following:
Data-storage system and the method for a kind of cloud computing according to the present invention based on gridding, take master data center as fulcrum, data are also stored in this intracardiac, Backup Data is encrypted storage by existing personal computer terminal, timing is controlled each personal computer terminal by master data center, upgrade the data fragment of backup, in the time of data generation disaster, make an arbitrary dicision to the mode of master data center transmission preservation specified number certificate and recover the data that data center loses by PC.Avoid data undue concentration in a place, can save again the solution of existing equipment space and energy consumption, improve the available fail safe of data.
Except object described above, feature and advantage, the present invention also has other object, feature and advantage.Below with reference to figure, the present invention is further detailed explanation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the data-storage system of cloud computing of the present invention based on gridding;
Fig. 2 is the schematic flow sheet of the date storage method of cloud computing based on gridding.
Embodiment
For making the object, technical solutions and advantages of the present invention more cheer and bright, below in conjunction with embodiment and with reference to accompanying drawing, the present invention is described in more detail.Should be appreciated that, these descriptions are exemplary, and do not really want to limit the scope of the invention.In addition, in the following description, omitted the description to known features and technology, to avoid unnecessarily obscuring concept of the present invention.
Fig. 1 has shown the structural representation of the data-storage system of cloud computing of the present invention based on gridding.
As shown in Figure 1, the data-storage system of cloud computing of the present invention based on gridding comprises master data center 10 and Backup Data center 11.Described master data center 10 connects Backup Data center 11 by network; Described master data center 10 is by network interconnection network server.
Backup Data center 11 is made up of multiple personal computer terminals, and example is the Backup Data center of multiple personal computer terminal compositions such as personal computer terminal 1, personal computer terminal 2, personal computer terminal 3 as shown in Figure 1, in order to encrypt the data of storage backup.When described Backup Data center 11, at master data center 10, disaster occurs, PC client wherein sends to master data center preserves specified number certificate, the data of losing in order to recover master data center 10.
Master data center 10 is huge data center, and master data center is in order to the each PC client of timing controlled, upgrades the master data center of the data fragment of backup.
Fig. 2 has shown the schematic flow sheet of the date storage method of cloud computing of the present invention based on gridding.
As shown in Figure 2, the date storage method of cloud computing of the present invention based on gridding comprises the steps:
Data storing step S1; Data backup step S2; Data recovering step S3.
Wherein said data storing step S1 is: in the time having data to store, the webserver stores data in master data center 10.
