Embodiment 1
[0177] image 3 A flowchart showing a method for distributed data storage according to an embodiment of the present disclosure. Such as figure 1 As shown, the method includes the following steps.
[0178] Step 302, receiving multiple usage ratios one-to-one corresponding to multiple data centers from the user end, the multiple usage ratios are set by the user.
[0179] For example, if there are data centers A, B, C, D, E, and F, the multiple usage ratios received can be: A: 20%, B: 20%, C: 20%, D: 20%, E : 20%, F: 0, or A: 20%, B: 20%, C: 20%, D: 20%, E: 20%, the latter is considered to be the usage ratio corresponding to the default data center F is 0 %. Both mean that data centers A, B, C, D, and E each store 20% of the target file, and data center F is not used to store the target file.
[0180] The user can input the multiple usage ratios at the user end, the user can adjust the default usage ratios, or choose to directly adopt the default usage ratios, etc. This disc...

[0225] Figure 4 A flowchart showing a method for distributed data storage according to an embodiment of the present disclosure. This method can be applied to the client side. Such as figure 1 As shown, the method includes the following steps:
[0226] Step 402, receiving multiple usage ratios set by the user and corresponding to multiple data centers one-to-one and sending them to the central dispatching engine;
[0227] Step 404, sending an upload request for the target file to the central scheduling engine;
[0228] Step 406, receiving the segmentation instruction and storage destination of the target file from the central scheduling engine;
[0229] Step 408: Split the target file based on the split instruction to obtain multiple data blocks;
[0230] Step 410: Based on the storage destination, store each of the data blocks in a target data center corresponding to the data block, and the target data center corresponding to each of the data blocks is used to store the ...

[0242] Figure 5 A structural block diagram of an apparatus 500 for distributed data storage according to an embodiment of the present disclosure is shown. The device can be applied to a central dispatch engine. Such as Figure 5 As mentioned above, the device 500 includes: a usage ratio acquisition module 502, configured to receive a plurality of usage ratios corresponding to a plurality of data centers from the user end, and the plurality of usage ratios are set by the user; an upload request receiving module 504 , for receiving an upload request for a target file from the client; a division and storage purpose determining module 506, for determining a division indication and a storage destination of the target file based on the multiple usage ratios, the division indication It is used to indicate how to divide the target file to obtain multiple data blocks, and the storage destination is used to indicate the target data center corresponding to each data block, and the tar...

Abstract
The invention relates to a distributed data storage method and device. The method comprises the steps of: receiving multiple use proportions in one-to-one correspondence with multiple data centres configured by a user from a user side, wherein the multiple use proportions are set by the user; receiving an uploading request for a target file from the user side; based on the multiple use proportions, determining the segmentation indication and the storage destination of the target file, so that the proportion of the total size of data blocks stored in each data centre of the multiple data centres in the size of the target file is the use proportion corresponding to the data centre; and, sending the segmentation indication and the storage destination to the user side, so that the user side is indicated to segment the target file, and store each data block obtained by segmentation in the corresponding data centre. By means of the distributed data storage method and device disclosed by the invention, users can adjust the use proportions of the various data centres by themselves according to requirements; furthermore, a central scheduling engine guides the user side to perform data processing; and thus, the user experience and the data security can be obviously improved.
Description
technical field [0001] The present disclosure relates to the field of cloud storage, and in particular to a method and device for distributed data storage. Background technique [0002] More and more users are moving their data from local to cloud. Compared with storing data locally, cloud storage is more convenient and reliable. In particular, it also has almost unlimited scalability. [0003] figure 1 A schematic diagram of an existing transfer of local data to the cloud is shown. Such as figure 1 As mentioned above, the data at the client end is connected to the remote data center through an intermediate application for data transfer, or a direct connection may be used to directly transfer the data to the remote data center. In this scheme, users are locked to a single data center, and their usage is severely limited to that data center. If users want to migrate data to another data center, it will take a lot of time, manpower and cost. [0004] figure 2 It shows a...
