Problems solved by technology
However, this patent has this problem when it is used: when uploading, the request needs to know the overall summary of the file and the overall size of the file, so that it is necessary to traverse the file and calculate the summary of the file before uploading, thus consuming certain resources; when there are many requests for uploading files, uploading When the file is large, the resource consumption may be relatively large
However, the user cannot customize the data size of a download, and the success rate of a download cannot be guaranteed. If the download is interrupted, the next breakpoint resume download is required, which increases the uncertainty of calculating the number of guaranteed message summary information. When downloading a file request When there are many, and the download file is large, the resource consumption may be relatively large

Embodiment Construction
[0038] specific implementation plan
[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0040] like figure 1 As shown in the figure, it is a data block storage structure diagram of the embodiment of the present invention. When a piece of data (the data ID in this embodiment is 1) is saved in the storage server, there can be multiple versions of data, but there can only be one complete version of data—that is, data with complete data (in this embodiment, the order of adding time is respectively It is complete version data 1 and incomplete version data 2, 3, 4); each version data (data volume exceeds the set value) will be split into multiple data blocks, and the specific data block method is:
[0041] Step 1. Split a piece of data into multiple data blocks according to the specified data block s...

The invention relates to a breakpoint resuming method based on segmentation and meta-information. The method comprises a data storage method, a breakpoint uploading method and a breakpoint downloading method. In the data storage method, when data is stored in a storage server, multiple versions of the data exist while only one of the multiple versions is a complete version, and the data of each version is split into a plurality of data blocks, wherein one data is split into the plurality of data blocks according to a specified size of the data blocks, and the size of the last data block is the actual size of the data block; corresponding data block meta-information is generated for each data block. The meta-information comprises data block adding time, a data block number, data block size, a digital signature and a KEY. In the breakpoint uploading method, a user calls an uploading interface of the client to input an uploading parameter; 2) the client initiates a request for reading the meta-information of the last data block of data, with the ID, of this version; 3) the server obtains the meta-information of the last data block of data, with the ID, of this version after receiving the request of the client.
Description
technical field [0001] The invention belongs to the communication field of a file storage system, and in particular relates to a method for resuming transmission based on block and meta information. Background technique [0002] With the development of modern IT systems, the scale of data is getting larger and larger, so many companies have adopted the form of file storage to store unstructured data, such as pictures, videos, documents, etc. In the daily upload and download operations of data files, if the amount of data is large, and the data upload and download fail due to network instability and other reasons, all the data saved in the form of file storage needs to be uploaded or downloaded again, which is a waste of time , and waste traffic, and may even fail to upload or download multiple times, resulting in poor user experience. [0003] On these issues, the patent application "A method and device for resuming transmission of cloud storage files" (application number: ...
