Fig. 1 is a schematic flow chart of a remote data synchronization method according to an embodiment of the present invention. In this embodiment, the remote data synchronization method includes:
and S1, extracting preset type source data from the first data center to obtain a target file.
As is known, data centers are used for backing up data, so that disaster tolerance of the data is improved, when an accident occurs in one data center, another data center can still store data of an enterprise, and data transmission under the condition only needs to ensure integrity of the data. However, in another situation, such as when the data application of data center a needs to be put into use immediately after some data collection ground, but the data is actually collected and grounded in data center B, a low-delay data synchronization service between data centers a and B is needed to transfer the data of the data centers for the first time.
In detail, in the embodiment of the present invention, the extracting preset type of source data from a first data center to obtain a target file includes:
monitoring the data updating condition in the first data center in real time by using a preset monitoring service;
and if the first data center generates a new data file, automatically extracting the new data file to obtain the target file.
In the embodiment of the present invention, the monitoring service is an executable program, and is configured to monitor whether a new file exists in a file directory in a database of the first data center.
Specifically, in the embodiment of the present invention, when a folder is newly constructed in the file directory, the monitoring service is executed, and a file in the newly-added folder is extracted as the target file.
And S2, extracting the file content and the file structure in the target file by using the pre-constructed traversal service.

If a text content is "I am a Chinese font style, I am from Chinese". The compressed encoding is: i am a 0001, I am from 02. The length after compression coding is reduced significantly.
Further, the repeated characters in the primary compressed file can be labeled by using the huffman coding algorithm to obtain the compressed file, for example, the frequency of the character string "aaaaabbbccddd" is used instead of the frequency, and the frequency of the character 'a', b ', c', d 'is respectively' 6 ', 4', 2 ', 3'.
In the embodiment of the invention, by utilizing the Huffman coding algorithm, firstly, the node weights are 6, 4, 2 and 3, and the minimum 2 and 3 are selected to form a combined node with a root node of 5. The current node weights are 6, 4 and 5, and the minimum 4 and 5 are selected to form a combined node with a root node of 9. The current node weights are 6 and 9, and the minimum 6 and 9 are selected to form a combined node with a root node of 15. The current node weight is 15, only one node is needed, and the Huffman tree is established.

and at the second data center, decompressing the compressed file into the text structure by using the text encryption label to obtain the restored source data.
In the embodiment of the present invention, a program for periodically generating a new access token exists between the second data center and the first data center, so as to ensure that data between the first data center and the second data center is not easily intercepted, and also ensure that information of other devices cannot interfere with the first data center and the second data center.
According to the embodiment of the invention, by extracting the key fields in the access token, such as the effective time and the identity information, when the identity information is matched with the first data center and the effective time is not expired, the access token is judged to be effective, otherwise, the access token is invalid.
Further, in the embodiment of the present invention, in the second data center, a new hive table is automatically constructed according to the text structure transmitted by the second data center, and the same file name as the compressed file is assigned. And the second data center analyzes the file encryption label through a preset decompression tool, judges whether the file encryption label corresponds to the compressed file or not, and does not decompress the compressed file when the file encryption label does not correspond to the compressed file. And when the source file and the source file correspond to each other, decompressing the compressed file into the new hive table to obtain source data corresponding to the compressed file, wherein the content and the structure of the source file are changed.
Further, in this embodiment of the present invention, after the decompressing, by using the text encryption tag, the compressed file into the text structure to obtain the source data corresponding to the compressed file, the method further includes:
encoding the source data by using a pre-constructed encoder to obtain encoded data;
and segmenting the coded data according to a preset rule to obtain each data block, and performing distributed storage on each data block.
In order to ensure that data can be safely stored and is not easy to lose along with time, the embodiment of the invention generally adopts a distributed storage mode to store the source data.
In the embodiment of the invention, source data is converted into coded data by using an encoder, the coded data is encrypted by using an erasure code to obtain an encrypted coded block, the encrypted coded block is cut into blocks according to a specific cutting mode of the erasure code to obtain a plurality of data blocks, and finally the data blocks are stored in each memory of the second data center in a distributed manner, wherein the erasure code is a data protection method and can divide data into segments, expand and encode redundant data blocks and store the redundant data blocks at different positions, such as a disk, a storage node or other network positions.
