Problems solved by technology

A single database reaches dozens of gigabytes, and the network bandwidth of shared storage is often limited to megabytes, which results in a long backup time for each database
[0004] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Abstract

The invention discloses a method and a system for database backup for solving the problems of long elapsed time and large server occupied space of the existing data backup process. The method comprises the following steps that a client cuts a to-be-backed-up data file into a plurality of files and respectively compresses the files into a plurality of compressed files; and the client obtains compression check messages of the compressed files and establishes or updates a file table according to a plurality of compression check messages, wherein the file table stores incidence relations among the compression check messages, a server path for storing the compressed files corresponding to the compression check messages, and citations corresponding to the compression check messages. According to the method and the system, the uploading file quantity is reduced through de-weight optimization, so that consumption of the server space and the uploading time can be reduced.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a database backup method and system. Background technique [0002] Reliable database services require regular full backups to remote storage. As the amount of user data increases, the time and space consumption of backups will gradually increase. The existing solution is to reduce backup time and space consumption through compression. The file system of a database such as MySQL contains multiple files. The common method is to compress all files locally into one file and upload it to remote backup, such as Alibaba Cloud. On the OSS (OperationSupportSystem, operation support system). After the file is uploaded, an access address is returned, and the client records this address, and downloads through this address when recovery is required. When it is determined that a certain backup is unnecessary (for example, beyond a certain storage time), the client calls the deletion ...
