Problems solved by technology

[0003] However, in the prior art, the backup server is generally only used for backup and does not work normally, which wastes the capacity of the backup server itself. On the other hand, when a failure occurs and data needs to be restored, the source database can only suspend the service and wait Data recovery, which greatly affects the serviceability of the database
[0004] For the above-mentioned shortcoming of prior art, also do not have a kind of perfect solution

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the schematic embodiments and descriptions are only used to explain the present invention, but are not intended to limit the present invention.

[0020] See attached figure 1 , which shows the applicable system structure of the database backup and recovery method of the present invention, the system includes a plurality of distributed servers for distributed storage of a database. All distributed servers are connected to each other through the network, and can transmit data to each other. At the same time, each distributed server accepts the management and scheduling of the management server, and provides database services to the outside through the management server. The network can be an internal local area network, and the advantage of using the local area network is that data can be transmitted quickly; however, considering remote d...

Abstract

The present invention relates to a database backup and recovery method, the method comprising: using multiple distributed servers to store the database and jointly provide database services; simultaneously backing up each sub-database of the database on t distributed servers, so that Said t is the backup redundancy of the pre-set database; if one of the distribution servers loses data, if E sub-libraries are stored on the distribution server, then find another E distribution servers that store the E sub-libraries respectively, restore data for it.

Description

【Technical field】 [0001] The invention belongs to the field of computer and database management, in particular to a database spare part and a restoration method. 【Background technique】 [0002] In recent years, with the advent of the era of big data, the amount of data usage has doubled, and there are increasingly higher requirements for data backup and recovery. There are two types of database backup, one is real-time backup, that is, the backup database and the source database are synchronized, and the other is backup at regular intervals. Data recovery. [0003] However, in the prior art, the backup server is generally only used for backup and does not work normally, which wastes the capacity of the backup server itself. On the other hand, when a failure occurs and data needs to be restored, the source database can only suspend the service and wait Data recovery, which greatly affects the service capability of the database. [0004] For the above-mentioned shortcoming ...
