Embodiment Construction

[0029] Embodiments of the present invention are described below with reference to the drawings, in which like parts are denoted by like reference numerals.

[0030] Such as figure 1 As shown, the database backup and recovery system based on blockchain technology of the present invention mainly consists of three modules:

[0031] Database adapter: bridge between one or more databases and the conversion center;

[0032] Blockchain adapter: bridge between blockchain nodes and conversion centers;

[0033] Conversion center: connect the client, connect to one or more databases through the database adapter, and connect to one or more blockchain nodes through the blockchain adapter.

[0034] In the system, the database adapter can adapt to different types of databases, and can identify and process operators of different types of databases. Database adapters can convert between raw SQL statements and general statements for different types of databases.

[0035] The database adapte...

Abstract

The invention provides a database backup and recovery system based on a block chain technology. The database backup and recovery system comprises a switching center, wherein the switching center is connected with a client side, is connected with one or a plurality of databases and is connected with one or a plurality of block chain nodes through a block chain adapter, and the switching center manages mapping relationships between the plurality of databases and the plurality of block chain nodes for data backup and recovery. The invention also provides a database backup method based on the block chain technology, and a database recovery method based on the block chain technology. The block chain technology is used, the characteristics that the block chain technology can not be tampered and can be permanently stored are utilized, meanwhile, data is distributed in the block chain nodes, overall failure caused by the faults of a center point can be avoided, so that safe and reliable database backup is realized, most of organizations can properly control cost and effectively deploy a backup scheme in existing environment to enable the requirements of most of organizations to be met, and the methods and the system can be generally implemented and have a very wide application scene.

Description

technical field [0001] The present invention relates to the technical field of data backup and recovery, and more specifically, to a database backup and recovery method and system based on blockchain technology. Background technique [0002] In the traditional database backup process, redundant hardware, software, and related manpower are generally required. For some organizations that have backup needs but cannot afford the high cost, they can only wait and see; and for some existing backup solutions, the utilization rate is often not high, and there is a great waste of resources. Therefore, there is a need for a reliable, secure, versatile, and inexpensive backup method that properly meets the needs of various organizations. [0003] Transaction log (Transaction Log) backup: only back up the content of the transaction record file, because the transaction log file will only record the changes we made to the database after the previous database backup or transaction log rec...
