Backup and recovery method capable of supporting online concurrency of multi-level data and database

Abstract

The invention discloses a backup and recovery method capable of supporting online concurrency of multi-level data and a database. Backup data recovery is performed by executing the following steps of starting up all backup proxy servers and backup data servers, and registering to a master control server; selecting a backup task category by a supervisor console, wherein the backup task category comprises a catalog backup or a user full backup; issuing a backup data task request message or a database backup task request message to the backup data servers and the backup proxy servers by the master control server; start uploading or downloading a data command after the backup data task request message or the database backup task request message is received by the backup data servers, establishing a backup file storage catalog according to a task number, then, enabling a file transmission service, and receiving file upload or download links of the backup proxy servers; sending a task completion message to the master control server after the transmission of received uploaded or downloaded file data is ended. The backup and recovery method disclosed by the invention meets the massive data storage and backup requirement, and supports online data backup and recovery.

Description

technical field [0001] The invention belongs to the field of computer data storage, in particular to an online concurrent backup and recovery method supporting multi-level data and databases. Background technique [0002] At present, people are more and more dependent on data, the carrier of information, and the research on key technologies for backing up data is getting deeper and deeper. At the same time, with the rise of computer network data storage technologies such as cloud storage, reliable backup data methods are particularly important. [0003] Commonly used backup and recovery mechanisms have the following problems: [0004] (1) The hot backup method cannot solve the problem of data loss caused by accidental deletion by the operator, because the hot backup system will regularly synchronize the data of the two machines to ensure data consistency. Once data is deleted by mistake, it cannot be recovered. [0005] (2) The reliability of the backup medium tape is poo...

AI Technical Summary

Problems solved by technology

[0005] (2) The reliability of the backup media tape is poor, it is difficult to save, and it is easy to fail

The access speed of the tape drive used is too slow, and it takes too long to back up data once

[0006] (3) The data storage and backup method is close to manual, which is difficult to meet the needs of efficient online backup of data

[0007] (4) The backup and recovery of the host operating system and application system are done manually. The serious consequence of this situation is that once the operating system or application system fails to run normally due to a hard disk failure, it will take a long time to restore

Functions such as dual-machine hot backup, disk array, disk mirroring, and automatic replication of database software cannot be called a complete data storage backup system. They only solve the problem of system availability, and the reliability of the computer system requires complete backup data. management system to solve
