Data real-time backup method, implementation system thereof and backup device

Abstract

The invention provides a data real-time backup method, an implementation system thereof and a backup device. The implementation system comprises a storage device and the backup device, wherein the backup device extracts data from the storage device directly in real time, and the data is saved into the backup device. The backup device comprises a backup space management unit, a storage device management unit and a data backup management unit. According to the data real-time backup method, the implementation system thereof and the backup device, the backup device with backup management and SAN storage functions is connected with the storage device, variation data is confirmed on the storage device, the variation data is read and saved into backup space of the backup device, then the variation data and previous backup data are merged into a piece of new complete full-backup data, and therefore data backup can be performed in real time and has a small influence on business system performance of a business server. The backup method is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of backup data, in particular to a method for backing up data in real time, a system thereof and a backup device. Background technique [0002] Such as figure 1 As shown, the existing mainstream backup technology is that the backup server 1 reads the business data in the storage device 4 through the business server 2 and the optical fiber connection device 3, and saves the read data in the backup server 1 to realize data backup. safety protection. [0003] However, in this data backup method, the data reading method of the backup server 1 is related to the operating system of the business server 2 and the software platform used by the business system. For example, if the backup server 1 wants to back up the oracle database, it must The backup interface is used to read data. If the backup server 1 wants to back up the MS-SQL database, it needs to read the business data through the backup interface of the MS...
