Method and device for hot loading disk filter driver

Abstract

The application aims to provide a method and device for hot loading a disk filter drive. Specifically, the method comprises: determining a corresponding disk drive of a to-be-protected disk; obtaining a first entry address of a write request processing module in the disk drive; replacing the write request processing module in the first entry address with a write request forwarding processing module; and forwarding a received write request on the disk to the corresponding disk filter drive through the write request forwarding processing module to perform processing. Compared with the prior art, the method has the characteristics that the address of the write request processing module between the to-be-protected disk and the corresponding disk drive is determined, the write request processing module in the address is replaced with the write request forwarding processing module, and the received write request on the disk is forwarded to the corresponding disk filter drive through the write request forwarding processing module to perform processing, so that the purpose of hot loading the disk drive is achieved, the operational stability of the protected disk is kept, and the manual operation and maintenance costs are reduced.

Description

Technical field [0001] This application relates to the computer field, and in particular to a technology for hot-loading a disk filter drive. Background technique [0002] With the advent of the era of big data, cloud computing, data mining, Internet applications and other technologies have developed rapidly, and the stability and security of data storage disks have become increasingly important. Therefore, in the prior art, a disk filter driver is added to the protected disk to send the intercepted data to the backup management system, thereby achieving data protection on the disk. [0003] However, in the prior art, when adding a disk filter driver, it is often necessary to replace the original mounting device with a disk filter driver device, so that the system needs to be restarted when installing and uninstalling the disk filter driver, which interrupts system operation and reduces operational stability. Moreover, the corresponding relationship between the protected disk and ...

Problems solved by technology

[0003] However, in the prior art, when adding a disk filter driver, it is often necessary to replace the original mounting device with a disk filter driver device, so that the system needs to be restarted when the disk filter driver is installed and uninstalled, so that the system is interrupted and the operation stability is reduced. And because of the change of the mounted device, the corresponding relationship between the protected disk and the mounted directory also needs to be modified, which increases the management complexity of the operation and maintenance personnel and increases the labor cost
