Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0043] The invention designs and realizes the DMA module in the NDMP backup model and the NDMP SERVER service for receiving and sending the NDMP data flow in the backup all-in-one machine based on the NDMP protocol. The DMA module and the first NDMP server run in the backup all-in-one machine, and the second NDMP server runs in the NAS device.

[0044] 1. The DMA module, that is, the network attached data management application program, is the control center of the NDMP backup recovery program.

[0045] 2. The NDMP SERVER (NDMP server) in the backup all-in-one machine, the NDMPSERVER...

Abstract

The invention relates to an NAS data backup method and NAS data file fine-grained browse recovery method based on an NDMP protocol. According to the backup method, data in an NAS device is backed up to a backup integrated machine through the NDMP protocol. A DMA module and a first NDMP server are operated in the backup integrated machine. A second NDMP server is operated in the NAS device. The backup method comprises the steps of A1), establishing control connection between the DMA module and the first NDMP server, and between the DMA module and the second NDMP server, and data connection between the first NDMP server and the second NDMP server; A2), sending a backup instruction to the second NDMP server and sending a recovery instruction to the first NDMP server by the DMA module; and A3), receiving NDMP data stream by the first NDMP server, wherein the NDMP data stream is sent by the second NDMP server, writing a file object obtained after the NDMP data stream is analyzed into an object file system, thereby finishing backup. Compared with the prior art, the methods have the advantage of facilitating uniform storage and management of the data.

Description

technical field [0001] The invention belongs to the field of computer storage technology and data management technology, and in particular relates to a method for NAS data backup and file fine-grained browsing recovery based on the NDMP protocol. Background technique [0002] Data backup has always been an important research field of computer storage technology and data management technology. It is to prevent data loss caused by system operation errors or system failures, and copy all or part of the data set from the hard disk or array of the application host to other storage media. [0003] Traditional data backup mainly uses built-in or external tape drives for cold backup. But this method can only prevent man-made failures such as operating errors, and its recovery time is also very long. With the continuous development of technology and the massive increase of data, network backup realized by professional data storage management software combined with corresponding har...
