Embodiment 1

[0039] like figure 1 As shown, this embodiment provides a LAN-free backup system, including production servers 2 and 3 deploying backup client modules, backup server 1 deploying both a media service module and a main control service module, an FC switch 5, and an Ethernet switch 4. Backup server 1 is connected to production servers 2 and 3 through FC switch 5 and Ethernet switch 4 respectively. Backup server 1, production servers 2 and 3 are all equipped with HBA cards supporting FC protocol.

[0040] The main work of the main control service module includes the following parts:

[0041] 1. Manage and configure HBA cards, and monitor the operation and transmission status of HBA cards at the same time. The operation and transmission status includes the data volume and error information transmitted on the HBA card link.

[0042] 2. Initiate and end the backup (restore) task through LAN, and manage the data source information of the corresponding application on the production se...

Embodiment 2

[0060] In the LAN-free backup system provided in this embodiment, the main control service module is installed in another backup server independently of the media service module. The rest are the same as in Example 1.

Abstract

The invention relates to an LAN-free backup system. The system comprises a main control service module, a medium service module and a backup client module. The backup client module is mounted in a production server; the medium service module is independent of the production server and is mounted in a backup server. The backup client module, after receiving a backup task command, encapsulates required data into a specified data block format and transmits the data to the medium service module via an SAN; after receiving a recovery task command, the backup client module receives a data block from the medium service module and writes the block into a client storage. In a backup process, the medium service module receives the data block from the backup client module, and writes the data block into a backup storage; in a recovery process, the medium service module takes out a corresponding data object from the backup storage according to a recovery time point, and encapsulates the data object into a data block, so as to implement recovery. Compared with the prior art, the system provided by the invention has the advantages of: solving the problem that a backup window is too big, implementing flexible configuration and dynamic adjustment of the medium module, and being easy for integration.

Description

technical field [0001] The invention relates to the technical field of computer data backup, in particular to a LAN-free backup system. Background technique [0002] In the field of information technology and data management, backup technology is to copy and save the data of the file system, database or other production server applications to the storage managed by specific media services. The data recovery in the storage where the media service is located can restore the normal operation of the original production server. [0003] The traditional backup technology is backup through LAN, that is, the backup data flows to the storage managed by the media service through the Ethernet. The efficiency of this backup method will be affected by the inherently high network delay and computing resources of Ethernet, and at the same time, the backup data will occupy the network bandwidth of the production server. [0004] With the wide popularization of storage area network (SAN) d...
