Abstract

The embodiment of the invention discloses a backup method, a master server, backup servers and a backup system. The method includes the following steps: receiving load sampling information sent by thebackup server in the backup system that comprises at least two backup servers; according to the load sampling information, determining the load information of the backup server and according to the load information, determining the backup server with lightest load in the backup system; and sending backup operation to the backup server with lightest load so that the backup server with lightest load stores the backup data stream corresponding to the backup operation in a storage array. In LAN-Free framework, the embodiment of the invention improves the utilization rate of SAN bandwidth resources and the whole backup performance of the backup system, shortens a backup window, makes up the defect that the treatment of backup operation fails when the backup server goes wrong and improves the robustness of the backup system.

Description

technical field [0001] The embodiments of the present invention relate to the field of data backup, in particular to a backup method, a master server, a backup server and a backup system. Background technique [0002] Various backup technologies and backup methods derived from various backup technologies are constantly developing as people's awareness of the importance of data protection deepens. Due to the surge in the amount of corporate data and personal data, the burden on the backup system is increasing, and the backup window is too large. Therefore, backup performance has become one of the important indicators that must be paid attention to when building a backup system today. Wherein, the backup window refers to the time interval for performing data backup without seriously affecting the application program using the data that needs to be backed up. [0003] In terms of backup media selection, the traditional backup method that simply uses tapes as media is graduall...
