Example Embodiment

[0054] See Figure 8 , The process of method embodiment two includes:

[0055] S801: Set up at least two mirroring channels between the two motherboards, set one of the mirroring channels as the active channel, and the others as the backup channels;

[0056] S802: When the main channel is normally connected, the backup data is transmitted through the main channel;

[0057] S803: When the main channel fails, start the backup channel to transmit the backup data.

[0058] To image 3 As an example, the system defaults to mirror channel 1 as the active channel. When the mirror channel 1 is connected normally, the backup data is transmitted through the active mirror channel 1. When the active channel fails, a normal backup channel is started, for example , Start mirroring channel 2 to transfer the backup data.

[0059] In the second embodiment, since only one mirroring channel is used for traffic transmission, the implementation and control are relatively simple, and only the currently...

Abstract

The invention discloses a storage system data backup method, including the following steps: setting at least two mirror-image channels between the first main board and second main board of the storage system; proportionally transmitting the backup data in the at least two mirror-image channels when the two mirror-image channels are all in normalized communication; and using the other normalized channels to transmit the backup data if some mirror-image channels are in fault. The invention can balance the transmission flow quantity by normal mirror-image channels, which can maximize the bandwidth utilization of the mirror-image channels. And corresponding to the above-mentioned method, the invention also provides a data backup storage device.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data backup method and device for a storage system. Background technique [0002] In a dedicated storage system, it is divided by function, including the control head and disk array, and the two can be combined into one in physical form. Generally, the reliability of the control head of the low-end storage system is relatively low, including only one control board (only one controller), while the middle-end or high-end storage system requires high reliability, not only the input power of the system, the system The power supply module, battery, and access to the switch and disk array must at least meet the "1+1" backup requirements. Moreover, the mid-range system contains two controllers, and the high-end system control head will contain more than two controllers. server, the data in it also needs to be backed up. [0003] see figure 1 , which is a schematic diagram of...
