Usage Guidelines

Configuration Impact

Each business group determines its backup relationship based on priorities.

You should appropriately set the number of backup nodes. If a large value is set, a large amount of bandwidth will be occupied for backup, compromising the performance of the cluster system.

Example

# Set the number of backup nodes to 3.

<sysname> system-view
[sysname] cluster backup node-num 3
