(Optional) Configuring HA

You can configure high availability (HA) for backup servers to enhance the reliability of backup servers.

Prerequisites

You have determined the backup servers and backup proxies corresponding to the active and standby HA nodes.

Context

HA refers to that active and standby modules work in hot or cold backup mode to implement specific functions. When the active module is faulty, the standby module automatically takes over the role of the active module to implement system functions, improving system reliability.

To enable eBackup to support the HA function, plan at least two eBackup servers (with one initialized as the backup server, and the others as backup proxies). After eBackup is installed and configured, the HA function is disabled by default. You need to configure HA parameters to configure eBackup as an HA system. After the configuration, the backup server and one backup proxy work in active/standby mode. If the backup server fails, the backup proxy takes over the role of the backup server to ensure normal system operation.

Procedure

  1. On the navigation bar, choose > Server.
  2. (Optional) In the upper right corner, set the search criteria and click to search for the desired server.
  3. Click the drop-down arrow of HA Management and choose Add HA member from the shortcut menu.
  4. Select a backup proxy whose Accessibility Status is Accessible, and Register Status is Registered as the standby node in the HA system as prompted. Then set the backup server as the active node.
  5. Configure Floating IP address and Quorum gateway(s).

    Quorum gateways must be able to communicate with management planes of active and standby nodes. The IP addresses of the quorum gateways must be unique and must not start with 127.
