Management plane of the network planes for the eBackup
The management plane is divided into two sub-planes: backup management plane and production management plane. The backup management plane serves as the communication plane for eBackup to provide external services. You can use the IP address of this plane to log in to the eBackup backup management system through a maintenance terminal or a third-party system to configure and manage backup and recovery services. The production management plane serves as the communication plane between the backup server/backup proxy and the management plane at the production end.

eBackup storage plane
The storage plane is divided into two sub-planes: production storage plane and backup storage plane. The production storage plane serves as the communication plane between the backup server/backup proxy and the storage plane at the production end. The backup storage plane serves as the communication plane between the backup server/backup proxy and the backup storage.

Failure to access the management plane of the eBackup
Security of the eBackup has been hardened. By default, only those external systems which are in the same network segments as the eBackup network planes can access eBackup servers. Therefore, you need to configure other network segments or IP addresses that need to be connected to the management plane. Configure routes and firewalls in sequence.

Failure to access the eBackup storage plane
Security of the eBackup has been hardened. By default, only those external systems which are in the same network segments as the eBackup network planes can access eBackup servers. Therefore, you need to configure other network segments or IP addresses that need to be connected to the storage plane (including the production storage plane and the backup storage plane). Configure routes and firewalls in sequence.

Number of network planes needed to be planned during eBackup installation
For the eBackup software to work properly and safely, the following network planes must be configured: management plane, internal communication plane, and storage plane. To ensure network security, the three network planes (management plane, internal communication plane, and storage plane) must reside in three different network segments for isolation from each other.
