Hello,

I have now 4 node cluster and every host have 3 x physical network interfaces.
Each interface is connected to its own switch.

ens1f1 = bond0
ens3f1 = bond0
vmbr0 - bond0 - 10.100.50.0/24
ens3f0 - backup lan - 10.100.60.0/24

Everthing work fine - now my question
I would like transfer Cluster - Backup and Replication communication over Backup LAN - ens3f0
I want to keep vmbr0 free for the VMs.

It that posible and what do I have to configure where

many thx....

If and only if your backup storage is also in the 10.100.60.0/24 network, the data will be transferred over the backup network

Hi,

no, my backup storage is in a third subnetz. Is available from both subnets.

My Idee:
- local backup weekly - 2 times
- nas backup weekly - 5 times over "backup lan"
- replication hourly over "backup lan" to three over nodes

I'd try to create a host route for the storage through a gateway inside of your backup lan.

The best way is to have a designated storage network or vlan on the same subnet.

Configure PVE adaptor and backup target on the same subnet and vlan.

Don’t use GW or different subnets, keep it simple for best throughout, less to go wrong and troubleshoot.

Networking best practise 101.
