Add to that: backup, and allow restore of, network interface configurations.
My HA implementation has four network interfaces, all configured statically. After a recent failure&subsequent restoration from full backup, all four interfaces had to be reconfigured - some things were broken until that got done.
My implementation lives on Linux in a VirtualBox vm with four bridged network interfaces defined. Does that perhaps introduce a complication that prevents normal backup&restore of the network configs?
That would be difficult to implement when using a backup to migrate to different hardware. Though I guess not impossible if it could be deselected like other sections in a partial backup.
The restoration process to which I referred was to the same server/hardware.
I’ve no experience with anything except VirtualBox, but the vm would abstract from the OS/hardware level, so possibly could be restored even to a different host, within reason?
