Download or backup to network drive?

I’m running HA on proxmox as an lxc container. I have HACS and Integrations but no addons. I haven’t had any need for it yet as I have all my servcies like mqtt/nginx on proxmox containers.

Now I am struggling to find a way of moving the core backups to another drive on my network.
I can use autobackup to create the backups on a schedule but have to download them manually and move them.
Seems the download path option is only local to homeassistant and can’t add any shared network paths.

Is there any option to automate download to a network share in my case? (No addons as it is not supervised)

I do back up the containers but would like to grab the core config files as another backup

Only other option I see is using synbackfree from ./backups
