Rclone can do this for you.

No reverse proxy. In LAN everything is seen and accessible.

No port is open to WAN, I connect via my router VPN from extern.

I use unpriveliged LXC für everything I have running in my proxmox.

Plex, syncthing, rclone, motioneye, pyload all in seperate Lxc on the boot drive.

All data of those is on my mirror raid, including the lxc backups. The rclone lxc backs the important data onto my cloud drive.

Proxmox

Edit: Installed as the hypervisor on bare metal and then whatever you want to try out like OMV, Plex, jellyfin, syncthing or cloud software in an LXC or VM

If you are able to translate or German is your thing check this page out https://www.elefacts.de/test-153-nas_basic_2.1__mini_itx_eigenbau_nas_mit_4x_sata_und_passiver_4_kern_cpu

At the end of the page there are 4 build links shown. Starter to expert. I went the basic model route. They also describe the different NAS OS systems, I chosed proxmox.

If your concern is booting USB for unraid the
solution is to sacrifice at least one of your drives
as a boot drive, or if you have the room get a pair
of small SAS drives and configure a raid 1 vol in
the perc controller.

AFAIK the USB is the dongle that unraid runs at all. You have to boot from it. After the boot its loaded into the RAM. But without the USB drive you cannot boot at all.

That is why I followed the proxmox route.

I got motioneye running on my server and the app on our phones

As ITX was already mentioned I just built mine using Fractal Node 304 case, in black though. You could keep the ATX power supply.

Thats basically the way I do it.

pvesh get /cluster/resources --output-format json-pretty | jq --arg k "lxc/$container_id" -r 'map(select(.id == $k))[].name, map(select(.id == $k))[].mem, map(select(.id == $k))[].maxmem, map(select(.id == $k))[].cpu')

Example using pvesh in proxmox. The data is available, just have to use it. I also prefer barebone approach.

Nice, will take a look into it

Does zabbix use a database continuously polling and storing data or is live data used for indication and/or triggers?

I ran a NSLU2 with custom firmware and a mumble server on it. We used it to talk during online gaming without the need for teamspeak etc.
Played BF3 mostly.

Those where the days

Edit: clarification

Depends, in proxmox using ZFS mirror using two drives it goes degraded when missing one.

But would use it carefully tbh as it is all that’s left over in that case. If there is no external backup.

I just built a Server almost using the same parts. Its the ASRock J5040 board, 16gb ram (yes it works) a 500gb m.2 as system using a PCI adapter , 2x4tb ironwolf as ZFS mirror pool, 350 W power supply all in the node 304 fractal case for 550 euro.

Runs proxmox as hypervisor for VM or Container. As example LXC running container for motioneye, jellyfin, pyload with openvpn and syncthing.
