And how do you communicate with the Pi0?
Comment on Options for remote Wake-on-lan. Or I guess wake on WAN.

You could use a very low power computer that’s always on like a Raspberry PI Zero W to send the WoL packet to the backup computer. It only uses about 1 watt. Some routers have the ability to send a WoL packet as well.

Wireguard between you and remote device like a pi. Set pi to portfowarding and masquerading on. It will then let you be on say a 10.x.x x network remotely but will send info on the remote LAN like it came from that pi local IP

Use SSH. Ether open a port in the firewall or connect it to a VPN. If the backups are done on a schedule, you could also setup a cron job on the Pi to send the WoL packet a few minutes ahead of time.

Use a VPN; don’t open up SSH to the internet.

Or just be cautious, thoughtful and sensible if you do. Only a Sith deals in absolutes.

Ssh over Internet is fine as long as it’s properly setup (no password auth, root not allowed, etc.).

You can even use an ESP32 or similar since it just has to perform 1 tiny function.
Getting an WT32-ETH01 knockoff dev board for 15€ or PoE for 25€ and uses <300mW with the wireless modem off. You could even just use a WiFi module for 8€ if you don’t want something wired.

There is already an wakeonlan library to generate a packet very easily.
You can even do it in pseudocode with ESPHome if you have HomeAssistant

this sounds like it requires another computer already turned on

Depends on your hardware. My routers can serve as a Wireguard serveur, so no need for a computer for that part
