I really thought about doing this. A Dell Optiplex has this feature in BIOS as far as I know.
So, it should be really simple from this point:
- Run systemd timer at the time of the night where the remote machine should be started
- Ping the machine on it's wireguard interface until it answers
- SSH into the machine and do some basic checks
- Run backup script to do backup via borg to remote repository
- Shutdown the remote machine
Optionally, keep a config file for the script on the local machine. For eample, I do not want to shutdown the machine after the backup one single time, to be able to do some updates of the remote machine the next morning and shutdown it by hand afterwards.
Hi,
since we get fast internet here during the next weeks, an Off-site backup gets somehow realistically.
Since my Parents-in-law also get fast internet, I discussed with them, to be able to host some kind of Off-site backup at their house.
Obviously, it should consume as little power as possible and should be as easy as possible to install.
My current plan would be to get an old Dell optiplex in SFF and put a 18TB HDD into it. The i just have to connect it to LAN and power at their site.
The machine will be always on and connected via WireGuard to my homeserver.
Any better ideas? Anything I missed?
