Hello everyone, I am a long time lurker of this channel, and I finally decided to write my first post.

Two years ago I used my old desktop PC to run a home server using TrueNAS Scale. It is still running at the time of writing this.

It works so well in fact that I have grown more dependent on it over time. First it was just Jellyfin, then came all the Arr apps, Adguard, Syncthing, Immich, Forgejo, Wireguard...

What was supposed to be the "PC for backups" has turned into the angular stone of all my computers and devices.

The reason why I am posting today is because I am afraid of the day my server dies or I have to move out of my place (which might happen soon)

Does anyone know if it is possible to rent a cloud server where I could install TrueNAS and then have that be a "replica" of my local one to use in case of an emergency? Is this a bad idea? What is the ideam solution for this issue?

Use something like Backblaze or Hetzner storage boxes for off-site backups. There are a number of tools for making this painless, so pick your favorite. If you have the means, I recommend doing a disaster recovery scenario every so often (i.e. disconnect existing drives, reinstall the OS, and load everything from remote backup).

Generally speaking, follow the 3-2-1 rule:

3 copies of everything on
2 different types of media with
1 copy off site (at least)

For your situation, this could be:

3 copies - your computer (NVMe?), TrueNas (HDD?), off-site backup; ideally have a third local device (second computer?)
2 media - NVMe and HDD
1 copy off site - Backblaze, Hetzner, etc

You could rent a cloud server, but it'll be a lot more expensive vs just renting storage.

Every night my NAS wakes up, fetches the data from my unraid server, backs it up and also sends an encrypted backup to a hetzner storage box on a server in a different country. Haven't had to use it yet, but in theory works fine. Should do some more regular testing though...
