If you make a backup with a tool like Borg that creates encrypted archives, then using AWS S3 glacier is the cheapest.

What’s bad about it: if you ever need those files again, it’s going to be VERY expensive to download them again, so it has to be treated as the “what if a nuke hits my city and all the local and off-site backups are vaporized” solution

Also: it’s not recommended to directly host plain files, they need to be in an archive format with big chunks, as the API calls that are used to list them during sync are counted in a very expensive way

I set garage via docker and it was not impossibly hard.

Main problem is that there isn’t an admin panel and you can’t login to the docker container via docker exec, so you have to write some python (or other language of your choice) to send requests to the API port to:

1. Set the layout of your server
2. Create an user
3. Create a bucket
4. Assign that bucket to your user

I had one of those NAS (NSA320). Even when they were new and suppoted they were using some ancient custom version of linux with ancient packages. It would be insane to expose them on the internet.
