I would like to use a cloud backup service on my home server. I am a complete beginner. I purchased a subscription for Proton Drive, but it looks like that just won’t work. Is there a secure cloud backup that works well on Linux? Bonus points if there’s a way to use proton drive. Extra bonus points, if I can set it up for automatic backups through a GUI.
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
