As others have said, torrents won’t work as a backup. This is because when you create a torrent, it isnt uploaded to a server somewhere, other users download directly from you. So if you have it as a torrent, until someone else downloads it, you only have 1 copy.
If you want to use it to upload stuff from your laptop to another PC, then this would actually work, and the only thing needed to avoid it being public is to not share the torrent file itself publically. But there are better tools for this, such as SyncThing. Torrents will work once, but any changes to the files will break the torrent.
