But not paying for it almost guarantees it.

Ultrasonic cleaner with isopropanol solution.

Jokes on you, using AI I got that time down to 4 hours trying to convince it to create working code, and 3 hours of debugging.

I would get a backup tool that offers encryption, which is most of them. Popular choices are: tarsnap, restic and Borg.

And then install graphene OS

Für die Schnellläufer Generation: früher war die SPD mal links. Dann kam Schröder und hat sie rechter gemacht. Daraufhin sind alle linken aus der SPD ausgetreten und haben ihre eigene Partei gegründet, die Wahlalternative soziale Gerechtigkeit (WASG). Weil sie irgendwie dumm waren haben sie sich mit dem Überbleibsel der DDR Regierung (PDS) zusammengeschlossen und die Linke gegründet. Damit wurden alle moderaten Linken in Deutschland unwählbar, und die SPD hatte nie wieder ne wirkliche Chance dazu, zu regieren.

Get a refurbished Lenovo thinkpad t470 or so from ebay, make sure it has full HD and comes from a commercial shop. All the Thinkpads work great with Ubuntu. They are good quality business notebooks, easy to repair with good parts availability. You can probably get one around 150 or so.

I repaired laptops for a living for a while and Thinkpads were always my favorite.

Mine doesn’t seem to exist anymore sorry.

If you assume everything is compromised, there is no safety. You have to trust something at some point.

Usually, speaking from a professional IT perspective, people trust encryption. Once you do that, it does not matter how safe or unsafe the place where you store your data is.

AES, the encryption standard used by pretty much everything, is safe. It has not been weakened in any meaningful way since its inception and is also quantum - safe.

You could use for example openssl or Veracrypt or even just 7zip to encrypt it. If you don’t trust these tools, encrypt it twice with two different ones, just put a txt file next to it with the exact steps to decrypt, because you will forget in which order you have done things.

Personally I have a homeserver that is encrypted at rest and then it uses restic to store encrypted backups in the cloud.

Ultrasonic cleaner! Really awesome for glasses, jewelry, all kinds of small stuff. I fill it with isopropanol solution and clean my phone case in it.
