Thanks Carl and Carlos. I've got home work to do now :-)
Interesting point. A zero-knowledge backup provider should only be allowed to call itself zero-knowledge if its access platform (client) is made or verified (ideally made really) by a third party. Otherwise you have a conflict of interests. You cannot depend on some other party always being able to make the moral high choice. What if law enforcement forces them to change their client without notifying you? If you have an independent client that is really fully independent and cannot be retracted by any party, meaning it would have to be open source, only then can you say you have a zero-knowledge encryption storage platform.
In Linux we solve it by encrypting thing ourselves I guess :-/.
Just to give feedback about my "home work": - all cloud services that are easy to find (let's say top 25) use their proprietary clients, which means you give full root access to some company. It's like giving the key to your house and car to somebody you don't know. In fact, it is giving complete access to bank accounts, credit cards, tax declarations, book keeping, clients list and private stuff. Even with "client side encryption" the proprietary, closed source program still has root access plus internet connection and this is such a high risk that I really wonder why somebody uses such programs.... - The only reasonable solution (to my eyes) is to rent pure disk space somewhere (I found for example https://www.hetzner.de/gb/hosting/storagebox/bx40 ) and to upload self-encrypted files. I guess a program like https://cryptomator.org/ can make that task easier. I wasn't going deeper into the matter because in the end I decided not to use any online storage. Not because of lack of offers, but because my files are too large. I was dreaming of an online-solution to backup photo shootings, which are between 5 and 40 GB. If my math are right, with my current internet connection the upload of 1 GB would take about 215 minutes (speed test says I have 0.62mbps, telefonica, Spain) and en route any upload would take way longer than the battery of my laptop works. I admit, I took the large way to come to this conclusion :-) Thanks again for the input, which gave me a good starting point.
