Need help with cloud providers

Questions
1

On PG recommendations only two of them, so it is not really something I am looking for.

I need private cloud with free plan. Any free plan is ok, because I need to store tiny files (3 files, all not more than 4mb) for redundancy. I do not need paid accounts, because files are super tiny and I do not plan to upload anything beyond them.

I absolutely cannot loose this files or this will create a catastrophe for me. For privacy reasons I am not telling what these files are, but it is related to cryptography.

So my idea to store them in 3 different clouds + 3 different USB stick drives, that’s why I do not need paid accounts (I don’t need extra space, just to upload 12 MB data and forget about this)

Any good recommendations? PCloud? Filen? Mega? Proton?

There’s a few out there - including the ones mentioned. Ente Locker seems like this would do the trick?

If it’s that small, you could also use a secure e-mail?

That’s what I do now, ha-ha. But idea is to create redundancy to be sure I will never loose this files. Because if i loose them, I will be doomed and locked out from my digital life, finances and even few “smart” physical locks.

That’s interesting, I will take a look.
