Not sure what the point is with this new service, except /e/ making another huge pile of cash. We have already tons of providers with all kinds of plans and possibilities. And, most importantly, as long as you are keeping your data on someone else’s computer, it’s almost as unsafe as keeping it in Google Drive. The only exception is, when the provider can prove to you, that all that stuff is E2E encrypted, which means everything is encrypted and decrypted locally on your computer and the provider never sees any exploitable data.
This naturally implies, that if you lose your private keys, you will lose all your data.
Alternatives, I frequently recommend, because I personally love to use them:
Keeps data safe on any cloud, by encrypting everything locally, adding an additional layer of security to your cloud storage.
The provider will never see your data unencrypted.
My favourite cloud storage provider, because of the product’s features, the open source clients that work on Linux, etc. and because of a big focus on privacy, like e.g. E2E encryption and more.
However, any cloud storage providing E2E encryption should be enough, if you want that extra security. Make sure the official client provided by the provider is open source or, if it is not, make sure it is compatible with RClone.
