Some have speculated that with the introduction of the PSI/CSAM system Apple will enable E2EE backups. Given the lack of an explicit statement on Apple's part and their history regarding E2EE backups (this article, and other statements). It seems really unlikely to me that Apple will enable E2EE backups. Under E2EE, assuming the device key is randomly generated, if you have one device (as many users do) and you lose…
An obvious solution would be to allow third-party storage services where you can dump your device data pre-encrypted and restore from those services. Only you would have the key. It isn't hard to implement. The hard part would be getting the US security apparatus to allow it. ALL major storage providers DON'T support end-to-end encryption for this reason. Not Google. Not Microsoft. Not Apple. Not Dropbox. Isn't this…
I don't think so. The reason is there's no money to be earned with being simply a storage provider. Additional processing, indexing, workflow tools etc. is what people pay for. That's not possible with E2E encryption.
