How safe to use encrypted cloud drive?
Currently I keep sensitive information on multiple Mac OS encrypted USB drives with a very long password. They should all be identical except for the one that is kept in a bank safe deposit box, following the usual suggestion to have at least one remote copy. The drawback is that the remote drive is always somewhat out of date and requires a trip to the bank to update, so I am considering using a cloud storage such as Proton Drive.
The cloud drive is itself encrypted, with Proton not being able to access its contents, and I would only ever store an encrypted disk image on it. I read an older thread that asked about the safety of version histories on an encrypted cloud drive, which I didn't understand, but anyhow I would only ever keep one copy there.
How safe would this be? Given the nature of the contents I would have to overcome some degree of concern/paranoia. If someone stole one of my USB drives I would at least know about it rather soon. If someone downloaded my encrypted disk image I wouldn't know about it and they would have a lot of time to try to open it.
Thank you.
