Is Restic with an Rclone Encrypted remote a good idea?

[Eli6]

Same question:

Is rclone's crypt remote as a restic backend a bad practic?

I want to use rclone backend to move around restic repositories. The rclone crypt backend is interesting because it adds another layer of encryption in addition to moving operations. This shall protect against restic zero days, bugs or flaws not caught by the developers. The replacement of GCM with Poly135 authentication in restic is certainly nonstandard. Is there a reason for not using the standard encrypted authentication AES-GCM or ChaCha20-Poly135? Restic apparently is not audited yet (th…

Restic + rclone encryptions

Hi, Imagine the following use case: backup to a secure trusted server then push the repos to an untrusted cloud using rclone. Since restic (which has been designed to store your data on untrusted location) is using scrypt which can be very extensive to crack, especially with a long repo password (see https://www.tarsnap.com/scrypt/scrypt.pdf). Would it make sense to also encrypt the repos with rclone while pushing them to the cloud or would it be overkill or would it introduce a flaw in some w…
