welcome to the forum,
fwiw, i would not trust rclone+proton for important data and certainly not for backups.
- there are more bugs and issues with proton, then most any other backend.
- rclone relies on a third-party library, which when i last check, is not being updated.
- proton considers rclone usage an abuse of their system.
We have noticed that your login attempt to your account was blocked, due to your "Rclone" usage.
We would advise you to stop using "Rclone" for cloud management, to avoid further interruptions.

the fastest, simplest and more reliable method is rclone sync|copy|move
