That’s odd behavior, haven’t seen that before myself. I had to try a few times, the command that finally got it to sync for me was as follows:

rclone sync ./borg crypt:/borg/ --verbose --retries=10 --low-level-retries=20 --drive-chunk-size=32M --protondrive-2fa 123456

then I followed up with a --protondrive-replace-existing-draft=true to fix the remaining errors.

YMMV. Hope you’re able to get it working!

FYI: RClone added proton drive support. just synced a 220gb borg archive over last week.

Sweet!

I havent been following the news for a while, has proton drive exposed an API or an SDK to allow for rclone support?

Please say yes, I’ve been wanting this for years.

Edit: omg no way! https://rclone.org/protondrive/

Unsure why this is where the line is drawn, but okay.
