Thanks Nick, but now I'm struggling to setup the remotes correctly
My an unencrypted remote with 100tb (mymedia:) is a google drive teamdrive and I want the unencrypted remote (encrypted:) to be located in a different teamdrive,
the encryptred file gets copied to the unencrypted teamdrive. I guess something is wrong on the encrypted remote of my rclone.conf but can't figure out what.
