To bring the conversation back to rclone, do I need to tell rclone to use multipart-upload somehow?
I have set everything else up, got a bucket, configured it all in rclone, solved my policy topic at least in the basics, tar.gz archived my files and encrypted them with gpg so really all I need is to copy them to s3 but need to use multipart upload since single archive files are big.
Ok, further research, answered my own question:

Thank you very much again for all your help @asdffdsa !!!
