Transferring from remote to remote?

What flags are you guys using to transfer from remote to remote using rclone? I’m transferring about 15 TB, about a million files total of smaller (KB-MB) and large (1-20 GB+). Trying to move completely from one cloud provider to another. Should I be using sync or copy?

I’m using copy after a bad experience with sync.

I never use sync

I just use rclone copy -v --transfers 10 --checkers 10 remote1: remote2:

Play around with the transfers and checkers number, as sometimes it goes faster with less…

is it normal for deleted files to still show up as data used in google drive? I’ve deleted them and also cleared trash but they are still showing up in recents

It takes time…wait…
