Cloud sync - rclone aux parameters?

Jul 28, 2017
I want to setup cloud sync on my freenas to a Backblaze B2. I've done some tests and everything works fine from the sync perspective however things fall apart with regard to my internet connection. Either my router or my modem simply locks down if the uplink is saturated for long enough time (and it's not that long - about 30min suffice). I was inspecting how cloud sync is done and it's using rclone, did some more digging and i see that rclone has a --bwlimit option which seems quite perfect to solve my problem. However GUI settings for cloud sync give no options to provide additional parameters to the process. Does anyone know how could i modify the cloud sync settings... maybe in terminal? I'm on 11.1-U6
