Rclone API - what happens if server dies/reboots?

on the rclone API, when I make a job request for a copy. If the API dies, the machine crashes, rebooted, etc. Does it pick back up or do I need to monitor that the job died resend the request?

Similarly, is there a way to only allow a certain number of async jobs to be run at a time to monitor bandwidth? Or do I have to do that on my side by monitoring the number of active jobs?

You'll need to resend the request

You can set --bwlimit to limit the overall bandwidth.

There isn't a limit of the number of async jobs - there probably should be. I'm pretty sure there is an issue about that.
