Thank you Christine for looking into this. I am also not aware of any ways to cancel backups or async collections api calls. Agree that to implement this, it would make sense for something like CANCELASYNC to cancel ongoing async calls. I think adding cancelling async calls is a good idea to consider.
As for visibility, you can check async call status by REQUESTSTATUS or check in ZK/overseer/collection-queue-work. I don't believe that backups/ async calls are exposed through metrics.
