The database doesn't do anything of any duration during this process, except update the file headers and the controlfile. It should be almost instantaneous for even large numbers of datafiles. Duration of backup mode is irrelevant. You can (and should) cancel and retry at any time. If it hangs again, check the wait event of the session trying to take it out of backup mode. You are probably stuck on a controlfile enqueue.
