Seeing that makes me wonder if the schedule changing approach would be easier – though maybe not easy, and arguably something of a (legitimate) special case compared to making stops work better in all situations.
I don’t know who knows the scheduler well besides the very busy original author, but one request was below:
Add ability to skip missed scheduled backups #3251 although I’m not sure the idea of using an option is best because who wants to, or knows to pass in special options? A GUI interaction might be nice, but would have to present itself in some pause time before missed job starts, as after that, we’re back to the fast stop issue.
How to clear the Duplicati scheduler queue is a similar wish, although it was opened in How-To not Features.
Feature request: Skip next scheduled run #3487 began as a limited request, but next user expanded on that.
