Disable Time Machine reminder on Mac

While giving a presentation in Keynote for a job interview, the presentation suddenly exit and I got a Time Machine message telling me that the last backup was more than x days ago, which was very bad timing. Is there a way to disable this reminder? I can see from the menubar icon whether Time Machine thinks I should do a backup (from the ! symbol) and I don't need an additional reminder that interrupts presentations... Any ideas?

Solution 1:

I think by clicking on the time machine logo in the menubar and opening time machine preferences and turning off hourly/daily backups it will stop the messages
