How to cancel anacron jobs delayed for a certain length of time?












0














Background: I want to backup some files on my laptop on a daily basis, and there are times when the laptop is shut down for several days in a row.



I tried scheduling the backup as a cron job and use anacron to execute missed jobs, but was not sure about the way anacron works.



If, for example, I start the laptop after a 3-day shutdown, will anacron execute all 3 missed backup jobs? If this is true, what is the best way to stop anacron from executing jobs delayed for a certain length of time (> 1 day in this case)?
