I was just wondering why my system is sometimes somewhat busy in the morning and it occurred to me to that anacron might be something to do with it. This is my desktop system which is left turned on all the time.

So, after digging around a bit I found that anacron gets run (via /etc/cron.d) at 07:30. So anything that takes a while, like a weekly incremental backup, can often be running when I'm using the computer.

What's the reason for choosing 07:30? If the computer is never turned on at 07:30 then does anacron ever get run? Presumably it must get run as part of system start-up otherwise anacron tasks would never be run. So, why not set the default time to 02:30 or something similar so that, if the computer is turned on tasks get run in the small hours?

It's easy enough to change of course and I will do so, but the default seems a little odd.

Chris, your proposed action is of course appropriate. But 07:30 is the statutory time to be starting on your second cup of coffee, which takes longer than the first; so the default time of 07:30 for anacron is quite reasonable! :)
