Changing Cron Times - any issues?

Chris Musty's picture

Hi,

I need to adjust my cron times due to the length of time it takes to TKLBAM changes to a file system.

Essentially I want to kick things off at about 9PM rather than the 6 am that daily, weekly and monthly cron jobs are set for.

This isn't a question of how to do this but of will this affect anything? - updates, patches etc.

I have modified cron times before without issue but that was a familiar system (Ubuntu). I am aware these images are based on Ubuntu but there are several changes and hey it does not hurt to ask.

I don't think it would have a negative impact on anything but if it were up to me I would choose to only change the tklbam backup time.  I'd move the /etc/cron.daily/tklbam-backup script somewhere else like /root/tklbam-backup so cron won't automatically run it.  Then just add a line to /etc/crontab that calls the tklbam-backup script for whatever time you want.

I might just do that.

I tried the 9pm thing as a test anyway.

Lets see what happens.
