Course backups are currently running at 2am, what should I schedule Server Scheduled tasks 'Automated backups' to be?
Running it every minute seems like a bad idea as the overhead appears to be enormous and unneccesary, 2500 course checks occur every time the cron job runs, cron logs explode in size, only 500 courses are not hidden and to be backed up.
I've set 'Automated backups' to run 155am-205am, to trigger the automated course backup at the appropriate time and keep overhead down.
Can anyone else provide better guidelines when choosing 'Automated backups' setting, my logic above seems kinda weak?
Should I set it to only run once at 2:01am? Is there any benefit to running it multiple times a day? If I run it multiple times a day, ie once an hour, will that ensure all unhidden courses are backed up in a day (I'm still trying to figure out why a few courses sometimes do not backup in the first run but will in the second run.)?
Thanks
