rsnapshot every 2 hours

Hi

I have rsnapshot configured to keep 48 hourly, 14 daily, ... jobs
unfortunately I nearly get no daily jobs, because checking the difference what to update takes >1h, so most of the time rsnapshot stops "PID file exists and so does process" or something like that.

if I change the openmediavault-rsnapshot file in the hourly line from
5 * * * * root /var/lib/openmediavault/cron.d/rsnapshot hourly
to
5 */2 * * * root /var/lib/openmediavault/cron.d/rsnapshot hourly
it should run every 2 hours.

So there are 2 questions
1) will my manual settings be overwritten more or less "automatically" by any action (i.e. adding another job in the GUI)?
2) Could (eventually, perhaps, please, some days, may be ) this be set by GUI so no need to manual change (which could be overwritten)?

And _IF_ something is changed in the GUI, could there be an option of verbosity level? So we do not get 23 emails a day of successful execution and oversee the 1 with the warning/error

This would be great!

ok - thanks for your effort. I will use email filter and keep and eye on the emails the next hours...
