[SOLVED] Backup schedule understanding problems

Jun 29, 2020
I unfortunately have major understanding problems with the scheduler.
Even though tehre is an article
12,14,16,18,20,22:5 equals 12/2:5 and means Every day starting at 12:05 until 22:05, every 2 hours
I wanted to do this similarily

8-17:30 every 2 hours.
so 8:30, 10:30, 12:30

But /2 also means minutes. So the backups stsarts every 2 minutes.
If i say 8..17:30/2:5, so the 2 hours are set with minutes instead of omitted PVE says unable to parse calendar event.
I tried 120 for 120 minutes, but that is not allowed either.

I also tried
that should be 8:00, 10:30, ...
parameter verification failed

Point is, I want my servers to backup as follows

VM 100 8/10/12/14/16
VM 101 8:30/10:30/12:30/14:30/16:30
VM 102 9/11/13/15/17

But instead in the night they are running wild and are backupping every 2 minutes
Th plan ran last nightfor instances at 4:25 4:26, 5:29, 5:32 and many many more.

maybe someone can help me schedule that correctly

So it seems it is not much of a misunderstanding
it looks like the field itself gets trimmed by the webinterface.
2:00 and 2:01 seems to be interpreted as /2

I will apt upgrade and report back

Yeah that did it.
7.1-6 > 7.1-10 and it works as intended.

thank you
