Automatic snapshot schedule not working

Hello to everyone and thanks to Turnkey for their appliances.

We have a strange problem regarding automatic snapshot schedule in Turnkey Hub: it seems that some schedules are not working at all. For example on an specific instance we have hourly and daily snapshot with different retention but only hourly snapshots are created (and deleted) following the schedule; no daily snapshot is being created and listed.

If we try to create a manual snapshot it seems to work fine. The problem is present in several instances that we have in the hub. I tried to disable and reenable snapshots partially or completely with no success.

What i really don't understand is: who manages the scehdule, can we receive a log?

Thanks in advance and best regards,

LucaIM
