Gaps in historical data

[Leon]

I need some help please.
There appears to be a problem with saving my historical data.
I have a micro usb in the front port formatted as FAT32.
But then every day in my historical minute data gaps appear wich I cannot explain.
The meteobridge pro is uploading all perfectly to other sites and those areas with gaps appear perfectly in for instance my meteotemplate website graphs
I include a couple of screen sots to best explain this.
Any help would be much appreciated….
Kind regards,
Leon Rossouw.

I can't say what had happened exactly, but per minute data is just stored in a RAM database.
When MB PRO does a reboot, the RAM database is stored on USB and reloaded on new boot, but
if you have a power outage, that won't happen. So there could have been a regular reboot
at 8:00 having the RAM database backuped. Then there was normal operation until 12:00
when a hard power-cycle did happen that did not result in storing the RAM database and when
MB PRO reboots it just got the old RAM database backup just holding data up to 8:00.

Per hour data is always made persistent in the USB database and by that immune against power offs.
