Lately we happen to encounter the partial or complete loss of the project uploaded on LMs (light and Reactor) and Schneider wiser.
It has happened several times during power outages on machines not powered by UPS.
If I'm not mistaken, it should be written to flash memory every half hour or by pressing the "synchronize project" key.
In at least one case, we experienced a TOTAL loss: as if the machine had been reset to factory conditions.
In another case, we lost an entire day of work, NOT the last half hour.
How is this possible and what causes it and, above all, is it possible to make it more reliable?
Thanks
Peppe

Did you have a single power outage or several in a row?

Another LM completely reset after a blackout!
This time the firmware was not the most recent, but 20230307.
The interesting thing is that he lost everything (objects, pages, etc.), except the project on Mosaic.
Have you had the opportunity to do some tests on this unpleasant inconvenience?
We need to know if something can be done or we have to necessarily put the LM under UPS and hope it never fails.
I await your kind reply.
Thank you

This particular firmware had a bug with such outcome. Make sure all LMs are up to date.

I'm afraid nothing can be done. In an unlucky event when LM tries to save project and if power failure happen during this time the data can get corrupted. The SQL db has checks for corruption and if this is reported it will be discarded.
The best idea is to use an ups to prevent such situation. Having a backup is a must.
