yes,&lt;br/&gt;
if you just remove the power supply without a graceful shutdown - yes&lt;br/&gt;
for both retains on sd or other media the only solution is to have an UPS.&lt;/p&gt;

the message is:&lt;br/&gt;
If you want to use retains on raspberry you need a UPS, which triggers a proper/graceful shutdown of the&lt;br/&gt;
Linux system.&lt;br/&gt;
