I just powered off our Dude Server to move it - when I switched it on again - I have lost everything! No network maps, everything has gone. I try to load my backup file, but there is an error, the connection drops and when I can log back in nothing is there.
Two days work down the drain? 
Has this happened to anyone and can it be fixed?
I dont know if you did this but you have to make sure the dude server is turned off because if you shut off the computer while the server is running it may corrupt the database. Its happened to me a couple times.
I don’t think you can turn off the server if its running under RouterOS rather than Windows. I may be wrong…
I know nothing about dude on the boards. 
It just happened again!!
All my maps are gone - but this time we made no change to the server - it is still running but when I logged in all network maps have just vanished!
Devices are still listed however…
