Where or how to find my data

Post by vy1xy »

I would like to back up my data and then use it to move to the new Cumulus. I can only find one year of data but the cumulus will show all years. What is the name of the file/format so I can try and find it.

Hi,
In the folder where you have Cumulus.exe you will also have a \data subfolder with all the Cumulus data files.
That same folder where Cumulus.exe is also has a \backup folder and that will contain the 10 most recent daily backups and 10 recent backups from when Cumulus.exe was stopped.

Enjoy,
Paul
