The Industrial Raspberry Pi Forum

When I follow the tutorial on this page :

https://revolution.kunbus.com/tutorials ... ng-images/

I see 2 new drives appear when running RPi Boot.

One drive I cannot open in explorer, the other one I can.
The one I can open is only 42 MB big of which only 18MB is used.
The last one is called "boot".

now which new drive I have to backup now?

edit : ok, stupid me : I did not read the tutorial well =>

Select your ReviPi Core in the drop-down list. Shown will only be the drive letters for selection. If you no longer know what it was then look it up in Explorer. Your RevPi Core can be found under “Devices with Removable Media”. It will be shown as “boot”.

so question is answered

But when I backup this drive, it becomes an image of around 30 GB. Is this correct? I expected only about 4 GB?!?

Hi stevennoppe, well without deeper explanations for me it always worked with the drive letter that has the label "Boot". I also get more than one drive letter but I have never inspected it deeply. Maybe someone out of the RevPi or RaspberryPi community may be able to explain it deeper.
