Hi Gang,

i try to make my first backup with Win32 Disk Imager but i have problem and dont know how to resolve it.
I do it with this steps:

But on the step 5 when i click 'read' button i see error and process stop:
'the disk is not large enough for the selected image'

I have enough space on my hard drive (57GB) and retropie image on sd card have less than 10GB.

What i do wrong ? Any hints ?

What is the size of your sd? 64GB? 128 GB?

@saccublenda 256GB Kingston

@retrus You have 57GB free on your HDD?
Then of course the 256GB Image does not fit on this HDD.
The imager uses the maximum size of the SD-CARD, even if there are only three C64-games stored on it.

Yes, the image that you create will have the same size of the sd, regardless of how much free space it has.

Ok, thanks for fast help Guys @saccublenda @sirhenrythe5th

So if my image with roms have for example have 10GB and its on 256GB SD card, when i make backup in result i have 256GB image or 10GB image ?

Now i know that i must have free space on hard disk like my SD card.
Its possible to make backup from SD card to SD card with Win32 Disk Imager ?

As said in the previous replies, the backup image will have the same size of the sd card, so 256GB.

I guess so, but the target sd card will not be bootable, it will just contain a single 256Gb .img file.

@retrus You may use rpi-clone to clone your card to another, smaller one, and then run the backup on Windows.
