Did some testing in Linux. I tried various 1:1 copy utilities. Even dd.
I was able to backup the SD with dd but writing it back on another sd and using that image ist resulting in bootloop. Sorry.

Steps with dd:
dd if=/dev/sdc of=/home/user/pb626_image.dd bs=512 conv=noerror,sync
CHANGE SD and copy back to new sd:
dd of=/dev/sdc if=/home/user/pb626_image.dd bs=512 conv=sync,notrunc

But size of the SD from the PB626 was 3,7GB.
My 4GB SD cards were slightly smaller (3,67/3,69) or much bigger (8GB).
