how to clone microsd card data only

[peter12]

Hello, 

this question is not armbian specific but I am dealing with it while using armbian. I have 8GB microsd card but my armbian is using just 1.5GB on it. Now I need to clone/copy this card. I use win32diskimager (on windows) but disadvantage this approach is, that it makes bytedata image file (all 8GB of the whole microsd card even with blank space) but my data have 1.5GB only. 

 

Is there any utility/software which makes image with 1.5GB only? I mean when I burn 8GB image size after that to another microsd card, it takes 5x more time to finish as if I could burn just 1.5GB image. I think it must be able to do it somehow, because armbian images has about 1.5GB only. Any help will be highly appreciated.

You could resize the partition with gparted, but I don't know if is there an equivalent that runs under windows.

Moved topic, cause nothing to do with hardware/software h3 specific..

Depending on options at image creation time it can be even a lot lower. We calculate the size with some safety headroom in mind before putting partitions on the image: https://github.com/armbian/build/blob/master/lib/debootstrap-ng.sh#L308-L333

Maybe, you could write a little tutorial about your procedure here? So that other might benefit from it?
