I made an image of 16GB card which is now a 14.8 GB which is exact to the card memory , can we make image with file size used like it is currently using 6GB only.
Can we create raspberry sd card image to only the file size it is using not the complete card size images
I use the following procedure to make backup images.
This can be used to make minimal sized, full size or arbitrary sized images. The prompts for image size on initial backup; subsequent backups update the image.
I backup my 32GB cards to a 13GB image (which can be compressed to less than 5GB for archival).
