      It’s a little bit off-topic to MM2, but don’t you juggle with your Raspis, SD-cards and images you made for backup? And sometimes, you want to restore a backup on a smaller SD-Card? I found a solution in the Internet, the script Pishrink reduces the size of images by deleting unused space and that within minutes. After the procedure, a (for example) previous 64GB image will be much smaller and can be copied to a much smaller SD-card (which is done by windiskimager faster than the original size, of course). Pishrink adds a parameter which expands the file-system automatically to the whole space on the SD during restoring.
      You need Linux if you want to give it a try. If you use VirtualBox, please keep in mind that you can’t run Pishrink at the shared-folder, please copy the image into the VM first .
      For LibreELEC and OpenELEC you need to use the switch -s…please use Google for more information.
      You can find it here: https://github.com/Drewsif/PiShrink

      …I’m not the developer!

          @assassins Did you include a zip-process? If the backup is zipped, you can save additionally a lot of space.
