dd Utility - Write and Backup Operating System IMG and ISO files on Memory Card or Disk

There are several tools available to copy and install IMG and ISO files to memory cards and removable storage, but I was looking for something that could easily backup and restore disk image files for my Raspberry Pi, as well as create bootable Linux installation USB drives from ISO's with OS X as well as Ubuntu.

I also wanted a program that could write compressed IMG files directly to the memory card without the need to decompress the image files first. dd the command line utility has been my default choice for years, but lacked a GUI that fit my requirements and so I decided to write my own - that is how dd Utility came to be.
