From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You'd probably be better off with dd if=/dev/zero of=file.zero to zero out empty space, dd copy the whole drive, then compress the copy. I wouldn't fuck around with partitions on something I want to back up
For sure, but in my case I didn't want a copressed copy, I wanted a working fully functional drive image
Probably safer to image the whole partition then shrink the image, then. Not sure exactly how I'd go about it, but I'm sure it's not too bad, probably three arcane shell commands
Yes, zero spacing and compress. In my case I was building a direct clone backup for when nas might fail and I can swap drive innediately, but did not want to wait hours to dd the empty drive to an image file.
