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.

Just to throw another option out there,
partclonewill only copy data that is being used in a partition, without all the empty space. I don't believe it helps for encrypted partitions, but you could always just image the unencrypted filesystem withpartcloneto a drive with full disk encryption to work around that (and still prevent storing data unencrypted). Saves a lot of space.Also, in the context of backups, I often prefer to use
btrfs sendto create and update backups through snapshots quickly and efficiently instead of imaging (though of course that requires you to use btrfs). Full imaging is pretty inefficient for my needs, and takes a lot of time.
