What to include in a backup? (Ubuntu)

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.

Yes but be careful with that option because it depends how it's implemented by each tool. Some of them will not cross btrfs subvolumes for example.
Yeah, I think I can see some other funny cases if there's multiple partitions with separate filesystems on them. Just doing the regular tar/rsync with exclusions is likely safer as it would work for either case.
