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.

The fact that Linux lacks a decent system-level backup tool with a GUI is kind of a mind boggler for me. The best one I've found which gets close to this is timeshift. File-level backups can't restore your whole system state and users shouldn't be expected to remember or manually export their package lists and god knows what else. I have subsisted on file-only backups but it's really not great as a solution. Disks fail, and when they do, you inevitably have to reinstall the entire OS. It's a mess. RAID1 could theoretically prevent this, but no distro makes it easy to boot from a RAID1 setup.
Backing up the entire filesystem is not a technically complex thing, there are plenty of command-line tools to do this and some filesystems even support this concept via snapshots etc. But this has yet to be put into a useful practice for end users.
There is btrfs-assistant, for example.
Look for one without a GUI and learn its command-line, and you're done.
