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.
Also yes.
I used to do this backing up my "servers". By that I mean some Raspberry Pis and random old PCs running Debian. I even did so successfully when needing to restore the images. But it was fragile and also failed at times, sometimes to great inconvenience when it was a machine serving something important.
I've since moved to a different backup strategy for servers, but if I were to do this with a bare-metal machine I want to preserve, I'd use something like Clonezilla. The maintainers of that project know a whole heck of a lot more than I do of the ins and outs of disk management, backup, and restoration than I do with my simple
ddcommands. If it is something you're just wanting to do for fun and experience,ddcan work. If you're concerned with the security of your data/image, I'd use Clonezilla.As you seem to know a lot about Clonezilla, I’m allowing myself to ask you something.
Would Clonezilla work for doing a backup and reinstalling it on a completely different device?
I’ve already used it to backup and restore on the same device. I also tried to install my Surface Go device backup on an old Acer Computer but it failed to boot afterwards. I’m not sure if it’s because of the surface specific kernel or because it doesn’t work from one computer to another.
Would you know that?
I don't know off the top of my head. I think that Clonezilla can modify images in such a way as they can be booted on a different type of device. My knowledge of the black magic of boot sectors and partition stuff is lacking. Also, you'd have to make sure the motherboard/BIOS is properly configured for reading the device in the same way that the original device was read. UEFI/BIOS stuff can be a pain in the ass to get right.
So my short answer is probably, but I wouldn't be able to walk you through something like that. Wish I could be more helpful.
Okay thanks for the answer 🙏
