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.

[Question] Using DD to make a backup of an OS drive? (lemmy.ml)

Would this work or would I have problems:

Using dd command to backup an entire SSD containing dual boot Windows/Ubuntu partitions into an .iso file, with the intent to then dd that iso back onto the same size SSD in the case of a drive failure?

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.
