I recently made a post discussing my move to Linux on Fedora, and it’s been going great. But today I think I have now become truly part of this community. I ran a command that borked my bootloader and had to do a fresh install. Learned my lesson with modifying the bootloader without first doing thorough investigation lol.
Fortunately I kept my /home on its own partition, so this shouldn’t be too bad to get back up and running as desired.

    Friendo, I think once you understand exactly what an OS is, you’ll have fewer problems. An OS is just a layer on top of hardware with a lot of scripts and tools that enable that hardware to do things like move files, show graphics, and send audio in a desktop environment. Never issue a root or sudo command unless you understand exactly what it’s doing. Following this one simple rule will save you a lot of trouble, same as any Windows machine.

      And a lot of configuration, or so I thought? I’m investing heavily but I’m scared for my investments :-)

      Another Linux noob here, after a couple of Linux servers (Tenfingers, Lemmy) switched over (finally) my main PC, or well kids got the gaming machine and I’m on a Mint ThinkPad now :-) and a backup think centre tiny if the Lemmy server bails out.

      I have this little windows box to print stuff (I didn’t know I hated printers) and every time I use it I’m so happy I don’t need windows in my personal life anymore…

      Cheers and welcome OP!

          Except that I’m jumping ship to Linux fully, I’m thinking a lot about hardware failure, not the data but say the mobo, so maybe that’s curious. Seemed you were knowledgeable about those things, or I’m explaining very badly.

          Cheers

      This is reasonably valid. I think Windows makes it a bit harder to do real damage to your system, so I’m used to that. I also have borked installs in VMs before, but that’s never mattered because spinning up a new one takes no time. Definitely a valuable lesson to do more research before running commands, especially as sudo

        Nah. This is old school thought. Use an immutable distro if this is your concern, and keep all your files on a NAS, or something else that can replay your files. Local images of your entire filesystem isn’t needed anymore.

            They are two different things.

            A Clone of an OS install is not needed anymore, for a jillion reasons.

            Personal files do not relate to that.

            Perhaps you don’t understand how these are intended to work?

                Heyha ! Read about dd on makeuseof after reading your post, to see how it works.

                Restoring from an image seems exactly what I was looking for as a full backup restore.

                However this kind of 1 command backup isn’t going to work on databases (mariadb, mysql…). How should I procede with my home directory where all my containers live and most of them having running databases?

                Does it work with logical volumes? Is it possible to copy evrything except /home of the logical volumes?
