Hello! I had this huge problem with my windows (I had a dual boot elementary-OS/Windows) and now I need re-install it. To do that I need to make all the partitions again and blablabla, but I worked hard on my GNU/Linux to make it more suitable to me and I don't want to do it all again. So I'm a****g for some tips about backup, I have a disk space to store my entire GNU/Linux system if I need to. I think it will be useful to have a backup of my system stored. I read something about tar, rsync (grsync) and DejaDup but I wanted to hear of you guys about some experiences you had.
