Backing up is a subject that I have avoided like the plague (for what reason, god only knows; so, no-one knows)
Same story here. For some reason, for many years the word “backup” was scaring me. Probably because there’s no good and/or easy to use backup tools in win world.
(Unless clonezilla or fsarchiver are very intuitive to use.
Clonezilla is mainly a standalone tool, in a form of LiveCD (though I’ve put it on LiveUSB). Just boot from it and follow its menus. It’s written by the guy from Taiwan, and his English is a bit hard to understand sometime. But nothing tragic.
Clonezilla is a kind of a mission-critical tool. If you just bought a new PC with win8-10 preinstalled and wish to try out a Linux on it, on a clean disk, without windowz, then Clonezilla is your best friend. Make a whole disk backup of original disk, with windowz on it, with CLonezilla, wipe windowz out with gparted, do whatever you want on a clean disk.
If you decide to turn back to original win8-10, just let Clonezilla to restore it from the backup made previously. You’ll get the “origianl” PC, as it was shipped from the factory.
Fsarchiver is more flexible than Clonezilla. If you have many computers, install some Linux on one of them, and want to copy it on your other computers, without changing their partitioning, than fsarchiver will do this job excellently.
Fsarchiver is included, as a package, in all distros I know. Its usage is not harder than those of any Linux command. It has the excellent built-in help. It checks your commands so rigorously, that it’s almost impossible to make an error with it. It simply won’t run. Fsarchiver is so flexible that I simply love it and use it in 99% of cases.
Both clonezilla and fsarchiver have teached me to not be scared by the word “backup” anymore. Now I can’t imagine how it could be possible to live in Linux without backups.
