Hello,
As a long time Arch Linux user I know how important it is to create a usefull backup, and keep it up to date. Now that I have switched to Manjaro I am glad to share some of my Arch Knowlege with the community. The best way I have backed up my system is by copying the Home directory. This is because with any Linux distro all settings are stored in your home directory, even your program settings like Firefox and Chrome, along with all personal files. In order to do this you will need to run one file manager through the terminal as a root user, and another with standard privileges. to run a root file manager open up a terminal and type
sudo (File-manager_name)
If you use Xfce this will be sudo thunar
as and exaple for kde or any other DE run sudo then the name of either the defult or you preferred file manager; This sould open a file manager with root privliges...It should have a high-vis notification on the file manager that states it is in root.
Now go to your OS dierectories where directorys like bin, usr, and boot are located. Once you find the home directory right click and copy it...or creat an archive
(Warning creaing an archive like a .tar will take a long time but save space!)paste the copy into your external storage device, like USB, SD or, HDD via the terminal with standard privileges; or do the same with the archive but just copy it from the root file manager. If you do not run a root file manager you will not be able to copy the home directory, it will not allow you the premissions and you will reveice a premissions denied error.
Now all you have to do to keep it up to date is re-copy the home directory and replace the old one, if you ever have to reinstall the OS or install another distro with the same DE you can paste the copied home directory into your files and replace the defult one and all you settings and files will transfer over.
Hope this helped, its the easiest way i know of!
