You might consider the following directories when doing your system backup:
/root
• main directory for the root user.
/home
• contains the user’s data files and user-specific configuration files. Each users has one folder with their username. Each user only has write access to their own home folder and must obtain elevated permissions (become the root user) to modify other files on the system.
/etc
• contains system-wide configuration files, not contain user-specific configuration files (normally located in each user’s home directory).
/usr/local/
• locally compiled applications install to by default (i.e. not installed through apt). If you have packages installed here, you may want to backup the whole directory, so you don't have to reinstall them. If the packages themselves aren't important to you, it should be enough to backup /usr/local/etc/ and /usr/local/src/
/boot
• contains the files needed to boot the system – for example, GRUB boot loader’s files and Linux kernels are stored here. However, the boot loader’s configuration files aren’t located here, though – they’re in /etc with the other configuration files.

Well, if you're restoring the files after a re-install you shouldn't restore the
/bootdirectory. About the/etcdirectory I'd manually restore just specific files...Downvoting a post can decrease pending rewards and make it less visible. Common reasons:

Thanks for your time to comment on this, I include the /boot directory because some users with dual boot may need it. I agree that some files in /etc directory are unnecessary but it'd be difficulty for inexperienced users (including me) to select them one-by-one, so to save more time I'd just save & restore the whole directory. Please share your opinion here if you have one :)
