It depends on what you've set up.

For the systems I have, I only back up the configuration files in /etc/
plus the output of
    dpkg --get-selections
The restoration plan is to do a fresh installation and restore with
    dpkg --set-selections


Then for the data, it is /var/ and /home/, with special treatment for
any live databases if needed. I don't use /srv/ or /opt/ for anything.

See "man 7 hier"

"""
  /run   This  directory  contains information which describes
    the system since it was booted.  Once this purpose
    was served  by  /var/run and programs may continue
    to use it.


  /srv   This directory contains site-specific data  that  is
    served by this system.


  /sys   This is a mount point for the sysfs filesystem, which
    provides information about the kernel like /proc, but
    better structured, following the formalism of kobject
    infrastructure.
