I also very much echo Frank's sentiment to Arno thanking him for edifying 
us as to why some apps can be backed up and others can't (unrooted).

I, like Frank, am not all that interested in the gory details; but it has 
always confused me why some apps and file managers can see the system 
directories on Android while other apps and file managers can't see them.

Specifically I've wondered why I can see a lot of the root system folders 
when I use adb and webdav servers with Windows File Explorer over USB.

If anyone cares, one file manager which *does* seem to see (read only) 
system folders on Android appears to be ZArchiver archival program.
 <https://play.google.com/store/apps/details?id=ru.zdevs.zarchiver>

It's not supposed to be only a file manager - but it shows the root 
partition. 

Maybe Arno can explain why that one archiver shows the file system so well?
Muntashirakon App Manager shows me it has some of the following permissions
android.permission.REQUEST_INSTALL_PACKAGES
android.permission.MANAGE_EXTERNAL_STORAGE
android.permission.ACCESS_SUPERUSER
etc.
