I would like an effective software to do system images and restore points like Systemback, it is a very useful software.
Instead of the one installed by default, Deja-dup, that has ruined me some files of Libreoffice.
I uninstalled it and replaced with Backintime, which I use for back up files, in addition to Systemback for system images and restore points on Ubuntu 14.04.
With Systemback you can choose whether to restore only the home configurations, only the file system or both. Also, when you create a restore point, you can choose which files and folders to exclude from it.
@steven , regarding point 10, I solved by putting in the menu ( internet) a launcher for the following script.
echo yourpassword | sudo -S killall NetworkManager
