How to start in safe mode

I need to reset my user profile but first have to back up my user profile and start up in safe mode. How do I do that


Care (meaning backup) should always be maintained when dealing with the user profile. It contains many of your personalized settings. See LibreOffice user profile for further information.

Restarting in safe mode is done through the menu. Help->Restart in Safe Mode....

These two items are somewhat redundant.
