Backup picture using FreeFileSync I would like to backup my pictures using FreeFileSync, I say pictures because i want to migrate both iPhoto and photos libraries till i figure which one i want to keep

I have my reasons not to use TimeMachine

So with FreeFileSync which folder should i be selecting as the folder to sync?
To back up photos visible in Photos.app and iPhotos.app, select the folder: 

~/Pictures/


Where ~ is your home folder.
