# ERROR: 	THE MAIN SCRIPT IS NOT WORKING THE $CURRENT_USER VARIABLE DOES NOT GET THE RIGHT USER. 
#			A SIMPLE FIX HAS BEEN IMPLEMENTED.
# DESCRIPTION:
#			Expected Description: IF logged on the main USER then not full sync. if loged on other USER do full sync. 
      This is a hack. actually i wanted to do syncronize a hard drive, but if it is use it is not possibly to syncronize
      everything, so i log from a live image to syncronize the Full hard drive.

# IMPLEMENTATION:	-If not logged on main hard INTERNAL_DRIVE then full sync
#			-Save the last 3 synchronizations or save by date... 'save the syncs of the last X days'
#			-Add the date of the synchronizations
