I assumed the position from the current controller who was also the Supervisor and was at a point where they seemed to be losing the picture. They called me over to take it. While receiving the briefing a lot was not accomplished and the controller was very behind with multiple aircraft of varying types and speeds needing vectors to the airport. During the briefing the controller who was also the Supervisor informed me to take over and he would remain plugged in. While working everything out for the aircraft inbound Aircraft X was en route north of the field at 2;000 feet. He had requested updates on weather which he was given and he was given deviations north and direct on course when able. As traffic volume increased he maneuvered towards a 2;500 foot Minimum vectoring Altitude. He came within 3 miles of the 2;500 foot Minimum Vectoring Altitude (MVA) while the aircraft was level at 2;000 feet. As soon as it was realized where he was in proximity to the MVA I issued a climb to 3;000 feet.The Supervisor should have asked for help sooner prior to getting into a situation where normally low level IFR aircraft are diverted and put on a vector well before they approach the MVA. The overall transfer of the position should have been conducted in a more appropriate manner and the Supervisor should not have just had the controller take over. Any time there is an IFR aircraft in the airspace below an MVA there should be better care or attention given to that aircraft.
SAV Controller reported that while relieving another Controller observing an aircraft below the Minimum Vectoring Altitude.
