Nothing about back

Son can you read? Look at the example and change it a bit:

hook.Add( "ScalePlayerDamage", "chestdamage", function( ply, hitgroup, dmginfo )
 
	--Less damage to chest/back
	 if hitgroup == HITGROUP_CHEST then
 
		dmginfo:ScaleDamage( .5 )
 
	 end

 
end

you will need the poss of the player attacking and the target, fetch the eyetrace of the target, check if it is looking away and if he is scale the damage up. and could make it into a meta so you can use it more easily.

uh? Just use the dot product, don't waste your time with ridiculously over-expensive traces. Not really even a point of putting it in a convenience function for such a simple operation.

hook.Add( "ScalePlayerDamage", "backdamage", function( ply, hitgroup, dmginfo )
 
	--Less damage to back only
	if hitgroup == HITGROUP_CHEST then 

		if ( dmginfo:GetAttacker():GetPos() - ply:GetPos() ):Dot( ply:GetForward() ) < 0 then

			dmginfo:ScaleDamage( .5 )

		end

	end
 
end )

edit: If it really tickles your fancy, here's the convenience function:

local Entity = FindMetaTable( "Entity" )
function Entity:IsBehind( ent )

	return ( self:GetPos() - ent:GetPos() ):Dot( ent:GetForward() ) < 0

end

Traces in source are very effecient actually, and I believe a trace from the players eyepos to aimpos is done every frame and cached regardless if it's used (GetEyeTrace()). But the dot product is appropriate to use in this situation.
