Saving Multiple Tools of the Same Name

[VolcanicsDev (Volcanics)]

This script saves the players tools in a datastore, but if you pick up multiple of the same tool, you will only return with one.
How would I make this script save the amount of a certain tool you have, so for example, if I pick up 2 swords, I’ll rejoin with 2, not just 1.

local ToolFolder = game:GetService("ReplicatedStorage"):FindFirstChild("Items")
local DataStoreService = game:GetService("DataStoreService")
local SaveData = DataStoreService:GetDataStore("SaveData")

game.Players.PlayerAdded:Connect(function(Player)
	local ToolData = SaveData:GetAsync(Player.UserId)

	local Backpack = Player:WaitForChild("Backpack")
	local StarterGear = Player:WaitForChild("StarterGear")

	if ToolData ~= nil then
		for i,v in pairs(ToolData) do
			if ToolFolder:FindFirstChild(v) and Backpack:FindFirstChild(v) == nil and StarterGear:FindFirstChild(v) == nil then
				ToolFolder[v]:Clone{}.Parent = Backpack
				ToolFolder[v]:Clone{}.Parent = StarterGear
			end
		end
	end

	Player.CharacterRemoving:Connect(function(Character)
		Character:WaitForChild("Humanoid"):UnequipTools()
	end)
end)

game.Players.PlayerRemoving:Connect(function(Player)
	local ToolTable = {}

	for i, v in pairs(Player.Backpack:GetChildren()) do
		table.insert(ToolTable, v.Name)
	end
	if ToolTable ~= nil then
		SaveData:SetAsync(Player.UserId, ToolTable)
	end
end)

For anyone potentially wondering in the future, I just found this script that really helped me out:
