DataStore EXPERT needed!

[FractalVortex]

Hey guys, I’ve been working on a game and needed a datastore. I found a tutorial on YouTube and followed along with it and the datastore works really well. The only issue is that I noticed that when my power went out (while playing my game), when I rejoined, my data was reset. Does anyone know how to prevent data loss like this in the future?

ServerScript:

local dataStoreService = game:GetService("DataStoreService")
local dataStore = dataStoreService:GetDataStore("Player")

local loaded = {}

game.Players.PlayerAdded:Connect(function(player)
	local success, value = pcall(dataStore.GetAsync, dataStore, player.UserId)
	if success == false then player:Kick("DataStore failed to load") return end
	local data = value or {}
	print("Loaded:", data)
	for i, folder in game.ServerStorage.PlayerData:GetChildren() do
		local subData = data[folder.Name] or {}
		local clone = folder:Clone()
		for i, child in clone:GetChildren() do
			child.Value = subData[child.Name] or child.Value
		end
		clone.Parent = player
	end
	loaded[player] = true
end)

game.Players.PlayerRemoving:Connect(function(player)
	if loaded[player] == nil then return end
	local data = {}
	for i, folder in game.ServerStorage.PlayerData:GetChildren() do
		local subData = {}
		for i, child in player[folder.Name]:GetChildren() do
			subData[child.Name] = child.Value
		end
		data[folder.Name] = subData
		folder:Destroy()
	end
	local success, value = pcall(dataStore.SetAsync, dataStore, player.UserId, data)
	print("Saved:", data)
	loaded[player] = nil
end)

game:BindToClose(function()
	while next(loaded) ~= nil do
		task.wait()
	end
end)

Note: I can script a lot of things, but DataStores aren’t one of them. I have no idea how to make changes to the DataStore script without breaking it…

Any help is much appreciated!

I recommend you use a datastore module like Suphi’s datastore or ProfileService since they include support for preventing loss of data. No one really uses DataStoreService on its own like this since there’s no point

You should make it so it saves the data randomly everytime like every minute or everytime when their stats and stuff changes.

Something I did to prevent data loss every time, I actually used a different method.

I made a folder called Player.Name…“Leaderstats” in serverstorage, and then a folder called leaderstats in the folder. Then whenever a value in leaderstats changed, I made it replicate to the leaderstats in serverstorage.

when the player left, the leaderstats could end up getting destroyed before saving, so instead I saved the ServerStorage folder which would always be there, and then destroyed it. Using this method I have never lost data in my game.

Thanks for all your responses. I’m going to use @cherrypathy idea since I think it will be the easiest thing for me to implement without having to make tremendous changes or have to completely rescript the system.
