Anything to improve on my datastore saving?

Help and Feedback Scripting Support
#1 
local function try(data,key)
	local succ,err = pcall(function()
		PlayerData:UpdateAsync(key,function(oldData)
			return data
		end)
	end)
	if (succ) then
	print('updated')
		return true
	elseif (not succ or err) then
		PlayerData:SetAsync(key,data)
		print('save')
				return false
	end
end

Is there anything to improve?
This is how I call it:

local t = 0
	try(dat,p.UserId)
	repeat
		local result = try(dat,p.UserId)
		t +=1
		warn(result)
		wait(.4)
	until t > 3 or result

I want to prevent data loss!
