Handling worst-case scenarios with DataStoreService?

Question

Suppose a player's data is saved upon leaving. After retrying many times (5 times or more) to save their data via DataStoreService, the data still fails to save. What should I do? Cross my fingers that this never happens? If anyone else has taken into consideration this problem, have you taken any precautions for a situation like this? I'm hoping to get several potential workable solutions since to me it seems that there's no cure-all for this problem.

Here's some fake code modeled after the real code I'm using if needed:

function SaveData(params)
	local success, value = pcall(function()
		DataStore:SetAsync(params.key, params.value)
	end)

	if not success then
		warn('could not save data')

		-- still some attempts left
		if params.attempts > 0 then
			wait(params.retryInterval)
			params.attempts -= 1
			return SaveData(params)

		-- data could not be saved after exhausting all attempts
		else
			return false
		end
	else
		-- data was saved, return true
		return true
	end
end

Players.PlayerRemoving:Connect(function(player)
	local success = SaveData({
		attempts = 5,
		retryInterval = 3,
		key = player.UserId,
		value = player.Points.Value
	})

	if not success then
		-- what now?
	end
end)
