I need to pairs 2 tables in this workspace backup script, How do I do that ?

I'm from Brazil, sorry for the English mistakes

print("Server backup by BrennoMaturino1 (I am from brazil)")

local ignore = {
    --Exemplo: workspace.Rocket --[[-- AQUI VÃO OS MODELOS QUE DEVERÃO SER IGNORADOS --]]--


    workspace.Lobby,
    workspace.GameScripts,
    workspace.Terrain
    --workspace. --[[-- NOME DA INSTANCIA --]]--
    --workspace. --[[-- NOME DA INSTANCIA --]]--
    --workspace. --[[-- NOME DA INSTANCIA --]]--
    --workspace. --[[-- NOME DA INSTANCIA --]]--
}
local instances = {} --Não mexa, aqui são armazenados os modelos do jogo com excessão os que devem ser ignorados

function PlayerJoined(player)
    player.CharacterAdded:Connect(function()
        if table.find(ignore, player.Character) == nil then
            table.insert(ignore, player.Character)
        else
            warn("O character do jogador: "..player.Name.." Foi adcionado mas já está na tabela")
        end
    end)
end

function ClearTable(tbl, IsInstance)
    if IsInstance == true then
        for number in pairs(tbl:GetChildren()) do
            table.remove(instances, number)
        end
    else
        for number in pairs(tbl) do
            table.remove(instances, number)
        end
    end
end

function CloneWorkspace()
    if table.getn(instances) ~= 0 then
        ClearTable(instances, false)
    end
    for number, instance in pairs(workspace:GetChildren()) do
        for number2, tableobj in pairs(ignore) do
            if instance ~= tableobj then
                local startclone = instance:Clone()
                local clone = nil
                if startclone then
                    local clone = startclone:Clone()
                end
                table.insert(instances, clone)
            end
        end
    end
end

function RestoreLastBackup()
    for number, instance in pairs(workspace:GetChildren()) do
        for number2, tableobj in pairs(ignore) do
            if instance ~= tableobj then
                instance:Destroy()
            end
        end
        for number, instance in pairs(instances) do
            instance.Parent = workspace
        end
    end
end


workspace.GameScripts.Events.MakeBackup.OnServerEvent:Connect(CloneWorkspace)
workspace.GameScripts.Events.RestoreBackup.OnServerEvent:Connect(RestoreLastBackup)
