# Backends > deepagents → Backends Backends control how deep agents store files and manage state. Choose a backend based on your persistence and isolation requirements. > **Learn more:** For detailed guidance on choosing and configuring backends, see the [Backends documentation](https://docs.langchain.com/oss/python/deepagents/backends). ## Classes -
