When Home Assistant is creating a backup, there might be a need to pause certain operations in the integration, or dumping data so it can properly be restored.

This is done by adding 2 functions (async_pre_backup and async_post_backup) to

Adding support

The quickest way to add backup support to a new integration is by using our built-in scaffold template. From a Home Assistant dev environment, run python3 -m script.scaffold backup and follow the instructions.

If you prefer to go the manual route, create a new file in your integration folder called and implement the following method:

from homeassistant.core import HomeAssistant

async def async_pre_backup(hass: HomeAssistant) -> None:
"""Perform operations before a backup starts."""

async def async_post_backup(hass: HomeAssistant) -> None:
"""Perform operations after a backup finishes."""
