# 'Snapshot' vs 'Backup'
-In August 2021 [the Home Assistant team announced](https://www.home-assistant.io/blog/2021/08/24/supervisor-update/) that 'snapshots' will be called 'backups' moving forward. This addon exposes a binary sensor to indicate if snapshots are stale and a another sensor that publishes details about backups. Both of the sensors used 'snapshot' in their names and values, so they had to be changed to match the new language. To prevent breaking any existing auotmations you might have, the addon will only start using the new names and values when you upgrade if you tell it to.

This can be controlled by using the configuration option ```call_backup_snapshot```, which will use the old names and values for sensors when it is true. If you updated the addon from a version that used to use 'snapshot' in it names, this option will be automatically added when you update to make sure it doesn't break any existing automations.
