 **Data Retention and Backups**
-InfluxDB is configured to use a 25-year retention policy (see [influxdb.sql](../influxdb/influxdb.sql)).  It uses continuous queries to downsample Powerwall data and preserve disk space.  However, this does not safeguard the data from accidental deletion or corruption.  It is recommend that you set up a backup plan to snapshot the data for disaster recovery.
