Data retention in InfluxDB Cloud Dedicated
InfluxDB Cloud Dedicated enforces database retention periods at query time. Any points with timestamps beyond a database’s retention period are filtered out of query results, even though the data may still exist.
Database retention period
A database retention period is the duration of time that a database retains data. Retention periods are designed to automatically delete expired data and optimize storage without any user intervention.
Retention periods can be as short as an hour or infinite. Points in a database with timestamps beyond the defined retention period (relative to now) are not queryable, but may still exist in storage until fully deleted.

Use the influxctl database list command
to view your databases’ retention periods.
When does data actually get deleted?
InfluxDB routinely deletes Parquet files containing only expired data. InfluxDB retains expired Parquet files for approximately 100 days for disaster recovery. After the disaster recovery period, expired Parquet files are permanently deleted and can’t be recovered.
