Analytics Data Retention Policies, Default Retention Policy

By default, the appliance retains per-second data for 7 days, per-minute data for 14 days, and per-hour data for 90 days. However, it is strongly recommended that you specify a data retention policy that suits your business needs. Retention policies are especially important if you plan to retain large amounts of historical data for an extended period. The maximum retention period is two years.

Enabling a Retention Policy

A retention policy limits the minimum amount of data collected by a granularity of per-second, per-minute, or per-hour over a period of time, or retention period. You could set one retention policy per granularity. For example, you could define a retention policy to save a minimum of one day of data at the per-second interval, a second policy to save a minimum of one week of data at the per-minute interval, and a third policy to save a minimum of one month of data at the per-hour interval. It is recommended that you only keep the minimum amount of data according to your business requirements, including compliance needs.
