In Veeam ONE Settings utility, review and change retention settings.
It is recommended to make the retention period for events 3 months or less, as events data take up a lot of space in the database. The retention period for virtual infrastructure and backup performance data is normally set to 6–12 months.
Decreasing the default retention values helps maintain a lower size of the Veeam ONE database, but results in reducing the period for which performance and events data is available in Veeam ONE Monitor and Veeam ONE Reporter.
- In the menu on the left, click General.
- Open the Retention Policy tab.
- Specify for which period virtual infrastructure performance data, backup infrastructure performance data and events data must be stored.
- Click Apply Retention.
- In the displayed dialog box, click OK to restart Veeam ONE services.
