Data retention rates for Data Repository are manageable. The default data retention rates in Data Repository are set to conserve the disk space and improve reporting for most users. Polled data is generated every 5 minutes by default for a given device, and this data represents the most granular data available in the product. This raw, polled data is set to roll up at an hourly interval. The rolled up data is an aggregation of polled values, which provides a higher level, less detailed view in reports. Daily and weekly rollups can be kept longer than polled or hourly data because they require less disk space to store.
However, you can change the rate at which Data Repository retains the polled data, hourly rollup data, daily rollup data, and weekly rollup data. For example, you can change the polled data retention value to 30 days to conserve disk space. Find the balance that best suits your needs and environment.
Note: For information about how to change data retention rates, see the REST Web Services Guide.

Note: If you upgraded to this release from a previous release of Data Aggregator, the polled data retention will not change from the prior default of ten days.
The minimum number of days that Data Repository can retain data for is as follows:
