The DS‑Client accumulates statistical information that can help you to analyze load, utilization, and storage trends.

For new target backup servers, the DS‑Client can perform statistical backups for a few days or weeks to generate this information. These are similar to online backup sets except no data is sent to DS‑System (the data source is scanned, and files are processed for compression and encryption to obtain statistics). You can then analyze the data amounts, trends, and incremental amounts before performing actual backups.

Statistical data is updated automatically during a Daily Admin or Weekly Admin process. If no administrative processes are scheduled, DS-Client automatically updates statistical data daily. You can also update statistical data on demand to ensure that it is available immediately before generating reports.

In production environments, the statistical information accumulates for all backup set types (online, statistical, self-contained, local-only, and instant recovery). These details are presented in reports that DS-Client generates. For more information, see “Working with reports”.
