What Happens to Historical Data?
Backup Manager operates differently from other products. Refer to Criteria for Determining Licensing Limits to determine the conditions under which backup clients are counted against your license. Typically, a client must be part of a backup policy or it must have been backed up recently, usually in the last 48 hours.
Since Backup Manager involves transaction-based data rather than just object metadata, when an object is excluded from data collection, these time-sensitive transactions are retained for historical reporting.
All Other Licensed Modules, such as Capacity Manager and Virtualization Manager, do not keep historical data when objects are permanently deleted from the reporting database. See Removing Objects from the License Count and Deleting Objects using the Inventory List View.
