Hi Tommy,
the current implementation reflects what is in the Quick Specs. The CBL usage terms did not change since introduction in Data Protector A.07.01. When the CBL report was added in A.09.02 I had customers showing permanently 0TB while several TB where actively backed up. Now everything is fine, with a few exceptions (server migration scenarious where new objects are added to IDB) pointed out earlier. Here is something you could try. Run BRICK with advanced reports enabled. This gives you an external backup volume estimation. Please let us know the discrepancy. Calculating this manually is a pain.
Capacity calculation details: For a full & incremental backup concept, only full are considered For an incremental forever, a "synthetic" full is used Only objects with a status of “completed” or “completed with errors” are included in the calculation Only objects which are still under protection are included in the calculation The capacity per system is calculated as an aggregation of the largest size of each unique object for that system still under protection
