The error:

Found negative value of storage size on ds-system. Protected Size: value, Stored Size: -value, Native Size: 0)

Will normally point to (SysID: *, BoxID *, SetID *.

The BoxID referring to DS-Client Number and SetID referring to backup set ID.

This will help identify the backup set in question.


This error is reported since a backup or other activity for that backup set has been interrupted and DS-System could not update the statistics properly.


Once identified the backup sets, start a system admin ( in ds-operator right click on that backup set > system admin). DS-System will check and detect the invalid stored size and will fix the number.

Once completed, go back to the DS-Billing GUI and run synchronization task on the DS-System in question and the issue is resolved.
