Data Parts Missing (code 2500)

Situation

A backup plan terminates with the following warning:

Data parts missing. One or more data parts are missing on backup storage for restore point: (restore point name). This restore point and all following restore points may not be restored properly. A full backup was executed and a new generation was created.

Cause

This warning is generated by a mandatory consistency check that is performed at each start of the backup plan. The consistency check detected that some data is missing on backup storage in the current generation (a chain of full and subsequent incremental backups). The restore point with missing data is displayed in the warning message and is marked as invalid along with all following restore points.

Solution

If a mandatory consistency check detects missing data parts on backup storage, it invokes a full backup automatically. Once the automatic full backup run finishes successfully, if necessary, you can proceed to remove invalid restore points manually to free up backup storage space.
