pdregistry.cfg errors (Event ID 33) appear in the Application Event log after deleting and removing the Deduplication Storage Folder.

Problem

If the Deduplication Storage Folder is deleted in the Backup Exec Gui (Storage tab) and the BackupExecDeduplicationStorageFolder directory and subdirectories are also deleted, then the following error message appears approximately every one second in the Application Event Log:

CreateFile X:\BackupExecDeduplicationStorageFolder\etc\pdregistry.cfg: The system cannot find the path specified

Where X denotes the volume the deduplication storage folder resided on.
 

Error Message

Event ID 33 messages appear in the Application Event log as follows:



Details of the Application Event:

CreateFile X:\BackupExecDeduplicationStorageFolder\etc\pdregistry.cfg: The system cannot find the path specified.
 

Cause

Deleting the Dedupe storage folder also stops and disables the following three services:

Backup Exec Deduplication Multi-threaded Streaming Agent
Backup Exec Deduplication Manager
Backup Exec Deduplication Engine

However, the Backup Exec Open Cloud Storage Daemon service is left running. After the BackupExecDeduplicationStorageFolder directory and subdirectories are deleted, this service still attempts to access the pdregistry.cfg file, which causes the above error to appear in the application event log. 
 

Solution

Stop and disable the Backup Exec Open Cloud Storage Daemon service. No other side-effect will be observed from this action as this service is only used in connection with the deduplication functionality.
