Error Message

Unable to create the deduplication disk storage.

The volume where Deduplication Storage folder can be configured successfully, has the following permissions. Use icacls tool and confirm the drive has appropriate permission. If it is not the case, the Deduplication storage folder creation may fail.

E:\>icacls j:\
j:\ BUILTIN\Administrators:(F)
    BUILTIN\Administrators:(OI)(CI)(IO)(F)
    NT AUTHORITY\SYSTEM:(F)
    NT AUTHORITY\SYSTEM:(OI)(CI)(IO)(F)
    NT AUTHORITY\Authenticated Users:(M)
    NT AUTHORITY\Authenticated Users:(OI)(CI)(IO)(M)
    BUILTIN\Users:(RX)
    BUILTIN\Users:(OI)(CI)(IO)(GR,GE)

Note: J is the drive where the Deduplication Storage is being configured in the above example.

If the permissions are not set as shown with the icacls output, modify the drive permissions from volume properties and add the Group or usernames and its respective permission (Allow) to the Security tab.

Consult Microsoft documentation to modify permissions according to the version of Windows. 

Note: If Deduplication Storage configuration still fails, browse to the Backup Exec Deduplication Storage folder path\Log folder and review the errors in pdde-config.log. Contact Technical support if the issue cannot be resolved by the suggestion in this Technote.
