NetWorker: O GLR do Active Directory falha ao restaurar atributos de um objeto que foi movido

O NetWorker Module for Microsoft (NMM) faz backup de objetos do Active Directory (AD). Isso é chamado de backup e restauração em nível granular.  

O problema acontece quando o NMM falha ao restaurar atributos de um objeto que foi movido de seu caminho original do AD para um novo caminho. 

O caminho é o nome distinto (DN) no Active Directory.  

Por exemplo:
 

The restore of Active directory attributes of object "CN=UserNameX" is failing. 
The reason is because this object at the time of backup had a DN like
"CN=UsernameX,OU=OU123,OU=Admin,DC=domain,DC=com"

Some time after the backup completes, that same object is moved in AD to new path like
"CN=UsernameX,OU=Decommissioned,DC=domain,DC=com"


Message:
>>>>    the Object does not exist in the Active directory, so its attributes cannot be restored. please try to reanimate it. 


NOTE
Since the object has not been deleted, it is not present in Deleted Items of Active Directory and cannot be reanimated.

O comportamento do recurso de backup e restauração granulares do Active Directory do NMM e as limitações do Active Directory fazem com que esse problema ocorra.
O NMM pode restaurar objetos ou atributos de objetos que foram submetidos a backup, no entanto, há algumas restrições.

 

Tombstone lifetime restriction—When an Active Directory object is deleted, the object is retained in a Deleted Objects
container or tombstone. If you need the deleted object, you should recover the tombstone object instead of creating a new
object because data, such as the Security Identifier (SID) and the Globally Unique Identifier (GUID), are stored with the
tombstone object. This data is critical for additional data recoveries, such as reclaiming assigned group permissions.

Objects in tombstone are deleted when they reach the tombstone lifetime age for the domain. The lifetime age is 180 days for Windows. 
After an object is deleted from the tombstone, it cannot be recovered. This is an Active Directory restriction.
The tombstone lifetime is a configurable attribute of a Windows domain.

Moved or renamed objects—If objects are moved or renamed, but not deleted from Active Directory, 
those objects cannot be restored even if they are successfully backed up. 
Those objects are not stored in the deleted storage database (tombstone) so they cannot be restored.

• Não mova um objeto do Active Directory para um novo caminho no Active Directory após o backup do objeto. Isso causa falhas de restauração.
• Se as atualizações do Windows não tiverem sido executadas, agende uma atualização o mais rápido possível.  Isso inclui atualizações para o .Net Framework.

• Mova o objeto atual do AD de volta para o local original.
• Em seguida, teste a restauração dos atributos desse objeto.
