Symptoms

El respaldo del sistema de archivos falla para el saveset de recuperación ante desastres, pero funciona para las unidades locales en un clúster de dos nodos.

Entorno:
cliente de Windows Server 2019 con el paquete de cliente de NetWorker 19.x instalado

Detalles > del saveset Cluster_Name
del clúster > unidad compartida Q: y CSV (C:\ClusterStorage\Volume1).

Detalles > del saveset de ClusterNode-1
C:\ y DR

Detalles > del saveset de ClusterNode-2
C:\ y DR

 

Cause

Error:

99128:save:Disaster Recovery: critical volume C:\ClusterStorage\Volume1\ identified for disaster recovery backup has been created on a CSV volume. Backup of critical volume on CSV volume is not supported.

Esto significa que alguna aplicación está instalada en CSV, por lo que se considera CSV como unidad crítica.

save -o VSS:LCV=yes no debe enumerar CSV como volumen crítico en los nodos físicos. Si CSV aparece como crítico, el respaldo de recuperación ante desastres falla. En el siguiente resultado (consulte la sección Notas), vea que CSV aparece como crítico en un nodo y en otro, no.

Nota: NetWorker es compatible con respaldos de CSV con las siguientes restricciones:
  • El volumen no puede ser un volumen crítico.
  • NetWorker no puede crear una shadow copy de un CSV ni de discos locales que se encuentren en el mismo conjunto de shadow copies de volumen.

 

Resolution

Elimine la aplicación instalada de CSV.

 

Additional Information

El resultado proviene de uno de los nodos del clúster. Esto muestra CSV como volumen crítico y, por lo tanto, el respaldo funciona para C:\ y falla para el saveset de DR desde este nodo.

C:\Windows\system32>save -o VSS:LCV=yes

99128:save:Disaster Recovery: critical volume C:\ClusterStorage\Volume1\ identified for disaster recovery backup has been created on a CSV volume. Backup of critical volume on CSV volume is not supported.
The following volumes are determined as critical by the system state writers:
C:\ (disk num 0)
The following volumes are critical because they are parents for one or more mounted critical volumes:
The following volumes are critical because they are in the same dynamic disk pack with one or more critical volumes:
The output is from another node from Cluster which doesn't show CSV as critical volume and hence backup works for both C:\ and DR saveset.
