Symptoms

O backup do file system falha no saveset de recuperação de desastres, mas funciona para unidades locais em um cluster de dois nós.

Ambiente:
client Windows Server 2019 com pacote de client do NetWorker 19.x instalado

Detalhes do cluster > Cluster_Name
do saveset > unidade compartilhada Q: e CSV (C:\ClusterStorage\Volume1).

Detalhes > do Saveset do ClusterNode-1
C:\ e DR

Detalhes do Saveset > do ClusterNode-2
C:\ e 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.

Isso significa que algum aplicativo está instalado no CSV, portanto, ele está considerando o CSV como unidade essencial.

save -o VSS:LCV=yes não deve listar o CSV como volume crítico nos nós físicos. Se o CSV estiver listado como crítico, o DR backup apresentará falha. No resultado abaixo (verificar a seção Notas), veja que o CSV está listado como essencial em um nó e, em outro, não.

Nota: O NetWorker é compatível com backups de CSV com as seguintes restrições:
  • O volume não pode ser essencial.
  • O NetWorker não pode fazer uma cópia de sombra de um CSV e de discos locais que estejam no mesmo conjunto de cópia de sombra do volume.

 

Resolution

Remova o aplicativo instalado do CSV.

 

Additional Information

O resultado é de um dos nós do cluster. Isso mostra o CSV como um volume crítico e, portanto, o backup funciona para C:\ e falha para o saveset de DR desse nó.

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.
