NetWorker: Sikkerhedskopiering efter nedbrud af klynge mislykkes i passiv node

Sikkerhedskopiering af filsystemet mislykkes for saveset til genoprettelse efter nedbrud, men fungerer for lokale drev i en klynge med to noder.

Miljø:
Windows Server 2019-klient med NetWorker 19.x-klientpakke installeret

Oplysninger om klynge > Cluster_Name
Saveset delt drev Q: og CSV (C:\ClusterStorage\> Volume1).

ClusterNode-1
Saveset-detaljer > C:\ og DR

ClusterNode-2
Saveset-detaljer > C:\ og DR

Fejl:

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.

Dette betyder, at nogle applikationer er installeret på CSV, derfor overvejer det CSV som kritisk drev.

save -o VSS:LCV=yes bør ikke angive CSV som kritisk diskenhed på de fysiske noder. Hvis CSV er angivet som kritisk, mislykkes DR-sikkerhedskopieringen. I nedenstående output (tjek afsnittet Noter) skal du se, at CSV er angivet som kritisk på en node, og fra en anden er det ikke.

Fjern det installerede program fra CSV.

Outputtet kommer fra en af noderne i klyngen. Dette viser CSV som kritisk diskenhed, og sikkerhedskopiering fungerer derfor for C:\ og mislykkes for DR-saveset fra denne node.

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.
