Hyper-V Image backup fails in Networker : Reason: Saveset contains VM with shared disk.

Hello everyone,

We have 4 guest VM's configured as cluster and while trying to backup those VM's as Image backup in our Networker backup server, the backup operation fails with the following error

"Savesets requested from NMC for backup = 2
APPLICATIONS:\Microsoft Hyper-V\ACEVS077
APPLICATIONS:\Microsoft Hyper-V\ACEVS078

Savesets included for backup = 0

Savesets Succeeded = 0

Savesets Failed = 2
APPLICATIONS:\Microsoft Hyper-V\ACEVS077, - Reason: Saveset contains VM with shared disk
APPLICATIONS:\Microsoft Hyper-V\ACEVS078, - Reason: Saveset contains VM with shared disk "

 

Please could anyone help to understand the issue and any resolution to backup those VM's as Image backup.
