Hyperv VM in locked state during Backup

Hyper VM in Hyper-V cluster goes to locked state during NetBackup backup and I understood its the behavior of Hyper-V that lock is not released until the backup completes deleting the snapshot/checkpoint. 

I think its Microsoft that creates the lock due to snapshot accessed for backup, but I didn't get any solid tech references for the same. We are using VSS method for this HYPER-V policy type. Please correct me if I am wrong and let me know if we have option/enhancement from NetBackup for Hyper-V backup so that it doesn't lock the VM till backup completes if NetBackup manages it.

Hello
You said it right. As you understand it’s MS issue so my recommendation is to reachout to MS Support for further investigation and help.
