we are using NetVault 12.1 to backup all virtual machines from our hyper-v 2012R2 cluster.
vms01 (node1) vms01 (node2) vmscl (cluster). Ping, nslookup/ptr, check access, firewall test is running successfully.
For some weeks we see the following messages in the backup log.
Job Message 2018/10/29 18:00:02 71 Data Plugin VMS01 Number of VMs selected for backup: 20
Error 2018/10/29 18:00:05 71 Data Plugin VMS01 VM [BI01]: Failed to find VM on cluster 'VMSCL'
Error 2018/10/29 18:00:06 71 Data Plugin VMS01 VM [BI01]: Backup failed

Error 2018/10/29 18:00:10 71 Data Plugin VMS01 VM [CLOUD]: Backup failed
Here is what I did to get it running again:
- Removed all agents on vms02, restart
- Deleted virutal client
- Created new virtual client with the cluster name "vmscl" (agents are installed on vms02 successfully)
- Hyper-V Cluster license is looking good
- Running the following commands
Remove-ClusterNode -Cluster vmscl vms02
Add-ClusterNode -Cluster vmscl vms02
Get-ClusterNode -Cluster vmscl
Name ID State
---- -- -----
VMS01 2 Up
VMS02 1 Up
Virtual machines running on vms02 are still not backing up / shown in the create backup selection section.
