Hyper V Backup Failing

Also forgot to ask you,

Did you install Integration Components in the VM's? If not please install the same IC version as in the Hyper-V nodes.

If you did please ensure you have installed the same version as the Hyper-V nodes.

Thank you,

Carlos

Hello @Kaiser_Kamal

I read the post but i'm not secure if the issue was solved, actually i have a cluster with two nodes and on the node active that is epmvs13-01 show me the next messages in nmm.raw. I will like know if you have any solution

EPMVS13-02.CORP.EPM.COM.CO : Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

and

ERROR:Microsoft Hyper-V VSS Writer has failed at prepare snapshot. The error is VSS_E_WRITERERROR_NONRETRYABLE.

Hello sabogj

The error you get (0x80070005) means permission denied, so please make sure the user you are using for the Hyper-V backups have all require permissions granted, these are:

1. Create a Domain User for Hyper-V backups and recoveries.  The account only needs login name and password.
2. The Domain User account must be added to the these Active Directory Users and Computers Builtin security groups:
   1. Backup Operators
   2. Hyper-V Administrator
   3. Windows Authorization Access Group
   4. Users
   5. Remote Desktop Users
3. Also add the Group Policy Creator Owners security group to the Domain User account
4. On each cluster node, log in and perform steps to add the Domain User account to the local node’s
   1. Users group
   2. Administrators group
   3. Hyper-V Administrators group
5. Provide access for cluster management to the Domain User account, using the Grant-ClusterAccess PowerShell command.

Thank you,

Carlos

I followed the steps that Karsten_Bott executed in the post15 (net localgroup command), the user has the permits of the guide. Also checked the components Integrations the VM, please check the attached

persist the messages

EPMVS13-02.CORP.EPM.COM.CO : Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

and

ERROR:Microsoft Hyper-V VSS Writer has failed at prepare snapshot. The error is VSS_E_WRITERERROR_NONRETRYABLE.

@Carlos Rojas

I could say that the messages EPMVS13-02.CORP.EPM.COM.CO : Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)), it was solved. The solution was add the user credentials to Networker Remote Exec Services

But the persist message, ERROR:Microsoft Hyper-V VSS Writer has failed at prepare snapshot. The error is VSS_E_WRITERERROR_NONRETRYABLE.

attached the last version nnm.raw

No need to put Remote User here this will not works.

For a Failover Cluster HyperV Backup Image do this:

create a local user for each node of the Failover Cluster

in my case: emc_backup@FQDN in each node

then grant follow permissions to the user emc_backup:

Run the service as follow:

Now setup the EMC Backup Image Client as follow:

You can flag Data Domain if you need. Depend on your infrastructure:

Now insert the user emc_backup@ FQDN of Failover Cluster then all the nodes.

Depends how many nodes you have put each one here:

emc_backup@FQDN (failover cluster name here)

emc_backup@FQDN (node1)

emc_backup@FQDN (node2)

and so on...!

Start cmd as administrator and run

tasklist | findstr nsr

kill all active processes before you start the back up or you'll get SLAVE JOB Error Message

taskkill -IM nsr* /F

Run the PowerShell scripts from the Failover Active Node shared here somewhere to monitoring the Backup Process while you run the Backup from the EMC Management Console.

Hope this help.
