@Alexey Tesov 

Please follow the below DOC and use the correct Syntax:

https://documentation.commvault.com/11.24/essential/117985_backup_cvvirtualmachine.html

Thank you for your answer, but syntax is not an issue in my case

Hello @Alexey Tesov 

Before running the command, are you able to login to your commcell environment using Connect-CVServer cmdlet? 

Also, is your proxy/access able to connect with vCenter? Are you able to ping, nslookup, telnet (443) from access node to vCenter?

Best,

Rajiv Singal

Dear @Rajiv,

Yes, my mistake -- I had to provide with more context, sorry

All other aspects are fine, I did Connect-CVServer -- no issues, other commands (like Add-CVVirtualMachine / Get-CVVirtualMachine) run perfectly

If I try to start backup by ID (Backup-CVVirtualMachine -Id $vm_id)  I got the error as well

Hello @Alexey Tesov 

What is the string value are you providing while using -Id or -name switch?

Also, while running the command, can you mention -clientname first and then the other switch -name or -Id?

Best,

Rajiv Singal 

Oh Rajiv, I already tried everything possible...

for -Id it is just an int number as a string (“1000”)

I tried direct string] values as parameters, I tried to pull data from CV for parameters:

$VmDetails = Get-CVVirtualMachine -Name $target

$VmName = (Get-CVclient -id $VmDetails.pseudoClient.clientId).get_Item("clientName")
$VCenter = $VmDetails.client.clientName

Backup-CVVirtualMachine -Name $VmName -ClientName $VCenter

I tried to swap parameters:

Backup-CVVirtualMachine -Name <String> -ClientName <String>
Backup-CVVirtualMachine -ClientName <String> -Name <String>

and nothing works for me

Hello @Alexey Tesov 

I understand. I would suggest opening a  case with us further to check on this.

Best,

Rajiv Singal

Yes, I will try to do few more attempts tomorrow (with a fresh mind), maybe I missed something; before case opening..

Thank you

Hi was there a solution found for this? I am also attempting to automate some backup/restore jobs using backup-cvvirtualmachine and restore-cvvirtualmachine however I get the same error message. 

Seems that the command has a problem finding the client. 

PS U:\> Backup-CVVirtualMachine -Name vmname -ClientName clientname
INFO: Get-CVVirtualMachine: no virtual machines found for client lclientname]
INFO: Backup-CVVirtualMachine: virtual machine not found having name vmname]
