Restore issues following successful backup

[Antoine_D]

Good Day,

Today I am posting again, as I encountered a new problem while trying to restore a single file from a backup disk.

This file was backed-up from an ESXi server successfuly.
The ESXi server name was added in :

Host Properties/Master Server/Properties/VMWare Access Hosts/Add

And also in:

Media and Device Management/Credentials/Virtual Machine Servers

As the full backup ran successfuly, I assume there is no issues with the authentication between the Master server and the ESXi server.

Here are the backup logs :

The logs cleary say "no connection could be established as the target server rejected it"

Is there anything I forgot to configure on my Policy ?

Many thanks & regards

So you can backup but not restore?  Is this correct.

You have you VM servers setup in the credentials, and on the master server host properties? 

[Marianne]

Cannot connect to esx01.xxxxx.yyyy 

Where are you trying to restore to? Looking at above error, it seems as if you are trying to restore to the ESX server?

You can only restore to a host where NBU software is installed - either a VM with NBU Client software installed or to the backup host (probably the master/media server?). Copy file from there to the VM client.

Exactly what Marianne said, cannot restore a file-level backup without a client on the OS.

[Antoine_D]

Good day & thanks for your reply!

@ Marianne : Yes Indeed, I made a mistake in the Restore settings, as you noticed. I have amended these in the meantime : replaced the esx server name by the target VM hostname. FYI, the NBU Agent was NOT installed on this VM...

@DG-2005: "cannot restore a file-level backup without a client on the OS."  yes indeed ^^

Having said that, I ask this question to both of you : how do you do if you install NBU7.5 in an existing environment that contains 10.000+ VMs (CentOS & Windows) and you want to deploy this client agent on each of them? Can you advise any deployment tool by any chance, please?

Many thanks!

[Marianne]

Do you really need NBU Client software in 10000+ VMs? 

Full VM restore does not need NBU client installation, only single file.

For the odd single file restore every now and then, you may as well restore to the backup host (which is probably the master or a media server) and then copy the file to the relevant VM.

Install NBU client in one or two Linux VMs that you can use for CentOS file-level restores.

[Antoine_D]

Marianne,

No I dont actually need to deploy the NBU Agent on 10.000+ VMs today, but I will soon be asked to deal with hundreds of them -- and what I dont want to do is to install an agent manually on each VM individually.

>> "For the odd single file restore every now and then, you may as well restore to the backup host (which is probably the master or a media server) and then copy the file to the relevant VM."

I will certainly suggest the idea !

Many thanks & regards,
