Networkcards and restore

[b.vanhaastrecht]

Hi,

We've noticed when restoring to Azure from Snapshot or Backup the VM is not attached to it's original network card. The restore creates new one's. Is there a reason for this, we would expect it to re-attach them to the existing ones, if exist. Or recreate them with the settings.

Regards,
Bastiaan

Hi Bastiaan, to be 100% sure, you are talking about restore to the original location in this case?

Hi Niels, yes restore to original location.

Can you answer a few additional questions which will help in clearing out the behavior?

1. Is the original VM still in the production infrastructure or already deleted when you perform the restore?
2. Which settings are not exactly restored? Are we talking about specific IP settings or other ones as well?

[b.vanhaastrecht]

1. No, the VM is deleted, disks are deleted, networkcard + attached NSG + attached public IP still exists.
2. It's not a setting but a new network card object is created in azure attached to the restored VM. Which offcouse does not have the prior attached NSG and public IP attached.

Even if we remove the NIC + NSG + PIP prior to restore, the VM will have a new NIC with dynamic IP which is frequently not the previous IP the VM had. The NSG and PIP is never restored.

The goal is here to restore the VM with all it's dependencies like NIC, NSG and PIP.

Thanks for the info. I'm verifying a few things and will report back asap.

Hi Bastiaan,

On point 1, this is unexpected behavior as we should re-use them if they are available. Could you maybe open a support case for insight via logs?
