Disaster Recovery to Azure, what about networking?

Veeam Logoby andre.ri » Wed Aug 02, 2017 12:35 pm

Hi

We create backups of our VMs running on VMware ESX with Veeam Backup and Replication. In addition we have some hardware servers which are backed up with Veeam Endpoint.

Now We would like to have a Disaster Recovery solution. We want to have an easy solution to start one or more machines in case they fail (for whatever reason). We do not want to have a lot of effort with changing IP addresses, firewall rules and network routes when things are failing. I already learned, that this is possible with Veeam DRaaS. If I am not mistaken we can run a network gateway in our network which is tunneling the IP addresses to the service provider. Is the same option available when we want to restore to Azure? Especially the network part? And does anyone have real-life experience with that?

Kind regards
André

You can restore backups taken by Veeam Backup & Replication or our Agent solutions to MS Azure, indeed. There is a dedicated product addressing networking needs.

It's called Veeam PN for MS; might be worth checking.

Thanks.

I think that is exactly what I was looking for. Thank you very much.

Do I need licenses other than the Veeam Backup and Replication one?

Nope, as Veeam PN for MS Azure is provided on free basis.

Hello,

one question about IP translation:

I have restored a server with original IP 192.168.1.1 to Azure.
New IP 10.10.1.1
My clients have IPs which are also in same segment 192.168.1.0/24

Will IP translation work in this scenario? So clients cann access the server with original IP?

Regards

Marc

Hey there Marc.

That's exactly what the IP Translation does:

An IP translation rule is a mapping rule that associates the IP address of the original machine with the IP address of the machine restored in Microsoft Azure. For example, a machine in a local network had an IP address 192.168.0.35, and the restored machine has an IP address 10.12.5.214. You can create an IP translation rule that will map the IP address 192.168.0.35 to the IP address 10.12.5.214. When machines in the local network need to communicate with the machine that had an IP address 192.168.0.35, Veeam PN will look up the IP translation rule record and forward the request to the machine that has the IP address 10.2.5.214 in Microsoft Azure.

It adds the IP to the interface of the Veeam PN Site Gateway which then forwards requests to the recovered VM IP in Azure.

Hello Anthony,

thank you for the information.
This was the information i did not found : "the ip is added to PN gateway interface" :-)

An additional question, maybe you can help me also:

We have multiple (virtual) networks with different VLAN and subnets configured for VMWARE guests.
Is it possible to define multiple NICs for the VLANs and subnets for the VEEAM PN Appliance?
Or is it better to install multiple VEEAM PN appliances on the VMWARE cluster?

Regards

At the moment it's one per subnet but it's a FR that the developers are looking into for future versions.

Hi all - how would this IP Translation work in the event the on-premises location (hosting VMware / Hyper-V) was completely lost forever (fire, flood). I'm thinking we'd either 1) build a new on-premises location and restore the full config - but this impacts on the RTO or 2) Restore all the VMs in the Cloud (Azure / AWS) and create a Site to Site VPN to where the end user clients are....? Thought?

Hi Challengelogic,

How do the end users clients connect today? What is your exact scenario. Assuming that they are in the 'office' you can still use Veeam PN to create the VPN between Azure and on-premises. However, when they are not in the office (because maybe fire/ flood) then we have a different story. Still in that case you can use Veeam PN from a end user client to Azure but it means some config. You will see in the user guide (https://helpcenter.veeam.com/docs/veeam ... tml?ver=10) that you can use PN also for a point-to-site VPN. The configuration as such can be found here: https://helpcenter.veeam.com/docs/veeam ... tml?ver=10

Hope it helps
Mike
