Azure Testing

Hi All
We recently build a B & R VM in azure running on a F2 size instance and standard managed disk 4TB. Over our 100MB fibre link using IPSEC we are getting a 15MBps backup copy transfer speed which is pretty reasonable.
We did a test backup which all went great. We have now completed a test restore to Azure from the VM running in Azure. We restored the VM to premium storage but noticed we are getting pretty average restore rates, Only around 18MBps.
I checked the specs and the standard storage (reading from) should tap out at around 60MBps so wondering why the restore performance is so low. Just wondering if any of you regularly run test restores from an azure B & R server and what sort of throughput you are getting.
If you are getting a much higher throughput, what are the specs of your Azure Instance B & R Server.

More information regarding the restoration procedure. What type of restore was used? Where backup server and backup repository were located, etc.?

Hi, It was a full VM restore to azure from the backup and replication server stored in Azure in the same tenant. I didn't use an azure proxy as the B & R server is located in the same region so figured it wasn't required.

Hi Guys
Just ran another test:
Source Azure B & R Server: F2 instance with Standard Managed Disk
Destination: Same Region, Tenant, Vnet, Premium storage account
Veeam Throughput 32MBps
Source B & Recovery Server Resource utilization

Well i have completed some more testing this morning and still not really getting the restore response i was hoping for in azure. So far this has been the throughput of my tests.

Architecture

On Prem
-Veeam Backup & Replication Server

Azure
-Veeam Backup & Replication Server
-Virutal Network Gateway with IPSEC VPN

Test VM Backup
-180 GB Full Backup on Prem Server
-Backup Copy job to Cloud Server

Restoration Procedure
-Import Backup copy job on cloud server
-Direct restore to Azure in same datacentre


Restoration Speed from Azure B & R Server to Same Subscription and datacentre.
From standard Managed Disk to standard account, 36MBps using F2 Instance as B & R Server
From Standard Managed Disk to Premium Account, 36MBps using F2 Instance as B & R Server
From Premium Managed Disk to Premium Account, 37MBps using F2 Instance as B & R Server
From Premium Managed Disk to Premium Account, 39MBps using DS3_v2 Instance Instance as B & R Server

The final test i need to complete is using a veeam proxy server in azure, however i don't really see the point of this unless the restore is being run from the onprem environment.

Are any of you guys getting similar speeds or better speeds? If so what is your magic formula as i'm stumped

Is anyone actually using azure as a recovery option? With these speeds i don't see that it is a plausible solution? It would be good to get some feedback from the veeam community so we can decide if we should move on and look at other options

Hey Luke.

This is a complex one to respond to with any certainty because millage might vary depending on individual use cases, however the numbers you are putting up are not far off what I have read about and observed in Azure. The Direct Restore to Azure feature is popular and used by a lot of our customers, but you are not going to get super low RTOs compared to say using Cloud Connect Replication from on-premises to a VCSP.

Out of interest what is the specific use case here?

Hi Anthony
thanks for the reply, We were thinking of using it either as Cloud Connect repo or for customers that are big enough to warrant their own B&R server in Azure.

No worries Luke.

So those are both valid use cases, but there is a point in where Azure for Cloud Connect stops being viable. It's best suited to smaller data sets or for VCSPs looking to test the waters before investing in their own infrastructure.

If you have access to the VCSP forum...Have a look at this thread for some more background: post257060.html#p257060

Thanks Anthony, Some of our workloads we are looking at testing are around the 500GB mark and seem would take a fair while to restore if required, especially if requiring restoration of multiple VM's
