VBO OnPrem connect to Load Balancer

[Daniel Bung]

Hello together,

We have an On Prem SharePoint Environment, which we want to backup with Veeam Backup for Microsoft 365.
For testing we add one of our SharePoint Servers to Veeam and this runs fine.
But now VBO must access the Central Administration via Win Rm Port 5985/5986, to ensure redundancy the access should be done via the load balancer.
Currently in our Scenario not possible because only ports 80 and 443 are distributed via the load balancer.
ð The following information is required to set up Win Rm ports 5985/5986:
o How many connections are established to each end system. (currently max. 65,000 per end system possible).
o How high is the maximum data throughput?
o What is Veeam's best practice here?
o Is it necessary to build another LoadBalancer instance in production so that the traffic does not affect the users?

Thank you for your Help .

Hello,
and welcome to the forums.

As most people back up on-prem sharepoint farms VM-based or agent-based, I cannot remember any best practices around load balancers.

Maximum throughput in general is hard to predict. It depends on the hardware, number (size) of the objects etc.

As the user guide says that WinRM is required... did you see it working without?

With the information given, I'm not sure how an additional load balancer would help... so I would go without and see how it goes.

Best regards,
Hannes

Hello Hannes,

Can you say something about the maximum Number of connections which will be established?
i just need a rough estimate.
The Question about the throughput, is meant like, is there a limitation like it is when you Backup SharePoint in the Cloud?

Thank you for your help.

Hello,
throttling as in the cloud version does not exist on-prem. So that limitation does not exist on-prem.

I never heard of any issues with number of maximum connections. If you think that is something you might hit (what kind of environment do you have? ), then I would start with a lower thread number in the proxy settings

Bes regards,
Hannes

Hi Daniel,

The amount of connections is going to be difficult to say, even roughly. It depends on how much data you are going to protect which could mean 10000s or more of connections that is going to happen over the time of the backup.

I don't understand the loadbalancer. I assume you have something like "sharepoint.companyname.internal" and that is the loadbalancer distributing the load over a farm of sharepoint servers? I think for backup it might be more interesting to point it directly to one specific sharepoint server

And about the throttling. Throttling mechanisms do exist in SharePoint Online but those settings are in the central administration and by default those settings should be good enough for backup
