backup proxy doubts

[davicillo]

good afternoon,

The query is about what mode of transport the proxy uses when we check the Automatic selection option.
On the other hand, can they choose different modes depending on each machine within the same task?
We have seen that if a machine has snapshot the option Direct Storage Access is not supported.


Thanks a lot

Hi David,

Veeam detects proxies which can access the source datastore and automatically assigns an optimal proxy for VM processing. Proxies are assigned one by one and if more than one proxy is available, our business-logic will analyze transport modes that can be used to get VM data and the current load level on every proxy server in order to pick the best one.

Thanks!

And regarding transport modes priority, those are selected (in case several are available) in the following order: Direct storage access > Virtual appliance > Network.

But in the same task can you choose different proxies for each machine of that same task? Or does it choose the proxy for the task and all machines are run with the same proxy?

Thank you both very much

Yes, but in case you have the possibility of the three methods, I understand that you choose the most efficient and not necessarily in that order. We have tasks that for efficiency always choose HotAdd even if we have all three

If by "task" you mean a job, then yes.

Or does it choose the proxy for the task and all machines are run with the same proxy?

Not, it does not.

Thanks!

Sure, proxy selection is done on a per VM basis, i.e. you can potentially have multiple proxies processing the different VMs in the same job.

Likely slots on direct SAN proxy are occupied by other tasks.

Not, it does not.

Thanks!

I am referring to a scheduled job with different machines, if the proxy chooses the best option for each VM or only chooses for the scheduled job in general.

Sorry, I didn't explain myself well. I don't mean the proxy, but the mode of transport within the proxy

[foggy]

The proxy is selected based on available transport modes.
