Backup Proxy transport mode limit?

[Anders]

Hi

I have a customer that have 4 Veeam proxy servers. 3 of them are VM's on each of their 3 hosts in their VMWare 5.1 cluster. The 4th is the Veeam server itself, and is a physical server setup for direct SAN access.

Each of the 4 proxies Work by them selves, but when a VM with multiple disks are being backed up, some of the disks often failback to Network mode. We've investigate this, and think we have found a logic in it.
When both direct SAN and Hotadd is being used on different disks of a VM being backed up, the hotadd failback to Network.

Is this just a limit, that you cannot use Direct SAN and Hotadd at the same time on the same VM for multi-disk VM's?

Thanks,
Anders

Hi Anders, no such limitations are known. Thanks!

Anders, are you saying that the same disk processing does not fail over to network when direct SAN is not used to process other VM disks?

[Anders]

Yes. When the 3 proxy servers that all use Hot-Add is used, it Works fine. But as soon as the Direct SAN proxy tries to help, the hotadd fails back to Network. Thats what we think anyways.

Maybe we should just open a support case? Is anything writen in logs about why a proxy does failback to Network?

Yes, logs will shed the light on the reason of failover.
