at the moment we're testing VEEAM 9.5 Update 3 in our company. Our testlab consists of 1 Backup Server (Windows Server 2012 R2, 4 CPUs, 16 GB RAM) and 1 Proxy/Repository Server (Windows Server 2012 R2, 8 CPUs, 64 GB RAM). All Servers are virtual under vSphere 5.5. By testing we see a problem like it is discussed in this topic. The Backup of our 4 Test-VMs starts fast but the Cache on the Proxy Server fills up over time. When the Cache has filled up the 64 GB RAM the performance slows down extremly. I know that Windows Server 2008 had a problem with this but how i mentioned, we use Windows Server 2012 R2. And yes, after the backup the Cache remains full. Only when we delete the backup it is freed. The job says that the bottleneck is the network. But we know that our SAN (DELL Compellent 8000er Series, 4 GBit FC) can write more than 60 MB/s
.Any idea where to look ?
