To use a Backup Proxy or not in Veeam Backup & Replication

We just purchased Veeeam Backup & Replication and I'd like to understand if a proxy is recommended as I read it is, but want to see what others using Veeam are doing for verification.  We have a virtual infrastructure at corporate and are not doing any offsite replication.  The backup server is the default proxy, and we have about 20 VM's we're backing up.  Would we be best to have a proxy and if so can it be on any of my other VM's or is it resource intense and should be on it's own machine or a non-VM machine.

you need at least 2 vCPUs for a Veeam Server or Proxy Backup Server.

Direct-SAN mode, will improve performance, you only have 20 VMs which is not many. Try Direct-SAN mode.

We implement only Virtual Servers (other than vSphere hosts)

Backup Proxy can be installed on any Windows Server, we use dedicated servers and Add the Proxy roles to move data from VMs to backup.

Its always recommended to have Proxies at Production and DR sites for replication.

Configure Direct SAN access for increased throughput

We have about 60 server VM's in our environment. My boss has been experimenting with VEEAM. Although it has worked, it's always been a struggle.  What he finally did was to create four proxy servers controlled by a master server to do the heavy lifting of the backups and that seems to have really done the trick.

I've also heard from someone that in his environment the VEEAAM process improved when they moved it off of a VM onto a physical server with ton's of RAM and 12 cores of CPU.

@hanccocka - are your dedicated servers independent of your virtual environment?
Currently we do not have replication so I would only be using it to offset the server resources. The link recommends DAS, but our DAS is the storage I want to backup (all my VMS are on the DAS EMC SAN) thus I thought it should be on something outside of what I was trying to backup though my backup server is a VM.  Thoughts?

@jhyiesla - so the master is your backup server and are the proxy servers VMs or stand alone servers and are there other apps on them or strictly proxy use alone?

All - It sounds like a server outside of my VM would be advised, but do I need to run a server only for the proxy or can I use an existing file server or another robust applicaiton server?  Recommendations?

ok so your proxies are VM machines?
are they on the same storage you have the data you want to backup on?
I'm anticipating sprawl since VM is new to us so want to make sure planning properly.
is your Proxy server dedicated to only Veeam as a proxy and no other applications?

we have a few other lightweight services that run on the VM, which are virtual specific, eg VMware Converter, VMware Tools, vCLI, Powershell, scripts, RVtools,, vSphere client, SQL Management Studio, Alerting, Reporting, Splunk Syslog

its easier for folk to RDP and do some admin, and only one computer to make sure updated

Yes all VMs on the same iSCSI storage.

Can I ask what you have that machine configured for CPU and memory?

The jobs are created and managed on the master server. It then hands off the actual backup tasks to the proxy servers. All of the Veeam servers in our environment are VMs.

Thank you for the excellent detail I will configure a server for proxy and it appears for load balancing should have more than one so excellent advice
