Performance Gain for using remote backup proxy?

[bunger]

In addition to my "local" ESXi 5 boxes ( including a vCenter/Veeam VM ), I have another ESX box on the other side of the state. The box has a single VM that I need to back up to storage locally.

Is there any performance gain to have a backup proxy also located on that same remote ESX box or is it a "wash" to just using my locally-located backup proxy?

Where are you backing up that single remote VM to?

[bunger]

It would be a Replica job to an ESXi 5 host in the local datacenter....

In that case, with the proxy present in the remote site, the job will work up to 5-10x faster, and use about 3-5x less network traffic comparing to "pull" replication with the proxy located in the main site. But, since you only have a single VM to replicate daily, you may not actually need all this goodness.

What about the other way around -- replicating to a DR site across the WAN? Will the replication be faster with a remote proxy installed at the remote DR site?

[Gostev]

Absolutely, the same is true for the opposite direction. You can only get all the v6 WAN coolness if you have backup proxies on the both sides. Without this, things like traffic compression, traffic deduplication and multiple TCP/IP threads are simply not possible.
