Network traffic rules and offload via gateway

[desmith]

For network segregation reasons we have 2 BNR servers at a particular site, sharing a WAN link.

Originally I had both configured to offload directly to S3 storage, with network traffic rules throttling internet traffic to 60% of WAN capacity, but more frequently than expected, both servers would be offloading at the same time and degrade WAN performance.

I assumed if I made one server use the other as a gateway for capacity tier, if offload jobs did run concurrently, the internet throttling rate would apply to combined egress traffic from the server, but we had 2 offloads run over the weekend and the link was maxxed out. The server that makes use of the gateway started uploading first, using about 70% of our bandwidth (I'm unsure if any throttling was applied), then the server acting as gateway also started uploading using all of the remaining 30%.

Has anyone else tried similar configuration?

Hello,
each backup server is working independent. It does it's own bandwidth calculation etc. and does not care whatever the other backup server has configured. The gateway is a "dumb" data mover with no intelligence.

If both upload at the same time and you like to end up with around 60%, then each VBR server needs to have 30% configured.

Best regards,
