Network throttling rules question

Veeam Logoby jochot » Fri Apr 13, 2018 10:09 am

Hey,

so I read through this page: https://helpcenter.veeam.com/docs/backu ... tml?ver=95
I get that more jobs within the same throtting rule then share the throttled bandwith, like explained here:
"Veeam Backup & Replication equally splits available bandwidth between all jobs that use backup infrastructure components to which a network throttling rule applies. For example, if you run one job that uses a pair of backup infrastructure components to which the rule applies, the job will get the entire bandwidth allowed by the rule. If you run two jobs at a time, the allowed bandwidth will be equally split between them. As soon as one of the jobs completes, the bandwidth assigned to it will be freed, and the remaining job will use the entire bandwidth allowed by the rule."

But I have a somewhat different situation:
HQ is connected with a 100mbps line
now I've got two branch offices(BO1 and BO2) from which I want to copy backup data.
I'd like to throttle the network traffic, so I use two rules:
1. from BO1subnet to HQsubnet limit to 80mbps
2. from BO2subnet to HQsubnet limit to 80mbps
Now I have a job copying from BO1 and one copying from BO2.
Does Veeam recognise, that, even tough they don't share the same throttle rule, they should be limited to 40mbps each instead of 80mbps each? (lets say two jobs running from each BO, meaning they should be throttled to 20mbps each).

The above mentioned quote isn't really clear here, as "between all jobs that use backup infrastructure components to which a network throttling rule applies [...] to which the rule applies"
sounds like this applies to ONE rule, but I'm not sure how it behaves when you have more than one rule including one infrastructure component.

Your understanding is correct, this mechanism, applies to a single rule, so in your example each of the two connections will have 80Mbps available for its jobs. However, if you include both source subnets into the rule, the range will be split accordingly.

Ok thanks for the answer!
I've got another question:
Same environment as above.
In HQ i've got the BackupServer.
In BO1 and BO2 I've got some NAS storages and for every BO one Gateway Server/WAN Accelerator.
Now I want to copy the data, is it enough to have the rules applied to the IP's of the Gateway Servers or do the NAS have to be included?
As the Gateway Server is in a different Subnet as the Storages.

So:
BackupServer HQ (192.168.0.70)
GatewayServer BO1 (192.168.10.70)
- NAS01 (192.168.11.1)
- NAS02 (192.168.11.2)
-etc.
GatewayServer BO2 (192.168.20.70)
- NAS01 (192.168.21.1)
- NAS02 (192.168.21.2)

Rules should be:
192.168.10.70 -> 192.168.0.70
192.168.20.70 -> 192.168.0.70
or does it need to be
192.168.10.0 - 192.168.11.255 -> 192.168.0.70
192.168.20.0 - 192.168.21.255 -> 192.168.0.70
?

Gateway servers' addresses are enough, so these rules should work:
