Veeam+Exagrid Optimization

[intekular]

Hi,

I currently use Veeam with Exagrid for my backup repositories. I have had it in place and running for several months and I am very happy with how well both technologies are working and the speed they currently run at, but would like to see if there is anything more I can do to optimize the setup.

I have followed best practices from both vendors.

1)I am currently using two proxies each with 4vCPU and 4g or memory.
2)The Exagrid share is represented as two backup repositories with the jobs split between the two.
3)I am using dedupe friendly compression.
4)All networking is 1g.

The repositories are setup to process a single IO stream at this time. Should I bump this up?
The proxies look like each of them can only service a single job at a time while the other jobs queue up. With the vCPU count they should be able process more I thought?

Prompt me for more information and I can fill in more details.

Thanks,

Let's start from the bottleneck stats for your jobs. Could you provide the numbers, please?

Here are the stats for one of my larger jobs containing 17 VM's-

10/13/2014 9:09:23 PM :: Load: Source 89% > Proxy 22% > Network 25% > Target 36%

Looks like if you want to optimize backup performance, you should pay your attention at the source data retrieval speed. What transport mode is being currently utilized?

If you use Parallel processing your Exagrid repositories have to be set to 1 stream. You can create more jobs with a smaller amount of VMx and have them all run at the same time to each repository. I use Exagrid appliances and if I could go 10G, I would. Also, be aware that Exagrid has software coming out soon that lets the appliances themselves act as data movers and decreases the processing time of synthetic fulls.

Foggy-I am using Hot-add. I will review the link.

Daveyd-There is 10g budgeted for next year, so hopefully all of the backup infrastructure and core networking will be running at that speed.

What kind of source storage do you have? If there's an ability to utilize direct SAN backup mode, I would try it.
