Hi Mike,

i work for a NetApp integrator and use Ontap (FAS/AFF etc) or eSeries often.

Normally the Ontap System is always the Source. As Veeam Repository the FAS ist normaly to expensive. I recommend a eSeries with a linux server as hardened repository, in best case direct attached FC or SAS, not iSCSI.

In any case if Ontap MUST be your repository, use block storage (fc or iSCSI), no NAS Storage.

How does your setup look like?

Thanks for the information. That is very useful to know but I also need good de duplication ratios as well. What have you seen with FAS and also immutability

As you said - eSeries does no Dedup, just that efficiency what veeam does.
Ontap has the option to do dedup. My experience with this is bad whan you have only a low count of hdds, because backup change raates are normaly high.

I have two values for you, customer, onprem iscsi LUNs with ontap, 30 tb used, dedup does ~6% savings on top to the veeam savings.

In another environment i have a bigger setup with over 27% dedup savings.

But again i recommend a eSeries, not a FAS System.

Hi. So you saw 27% saving with veeam settings on eseries? 

no both values are from FAS Systems. Veeam Dedup does not depend on the storage? Choose any block storage for veeam, it is software dedup+compression - so it depends on your source data.

Yes understand that it's down to veeam but I don't think we'll get any more than 5:1 when we just have eseries

no if you want to have such dedup ratios you need a dedup appliance like Exagrid.

With veeam efficiency you get dedup and compression savings. But with per VM chains dedup is only per VM backup chain. Often compression get’s you more savings than dedup.

Best is to calculate with 2:1 based on your source data (RVTools used data on VM).

thanks for that. We might need to consider ExaGRID etc but need to keep costs down

Hi @MavMikeVBR - just wanted to follow up on this post to make sure you got an answer so we can mark off a best answer.  Just let us know.
