Hi everyone.
In a Veeam backup for REV implementation, what is the maximum recommended resources for the Proxy that is deployed within the REV environment, this is because only 1 proxy can be deployed per REV cluster.
additional as would be the sizing of this, since the default configuration of the proxy is 8 CPU Cores and 4 GB of RAM for 4 concurrent jobs, what is the formula to add more resources?
thank you.

Re: How to sizing REV Proxy Server
Hello,
and welcome to the forums.
As of today, the user guide says 1 CPU & 1 GB RAM per task. One task is one VM. That means with 4 tasks (default settings), 4 VMs are backed up in parallel. Depending on your RPO time, amount of data and change rate, that might be enough for 50-100 VMs.
How many VMs, data, change rate and RPO time to you have?
In general, the formulas are the same as for VMware. The main question is, whether you need active full backups or not. If you are fine with forward forever incremental backup mode, then one only needs to size for that instead of active fulls. If you use inline deduplication appliances as backup target (not recommended in general), then active full would be required, because there is no synthetic full today.
Best regards,
Hannes

Re: How to sizing REV Proxy Server
Hello HannesK, sorry for the delay, the number of VMs is 380, the size of the VMs is variable between 150 GB and 3 TB and the change rate is 10%, the RPO is 24 hours, it is intended to configure the jobs with FFI at 7 points, if this line is that you have to follow from 50 to 100 VMs I want to think that they would be simultaneous at most.
Just as a doubt if there were more than 100 how would the sizing be?

Re: How to sizing REV Proxy Server
Hello,
I would start with 20 vCPUs (assuming that the physical CPU has at least 20 cores. If not, it might be faster to reduce to physical cores number. I don't know how RHEV does scheduling, but I guess it's not as advanced as VMware) and 20 tasks for the initial full backups. Once the full backups are done more or less, I would increase tasks to 30-40. I know, that's against the user guide, but it works fine for VMware and so I see no reason, why it should not work for RHEV. The user guide thinks about "active full" and is more conservative.
48 GB RAM sound good for 40 tasks to me.
Best regards,
Hannes
