Veeam JeOS high system requirements

Post by kevin.boddy »

Hi,

Is there any reason why the base Veeam JeOS system requirements for CPU and memory are so high?
I thought we were trying to move away from Windows bloat and being able to do more with the same resources.
8x CPUs and 16GB of memory for a Linux OS that doesn't even have any Veeam roles seems a bit high to me or am I reading the user guide wrong?

Thanks
Kevin

Hi, Kevin.

I bet they were simply copied from VSA in anger. You are absolutely right that the machine where Veeam JeOS is deployed needs to be sized according to the backup infrastructure roles it will run (sum of requirement for each role), while JeOS itself does not need much CPU or RAM.

@Dima P. could you please work with technical writers to fix.

Thanks

Hello Kevin,

We will correct system requirements, indeed it should be lower than VSA: 4 CPU cores and 1GB of RAM.

Thank you for the feedback!

Hope you convince QA to go down to 2 CPU cores (same as vanilla Rocky), this should be plenty for a naked OS that does absolutely nothing :D

The OVA asks for 480GB of storage during deployment. Was that also copied from VSA in anger? :-)

Yes, indeed OVA is just a pre-deployed VSA ISO. We just did not have time or resources to create different t-shirt sizes for OVA.

Just in terms of memory usage on proxies. We have been burned by synthetic transformations during the merge phase as these consume a lot of RAM compared to standard active fulls and incrementals so hence we settle of 28GB RAM for each of our proxies with the workload parallelism we run. If there isn't sufficient RAM for the transformations then this may slow down/crash the proxies with out of memory errors and make trouble shooting really hard.

Ok, 2 CPUs and 1GB RAM for a VIA-based machine sounds good to me (even 4 CPUs if it's unavoidable). To be honest all Rocky 64-bit JeOS VIA-based machines I created have 4 CPUs and 4GB RAM so far, just as I created those proxies with Windows Server 2025 based machines. Now, if I take this 2 or 4 CPUs with 1GB RAM configuration as a base for VIA-machines (including hardened repositories), do I need to add the same amount of CPUs and/or RAM for any concurrent backup task (on proxy machines), just as on a Windows based machine?

Hi Didi7,

Yes, the sizing is identical to Windows proxies or repositories sizing in previous versions, just remember you need to add up the compute requirements (CPU and RAM) for each backup infrastructure component that will be deployed on JeOS (for example proxy + repository) and add those on top of Software Appliance system requirements.

Hi Dima P., thanks for clarifying. Maybe I did not mention it clear enough. Proxies here (in this case virtual VMware Proxies) are seperated from Hardened Repositories (which are physical machines here), but I understand that I need to add compute requirements (just as I did in Windows) depending on what additional roles are installed on the appliance on top of the VIA-based system requirements, which are 2 or 4 CPUs and 1GB RAM.
