Veeam Backup for Windows Performance.

Hi,

The requirements are quite generic and you need to review your individual bottlenecks to increase throughput.

The common bottlenecks are network & disk. Depending on whether you’re backing up a single endpoint with a 1Gbps NIC (or worse, Wifi) and a single SATA spinning disk, or a decent spec’d server with 10Gbps NICs and a performant RAID controller, are going to be very noticeable differences.

I’d start here. What are you backing up to? Is it based over the network, or is it a locally attached disk such as a USB 3 hard drive?

And what are you backing up from? A low-end disk or something performant?

Once you’ve got the utilisation of these devices, that’s where I’d look to see if they’re under performing. If you’re getting 100MB+ on a 1Gbps NIC, you won’t increase throughput without increasing the bandwidth for example.

Assuming that your disks & networking are being under utilised, I’d look at RAM next to ensure that nothing is being throttled by disk paging due to memory pressure, afterwards I’d look at CPU, if your CPU is the bottleneck, it could be genuine workload CPU demands, or it could be excessive compression, high & extreme compression tasks can saturate a weaker CPU fairly easily. Especially when you can feed the data to the CPU quickly with flash storage.

Hope this helps, if you’ve got further questions just ask 🙂

for me the basics are

• vm or server resources (specially Veeam Server and proxies)
• network speed / quality (enough bandwidth and speed)
• source and destination disks speed (from ssd to mechanical, don't expect ssd speed for example)
• then, many things, like @JMeixner and @MicoolPaul said.
• it depends…..
  
  cheers.

I like to have, bare minimum, 32GB RAM and 8 cores in my backup servers. 64GB and 16 cores is even better!
