Are your Veeam Backups failing because your VMs live in DMZs or tightly firewalled networks? You're not alone! 

In large-scale, secure environments, traditional network-based Guest Processing often hits a wall (literally!). But there's a simple, yet powerful, fix you might not know about: Changing the order of Veeam's Guest Processing Methods.

We're diving deep into the Why and How of prioritizing networkless processing for both VMware vSphere and Microsoft Hyper-V. This quick configuration change ensures Veeam always tries the most suitable, hypervisor-channel-based communication first, bypassing those tricky network barriers and keeping your backups successful.

Another great registry key for November.  This one I found interesting.

This is pretty great, I like how simple that regkey makes it to reverse the processing methodology. Definitely something we’ll look into implementing as a service provider.

Nice, honestly I’ve been looking around for something like this since more than a year now. I always get a lot of warnings with the default processing order since I always focus on a specific way for processing (that isn’t always the first one).

 

Thanks a lot!

This is by far one of the best registry keys in VBR I’ve ever heard of. Thanks for this! 

Please nominate for the blog of the month 😊

Thanks a lot!

Glad to hear this helps, With the ‘original’ order you waste a lot of time and end up with warnings which pollutes your logs and monitoring.
