Increase the performance of your Veeam backups in network mode

Posted on June 28, 2016December 4, 2016 by Luca Dell'Oca 1 Comment

If you ever tried to do any file operation via the management interface of an ESXi host, like uploading an ISO file or running a backup using Network Mode, you may know the management interface is not running at the full speed of the underlying network interface, and the bandwidth you end up using is only a percentage of the total available. This limit is designed to preserve the availability of the management interface, but still there are situations where this limit is a problem, and you would like to increase it. Hopefully, there’s a solution.

One year ago, i published a series of 10 blog posts called My adventures with Ceph Storage. As I had recently to rebuild my Ceph cluster from scratch, I decided it was time to create a quick guide to build the cluster as fast as possible.

Am I doing backups of all my VMs? 2016 Edition

In 2012 I published a post with a Powershell script to be able to check all the available VM’s in a given vSphere environment, and verify which ones were protected by Veeam Backup & Replication. Time to update the script to make it work with the latest versions of the two software.

The best part of the new Veeam Standalone Console is the fact that Veeam PowerShell snap-in installs as part of this component, and it includes a new cmd-let: Connect-VBRServer. YES! No more PowerShell remoting to invoke your Veeam PowerShell scripts.

Make your own followers rankings with twitter API

I’ve created a quick script a few months ago that reads and sorts the number of followers of different twitter users. A funny way to learn a bit how to use OAuth and Twitter API.
