Ok I read an article from one of our competitors that basically slated inline dedupe, saying it was not worth having over speed of backup. I feel they only said this coz in terms of their development cycle it would be years before they could introduce dedupe in their own technology. Now I knew what they were saying wasn’t the case as I’d seen fist hand how efficient our Backup solution could be with dedupe turned on, and the time penalty was low. So I set about researching the possibilities.
I did some extensive testing and with a little help from @MikeBeevor we created a whitepaper from my findings.
Below is graph demonstrating the effects of just compression, just dedupe and what happens when both are turned on.

As you can see you get massive disk savings with our technology. For example if allocated VM disk space equated to 100Gb then Veeam Backup could potentially only need about 17GB. A saving of 83% on allocated disk space.
I don’t want to give the game away too much so if you want to read on download the whitepaper from here > http://www.veeam.com/whitepapers.html

I wanted to reduce the heat generated by my home lab as its in the Loft/Office and wanted to automate any procedure. Decided to enable DPM for the very first time and the task I faced was controlling when DPM was enabled or disabled. If you’re not familiar with DPM its VMware’s vSphere technology that automates ESX hosts placed into standby power mode when overall utilisation is low. My home lab is used for demo and in working hours I didn’t want to have to wait for DPM to power on a standby host mid-demo. So I needed a way of controlling DPM off/on peak. At first I was going to create an API app similar to My Resource Pool Scheduler but then decided this would make a great PowerCLI lesson. I went about finding out how to control DPM using PowerCLI as described >here<. I then used the windows scheduler to activate a DPM-ON script and a DPM-OFF script. It was as simple as that. So 7am DPM is switched off and all standby hosts are powered on. 7pm DPM is switched on allowing for hosts to be placed into standby mode.
