Veeam Backup vs PHDvirtual Backup part 3- Handling disaster recovery
February 22nd, 2011 | 
Author: After a rather successful part 2 of this series, it is high time to kick off part 3, which covers Replication and Disaster Recovery (DR). Most important to note, that backup and DR are two completely different things, and one should not be tempted to combine both unless you are positive your solution will cover all business requirements for both DR and backup.

Veeam Backup vs PHDvirtual Backup part 2- Performing Backup and Restores
In part 1 of this series, I looked at two solutions for making virtual backups: Veeam and PHDvirtual. In this part, I’ll be looking at installing, making backups, verifying backups and of course restoring items.

Veeam Backup vs PHDvirtual Backup part 1- Introduction
For a long time I have been a fan of PHDvirtual (formerly esXpress) and their way of backing up virtual environments. Their lack of ESXi support has driven a lot of people towards other vendors, and the one that is really on technology’s edge nowadays is Veeam’s Backup and Replication. Now that PHDvirtual has released their version 5.1 with ESXi support, it is high time for a shootout between the two.
Some history on drawing virtual backups
In the old ESX 3.0 and ESX 3.5 days, there was hardly any integration with 3rd party backup products. Read the rest of this entry »

esXpress uses vStorage API for detecting changed blocks
Today at VMworld 2009 is joined a breakout session presented by PHD Virtual about their latest version of esXpress (3.6). Great stuff once again! Apart from the fact that esXpress is now fully functional on vSphere (still no ESXi support though), they also managed to use the vStorage API for “changed block reporting”. Basically what this means, is that when you are using vSphere and doing delta or deduped backups, you no longer need to read all the blocks of a VM and then decide is that block was changed or not. PHD managed to get esXpress so far that it reads only the changed blocks directly by using this “cheat sheet” that VMware was so nice to make available though the vStorage API.
What this means is, that backup speeds will be way higher when you do delta or deduped backups.
When you also use their dedup targt, with the dedup action going on on the SOURCE, you get tremendous backup speeds and as an added bonus you can use smaller WAN links when you are sending these backups offsite. Wonderfull guys, you did it again!
