Avoid the big mistakes when backing up virtual servers
This article is part of the Virtual Data Center issue of February 2010, Vol. 19
Migrating your servers to virtual machines comes with many obvious benefits; hardware consolidation, performance management, and easier disaster recovery being a few. Some of the drawbacks, however, come from your old infrastructure. The backup systems in particular can come under disruptive fire because most have been designed to support a certain number of physical servers. Now that your server count can grow exponentially, and the assumptions of resource use go out the window, you need to address your backup solution before virtualization causes backups to get out of control. Take the opportunity to build backup planning into new virtualization projects so you can intelligently review your current approach with those that are available. Big Mistake #1: Let it ride and do nothing Agent-based backup is a common method for backing up servers. This involves installing the backup agent on your servers and pushing settings to it from your backup server. You can then backup those servers with nearly the same settings -- save for ...

The abstraction of virtualization makes resource provisioning tricky. Without proper capacity planning, over-allocation can affect performance and waste resources.
The benefits of Windows server virtualization can quickly turn to nightmares if you choose the wrong backup strategy. Learn to avoid the most common missteps.
Application performance is even more important in physical servers that share multiple VMs, so ongoing monitoring and optimization of virtual host servers should be routine in any virtual data center
