Backing up and Recovering Virtual Machines
4959_Ch07_CMP3 4/20/05 5:30 PM Page 223 CHAPTER 7 ■ ■ ■ Backing Up and Recovering Virtual Machines For virtual machines running in a production environment, backup and recovery is just as serious as for all the other servers on the network. When running servers inside VMs, you’ll be faced with several new challenges, as well as advantages, when planning and implementing a backup strategy. In this chapter, you’ll explore the process of planning for and administering backup and recovery operations on VMs and VM hosts. Along the way, you’ll see the different approaches you can take to secure VM data, which include the following: •Traditional agent-based backups •Non-agent-based backups •Flat-file backups Also, many organizations have embraced the idea of maintaining a warm standby VM server that can be brought online if a primary server fails. This approach, for many organiza- tions, may mean that data is unavailable for a few minutes following the loss of a server. If you can’t afford to cluster all your systems, or if some of your applications don’t support clustering, then you may find this approach to be a perfect fit. Since the focus of this chapter is purely on VM backup and recovery, we’ll walk you through the process of maintaining a standby VM server in Chapter 14. Optimizing your backup strategy often means much more than simply installing software and letting it do its magic. Oftentimes, custom scripting is required to get the backup results you desire. Because of the importance of getting your virtual infrastructure to work around your needs (instead of the other way around), we’ll also show you several scripting ideas to both enhance and automate the backup, recovery, and availability of your VMs. -

Dell Feature and Functional Testing for Windows Server 2008
Dell Feature and Functional Testing for Windows Server 2008 By Barun Chaudhary and Manjunath Narayanan April 2008 Windows Server® 2008 is Microsoft’s first major Server Operating System release in five years. Dell’s close partnership with Microsoft has allowed engagement with the testing and development of this operating system for more than 4 years. Some of the highlights of Dell’s testing efforts include compatibility tests on Dell™ PowerEdge™ server platforms, testing upgrade and migration scenarios, and testing compatibility of OpenManage™, the Dell systems management software. Whenever there were new features or technology included with the Milestone or Beta releases, Dell endeavored to ensure that as many of our platforms and OpenManage components were ready to support those features as possible. Based on the current status of testing, Dell is committed to supporting more than 40 currently shipping and legacy server platforms across 5 generations with Windows Server 2008. Supporting this number of servers has required significant development efforts to help ensure good customer experience. Dell has a set of internal tools to track various parameters like test results, defect tracking, total time spent, driver or firmware changes, etc. Dell estimates it has spent more than 1800 hours testing currently shipping and future Dell servers for compatibility with Windows Server 2008. An additional 1700+ hours were spent at Dell to help ensure OpenManage will be compatible with Windows Server 2008 on as many platforms as possible. To serve this purpose more than 30 different configurations were tested on different Dell platforms. In addition to these efforts, Dell has spent more than 750 hours testing various Windows Server 2008 features on the entire supported server line.
