Renumber ethernet interface on CentOS Linux to eth0

When changing network cards (either physical or virtual) it’s often the case that the new card gets a higher interface number. For example, your old card was identified as ‘eth0′ and the new card gets identified as ‘eth1′. This may cause problems in your scripts (networking scripts, iptables settings, network traffic counters, etc.). But it’s also not as clean as you would want (you’re obsessive about these things, admit it!). Fortunately, we can easily renumber the ethernet interfaces!

Windows Server Backup Step-by-Step Guide for Windows Server 2008

The Windows Server Backup feature provides a basic backup and recovery solution for computers running the Windows Server® 2008 operating system. Windows Server Backup introduces new backup and recovery technology and replaces the previous Windows Backup (Ntbackup.exe) feature that was available with earlier versions of the Windows operating system.

 

What is Windows Server Backup?

 

The Windows Server Backup feature in Windows Server 2008 consists of a Microsoft Management Console (MMC) snap-in and command-line tools that provide a complete solution for your day-to-day backup and recovery needs. You can use four wizards to guide you through running backups and recoveries. You can use Windows Server Backup to back up a full server (all volumes), selected volumes, or the system state. You can recover volumes, folders, files, certain applications, and the system state. And, in case of disasters like hard disk failures, you can perform a system recovery, which will restore your complete system onto the new hard disk, by using a full server backup and the Windows Recovery Environment.

You can use Windows Server Backup to create and manage backups for the local computer or a remote computer. You can also schedule backups to run automatically and you can perform one-time backups to augment the scheduled backups.

Backup Basics in Windows Server 2008 R2

A free tool from Microsoft can make backing up data in Windows Server 2008 R2 efficient and almost hassle-free. Here's how to use it effectively.

Back in the day, Microsoft's free backup tool was the now venerable NTBackup. However, that utility has gone to the great recycle bin in the sky.
Windows Server 2008 offers a new set of backup tools, and I want to show you how easy it is to use them with the new Windows Server 2008 R2. Be aware that the new backup feature can't manage backups created with NTBackup.
