Business continuity Data redundancy Backup and Restoring Windows Server Limitations Full Server Backups/Restores Recovering System State Backing Up and Restoring Files and Folders

Business continuity—the activity performed by an organization to ensure that critical business functions will be available to customers, suppliers, regulators, and other entities as required 24 hours a day to those functions.

Methods used to maintain business continuity may include but is not limited to: o Creating a Disaster Recovery Plan (DRP) o Data backups o Server clustering o Off-site backups o Using Uninterruptable Power Supply (UPS) o Implementing alternative power sources.

 Data redundancy—a property of some disk arrays (most commonly in RAID systems) which provides fault tolerance, so that all or part of the data stored in the array can be recovered in the case of disk failure. o RAID 1—Mirrored disk drives. o RAID 5—Data striping with parity  fault tolerance —the property that enables a system to continue operating properly in the event of the failure of some of its components.

 Windows Server Backup (WSB)—provides a basic backup and recovery solution for computers running the Windows Server 2008 operating system.  WSB is not installed by default. It must be added as a Feature through Server Manager: 1. Click Start->All Programs->Administrative Tools->Click Server Manager. 2. Click on the Features Summary Section, Click Add Features on the right. 3. Expand Windows Server Backup Features and select Windows Server Backup and Command-line Tools. 4. Click Next and then click Install. 5. When it is finished installing, click Close.

Windows Backup is not a new role in 2008R2 Can be used to back up remote computers New improvements over 2008 – Can backup single files and folders 2008 had to back up entire volumes – System state backups and recovers can be performed using WSB in Server Manager – Full functionality via command line and PowerShell – Will automatically delete old backups to make room for current backups

Only supports backing up to internal, external or to optical media (CD/DVD). Tape is no longer supported. Data size limit of 2TB per volume that can be backed up Only backs up volumes that are formatted with NTFS Cannot read backups created with NTBackup.exe

Full server backups are the easiest to perform and one of the best types for recovery Full server backup includes(QUIZ): – All local volumes – Critical volumes – System state You can recover individual files/folders Can perform “bare-metal” recovery

What is system state?

Used when you are more concerned with recovering data than the operating system Good for virtual systems or when the operating system can be restored through imaging – Ghost – Imagex.exe

Can be scheduled or performed manually Command line options— – Wbadmin.exe – Wbadmin.exe START RECOVERY – version:09/30/ :30 –items:d:\common – itemtype:File –backupTarget:E: -recursive

START RECOVERY—tells wbadmin.exe to begin restore operation -version—defines the backup version to use for the restore -items—provides comma-delimited list of items to restore -itemtype—specifies the type of objects in a – items list -backTarget—location of the backup file you want to use for the restore operation
