Windows 2008 Hyper-V and Windows 2008 Backup

Windows 2008 (or R2) comes with Wondows backup application. It uses Microsoft volume snapshot technology to snapshot volume and copy the configuration and Data in *.vhd format, that is used for Microsoft Hyper-V server, to local attached storage or network storage. For quick data volume recovery, you just mount the *.vhd file to any Hyper-V server and you are done. You don't need any restore time you may need for the traditional tape backup to speed up SLA. If you need to recover systems, you will have to install Windows via CD or image and choose system recovery option during setup and specify where is system volume backup file is located, local media, UNC path, etc. since Microsoft doesn't support to make backup image *.vhd bootable.

 

You use wbadmin command to schedule backup job and restore.

 

You can run Wbadmin by following these steps:
1. Click Start, click All Programs, and then click Accessories to open the Accessories menu.
2. Start an elevated command prompt by right-clicking Command Prompt and then selecting Run As Administrator.
3. In the Command Prompt window, enter the necessary command text or run a script that invokes Wbadmin.

Wbadmin has a number of associated commands:
DELETE SYSTEMSTATEBACKUP Deletes the system state backup or backups from a specified location.
DISABLE BACKUP Disables scheduled daily backups so that they no longer run.
ENABLE BACKUP Enables or modifies a scheduled daily backup.
GET DISKS Lists the disks that are currently online for the local computer. Disks are listed by manufacturer name, type, disk number, GUID, total space, used space, and associated volumes. GET ITEMS Lists items contained in a specified backup.
GET STATUS Reports the status of the currently running backup or recovery job.
GET VERSIONS List details about the available backups stored in a specific location, including the backup time and backup destination.
START BACKUP Starts a one-time backup using the specified parameters. If no parameters are passed and scheduled backups are enabled, the backup uses the settings for scheduled backups.
START RECOVERY Initiates a recovery of volumes, applications, or files using the specified parameters.
START SYSTEMSTATEBACKUP Starts a system state backup using the options specified.
START SYSTEMSTATERECOVERY Starts a system state recovery using the specified parameters.
STOP JOB Stops the currently running backup or recovery job. Stopped jobs cannot be restarted from where they were stopped.

When you are working with Wbadmin, you can get help on available commands:
1.To view a list of management commands, type wbadmin /? at the command prompt.
2.To view the syntax for a specific management command, type wbadmin Command /?, where Command is the name of the management command you want to examine, such as wbadmin stop job /?.

When you work with Wbadmin, you'll find that just about every command accepts parameters and specific parameter values that qualify what you want to work with. To see more clearly how this works, consider the following syntax example:

wbadmin get versions [-backupTarget:{VolumeName | NetworkSharePath}] [-machine:BackupMachineName] 

The brackets tell you that –backupTarget and –machine are optional. Thus, you could type the following to get information on recoverable backups on the local computer:

wbadmin get versions 

You could type the following to get information on recoverable backups for C:

wbadmin get versions -backuptarget:f: 

Or you could type the following to get information on recoverable backups for C on Server88:

wbadmin get versions -backuptarget:f: -machine:server88 

Many Wbadmin commands use the –backupTarget and –machine parameters. The backup target is the storage location you want to work with, and can be expressed as a local volume name (such as F:) or as a network share path, such as \\FileServer32\backups\Server85. The –machine parameter identifies the computer you want to work with for backup or recovery operations.
