Here’s a basic Windows PowerShell script configure Windows Server 2008 R2 Backup.

# -----------------------------------------------------------------
# Script to set a Windows Server Backup policy for a server
#
# Assumes: Volumes C: and D: to backup.
#        : Target - \\storageserver\serverbackup
#        : Exclusions - D:\temp, D:\Users\*.MP3, D:\Users\*.WMA
#        : VSS Mode - Full Backup
#        : System State - True
#        : Bare Metal Recovery - True
#        : Schedule - 12:30 PM, 11:00 PM
# Requires: Elevated PowerShell
#         :   (Must be run As Administrator)
#
# Planned Improvements: [minor] Check for elevated priv, error politely if not
#                     : [minor] Check for Server Backup PSSnapin before trying to load
#                     : [major] Accept cmdline parameters

# By default, the PSSnapin isn't loaded automatically, so first load it.
Add-PSSnapin Windows.ServerBackup # will error if already loaded, but continue
# First, create a new empty policy
# Alternately, you can open the existing policy in Edit mode with
#   $BackupPolicy = Get-WBPolicy -edit
$BackupPolicy = New-WBPolicy
# Now, define the parts of it.
# First, let's do the "source" volumes that will be part of the backup.
# This requires us to first get a list of them, and then parse that list
# to add the ones we want (C: and D:)
# We don't actually need C:, since we'll get that as part of Bare Metal Restore,
# but we include it anyway for completeness
$volC = Get-WBVolume -AllVolumes | Where {$_.MountPath -eq "C:"}
$volD = Get-WBVolume -AllVolumes | Where {$_.MountPath -eq "D:"}
$Volumes = $volC,$volD
# Now, add those volumes to the blank policy.
Add-WBVolume -policy $BackupPolicy -volume $Volumes
# If you want to do the entire volume, you don't need to define any exclusions,
# but if you want to exclude any files or folders, you need to define that exclusion
# and add that to the backup policy you're building. First, define it.?
$excTEMP = New-WBFileSpec -Filespec D:\Temp -exclude
$excWMA = New-WBFileSpec -Filespec "D:\Users\*.wma" -exclude  # Recursive unless
$excMP3 = New-WBFileSpec -Filespec "D:\Users\*.mp3" -exclude  # -NonRecursive specified
$FileExclusions = $excTEMP,$excWMA,$excMP3
# and then add that to the policy we're building
Add-WBFileSpec -policy $BackupPolicy -filespec $FileExclusions
# Define the backup target, this time as a network share.
# For backup to share, you need to create a credential to connect to the remote share.
# This wouldn't be required for specifying a removable disk.
# You can specify the username here (DOMAIN\User) but will be prompted for password
$Cred = Get-Credential example\user
# Now, define the target
$Target = New-WBBackupTarget -NetworkPath \\StorageServer\ServerBackup -Credential $Cred
# Add the target to the policy
Add-WBBackupTarget -policy $BackupPolicy -target $Target
# Define the schedule
$sch1 = [datetime]"01/31/2011 12:30:00"
$sch2 = [datetime]"01/31/2011 21:00:00"
Set-WBSchedule -policy $BackupPolicy -schedule $sch1,$sch2
# Set for system state and for bare metal recovery
Add-WBSystemState -policy $BackupPolicy
Add-WBBareMetalRecovery -policy $BackupPolicy
# Finally, set for full VSS Backup
Set-WBVssBackupOptions -policy $BackupPolicy -VssFullBackup
# Finally, we need to SET the policy before it actually takes control
Set-WBPolicy -force -policy $BackupPolicy
# This completes the configuration of the SBS server backup policy
$Server = (hostname).tolower()
