.SYNOPSIS
|
|
Backup the BitLocker Recovery Information to the Azure Active Directory
|
|
|
|
.DESCRIPTION
|
|
Backup the BitLocker Recovery Information to the Azure Active Directory
|
|
If the Boot Drive is not encrypted, the Script will try to enable the quick protection
|
|
|
|
.EXAMPLE
|
|
PS C:\> .\Invoke-BackupBitlockerRecoveryKey.ps1
|
|
|
|
.EXAMPLE
|
|
PS C:\> $AADInfo = (Get-DsRegStatusInfo | Select-Object -Property AzureAdJoined,WorkplaceJoined)
|
|
PS C:\> if ( ($AADInfo.AzureAdJoined -ne 'YES') -and ($AADInfo.WorkplaceJoined -ne 'YES') ) {throw 'Not AzureAD bound'} else {.\Invoke-BackupBitlockerRecoveryKey.ps1}
|
|
|
|
You may want to check if the device is AzureAD joined with Get-DsRegStatusInfo first
|
|
|
|
.NOTES
|
|
Quick and relative dirty solution for a challenge I had in the last couple of days
