The powershell is used to automate the backup of AAS instance. The instance have Multi-factor authentication and I think that is the problem.
Powershell:
$TenantId = "TenentID"
$Cred = Get-AutomationPSCredential -Name 'SSASModelBackup'
$Server = "ServerName"
$RolloutEnvironment = "location.asazure.windows.net"
$ResourceGroup = "ReourceGroupName"
#Create Credentials to convertToSecureString
$applicationId = "applicationId "
$securePassword = "securePassword " | ConvertTo-SecureString -AsPlainText -Force $Credential = New-Object
-TypeName System.Management.Automation.PSCredential -ArgumentList $applicationId, $securePassword
#Define the list of AAS databases
$asDBs = @('database1','database2')
Write-Output "Logging in to Azure..."
#Add-AzureAnalysisServicesAccount -Credential $Credential -ServicePrincipal -TenantId $TenantId -RolloutEnvironment $RolloutEnvironment
ForEach($db in $asDBs)
{
Write-Output "Starting Backup..."
Backup-ASDatabase `
–backupfile ($db +"." + (Get-Date).ToString("ddMMyyyy") + ".abf") `
–name $db `
-server $Server `
-Credential $Cred
Write-Output "Backup Completed!"
}
You are correct that the issue is with multi-factor authentication. Since the point of multi-factor is the require interaction with a secondary source like your phone there is no way to automate the process.
I would suggest that you look into using service principle authentication for the purpose of taking backups. By using a service principle to your server you can allow for automated tasks to run without 2-factor while minimizing the security risk.
