Create a scheduled backup for a web app using PowerShell

This sample script creates a web app in App Service with its related resources, and then creates a scheduled backup for it.

If needed, install the Azure PowerShell using the instruction found in the Azure PowerShell guide, and then run Connect-AzAccount to create a connection with Azure.

$webappname="mywebapp$(Get-Random -Minimum 100000 -Maximum 999999)"
$storagename="$($webappname)storage"
$container="appbackup"
$location="West Europe"

# Create a resource group.
New-AzResourceGroup -Name myResourceGroup -Location $location

# Create a storage account.
$storage = New-AzStorageAccount -ResourceGroupName myResourceGroup `
-Name $storagename -SkuName Standard_LRS -Location $location

# Create a storage container.
New-AzStorageContainer -Name $container -Context $storage.Context

# Generates an SAS token for the storage container, valid for 1 year.
# NOTE: You can use the same SAS token to make backups in Web Apps until -ExpiryTime
$sasUrl = New-AzStorageContainerSASToken -Name $container -Permission rwdl `
-Context $storage.Context -ExpiryTime (Get-Date).AddYears(1) -FullUri

# Create an App Service plan in Standard tier. Standard tier allows one backup per day.
New-AzAppServicePlan -ResourceGroupName myResourceGroup -Name $webappname `
-Location $location -Tier Standard

# Create a web app.
New-AzWebApp -ResourceGroupName myResourceGroup -Name $webappname `
-Location $location -AppServicePlan $webappname

# Schedule a backup every day, beginning in one hour, and retain for 10 days
Edit-AzWebAppBackupConfiguration -ResourceGroupName myResourceGroup -Name $webappname `
-StorageAccountUrl $sasUrl -FrequencyInterval 1 -FrequencyUnit Day -KeepAtLeastOneBackup `
-StartTime (Get-Date).AddHours(1) -RetentionPeriodInDays 10

# List statuses of all backups that are complete or currently executing.
Get-AzWebAppBackupList -ResourceGroupName myResourceGroup -Name $webappname

# (OPTIONAL) Change the backup schedule to every 2 days
$configuration = Get-AzWebAppBackupConfiguration -ResourceGroupName myResourceGroup `
-Name $webappname
$configuration.FrequencyInterval = 2
$configuration | Edit-AzWebAppBackupConfiguration
