Create a scheduled backup for an App Service app using CLI

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

If you don't have an Azure subscription, create a free account before you begin.

Use Azure Cloud Shell

Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. Cloud Shell lets you use either bash or PowerShell to work with Azure services. You can use the Cloud Shell pre-installed commands to run the code in this article without having to install anything on your local environment.

To launch Azure Cloud Shell:

Option Example/Link
Select Try It in the upper-right corner of a code block. Selecting Try It doesn't automatically copy the code to Cloud Shell. Example of Try It for Azure Cloud Shell
Go to https://shell.azure.com or select the Launch Cloud Shell button to open Cloud Shell in your browser. Launch Cloud Shell in a new window
Select the Cloud Shell button on the top-right menu bar in the Azure portal. Cloud Shell button in the Azure portal

To run the code in this article in Azure Cloud Shell:

  1. Open Cloud Shell.
  2. Select the Copy button on a code block to copy the code.
  3. Paste the code into the Cloud Shell session with Ctrl+Shift+V on Windows and Linux, or Cmd+Shift+V on macOS.
  4. Press Enter to run the code.

If you choose to install and use the CLI locally, you need Azure CLI version 2.0 or later. To find the version, run az --version. If you need to install or upgrade, see Install the Azure CLI.

Sample script

#!/bin/bash

groupname="myResourceGroup"
planname="myAppServicePlan"
webappname=mywebapp$RANDOM
storagename=mywebappstorage$RANDOM
location="WestEurope"
container="appbackup"
expirydate=$(date -I -d "$(date) + 1 month")

# Create a Resource Group 
az group create --name $groupname --location $location

# Create a Storage Account
az storage account create --name $storagename --resource-group $groupname --location $location \
--sku Standard_LRS

# Create a storage container
az storage container create --account-name $storagename --name $container

# Generates an SAS token for the storage container, valid for one month.
# NOTE: You can use the same SAS token to make backups in App Service until --expiry
sastoken=$(az storage container generate-sas --account-name $storagename --name $container \
--expiry $expirydate --permissions rwdl --output tsv)

# Construct the SAS URL for the container
sasurl=https://$storagename.blob.core.windows.net/$container?$sastoken

# Create an App Service plan in Standard tier. Standard tier allows one backup per day.
az appservice plan create --name $planname --resource-group $groupname --location $location \
--sku S1

# Create a web app
az webapp create --name $webappname --plan $planname --resource-group $groupname

# Schedule a backup every day and retain for 10 days
az webapp config backup update --resource-group $groupname --webapp-name $webappname \
--container-url $sasurl --frequency 1d --retain-one true --retention 10

# Show the current scheduled backup configuration
az webapp config backup show --resource-group $groupname --webapp-name $webappname

# List statuses of all backups that are complete or currently executing
az webapp config backup list --resource-group $groupname --webapp-name $webappname

# (OPTIONAL) Change the backup schedule to every 2 days
az webapp config backup update --resource-group $groupname --webapp-name $webappname \
--container-url $sasurl --frequency 2d --retain-one true --retention 10

Clean up deployment

After the sample script has been run, the following command can be used to remove the resource group and all resources associated with it.

az group delete --name myResourceGroup
