Set Up Azure Blob Storage

Go to Azure Portal: https://portal.azure.com

Create a Storage Account:

• Click Create a Resource > Storage > Storage Account
• Use Standard performance and Hot access tier for frequent access

Create a Container:

• After the storage account is deployed, go to it and select Containers
• Add a new container (e.g., backups)
• Set public access to Private

Create an Azure Function

Create a Function App:

• Go to Create a resource > Compute > Function App
• Choose Python 3.10, use Consumption Plan to save costs

Deploy Code:

• Use VS Code with the Azure Functions Extension
• Create a new function with an HTTP trigger
• Example Python code to back up a file:

import logging
import azure.functions as func
from azure.storage.blob import BlobServiceClient
import os

def main(req: func.HttpRequest) -> func.HttpResponse:
    file_name = req.params.get('file')
    if not file_name:
        return func.HttpResponse("Please pass the file name as ?file=", status_code=400)

    connection_str = os.getenv("AzureWebJobsStorage")
    blob_service_client = BlobServiceClient.from_connection_string(connection_str)
    container_client = blob_service_client.get_container_client("backups")

    # Simulate local file (replace with real file path or stream)
    local_path = f"/home/site/wwwroot/temp/{file_name}"
    if not os.path.exists(local_path):
        return func.HttpResponse(f"{file_name} not found", status_code=404)

    with open(local_path, "rb") as data:
        container_client.upload_blob(name=file_name, data=data, overwrite=True)

    return func.HttpResponse(f"{file_name} backed up successfully.")

Set Environment Variable:

Add AzureWebJobsStorage in your Function App’s configuration (it's already set if you chose a storage account during creation)

Automate It with Logic Apps

If you want a no-code trigger, use Azure Logic Apps to call your function on a schedule.

Go to Logic Apps > Create

Select Blank Logic App

Add a Recurrence trigger (e.g., daily at 2 AM)

Add HTTP action:

• Method: GET
• URL: Your function URL (include ?file=filename.txt)

Save and Test

Test the Backup System

Upload a file to your local directory or GitHub

Call your function URL (via browser or Logic App)

Go to your Azure Blob Storage > Container

Confirm the file was uploaded
