What is Git?

Git is distributed version control software.

Version Control is the ability to save and track changes over time, without interfering with previous versions. As the software is distributed, it means all users can have a copy of an entire repository, containing all commits, branches, and files.

There are a few things you should know before we dive in:

  • Branches are lightweight and cheap, so it’s OK to have many of them
  • Git stores changes in SHA hashes, which work by compressing text files. That makes Git a very good version control system (VCS) for software programming, but not so good for binary files like images or videos.
  • Git repositories can be connected, so you can work on one locally on your own machine and connect it to a shared repository. This way, you can push and pull changes to a repository and easily collaborate with others.
Why Use Git?

Version Control is important in development, whether for software, or simply for developing your automation scripts. Without it, you can risk losing your work. By using Git, you can make a “commit”, which is a snapshot of your point in time work. This provides you the capability to rollback to previous commits if needed.

Authenticating to GitHub and creating a repository

To make life easier, I am going to use GitHub as my main source control platform.

I am going to start off creating a repository on the GitHub website. This is simple to complete, so I will not document the steps, but you can view this page for more information.

I would also recommend at this point setting up the authentication with GitHub as well to your local CLI.

Cloning a Repository locally

Once our repository is created, we start off by cloning the repository locally.

git clone {url}

#Example
git clone https://github.com/saintdle/veducate-git-example.git

git clone

Create and commit our first file

What is Veeam Backup for Azure?

If we look at the Microsoft document “Shared responsibility in the cloud“, we can see the very open comment;

  • Regardless of the type of deployment, the following responsibilities are always retained by you:
    • Data
    • Endpoints
    • Account
    • Access management

So, if you are always responsible for your data, that means you are responsible for protecting it, at both a security and backup point of view.

Veeam Backup for Azure is a turnkey solution that provides you a backup solution which can quickly and securely protect your data, available within the Azure Marketplace itself. Removing the need to spend hours on designing a solution and configuring the software.

Architecture

Veeam Backup for Azure Architecture

There are three main components;

  • Controller Server

A Linux VM deployed into Azure, which runs the Veeam Backup for Azure software.

  • Backup Repositories

Azure blob storage accounts where your Azure VM backups will be saved. The following storage accounts are supported currently;

  • Workers

These are Azure VMs which are deployed automatically or manually by Veeam Backup for Azure server and are used for backing up and restoring the data. There is the capability to scale up and scale down the number of workers as needed.

The Azure region that worker VMs are deployed to, depend on the storage account they are linked to.

Each worker can process a single VM at a time, if a worker is idle for 10 minutes or more, then it is decommissioned (when setup to auto scale). Worker VMs, run the following services; A Worker service, which is responsible for fetching data from Azure; File-level recovery service, used for mounting data from a backup to the worker VM to initiate file-level recovery.

Deploy Veeam Backup for Azure from the Azure Marketplace

The options to access the solution, which is driven via a web portal;

  • Direct via Public IP address
    • I recommend setting up firewall rules if you do this
  • Accessing the portal via a private IP address via the use of a VPN or Azure Express route.
    • If you need a VPN solution, check out VeeamPN.
    • This removes the need to publicly expose the solution.

Veeam Azure Deploy from Marketplace Complete

Logging into the Veeam Backup for Azure Console

Your first login, you’ll provide the username and password configured during the deployment from the marketplace.

In my example, I will be using the publicly assigned IP address to log into the Portal UI. Upon first logon you will need to accept the EULA.

The interface is heavily wizard driven, which makes it simple to use and consume as a solution. If you’ve used Veeam Availability Orchestrator in the past, you’ll recognise similarities with the interface.

Logging into the solution for the first time, you’ll see this getting started screen, which makes it easy to understand how to operationalise the solution and start protecting your data.

Connecting to your Microsoft Azure Subscriptions and Storage Accounts

From the getting started page, we’ll click the first task to connect our Veeam Backup for Azure solution to our Microsoft Azure platform, which takes us to the screen shown below.
