VM Image from a Snapshot

These tasks can also be handled in the Azure portal's GUI. Once you have created a new data carrier from a snapshot, simply click on it in the portal. The Create VM entry is at the top of the disk details. You can use this menu item to create new VMs manually from data carriers, create a data carrier from the snapshot, and create a VM from the data carrier.

Another option in the Azure GUI is Create VM image version . VM images enable the management and provisioning of consistent and reusable virtual machine configurations. A VM image acts as a template that contains a preconfigured operating system, as well as applications, settings, and data.

By creating and managing different image versions, you can ensure that VMs are consistent and available and use identical software versions. Each image version is uniquely referenced, ensuring the traceability and consistency of deployments. In this way, you can manage different versions of an image – for example, to separate development, test, and production environments or to manage updates and patches in a targeted way. This approach is a good way to standardize and manage even more complex VM infrastructures efficiently.

The individual tasks can be automated by PowerShell and the Azure Cloud Shell. You can create scripts or use the GUI on the Azure portal. Doing so helps you provision identical Azure VMs with just a few clicks. The PowerShell and Azure Cloud Shell commands are not overly complicated, and they offer many options. For example, you can create numerous VMs with identical configurations in just a few minutes or restore a VM from snapshots.

Conclusions

The use of snapshots in Azure offers a flexible and efficient way of backing up, restoring, and cloning virtual machines. Snapshots capture the state of a VM at a specific point in time – without interrupting ongoing operations, which is particularly important in production environments. The incremental backup capability that snapshots offer reduces storage requirements and means that backups can be created quickly or that development and test environments can be generated quickly.

On top of all this, snapshots facilitate the management of large infrastructures and offer efficient options for restoring VMs or creating new instances. Integration with tools such as Azure Automation and the use of Azure Private Link can significantly enhance security and improve automation in snapshot management. All told, snapshots in Azure are an important building block for backup and recovery strategies and for rapid VM scaling and provisioning.
