How to take one-time backup of Azure Virtual Machine

Hello, @Rancy Kaur !

How do I make a manual (one time) backup of my VM?

There are many different ways to back up a VM, however a snapshot of a virtual hard disk provides a full, read-only copy of a virtual hard disk (VHD) that can be used as a point-in-time backup. You can take a snapshot of both the OS and the data disk.

To create a snapshot using the Azure portal, complete these steps.

1. In the Azure portal, select Create a resource.
2. Search for and select Snapshot.
3. In the Snapshot window, select Create. The Create snapshot window appears.
4. For Resource group, select an existing resource group or enter the name of a new one.
5. Enter a Name, then select a Region and Snapshot type for the new snapshot. If you would like to store your snapshot in zone-resilient storage, you need to select a region that supports availability zones. For a list of supporting regions, see Azure regions with availability zones.
6. For Source subscription, select the subscription that contains the managed disk to be backed up.
7. For Source disk, select the managed disk to snapshot.
8. For Storage type, select Standard HDD, unless you require zone-redundant storage or high-performance storage for your snapshot.
9. If needed, configure settings on the Encryption, Networking, and Tags tabs. Otherwise, default settings are used for your snapshot.
10. Select Review + create.

Once you have the snapshot, you can either create a new VM using the OS snapshot or you can attach the data disk to an existing VM.

Other options to consider:

• VM Restore Points: An individual VM restore point is a resource that stores VM configuration and point-in-time application consistent snapshots of all the managed disks attached to the VM. VM restore points contain a disk restore point for each of the attached disks and a disk restore point consists of a snapshot of an individual managed disk.
• Full list of backup and restore options for virtual machines in Azure: This includes Azure Backup, Azure Site Recovery, Managed Snapshots (used in the answer above), and virtual machine restore points (previous point).
