In this blog, we are going to cover Snapshot in Azure, Azure Managed Disk Snapshot & Creating Snapshot from Azure Portal.
Topics we’ll cover:
What is a Snapshot in Azure
A snapshot is a representation of an object at a specific point in time. A snapshot incurs billing for the incremental size of the data it holds.
A snapshot is a full read-only copy of a virtual hard disk (VHD). You can take a snapshot of an OS or data disk VHD to use as a backup or to troubleshoot virtual machine (VM) issues.
You can store full snapshots and images for Standard SSD Managed Disks on Standard HDD storage. You can choose between locally-redundant (LRS) and zone redundant (ZRS) snapshot options.
Keep these best practices in mind when creating and using Azure snapshots:
- Where conceivable, make the Azure preview when the machine is fueled off – – it makes the disk more steady. In the event that the VM isn’t controlled off as of now, it will be the point at which the depiction is taken.
- Try not to save previews for longer than required; they cost cash and can adversely influence execution.
- Try not to involve previews as a drawn-out backup procedure. All things considered, utilize Azure Backup – – it doesn’t need human interaction, which decreases human blunder and different dangers.
We can use an Azure Snapshot to complete tasks such as:
- Custom backup.
- Restore and rebuild a VM.
- Disaster recovery.
- Overwrite OS disks without recreating a VM.
- Make a copy of a VM.
- Troubleshoot VM issues.
Azure Managed Disk Snapshot
Azure disk snapshot include is regularly mistaken for backup. It’s one of the speedy backup strategies to investigate VM issues or test the arrangement changes by keeping the protected snapshot. A managed disk snapshot is a read-only crash-consistent full copy of a managed disk that is stored as a standard managed disk by default. With snapshots, you can back up your oversaw disks anytime
The greatest contrast is that we can utilize Azure Backup to reestablish VM straightforwardly. Be that as it may, to reestablish VM, we need to utilize the snapshot to make OS disk and afterward utilize this OS disk to make another VM.
Creating Snapshot in Azure Portal
Before starting please Create one Resource Group, one Virtual Network, and a subnet, also deploy one VM.
1. In the Azure portal, Go to Virtual Machine, you see you’re all VMs, select your Virtual Machine from which you want to create your snapshot.
2. On Virtual machine K21vm, page under the Settings section click Disks blade.
3. Now on the Disk page you will get to see that our VM OS disk is attached. Click on your VM OS disk under the OS disk.
4. Now you are inside your K21vm OS disk page, click on Create snapshot.
5. Now Create snapshot page will appear, fill in the following detail: under the Basics tab.
- Select your active Azure Subscription.
- Select your resource group K21321.
- Fill up instance details Name.
- The region is auto-selected based on your resource group
- Choose your Snapshot Type, Full – make a complete read-only copy of the selected disk.
6. From the dropdown menu select Zone-redundant, click on the next tab.
7. Next is the Encryption Tab, choose encryption type as (Default) Encryption at-rest with a platform-managed key. Select Review.
8. Review your Snapshot Details, validate them, click on Create.
9. On the next page wait for a few minutes, you see your Snapshot deployment is complete.
