Azure VM Snapshot and Restoration

 

Restore VM disks and VM from the Azure Snapshot :

Azure is offering a simple feature called “Snapshot”. You can create a snapshot from an existing disk, even being up and running on a VM.

It is useful to restore the system with a snapshot if something goes wrong.In Azure, we can't revert back Azure VM directly, we should create disk or VM from that snapshot.

If you need to create a snapshot, just go to the disk and click on “Create snapshot”     

Home>Snap shot>Create>

Select the resource group of the VM>Select the Source disk of the VM>Create

Creating a new managed disk from a snapshot:

Home>Disks>+ Create>Source snapshot - Select the previously created snapshot>Create

Go to VM>Stop VM (deallocate) it. Click on the Disks option on the VM page. And Click on Swap OS disk.

Select the newly created OS disk from the drop-down menu and click on OK. Confirm the VM name down for which VM you are swapping OS Disk

Once the OS disk is swapped. As per the requirement. Click on the “X” at the end of the data disks to detach them. Once it is saved. You can power on the VM and validate.

Creating a virtual machine from a managed disk:

Home>Disks>Click on newly created disk>+ Create VM

Create a New VM with the managed disk with default settings to restore VM.
