What is Azure VM temporary storage?
- In Azure, every VM – regardless if Linux or Windows – gets a temporary disk assigned automatically. This temporary disk is located on the physical server (the hypervisor) where the Azure VM is hosted and is non-persistent. Disks used by the operating system or additionally added data disks are persistent disks and stored in Azure Storage.

- Azure VM’s can be moved from its current host to new host at any time due to maintenance, hardware failures or other reasons. In such an event, the data from the temporary storage will not preserve or moved to the new host.
