.. _Introduction: Introduction ============ This guide explains how to set up Backup Gateway on Microsoft Azure to store backups in the Azure cloud. Typically, you will only need to create a VM with |product_name| on Azure, specifying the required details like VM user name and password, credentials for a partner account in Acronis Backup Cloud, and such. Once the virtual machine is running, you should be able to store backups in the Azure cloud, without having to log in to |product_name|.

Choose a correct disk template to ensure desired backup performance (see example in the next paragraph). Make sure to plan ahead, because disk template cannot be changed. In such a case, you will need to add a new disk with the correct template to the VM, add the new disk to the storage cluster, release the old disk from the storage cluster, and delete it from the VM. Performance and size of a local VM disk depends on its template. For example, a **STANDARD_DS1** virtual machine has the dedicated bandwidth of 32 MB/s for premium storage disk traffic. In turn, a **P10** premium storage disk can provide the bandwidth of 100 MB/s. If a **P10** premium storage disk is attached to a **STANDARD_DS1** virtual machine, its performance will be capped at 32 MB/s instead of the maximum 100 MB/s it can provide. For more details on premium storage, see `Azure documentation `__.
