You want to create manual permissions for your Azure account (service account) for Veeam Backup for Microsoft Azure or for a repository account. The Azure or service account is responsible for:
- Synchronization of virtual machines and disks with the Veeam Backup for Microsoft Azure database.
- Synchronization of subscriptions and storage accounts.
- Accessing virtual machines and its disks as a source of backup.
- Creating and deleting snapshots of virtual disks during backup.
The repository account can be used to store data in a different Azure Active Directory.
