Yes, Veeam takes a zero-trust approach to ensure the security of your data, including but not limited to encrypting data in transit and at rest, always using multi-factor authentication, and having strict security controls for users and administrators.
Veeam Data Cloud for Microsoft 365 includes service-level immutability capabilities on the primary backup, at no additional cost to the customer, based on how the data is protected.
The backup data lives in a virtually air-gapped location, hosted by Veeam on Azure, isolated and decoupled from the Microsoft 365 and/or customer infrastructure.
Customers also benefit from the inherent data security provided by Microsoft Azure at the storage level.
Once the data is backed up, it cannot be altered, tampered with, or deleted by users, including administrators or attackers.
Veeam Data Cloud uses local redundant storage (LRS), where three copies of customer data are stored in three separate disks within the primary Azure region.
You can learn more about Veeam’s fundamental principles and security capabilities within the security section of the user guide.

There are two licensing models – the Variable License Model and the Fixed License Model.
The Variable License Model makes it easy to protect your entire organization, including data that is not tied specifically to an individual Microsoft 365 user (ex. SharePoint sites or Teams public channels). This model provides the richest capabilities and automation, including automatic backup of all users and data, dynamically adds new users into the backup job, and enables administrators to customize their backup schedule. This model also makes it easy to add additional licenses when you need them.
The Fixed License Model has limited capabilities as it only protects the data associated with a specific number of users within your organization and requires manual configuration of backups.
Unlimited storage and the backup infrastructure are included at no additional cost within both models.
