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.
