What is the primary purpose of Azure Backup Recovery Services vaults?

The primary purpose of Azure Backup Recovery Services vaults is to store recovery points for restoring Azure VMs or disks. This service is designed to provide a secure and scalable way to back up and restore data across Azure workloads. When backups are taken, recovery points are created at specified intervals. These recovery points allow administrators to restore their virtual machines or disks to a specific moment in time, providing essential data protection and disaster recovery capabilities.

In particular, Azure Backup Recovery Services vaults not only store these recovery points but also manage the data retention policy and provide features such as encryption and deduplication, making them crucial for maintaining the integrity and security of backup data.

The other answer choices relate to functionalities that do not represent the primary role of a Recovery Services vault. For example, managing access to subscriptions is typically handled through Azure Active Directory and role-based access control, while network settings and system performance monitoring are matters of network configurations and monitoring services, respectively. Thus, while they are important in their own contexts, they do not pertain to the core purpose of Recovery Services vaults in Azure.
