A Recovery Services vault is a centralized storage entity in Azure used to protect workloads like virtual machines, SQL databases, and on-premises assets. During vault creation, administrators must select a storage replication type to define how data is protected. This critical choice must align with the disaster recovery plan because the setting becomes locked and cannot be changed once backup items are protected. Administrators can choose from the following storage options:
A comparison matrix of Azure Recovery Services vault storage replication options, contrasting Locally-redundant storage (LRS), Zone-redundant storage (ZRS), and Geo-redundant storage (GRS) across scope, cost, durability, and use cases.
Securing the vault requires configuring administrative boundaries and retention rules to prevent data loss. Role-Based Access Control (RBAC) manages user permissions and restricts vault operations to authorized administrators. To defend against accidental or malicious deletion, Soft Delete keeps deleted backup data in a deleted state for 14 days at no extra cost. For organizations requiring strict compliance, Immutable vaults can be enabled to freeze recovery points so they cannot be deleted before their scheduled expiration date.
By default, Azure secures vault data at rest using platform-managed keys, but organizations can choose customer-managed keys (CMK) stored in Azure Key Vault for complete control. The vault integrates with Azure Site Recovery to orchestrate virtual machine replication and disaster recovery across regions. For enhanced resiliency, Cross Region Restore (CRR) allows users to restore data to a secondary paired region at any time, provided the vault is configured with GRS. Additionally, Cross Subscription Restore provides the flexibility to recover resources to different subscriptions within the same Microsoft Entra tenant.
Deploying a Recovery Services vault requires evaluating several environment prerequisites before configuration begins. The vault must reside within a selected Subscription and Resource Group, and it must be deployed in the same geographic region as the target data sources. Administrators must select the storage replication type (GRS, LRS, or ZRS) before protecting any workloads, as the storage configuration locks permanently once data is present. GRS remains the default choice to replicate data to an Azure paired region, while LRS and ZRS offer localized alternatives.
To leverage advanced security features like customer-managed keys, specific infrastructure dependencies must be established before initiating any backups. The vault requires an enabled Managed Identity to authenticate with Azure Key Vault, which itself must have soft delete and purge protection enabled. The vault must also be granted precise permissions to access the encryption keys. Additionally, administrators should evaluate ransomware protections: soft delete is on by default, and immutable vault settings can be locked permanently to make them irreversible.
In enterprise environments, connectivity and identity boundaries influence vault planning and execution. On-premises servers utilizing the Microsoft Azure Recovery Services (MARS) agent depend on secure internet access and outbound endpoint connectivity to communicate with Azure Backup services. Across subscriptions, administrators must configure proper RBAC permissions to support Cross Subscription Restore, allowing data to transition between different subscription boundaries. These considerations must be evaluated early to ensure the vault can support diverse workloads across the entire enterprise.
To create a Recovery Services vault, administrators sign in to the Azure portal and navigate to the Business Continuity Center. Once the deployment completes, administrators should verify the resource in the notifications area and refresh the view if it does not appear immediately. Creating the vault involves several straightforward steps:
After deploying the vault, administrators define how and when data is protected by configuring backup policies. To set up protection, navigate to the Backup center, click to add a backup, choose a datasource type such as Azure Virtual machines, and associate it with the new vault. The backup policy defines the execution schedule and retention lifecycle for the recovery points. By integrating these vaults with Azure Advisor, administrators can continuously scan their environment to identify unprotected virtual machines and maintain compliance with backup requirements.
Ongoing vault management involves monitoring jobs, modifying replication settings, and protecting against data tampering. Before starting any backups, administrators can modify the default GRS setting to LRS by accessing the vault properties and updating the backup configuration. To safeguard backups against ransomware, administrators can enable immutable vaults, which guarantees that recovery points cannot be deleted early. If a regional disaster occurs, enabling Cross Region Restore allows administrators to initiate a failover and restore resources directly in the secondary paired region.

Administrators can choose from Locally-redundant storage (LRS), Zone-redundant storage (ZRS), and Geo-redundant storage (GRS). LRS provides a low-cost option within a single data center, ZRS replicates data across multiple availability zones in the same region, and GRS replicates data to a secondary paired region for maximum protection.
Soft Delete is a security feature that keeps deleted backup data in a deleted state for 14 days at no extra cost. It protects against accidental or malicious deletion by allowing administrators to recover backup data within the retention period.
The vault requires an enabled Managed Identity to authenticate with Azure Key Vault, and the Key Vault itself must have soft delete and purge protection enabled. The vault must also be granted precise permissions to access the encryption keys.
Cross Region Restore allows users to restore data to a secondary paired region at any time. This feature requires the vault to be configured with Geo-redundant storage (GRS) to enable restoration in the secondary region during regional disasters.
