The Management Plane in Azure Backup is responsible for managing the backup infrastructure, including the backup policies, storage management, and configuration of backup and restore tasks.
Within the management plane, Recovery Services Vaults, Backup Vaults, and Backup Center play crucial roles in organizing, storing, and managing backup data.
Let’s explore these components in detail.
Recovery Services Vault vs Backup Vault
Azure Backup offers two primary types of vaults for managing backups: Recovery Services Vault and Backup Vault.
These vaults are used to store backup data and configurations for Azure and on-premises workloads.
Recovery Services Vault (Recommended)
The Recovery Services Vault is the modern, unified solution for managing backup and disaster recovery across Azure and hybrid workloads.
It supports all of Azure’s backup features and provides centralized management for multiple types of backup workloads, including virtual machines (VMs), Azure file shares, SQL databases, and on-premises systems.
Key Features of Recovery Services Vault
Unified Management: It centralizes the management of backup and recovery tasks for a variety of services (Azure VMs, SQL databases, on-premises machines, etc.).
Centralized Backup: All backup data and configurations are managed in a single place, offering easy access to backup jobs, recovery points, and retention policies.
Cross-Region Support: Supports geo-replication, allowing your backups to be stored in geographically redundant locations.
Backup Policies: You can define backup and retention policies that apply to multiple Azure resources (e.g., VMs, SQL databases, file shares).
Monitoring and Alerts: Integrated with Azure Monitor, enabling proactive monitoring, alerting, and troubleshooting.
Disaster Recovery (DR): Also used for Azure Site Recovery (ASR) to handle disaster recovery scenarios.
Multi-workload Backup: Supports backup of Azure VMs, on-premises VMs, Azure file shares, and SQL databases. It integrates with Azure Automation for additional control and custom workflows.
Typical Use Cases
Backup of Azure Virtual Machines (VMs), SQL databases, and Azure File Shares.
Hybrid backup scenarios: Backing up both on-premises machines and Azure resources.
Backup for compliance and long-term retention: Using retention policies and geo-redundancy to meet regulatory requirements.
Backup Vault (Deprecated)
The Backup Vault is an older backup management service used primarily for backing up workloads like Azure VMs and Azure Classic Storage.
However, Backup Vault has been deprecated in favor of the Recovery Services Vault and is now recommended only for backward compatibility with legacy workloads.
Key Features of Backup Vault
Azure Classic VM Backup: Primarily used to back up classic Azure VMs and storage accounts.
Limited Features: Lacks some of the modern features of the Recovery Services Vault, such as cross-region replication, better integration with Azure Resource Manager (ARM), and more flexible policies.
Deprecation Notice
As of 2020, Microsoft has gradually phased out the Backup Vault, and customers are encouraged to migrate to Recovery Services Vault for better scalability, functionality, and support for newer workloads.
Backup Center
The Backup Center is a centralized management dashboard in Azure designed to provide visibility and control over your entire backup estate.
It brings together backup data from Recovery Services Vaults across different subscriptions and regions into a single interface.
Key Features of Backup Center
Centralized Backup Management
Provides a unified, centralized view of all your backups across multiple Recovery Services Vaults, subscriptions, and regions.
Allows you to monitor, configure, and manage backup policies for various resources like VMs, databases, file shares, and on-premises workloads.
Single Pane of Glass for Monitoring
Backup Center integrates with Azure Monitor, providing a consolidated view of backup jobs, their health, and status.
You can view success/failure rates, schedule failures, and backup history for all your backups.
Allows setting up and receiving backup alerts, ensuring you’re notified of any issues, failures, or critical events.
Backup Recommendations
The Backup Center offers recommendations to help you optimize backup strategies, such as setting up more frequent backups, changing retention policies, and reviewing data protection status.
Policy Management
You can manage and configure backup policies across different Azure resources in a streamlined manner.
Backup policies define the frequency of backups, the retention period for backup data, and the location of backups.
Allows configuring backup policies for specific workloads, such as Azure VMs, SQL databases, or Azure file shares.
Restore Management
Backup Center provides an intuitive interface for restoring data from any backed-up resource.
It consolidates all restore operations, making it easier to locate and restore backup data across multiple Recovery Services Vaults.
You can also monitor ongoing restore jobs, ensuring that restore operations are completed successfully.
Security and Compliance
It includes security features like ransomware protection, backup encryption, and immutability to ensure that backup data is secure and protected against unauthorized changes or malicious attacks.
Compliance tracking is also available, allowing you to manage and monitor backup data retention, adhering to governance and regulatory requirements.
Integration with Azure Lighthouse
For Managed Service Providers (MSPs), Azure Lighthouse enables managing backup operations across multiple tenants from a single Azure subscription.
Backup Health and Risk Assessment
It includes features for health assessments and identifies potential risks to backup operations.
For instance, it can point out issues such as failed backups or suboptimal configurations.
Proactively helps identify and mitigate potential backup issues before they impact data availability.
How Recovery Services Vault, Backup Vault, and Backup Center Fit Together
Here’s a breakdown of the roles these components play in the overall Azure Backup Management.
| Component | Role | Use Case |
|---|---|---|
| Recovery Services Vault | Centralized location for storing backup data and configuration for Azure and hybrid environments. | Backup of Azure VMs, SQL databases, Azure file shares, and on-premises machines. |
| Backup Vault | Deprecated solution used for older workloads like classic VMs and older storage accounts. | Legacy Azure Classic VM backup (not recommended for new deployments). |
| Backup Center | Centralized dashboard for managing and monitoring backups across all Recovery Services Vaults. | Provides a unified view of backup status, health monitoring, alerts, and restore. |
Best Practices for Using Recovery Services Vault and Backup Center
Centralized Management with Backup Center
Use Backup Center to monitor and manage backup configurations across multiple subscriptions, regions, and workloads.
Consolidate all backup management into Backup Center to get a unified overview of your backup health and status.
Migration to Recovery Services Vault
If you are still using Backup Vault for legacy workloads, consider migrating to the Recovery Services Vault for better features, including geo-redundancy, integrated backup policies, and support for hybrid scenarios.
Set Up Backup Policies
Create and configure backup policies in the Recovery Services Vault to ensure regular and efficient backups.
Define the frequency of backups (e.g., daily, weekly) and retention periods to meet your business needs.
Enable Geo-Redundancy
For high availability and disaster recovery, ensure that geo-redundant storage (GRS) is enabled for your Recovery Services Vault.
This will replicate your backup data to a secondary Azure region to protect against regional failures.
Monitor Backup Jobs
Use Backup Center to monitor the health of your backup jobs.
Set up alerts and proactively manage backup failures or issues to ensure data is always protected and ready for recovery.
