What is a Recovery Services Vault?
A Recovery Services Vault (RSV) is a storage entity in Azure used to store backup data and recovery configurations.
It’s the central hub for managing backups of:
-
Azure Virtual Machines
-
On-premises workloads (via MARS agent)
-
SQL Server, SAP HANA, file shares, and more
Azure Backup (via Recovery Services Vault)
-
Provides application-consistent backups, not just raw disk copies.
-
Supports scheduled backups with retention policies (e.g., keep daily backups for 30 days).
-
Data is encrypted and stored securely in the vault.
-
Integrated with Azure Policy for compliance.
Key Features
-
Granular recovery: Restore files, disks, or full VMs.
-
Geo-redundant storage (GRS): By default, backups are replicated to a paired region for durability.
-
Long-term retention: Keep backups for months or years (important for compliance).
-
Cross-region restore (if enabled): Allows restore in secondary region.
Confusion Buster 🚨
-
Snapshot vs Backup
-
Snapshot = crash-consistent, point-in-time, disk-level copy.
-
Backup = scheduled, long-term, application-consistent, stored in RSV.
-
-
Exam trap: If the question says “retain backups for 30 days,” snapshots alone won’t work — you need Azure Backup in a Recovery Services Vault.
Simple Example
A company configures Azure Backup:
-
Daily VM backups at midnight.
-
Data stored in a Recovery Services Vault.
-
Retention = 30 days.
-
In case of corruption, they can restore the VM or just individual files.
Exam Tip
-
If you see “long-term retention” → Recovery Services Vault.
-
If you see “quick rollback before patching” → Snapshot.
-
If scenario mentions “compliance, encryption, or central management” → RSV.
What to Expect in the Exam
-
Direct Q: “Which Azure feature stores long-term VM backups?” → Recovery Services Vault.
-
Scenario: “Company needs to retain daily backups for 90 days.” → Azure Backup with RSV.
-
Trick Q: “Snapshots can replace Azure Backup for compliance retention.” (False).
