Microsoft Azure provides two complementary solutions that address these needs:
- Azure Site Recovery (ASR)
- Azure Backup for Data Protection
Azure Site Recovery (ASR) is designed for disaster recovery. It continuously replicates your entire workloads (like virtual machines or physical servers) to another location. If your primary system fails (due to outage or disaster), you can quickly switch (failover) to the replicated system and keep your business running.
🔑 Key takeaways:
- Azure Site Recovery (ASR) enables business continuity by replicating workloads across Azure or regions.
- It supports Windows/Linux VMs, physical servers, VMware, Hyper-V, and cloud VMs.
- Test failovers can be run anytime without affecting production.
- Seamlessly integrates with Azure Monitor and Log Analytics for visibility.
- Cost-effective model — pay only for protected instances and storage.
Azure Backup is a service that backs up your data like files, folders, applications, and virtual machines so you can restore them if they get lost, deleted, or corrupted. It is focused on keeping copies of data for recovery.
- Azure Backup provides secure, scalable, and cloud-native backup for Azure and on-premises workloads.
- Supports a wide range: Azure VMs, SQL databases, files, and on-prem servers.
- Ensures end-to-end encryption with options like LRS, GRS, and RA-GRS for storage redundancy.
- Helps recover from accidental deletions, ransomware, corruption, or failures.
- Offers centralized policies, retention management, and compliance-driven cleanup.
👉 Azure Site Recovery = Make a copy ready to take over immediately in case of disaster
👉 Azure Backup = Save copies for later use
