In today’s digital world, data is one of the most valuable asset for organizations and individuals. Keeping it secure and protected is of utmost importance, especially when it comes to storing it in the cloud. But that is not enough!! In a connected world, businesses can’t afford a downtime even for a few minutes, let alone several hours or days. That’s why having a disaster recovery plan in place is critical to ensure that your business stays up and running in the event of a disaster or unexpected outage.
This is where Azure Backup and Azure Site Recovery solutions from Microsoft Azure comes into picture. Let us discuss both these in detail.

Why is backup and site recovery important?
Disasters, cyber attacks, human error, and other unexpected events can disrupt the business including data data loss. When this happens, businesses can face significant downtime and financial losses. Backup and site recovery is essential for ensuring the continuity of your business.
If a disaster occurs and your data is lost, you can restore it from your backup. This ensures that you don’t have to start from scratch and lose valuable business data. Additionally, backups can be used to recover individual files or volumes if something goes wrong with your operational system. This can help you get back up and running as quickly as possible.
Additionally, by having a site recovery plan in place, you can minimize the impact of a disaster on your business. Disaster recovery can also help you maintain continuity of operations and protect your data. If a disaster occurs, Site Recovery can automatically create a restore point and bring your site back online.
Azure Backup is a backup solution offered by Microsoft Azure that provides data protection for your cloud and on-premises resources. The backup process is automated, and you can schedule backups to occur at regular intervals to ensure that your data is always up-to-date. In the event of a disaster or data loss, you can quickly restore your data from the backup.
What does Azure Backup offer?
The solution supports a wide range of data sources, including virtual machines, SQL Server databases, and SharePoint sites. You can also choose from a variety of backup options, such as full, incremental, or differential backups.
One of the key features of Azure Backup is its scalability. You can easily add or remove backup resources as needed to accommodate changes in your data storage requirements. This means that you only pay for what you use, making it a cost-effective solution for businesses of all sizes.
Another key feature of Azure Backup is its security. All data stored in Azure is encrypted and protected with multiple security measures, including Azure Active Directory authentication and role-based access control. This ensures that your data is secure and protected at all times.
As per official Microsoft website, Azure backup provides following offerings:
- On-premises – Use the Microsoft Azure Recovery Services (MARS) agent backup files and folders. Or use the DPM or Azure Backup Server (MABS) agent to protect on-premises VMs (Hyper-V VMs and VMware) and other on-premises workloads
- Azure Virtual Machines – Back up entire Windows/Linux VMs (using backup extensions) or back up files, folders, and system state using the MARS agent.
- Azure Managed Disks – Back up Azure Managed Disks
- Azure Files shares – Back up Azure File shares to a storage account
- SQL Server in Azure VMs – Back up SQL Server databases running on Azure VMs
- SAP HANA databases in Azure VMs – Backup SAP HANA databases running on Azure VMs
- Azure Database for PostgreSQL servers – Back up Azure PostgreSQL databases and retain the backups for up to 10 years
- Azure Blobs – Overview of operational backup for Azure Blobs
Organizations can automate all of this using a backup policy in Azure.
Azure Site Recovery
Azure Site Recovery (ASR) is a comprehensive disaster recovery solution that provides business continuity and disaster recovery capabilities for both on-premises and cloud-based workloads. It can replicate your data and applications to the Azure storage account or managed disks, allowing you to recover your data and resume operations quickly in the event of a disaster.
The replication process is automated and can be configured to occur at regular intervals. The replication policy defines the settings for retention history of recovery points. In the event of a disaster, you can initiate a failover to the Azure cloud, which will allow you to continue your operations while you resolve the issue. Once the issue is resolved, you can initiate a failback to your on-premises environment.
What does Azure Site Recovery offer?
ASR provides a wide range of disaster recovery options, including replication, failover, and failback. It also provides the ability to test disaster recovery scenarios, so you can ensure that your disaster recovery plan works as expected. Site Recovery provides an additional layer of security for your data. Site Recovery also provides the ability to monitor and manage your sites from a central location.
Another key feature of ASR is its cost-effectiveness. With ASR, you only pay for what you use, so you can ensure that your disaster recovery solution fits within your budget. Additionally, ASR provides a single management console for both disaster recovery and backup, making it easy to manage all your data protection needs from one place.
A common use case is where Site Recovery is used to create a snapshot of your active site, which can be used in the event of a disaster. This ensures that all critical data is preserved and protected. If a disaster occurs and your site is down, Site Recovery can automatically bring your active sites back online.
It is important to note that ASR doesn’t support the move of Recovery Services Vault that has protected VM’s hosted in it.
By using Azure Public Clouds Backup and Site Recovery, you can achieve maximum efficiency and security for your business. These powerful solutions provide the peace of mind necessary to maintain high availability and continuity of operations in the event of a data loss.
