Azure Backup is the service that you use to back up and restore your data in the Microsoft cloud. It replaces your existing on-premises or off-site backup solution with a cloud-based solution that is reliable, secure, and cost-competitive. It also helps protect assets that run in the cloud. Azure Backup provides recovery services built on a world-class infrastructure that is scalable, durable, and highly available.
Traditional backup solutions have evolved to treat the cloud as an endpoint similar to disks or tape. While this approach is simple, it is also limited. It does not take full advantage of an underlying cloud platform and translates to an inefficient, expensive solution. In contrast, Azure Backup delivers all the advantages of a powerful and affordable cloud backup solution. Below are some of the key benefits that Azure Backup provides.
- Automatic Storage Management
- Unlimited Scaling
- Multiple Storage Options
- Unlimited Data Transfer
- Data Encryption
- Application-consistent Backup
- Long-term Retention
- No capital expenditure is needed for on-premises storage devices. Azure Backup automatically allocates and manages backup storage, and it uses a pay-as-you-use consumption model.
- Take advantage of high availability guarantees without the overhead of maintenance and monitoring. Azure Backup uses the underlying power and scale of the Azure cloud, with its nonintrusive autoscaling capabilities.
- Choose your backup storage based on need:
- A locally redundant storage block blob is ideal for price-conscious customers, and it still helps protect data against local hardware failures.
- A geo-replication storage block blob provides three more copies in a paired datacenter. These extra copies help ensure that your backup data is highly available even if an Azure site-level disaster occurs.
- There is no charge for any egress (outbound) data transfer during a restore operation from the Backup vault. Data inbound to Azure is also free. Works with the import service where it is available.
- Data encryption allows for secure transmission and storage of customer data in the public cloud. The encryption pass phrase is stored at the source, and it is never transmitted or stored in Azure. The encryption key is required to restore any of the data, and only the customer has full access to the data in the service.
- Application-consistent backups on Windows help ensure that fixes are not needed at the time of restore, which reduces the recovery time objective. This allows customers to return to a running state more quickly.
- Rather than pay for off-site tape backup solutions, customers can back up to Azure, which provides a compelling tape-like solution at a low cost.
