Azure Backup is the Azure-based service you can use to back up (or protect) and restore your data in the Microsoft cloud. Azure Backup replaces your existing on-premises or off-site backup solution with a cloud-based solution that is reliable, secure, and cost-competitive. Azure Backup offers multiple components that you download and deploy on the appropriate computer, server, or in the cloud. The component, or agent, that you deploy depends on what you want to protect. All Azure Backup components (no matter whether you’re protecting data on-premises or in the cloud) can be used to back up data to a Recovery Services vault in Azure.
Why use Azure Backup
Automatic Storage Management
Hybrid environments often require heterogeneous storage – some on-premises and some in the cloud. With Azure Backup, there is no cost for using on-premises storage devices. Azure Backup automatically allocates and manages backup storage, and it uses a pay-as-you-use model. Pay-as-you-use means that you only pay for the storage that you consume.
Multiple Storage Options
An aspect of high-availability is storage replication. Azure Backup offers two types of replication: locally redundant storage and geo-redundant storage. Choose the backup storage option based on need:
- Locally redundant storage (LRS) replicates your data three times (it creates three copies of your data) in a storage scale unit in a datacenter. All copies of the data exist within the same region. LRS is a low-cost option for protecting your data from local hardware failures.
- Geo-redundant storage (GRS) is the default and recommended replication option. GRS replicates your data to a secondary region (hundreds of miles away from the primary location of the source data). GRS costs more than LRS, but GRS provides a higher level of durability for your data, even if there is a regional outage.
Unlimited Data Transfer
Azure Backup does not limit the amount of inbound or outbound data you transfer. Azure Backup also does not charge for the data that is transferred. However, if you use the Azure Import/Export service to import large amounts of data, there is a cost associated with inbound data. Outbound data refers to data transferred from a Recovery Services vault during a restore operation.
