However, deduplication is available when you deploy System Center DPM or Azure Backup Server on a Hyper-V virtual machine. Disk Deduplicationĭeduplication is not available in Azure for any Backup component. However, storing the data without compression means you can achieve a faster restoration. Transferring data without compressing it means you’ll need higher levels of storage. Instead, it copies all backup data from your storage account to the Recovery Services vault in the same region, without compressing the data while transferring it. The VM extension is the only one that doesn’t use compression. In order to reduce the required storage space, backups are compressed. The table below summarizes the availability or support of the various features in each Azure Backup component. What Are the Features of Each Backup Component? The following table shows the Azure Backup components that have support for Linux. Which Applications and Workloads Can Be Backed Up? The following table shows what you can protect with each Azure Backup component. Which Azure Backup Components Should I Use? The table below show the maximum backup frequency for each component. However, Azure Backup has a limit of 9999 recovery points per protected instance. There is no limit to the length of time data can remain in a Recovery Services vault, so they can be used for both short, and long term data retention. The use of application-consistent data means that restoration time is reduced substantially. This means that a recovery point has all the required data to restore the backup copy, so additional fixes are not required. If you need to restore any of the data, you’re the only one who has the encryption passphrase. The encryption passphrase is stored locally and is never transmitted or stored in Azure. Data EncryptionĪzure Backup includes data encryption to ensure that your data is transmitted and stored securely. However, if you’re using the Azure Import/Export service to import large amounts of data, inbound data will accrue a cost. Outbound data means data which is transferred from a Recovery Services vault while carrying out a restore operation. Unlimited Data TransferĪzure Backup does not place limits on the amounts of inbound or outbound data that you transfer. Which one you choose, or a combination, will depend on your storage and back up needs. There are two types of replication in Azure Backup- locally redundant storage (LRS) and geo-redundant storage (GRS). You can get information about events by setting up alerts, if you wish. You have no maintenance or monitoring overheads. See below for details of cost as of Nov 2018:Īzure Backup has high-availability. It also allocates and manages backup storage and uses a pay-as-you-use model. Azure Backup doesn’t charge for on-site storage devices. Other cloud storage solutions can mean that you end up paying for storage which you don’t need or the wrong type of storage for your business.ĭepending on your business needs, you may want storage on-site as well as in the cloud. However, this approach doesn’t take full advantage of an underlying cloud platform. Traditionally backups to the cloud have treated the cloud as a storage destination, similar to disks or tape. GRS is more expensive than LRS, but it means that your data is protected even in the event of an outage in your region. In contrast, GRS copies your data to a secondary region, which is hundreds of miles away from the source data. LRS will protect your data from local hardware failures. All these copies exist in the same region. LRS copies your data three times in a storage scale unit in a datacenter. When considering where to store your data, you can use geo-redundant storage (GRS) or locally redundant storage (LRS). With each Azure subscription, you can create up to 500 Recovery Service vaults. Recovery service vaults can be used to hold backup data for Azure services as well as on-site servers and workstations. This is an online storage entity in Azure and is used to hold recovery points, backup copies and backup policies. All of these components can be used to back up data to a Recovery Services vault in Azure, regardless of whether you’re protecting data on your premises or in the cloud. There are multiple components in Azure Backup which can be downloaded and deployed depending on what you want backed up. Azure Backup is a reliable, safe and competitively priced cloud-based backup solution which can be used to replace on-premises or off-site backup solutions. Azure Backup is the Azure-based service which you can use to back up and restore your data in the Microsoft cloud.
