Azure Backup is the Microsoft’s cloud-based service you can use to back up and restore your data in Microsoft Azure. Azure Backup offers multiple ways to deploy the solution based on what you want to backup. All solution options, regardless of on-premises or cloud resources, can be used to backup data to a Recovery Services vault in Azure. Within the Azure portal in the Recovery Services vault, Microsoft provides a simple wizard to help determine which solution to deploy based on your needs. You simply select either On-Premises or Azure as well as what you want to backup and you are provided with instructions based on the appropriate solution required. There are four primary ways to utilize Azure Backup. Each of these options are describe below:
- Azure Backup Agent
- System Center Data Protection Manager
- Azure Backup Server
- Azure IaaS VM Backup
Azure Backup Agent
Azure Backup Agent is a server-less agent that installs directly on a physical or virtual Windows Server. The servers can be on-premises or in Azure. This agent can backup files, folders and system states directly to an Azure Recovery Services Vault up to 3 times per day. This agent is not application aware and can only restore at the volume level. Also, there is no support for Linux.
System Center Data Protection Manager (DPM)
DPM provides a robust enterprise backup and recovery solution with the ability to backup on-premises and in Azure. A DPM server can be deployed on-premises or in Azure. DPM can be used to backup Application-aware solutions such as SQL Server, SharePoint, and Exchange. DPM can also backup files and folders, System states, Bare Metal Recovery (BMR), as well as entire Hyper-V or VMWare VMs. DPM can store data on disks, tape, or within Azure Recovery Services Vault. DPM supports backups of Window 7 or later client machines and Windows 2008 R2 SP1 or later servers. DPM cannot backup any Oracle, DB2 etc. workloads.Support for Linux-based machines is based on Microsoft’s endorsed list found here
Azure Backup Server
Microsoft Azure Backup Server (MABS) is merely a slightly scaled-down version of System Center DPM. MABS is for customers that do not already have System Center DPM. MABS does not require any System Center licenses. MABS requires an Azure subscription to be active always. The primary differences between MABS and System Center DPM are as follows:
- Does not support tape backups
- No centralized System Center administration
- Unable to back up another MABS instance
- Does not integrate with Azure Site Recovery Services
Azure IaaS VM Backup
All Azure VMs can be directly backup up to a Recovery Services Vault with no agent installation or additional infrastructure required. You can also backup all attached disks to a VM. This works for both Windows and Linux VMs. You can back up only once per day and only to Azure; on-premises backup is not supported. VMs are only restored at disk level. DellEMC’s approach is far ahead than what is being offered by native Azure options. We have multiple options which can be used to protect workloads in Azure:
1. Cloud Snapshot Manager for Azure:
This is a SaaS based offering which allows protection of Azure managed VMs to be protected on a snapshot basis in Azure object storage. The licensing is based on number of instances on subscription basis. No backup server or infrastructure is required for such configuration. More importantly, customer can have multiple Azure accounts and subscriptions and all can be protected and managed by a single CSM console User Interface. It literally takes 5-7 mins to start your first backup.
2. NetWorker and Data Domain / Avamar and Data Domain:
NetWorker and Avamar are DellEMC’s flagship software which can be deployed in a Azure VM and can be made to write to Data Domain Virtual Edition in Azure. NetWorker and DD allow customers to have no media servers by virtue of client direct and since DD has a single deduplication pool the storage savings are magnanimous. With continued investment in DD engineering we have now the functionality to deploy DD in Azure on object Storage which allows for more storage savings than ever. Since we are leveraging NetWorker and Avamar we get the functionality to integrate with any application or database that is hosted in Azure. The main benefits from such a solution are below:
- No media servers required in Azure
- Ability to protect data in de-duplicated format in Azure object storage
- Wide application and database support.
- Enterprise level backup performance and de-duplication
- Both Data Domain and Avamar are available in Azure marketplace.
3. Data Domain and DDBEA:
Data Domain can protect workloads without integrating with any backup software and can protect both SQL and No SQL databases, by leveraging BOOST and BOOSTFS integration respectively. Customer can run the BOOSTFS tool and with help of DellEMC make any customer application write backups on DD with source based deduplication as well. DDVE is available up to 96 TB in a single instance in Azure, the capacity of 96 TB comes from Azure BLOB storage so it is extremely cost efficient.
