Azure Backup Service: The leading data recovery platform

by Nathan Zachary
Azure Backup Service

The Azure Backup Service offers fast, reliable, secure, and economical ways to back up and restore important data from Microsoft Azure Cloud. To protect the application data, it’s a scalable solution that ensures zero capital investment and minimal operational cost. Furthermore, it even retains the data for regulatory enforcement for up to 99 years. 

Resources covered under the backup service 

  • On-premise machines – Upload data, folders, and device state via the Microsoft Azure Recovery Services agent or by using the DPM or MABS agent to secure VMs (Hyper-V and VMWare) and other operating loads on site. 
  • Azure VMs – Backup entire Windows / Linux VMs or backup archives, directories, and machine state with a MARS handler. 
  • Azure File shares – Store Azure File shares in a storage account. 
  • SQL Server – Backup Azure Virtual Machine SQL Server databases. 
  • SAP HANA databases – Backup Azure Virtual Machine SAP HANA databases. 

Data backup location 

Azure stores a backup of data in a vault for recovery services. A vault is an online storage system used to store data in Azure, like backup data, recovery points, and backup policy. Office 365 Backup Solutions render application-consistent backups, providing that additional fixes are not required to restore the data. Service Recovery Vaults facility includes the following characteristics : 

  • Backup data can be conveniently stored with minimized handling overhead. 
  • In addition, backed objects, along with Azure Virtual Machines and on-premise machines can be tracked in a vault. 
  • Azure role-based access control enables us to manage vault access. 
  • Moreover, We have an option to display how to replicate data redundantly in the vault : 
  1. LRS (Locally redundant storage): To cover yourself from defects you can operate LRS in a data center.  
  2. GRS (redundant storage): GRS can be used to shield yourself from regional outages.  
  • Vault uses GRS (redundant storage) as a default Recovery Service. 

Policies of Azure Backup 

  • A policy of Azure backup defines as per vault. 
  • A backup policy can be created, to back up the workloads such as VMs, SQL servers, and file share. 
  • Numerous resources can be allocated to a policy.  
  • There are 2 elements to a policy: 
  1. Schedule: when to back up Schedule. At a particular point in time, it may be defined as “daily” or “weekly.” 
  2. Retention: How long will any backup be kept? For “daily,” “weekly,” “monthly,” and “yearly” backup points it can be specified. 
  • A “DefaultPolicy” for Azure Virtual Machine backups has been developed when a vault is created and used to back up Azure VMs. 

Types of Azure Backups 

  • Full Backup: It includes the whole data source and requires more network bandwidth than other backup types. It is mainly used for initial backups. 
  • Differential Backup: Blocks that have changed since the first complete backup are saved. It uses a small quantity of network and storage and does not retain a redundant copy of data that is unaltered.  
  • Incremental: This form of backup preserves only altered data blocks after the previous backup. It provides Wide capability and fast networking.  

Conclusion 

Azure provides a range of cloud backup services for your important data and operations. You can easily balance backup space and expenses by switching between several saving options. Apps4Rent provides managed Azure services and takes complete responsibility for the design, delivery, and management of system software, infrastructure configurations, and Azure service consumption. Apart from that they even provide a service of Windows Cloud PC with round-the-clock chat, phone, and email support.
