Plan Backup and Disaster Recovery for Azure IaaS Disks

Community Manager

We recently posted an article explaining the Backup and DR for Azure Disks. We encourage Azure IaaS users to refer to this document for planning the right Backup and Disaster Recovery (DR) methodology for their disks. Following are a few considerations.


We are excited to report that Azure has consistently delivered enterprise-grade durability for IaaS disks, with an industry-leading ZERO % Annualized Failure Rate. This means that Azure has never had a permanent failure of an IaaS disk. For Azure customers, it directly translates into lower cost, better reliability, and smoother operations for the critical applications running on Azure. For example, you don’t have to build costly RAID solutions with redundancy in most cases because Azure protects your data with three redundant copies stored locally. Even if two different hardware components that hold your disks fail at the same time, durability of your data is protected and Azure automatically spawns new replicas in the background to replace the lost copies. We built the Azure disks platform with the core consideration that protecting the data is critical to any storage platform. With Azure disks, you won’t have to constantly worry about losing your disks in the cloud.
