8/24/2023 0 Comments Azure take snapshot of vmManaged snapshots is a manual way to taking snapshot of the virtual machines. ASR on the contrary provides high RPO since a snapshot is taken every 5 minutes and you will have the most recent data available in case of disaster. But you might have to compromise on the RPO since this only allows one scheduled backup and 3 manual backups.Īzure Site Recovery (ASR) is also an automated way to configure disaster recovery of the virtual machine, however this doesn’t provide long term retention, and it can be retained only upto 15 days. Azure backup provides you an option to chose flexible retention, you can also configure GRS enabled vault to ensure your backups are prone to geographic disasters. In my opinion Azure backup is the best bet to ensure you have a restore point available in case of any disaster. What’s the agreed SLA with the vendor/client.Conclusion:Ĭhoosing the correct option can always be tricky but it all boils down to below questions: To restore a VM, restore all relevant disks and attach them to a new VM. Once created, VM restore points can then be used to restore individual disks. To save space and costs, you can exclude any disk from your VM restore points. Each restore point stores a VM’s configuration and a snapshot for each attached managed disk. The restore point collection itself contains individual restore points for specific VMs. You can use the API to create a VM restore point collection. This approach is most often used by independent software vendor (ISVs) or organizations with a relatively small number of VMs to manage. Virtual machine restore pointsĪt this time, you can use Azure REST APIs to back up and restore your VMs. For example, if you create a snapshot of a managed disk with provisioned capacity of 64 GB and actual used data size of 10 GB, snapshot will be billed only for the used data size of 10 GB. They’re billed based on the used portion of the disk. Snapshots can be used to create new managed disks when a VM is rebuilt. Snapshots exist independently of their source disks. A managed snapshot is a full, read-only copy of a managed disk. In development and test environments, snapshots provide a quick and simple option for backing up VMs that use managed disks. The recovery plan feature is integrated with Azure automation runbooks. Create recovery plans to orchestrate failover and failback of the entire application running on multiple VMs. You can run disaster-recovery drills with on-demand test failovers, without affecting your production workloads or ongoing replication. You can replicate to an Azure region of your choice, since recovery isn’t restricted to paired regions. You can configure Azure Site Recovery for your VMs so that your applications are recoverable in matter of minutes with a single click. These scenarios may include widespread service interruptions or regional outages caused by natural disasters. Azure Site RecoveryĪzure Site Recovery protects your VMs from a major disaster scenario. When you restore from a recovery point, you can restore entire VM or specific files. Azure Backup creates recovery points that are stored in geo-redundant recovery vaults. Azure Backup supports application-consistent backups for both Windows and Linux VMs. You’ll use Azure Backup for most use-cases involving backup operations on Azure VMs running production workloads. There are several backup options available for virtual machines (VMs), depending on your use-case. ![]() You can protect your data by taking backups at regular intervals. In this article I only talk about different backup options Azure Virtual Machine (IaaS). ![]() While hosting our application on IaaS we are more prone to failures since we are responsible for managing the infrastructure as well. Cloud vendors provide us different options such as IaaS, PaaS or SaaS to host our application. This also means keeping data secure and resilient to failures should be one of the top priority. In today’s world where data is the new oil and almost everything revolves around data one way or another.
