Brief introduction to VM cloud backup
In terms of disaster recovery, offsite backup is certainly an additional insurance for data protection. No exception for virtual machines.
Many system administrators adhere to a golden 3-2-1 backup rule: keep 3 copies of data stored on 2 types of media, and at least 1 offsite. As a result, VM cloud backup is gaining popularity in the IT industry.
Backing up VMs to the cloud effectively protects the backups from disasters, and allows unlimited restore at any time and location. Some cloud computing platforms, such like Microsoft Azure, even capable of creating and running VMs, at a considerable price, of course. If you want to reduce costs, you can also backup your VMs with affordable software and store them in the cloud.
In this article, I will introduce the steps of Microsoft Azure cloud VM backup as an example.
How to backup VM to cloud via Microsoft Azure Backup Server (MABS)
1. Create a Recovery Service vault, configure On-Premises workload and select Hyper-V Virtual Machines as desired source.
2. Install Microsoft Azure Backup Server (MABS) and setup according to the wizard.
3. Configure the MABS storage. Here are the Microsoft’s official storage capacity guidelines:
- Average virtual machine size - 100 GB
- Number of virtual machines per MABS server - 800
- Total size of 800 VMs - 80 TB
- Required space for backup storage - 80 TB
Set up the MABS protection agent on the Hyper-V server or Hyper-V cluster nodes.
4. In the MABS Administrator console, select Protection > Create protection group to open the Create New Protection Group wizard.
5. On the Select group members page, select the VMs you want to backup, and enable colocation to locate data from different protection groups on the same storage.
6. On Select data protection method page, provide a Protection group name, check I want short-term protection using option and select Disk, and check I want online protection.
7. On Select short-term goals page, specify a Retention range, and how often the incremental backups should run, or MABS will run express full backup and creates recovery points according to the express schedule.
8. On Choose replica creation method page, select to Automatically or Manually create a replica of data.
9. On Consistency check options page, select to Run a consistency check if a replica becomes inconsistent, or Run a daily consistency check according to the following schedule.
10. On Specify online backup schedule page, define the schedule you want to create a backup copy.
11. On Specify online retention policy page, specify the retention policy which DPM will use to generate your protection plan.
12. On Summary page, review all the settings and click Create Group. After you create the protection group, initial replication of the data occurs in accordance with the method you selected. After initial replication, each backup takes place in line with the protection group settings.

An easier alternative to backup VMs and store in the cloud
As you can see, the process of backing up VMs to Azure with Azure Server is very complex. If you want to reduce costs, you can also backup VMs with affordable third-party software.
Here I recommend you an easier alternative, AOMEI Cyber Backup, which allow you to remotely backup VMs to network locations with 3 simple steps. In addition, it has the following benefits.
✦ Supported versions: centrally manage VMs on Hyper-V in Windows 8/8.1/10/11, Windows Server/Microsoft Hyper-V Server 2012 R2 and later versions, as well as VMware ESXi 6.0 and later versions.
✦ Affordable Pricing: reasonable charges only base on the number of bound devices, regardless of how many VMs are on the host.
✦ Offsite Restore: capable of restoring backups to new VMs on original or another datastore, host.
✦ Role Assignment: allows one administrator to create sub-accounts with limited privileges, effectively avoid errors caused by others’ mis-operations.
Next, I will demonstrate how to create an automatic backup task of multiple Hyper-V VMs. You can click the following button to start a free trial.
3 simple steps to backup multiple Hyper-V VMs
1. Bind Devices: Access to AOMEI Cyber Backup web client, navigate to Source Device > Hyper-V > + Add Hyper-V to add a host. And then click … > Bind Device.
2. Create Backup Task: Navigate to Backup Task > + Create New Task, and then provide Task Name, Backup Type, Device, Target, Schedule, and Cleanup.
- Device: you can cover multiple, or even all VMs on the host in one backup task.
- Target: you can select to back up to a local path, or to a network path for safer storage.
- Schedule: choose to perform full or incremental backup, and automate execution daily, weekly or monthly according to the frequency you specified.
- Cleanup: specify a retention period, and the old backup files that exceed the period will be automatically deleted.
3. Start Backup: Click Start Backup and you can select Add the schedule and start backup now, or Add the schedule only.
Created backup tasks will be listed and monitored separately, for progress checking, schedule changing and restoring.
Storing VM backups to an offsite location can further protect the VM data from accidental disasters.
In this article, I showed how to perform VM cloud backup via Microsoft Azure Backup Server, and introduced an easier alternative to backup VMs to a network path, AOMEI Cyber Backup. Except for Microsoft Hyper-V, It can also backup VMware ESXi VMs automatically.
