What Is VM Backup – How to Backup Virtual Machines

The backup of the virtual machine, i.e., VM backup, makes a backup of virtual machines (VMs) operating in the environment of the enterprise. 

VMs typically work as guests on supervisors that emulate a computer system and allow multiple VMs to share a physical host hardware system. VM backup optimization software utilizes its knowledge of the virtualized environment and completes backups more efficiently without affecting other workplaces.

It is also essential to back up VM configuration information, running as clusters and permissions, to facilitate host recovery if necessary.

Why do we need to back up a virtual machine?

Faster recovery from disasters

With a faster disaster recovery solution, your business can recover faster from data loss or unexpected hardware failure. Virtual machines include this feature to create regular backups of their day-to-day operations. The virtual machine backup operation will backup data with the assistance of a backup agent.

Centralized management

Virtual machines consolidate IT management into a single console. You no longer need to operate or operate multiple physical devices. Incremental backups can restore VMware virtual machines and provide virtual machines backups to centralize the management.

Operational flexibility

With VMs, your IT experts no longer have to handle multiple displays and systems. You can operate multiple applications simultaneously with virtual machines.

Minimized overhead costs

VMs also require power utilization and licensing, but resource consumption is reduced for these machines. For that reason, there is a reduction in overhead costs for virtual machines.

Virtual machine backup software

To ensure complete data protection, regular backups must be created from the beginning. Backups for deployments of oversized virtual machines can take up more storage space and waste resources.

It is recommended to install backup software that runs faster and requires less storage space and bandwidth to improve the backup process. The best way to enhance VMware backups is to list or select only the critical information about your business.

Hence, clean up any unwanted or zombie virtual machines. It may take a lot of time and effort, but it will help pay off for better results and more efficient backup solutions.

VMware virtual machines backup process

A virtual machine backup is a VM data protection solution that performs similar functions to traditional backup solutions used by physical servers. VMware VMs contain VMware tools that grant data protection on the guest operating system.

VMware Virtual Machine Backup applications can perform a full backup of all files in the VM, Permanent Backup, or Differential Backup. VM backup software should run frequently and periodically to protect VM files, configurations, and constantly changing data.

State-of-the-art VMware virtual machine backup software will take advantage of enhancements available through Hypervisor that enable faster backups with less impact on the virtual machine.

VM backup concepts

The following are essential concepts for understanding VM backup procedures:

  • Differential backup
  • File-level backup
  • Full backup
  • Full VM backup
  • Image-level backup
  • Incremental backup
  • Quiescing

VM data recovery points

Having coming the time to restore a VM backup, there are two main approaches:

1. Full image-based backup: you can turn off the VM and restart it based on your image backup. It is often the most straightforward and fastest method of recovery.

2. Granular recovery: in some cases, you may want to restore only specific files instead of the entire VM. See our VMware File Recovery article to determine how easily this can be done with a third-party backup. If you work with Hyper-V VMs, see this article on Hyper-V File Recovery.


Today, most business networks use virtual machines because of their flexibility and cost-effectiveness. Maintaining a virtual machine in an organization can save costs, increase productivity, and facilitate security.

There are numerous reasons why companies assume virtual machines are a great resource. Eventually, the use of virtual machines has increased. Thus, it has become crucial to install or set up the software to assist in the management and monitoring of these virtual machines.

With the proper VMware backup, you can make an immediate backup to save complete information about the virtual machine or information that has changed since the previous backup. It also offers data security and allows for quick disaster recovery with proper backups.

Recognize that VMs may stop working without appropriate maintenance or start having problems after some time. As a result, the business may suffer data damage or loss, and therefore VM backup frequency is the right thing to do.
