5 Common Mistakes while Backing up VM and How to Avoid them

Virtual machines are a great way to test software and new operating systems. They can also help you when you need to quickly create a server. However, if they are not backed up properly, they can be lost forever.

In this blog post, we will discuss 5 common mistakes that people make while backing up virtual machines and how to avoid them.

  7 Best Practices for VM Backup You Must Know 

Backing Up a Virtual Machine

Backing up a virtual machine is not as simple as copying the files to another location. You need to take into account the fact that a virtual machine is made up of many files and each file has a specific purpose.

There are many ways to back up a virtual machine. You can use tools that come with your hypervisor, or you can use third-party tools. Some people even choose to manually copy their VM files to an external hard drive.

One of the best VM backup tools is Altaro VM Backup. It is a powerful and easy-to-use backup solution for VMware and Hyper-V. It’s a fast, cost-effective, and high-performance backup and replication tool that comes with an amazing user interface. The application is simple to manage and provides detailed reports on your backup process. It also allows you to set up granular recovery points, so you can restore your VM to a specific point in time if necessary. You don’t require any special training to use this tool, and it’s very affordable.

While backing up a VM is important, there are some common mistakes that people make. Let’s take a look at the top five mistakes

Common Mistakes While Backing Up a VM

Mistake #1: Not Backing Up Regularly

One of the most common mistakes people make is not backing up their VM regularly. Just like any other type of data, VMs need to be backed up on a regular basis. The frequency of the backups will depend on how often your VM is used and how important the data is.

If you only use your VM for testing purposes, you can get away with backing it up once a week. However, if you are using your VM for production purposes, you should be backing it up at least once a day. The best way to ensure that your VM is being backed up regularly is to set up a backup schedule. This way, you will never have to worry about forgetting to back up your VM.


Mistake #2: Backing Up through a Guest OS

Another common mistake people make is backing up their VM through the guest operating system. This is not an effective way to back up a VM because it does not include the entire VM. When you back up through the guest OS, you are only backing up the files that are located on the virtual hard drive.

This means that any files that are located on the virtual machine’s memory or on any other type of storage will not be backed up. In order to effectively back up a VM, you need to use a backup tool that can access all of the VM’s files.

VMs cannot be backed up using traditional backup techniques that employ guest OS agents. While this works, it is inefficient because the virtualization layer sits between the guest OS layer and the physical hardware layer. The guest OS no longer has direct access to real hardware where the data is encoded, therefore a backup agent on the guest OS must pass through the virtualization layer to reach the VM data.


Mistake #3: Relying on VM Snapshots as a Primary Backup

Another common mistake is relying on VM snapshots as the primary backup. VM snapshots are a great way to quickly create a copy of your VM. However, they should not be used as the sole method of backing up your VM.

In order to effectively back up a VM, you need to use a backup tool that backups your VM fully as well as making efficient use of the storage available.


Mistake #4: Not Scheduling your Backup Operations

One of the most important aspects of backing up a VM is scheduling your backup operations. Without a schedule, it can be easy to forget to back up your VM.

When you are creating a backup schedule, you need to take into account the frequency of the backups as well as when the backups will be taken.

It’s important to choose a time when the VM will be unused so that the backup process doesn’t interfere with your work.


Mistake #5: Backing up to a Single Location

When you are backing up your VM, you should always back up to more than one location. This is because there is always the possibility of data loss.

If you only back up to one location and that location experiences a data loss, you will lose all of your backups.

However, if you back up to multiple locations, you can be sure that at least one of your backups will be safe.


How to Avoid Mistakes while Backing Up VM?

Now that we’ve gone over some of the most common mistakes people make while backing up their VM, let’s go over how you can avoid them.

  • The best way to avoid these mistakes is to use a backup tool that is designed specifically for VMs. With the right backup tool, you can be sure that your VM is being backed up correctly and efficiently. There are many different backup tools available, so it’s important to choose one that fits your needs.
  • Another important consideration is the frequency of the backups. If you are using your VM for critical applications, you will want to back up more often than if you are using it for non-critical applications.
  • Finally, you should make sure that the backup tool has a scheduling feature so that you can automate your backup operations.
