👉In summary, the commonly used VMware VM backup solutions include:
The last 4 backup solution for VMware are self-contained (both in ESXi and Workstation), but users who are not proficient in virtual machines may not be able to tell the difference and applicable scenarios between them. So I'd like to make an intuitive comparison and help you to pick the one best suitted to your case.

|Batch operation||Yes||No||Use PowerCLI||Use PowerCLI||Use PowerCLI|
|Backup schedule||Yes||No||No||Use vCenter||Use vCenter|
So all in all, if you are computer savvy and familiar with VMware's tools, you can use the built-in backup solutions to achieve many data protection goals. But if you want a long-lasting VMware backup solution without spending too much time on operation and management, then a reliable VM backup software is a more effective option.
In the following, I will introduce these backup solutions in detail with screenshots. The steps are based on VMware ESXi, if you are using Workstation, please turn to: VMware Workstation backup solutions
Professional VM Backup software captures point-in-time state of the entire VMs without resource contention, and creates independent backups that allow for fast and complete VM recovery.
Besides the basic functionality, backup tools nowadays usually contain more useful features to relieve your burden, such as scheduled backup, centralized management, full or incremental option, etc. The only problem is that many professional VMware backup software is expensive and not always suitable for all users.
Therefore, I'd like to present you a free VMware backup software - AOMEI Cyber Backup. It includes the benefits I mentioned above, or to be more specific:
Agentless Backup: Create complete and independent image-level backup for VMware ESXi VMs.
Support Free ESXi: Support both paid and free versions of VMware ESXi.
Multiple Storage Destinations: Back up to local folders, network shared folders and NAS shared folders (folders shared via the SMB protocol).
Automated Execution: Automate virtual machine protection and notified by email.
Restore from Any Point: Restore entire VM from any backed up restore points.
AOMEI Cyber Backup supports VMware ESXi 6.0 and later versions. Here I will demonstrate how to quickly schedule an automatic backup task of multiple ESXi VMs. You can click the following button to download the freeware:
*You can choose to install this VM backup software on either Windows or Linux system.
How to create auto VM backup with VMware backup software:
1. Bind Devices: Launch AOMEI Cyber Backup web client, navigate to Source Device > VMware > + Add VMware Device to add vCenter or Standalone ESXi host as the source device. And then click … > Bind Device.
2. Create Backup Task: Navigate to Backup Task > + Create New Task, and then set it up according to your needs.
- Device: cover multiple VMs on the host in one backup task.
- Target: selecting to back up to a local path, or to a network path. Used paths will be saved in Favorite Storage for handy selection.
- Schedule: choosing to perform full, differential or incremental backup, and automate execution daily, weekly or monthly according to the frequency you specified.
3. Start Backup: Click Start Backup and 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, editing and restoring.
Manually downloading the VM files is probably the most direct one of VMware free backup solutions. By re-deploy (or “Open” on Workstation) the downloaded virtual disk files (.vmdk) and the configuration files (.vmx), you can directly create an instantly usable copy of the VM.
How to manually download the VM files:
1. Access ESXi Web Client, navigate to Storage in the left inventory, and click Datastore browser on the toolbar.
2. Go to the folder of the virtual machine you want to back up. Select the .vmdk files and .vmx files and click Download on toolbar to download them to a local path.
3. Close Datastore browser window, and you can see the progress in Recent tasks.
By exporting VM to OVF/OVA templates, you will gain faster downloads since the OVF files are compressed, and supports exchange of virtual appliances across products and platforms.
How to export the ESXi VM to OVF:
1. Access ESXi Web Client, commit all snapshots and power off the virtual machine you want to back up.
2. Navigate to Virtual Machines page, right-click on the virtual machine you want to back up and select Export. Click OK in the pop-up window to continue.
3. Click Save File option twice to download the .ovf file and .vmdk file. Click OK to close the window. You can see the progress in Recent tasks.
When it’s done, you can click Download button on toolbar to find where these files are stored.
VM cloning is the process of creating an exact copy of a virtual machine, including the virtual hardware and guest operating system. There are 2 kinds of clone - a full clone takes longer time, while a linked clone takes shorter, but the cloned VM may be unusable if the parent VM fails.
Cloning may be different from other backup solutions for VMware whose main focus is on data protection, but it's a convenient way to migrate virtual machines, or create multiple same VMs.
How to clone VMware ESXi VM using vCenter:
1. Access vCenter Client, right-click on the VM name and select Clone > Clone to Virtual Machine.
Except for this option, you can also select Clone to Template… or Clone to Template in Library.
2. Provide a Name and select a destination datastore folder location for the new VM. Then click Next.
3. Select a destination host for the new VM, click Next.
4. On select storage page, Select virtual disk format as Same format as source, and VM Storage Policy as Keep existing VM storage policies. And then select a datastore location to store the VM files. Click Next to continue.
5. Select further clone options, you can customize the operating system, the VM’s hardware, or select whether to power on the VM after creation. Click Next.
6. Review your selections and click Finish to start. You can see the progress in Recent Tasks.
A VMware snapshot is an image that captures the complete state and data of a virtual machine at a specific point in time. The state includes the power state of the VM (powered-on, powered-off, or suspended), and the data includes all the files that make up the VM (disk, memory, and other devices). It is a quick and efficient way to roll back VM to a specific point in time, just like the undo function.
How to take a snapshot of the ESXi VM:
1. Launch vSphere Web Client. Right-click on the VM name in the inventory and select Snapshots > Take Snapshot…
2. In the pop-up window, provide a Name and optionally a Description for the snapshot. You can Edit them later in Snapshot Manager.
3. There are 2 options to check:
- Snapshot the virtual machine’s memory: record the VM’s memory, allowing you to roll back the VM to the exact running state when the snapshot was taken, but takes longer. If you leave this option unchecked, then the VM will be powered-off after you roll back.
- Quiesce guest file system (needs VMware tools installed): pause the state of the processes that are running, or may modify the information stored on disk when the snapshot was taken, to guarantee the consistency. Quiescing and Memory snapshots are mutually exclusive.
4. Click OK to take the snapshot. You can see the progress in Recent Tasks.
Backup is one of the most important jobs for VM users, and choosing a suitable way can maintain the business continuity and improve efficiency.
In this article I presented 5 VMware backup solutions, 4 of them are built-in features. They may be enough for Workstation VMs. But if you want a comprehensive and cost-effective software to backup VMware ESXi VMs, I recommend you a professional backup tool, AOMEI Cyber Backup. Besides backup and restore, it also allows one administrator to create sub-accounts with limited privileges for efficient collaboration.
