This article outlines how to back up virtual machines while running without interrupting them.
Setting up a backup task in BackupChain with incremental and differential deduplication takes just two minutes, and is outlined below.
BackupChain offers live virtual machine backup for various platforms:
- Backup virtual machines running on Hyper-V
- Backup virtual machines running on VMware Workstation, VMware Server & VMware Player
- Backup virtual machines running on VirtualBox

Step 1: Create a New Task
Create a new task and select the type of virtualization platform you are using. In our example, we’ll use VMware. For a walkthrough for Hyper-V Servers, click here. The steps for Microsoft Virtual Server are the same as shown in this example walkthrough.
Step 2: Select Folder Containing VM Files
Create a new task and select the folder containing your image files (.VHDX, .AVHDX, .VHD, .AVHD, .VMDK, etc.) Hint: click on images to zoom in.
Step 3: Select a Target Folder
Proceed with the New Task Wizard to the point where you specify the target.
You can either store your backup locally, on an external drive (USB), on the network via a network share, or to an FTP/FTPS location. In this example, we chose a network share target on another NAS server:
Once saved, the setting should appear under the Backup Target tab:
Step 4: Enable Compression and Encryption
Because VMs generally compress well, it makes sense to turn on ZIP compression.
The Delta Compression (deduplication) algorithm will not compress the inner blocks of files unless this setting is checked. Note: the delta algorithm will only save compressed blocks
if they actually compress to a smaller block length than the original. This feature helps you save even more space and restore time.
Turning on encryption and entering a password will protect your files using military strength encryption (256 bit AES):
Step 5 (optional): Set Schedule Options
Now you’re ready to start the task. If you want to schedule it to run repeatedly, you can switch to Continuous, Daily, Weekly, Monthly, or other scheduling modes.
The following illustrates a sample configuration to run on selected months, on the first Sunday.
Congratulations: Your Backup is Complete!
We hope this walkthrough illustrated how simple it is to create an automatic task using BackupChain. Because this tool saves you storage space and time, it is well suited to
serve as a remote backup software for your servers.
The file-based procedure shown above in this article is the same for all host platforms.
