What Is the VMDK File?
VMware Virtual Machine Disk is a format specification for virtual machine (VM) disk image files.
A file with the .vmdk file extension is essentially a complete and self-contained virtual machine.

VMDK allows the cloning of physical drives for virtualization and off-site backup of virtual machines.
But it is now an open-source file format that can be used by different non-VMware virtualization platforms.
VMDK files can be dynamic or fixed.
Fixed VMDKs are allocated a fixed large size from the start to accommodate size changes as VM usage increases.
In contrast, a dynamic disk scales with the size of the files in the guest operating system.
Tip: VMDK files are easily damaged, resulting in the loss of virtual machine data.
Therefore, you better provide security insurance for your virtual machines.
you’re free to back up the VMDK files or even all the VMware data.
To back up your VMDK files, you’re able to try theprofessional backup program MiniTool ShadowMkaer.
With it, it’s possible for you to easily back up and restore your files with simple steps.

VDI is compatible with VHD and VMDK, which means that Oracle VirtualBox can run images with both extensions.
It uses Oracle Virtual Media Manager to create and replicate VDI, VHD/VHDX, and VMDK virtual hard disks.
There are many free file-to-image conversion tools available.
VMDK allows incremental backups of data changes since the last backup.
VDI and VHD do not provide this functionality.
VMDK is a much faster virtual disk format than VDI and VHD (and VHDX).
Additionally, it includes live migration functionality to make it easier to move a VM to another server.
It also provides snapshots, continuously protects data, and uses high-performance SAN block storage.
Finally, users can recreate and reboot the VM using the backed-up VMDK file.
