If the entire VM was deleted, snapshots alone would not be sufficient unless the snapshot files (.vmdk) are intact and you have a way to recreate the VM using those files.

    3. Datastore Browsing

    If the VM was deleted from the inventory but its files remain on the datastore, you can recover it by:

    • Browsing the datastore through the vSphere Client.
    • Locating the VM’s folder and its primary configuration file (.vmx).
    • Right-clicking the .vmx file and selecting “Register VM.” This will add the VM back to the inventory, allowing you to power it on.

    4. Using Recovery Tools

    For scenarios where the VM has been deleted from both the inventory and the datastore, specialized recovery tools like DiskInternals VMFS Recovery can be used to attempt recovery of the VM’s files from the VMFS (VMware File System) datastore. This method requires:

    • Scanning the datastore with the recovery tool.
    • Identifying recoverable VM files.
    • Restoring these files to a safe location.
    • Re-registering the VM in the inventory if the critical files (such as .vmx and .vmdk) are successfully recovered.

    5. Professional Data Recovery Services

    If other methods fail or if the data is critical, professional data recovery services might be able to recover the deleted VM. These services can often recover data even in challenging situations, such as hardware failure or complex data loss scenarios.

  • How to reset VM in VMware?

    VMware reset virtual machine refers to performing a hard reset of the virtual machine, similar to pressing the reset button on a physical computer.
