Data recovery is a term that IT admins and pro PC users frequently use. It refers to the process of retrieving lost, damaged, or corrupted data from a computer or other storage device. This process is critical in any setting where data is important, whether it's for personal or business use. Virtual machines are no exception to this rule.
Virtual machines (VMs) are virtualized operating systems that run on a physical machine, and they can be used for a variety of purposes, such as software development, testing, and hosting applications. Like any other computer, VMs are susceptible to data loss or corruption, and it's essential to have a backup and recovery plan in place to minimize the risk of data loss.
One of the most common reasons for data recovery is accidental deletion of files or entire VMs. This can happen due to user error, software bugs, or hardware failures. Files can become corrupted due to software errors, hardware issues, or power outages. Malware or virus attacks can also cause data loss or corruption by deleting files or altering their contents. Hardware failures such as disk crashes, controller failures, or power surges can cause data loss or corruption. Operating system issues such as driver conflicts, system crashes, or software updates can also cause data loss or corruption.
When any of these situations occur, it may be necessary to recover data from a VMware disk to restore lost or damaged files. Fortunately, VMs can be restored either to their original location or to another one. The original hypervisor is used to restore virtual machines by default, and the backup proxy is used. A virtual machine can be restored to vCloud if the hypervisor is set up to support it.
To restore a VM, the restoration procedure may be started from the VM groups page, the Virtual machines page, or the detail page for a particular VM. You have the option to restore the whole VM, employ live recovery, or carry out a live mount action when you start a restoration process for a specific VM from the VM groups page or the Virtual machines page.

The Live Recovery function can also be used to swiftly restore a failing virtual machine to production or to confirm that a backup can be used in a disaster recovery situation. This functionality enables the actions required by the VM, restores data from the backup as needed, and finishes the entire restore as soon as resources permit, without changing the backup.
If you need to recover VMware virtual machines from backup files (VMDK), the process is straightforward. You need to access the ESXi Web Client, go to the Storage page, and click on “Datastore browser” on the toolbar. In the new window, click “Create directory” and create a new folder for the new virtual machine. Import the VMDK and VMX files into this new folder, go to the Virtual Machines page, and click on Create/Register VM on the toolbar. On the “Select creation type” page, choose “Register an existing virtual machine,” and select the VMX file.
In summary, having a backup and recovery plan for your virtual machines is essential to minimize the risk of data loss and ensure that critical data can be restored quickly and easily. With the right tools and procedures, you can restore your VMs to their original location or another one, employ live recovery, or carry out a live mount action when you start a restoration process.
