What is VMware ESXi?

VMware ESXi is software that lets you run several virtual machines on one physical server. It helps manage virtual environments efficiently and flexibly. The data stored in ESXi—like virtual machine files, snapshots, and settings is very important for businesses. If you lose this data, it can cause downtime, slow work, and even financial losses.

VMware ESXi is part of VMware vSphere and is designed for virtualization at the server level. It uses a VMFS (Virtual Machine File System) datastore to store all VM-related files, including VMDK (virtual disks) and VMX (configuration files). This datastore is crucial because it holds all the business-critical virtual workloads.

Why Data Recovery from VMware ESXi Is Crucial

Data loss in VMware ESXi can happen due to multiple reasons, and its impact can be severe. If you identify the common causes and consequences of data loss, it will help you select the right recovery method.

Common Causes of Data Loss in ESXi

• Accidental Deletion: Mistakenly deleting virtual machines or snapshots.
• Hardware Failure: Storage devices or RAID failures affecting VMFS datastores.
• Datastore Corruption: Improper shutdowns, software errors, or power outages can corrupt VMFS.
• Malware or Ransomware: Security attacks targeting VMs or their data.

Impact of Data Loss on Businesses

Data loss can result in operational downtime, decreased productivity, and financial loss. Even minor VM data loss can halt critical business processes, making quick and effective recovery essential.

Manual Recovery Methods to Recover Data from VMware ESXi

Manual recovery methods are ways that administrators can use to recover data. These ESXi file recovery methods usually depend on existing backups, snapshots, or direct access to the datastore. Although they are free and can work well in some cases, they often take more time and require technical knowledge.

1. Restore VMware ESXi Data from Backup 

Restoring from a backup is the most common manual recovery method. If you have regular backups of your virtual machines or datastores, you can easily recover lost or corrupted data.

1. Open your backup solution, such as vSphere Data Protection, Veeam, or any other ESXi-compatible software.
2. Find the VM or datastore snapshot you want to restore.
3. Select the VM or data and start the restore process.
4. After restoration, verify the VM by starting it in ESXi or the vSphere Client.

2. VMware Snapshot Recovery

Snapshots capture the state of a VM at a specific point in time. They allow you to restore the VM to how it was when the snapshot was taken.

1. Open the vSphere Client and find the VM that needs recovery.
2. Go to the Snapshots section of the VM.
3. Choose the snapshot you want to restore.
4. Click Revert or Restore to recover data from VMware ESXi to that snapshot.

3. Datastore File Recovery to Recover Deleted Files from ESXi

Datastore file recovery involves accessing the VMFS datastore directly to retrieve VM files like VMDK (virtual disk) and VMX (configuration files). This method is technical but can help when backups or snapshots are missing.

1. Connect to your ESXi host using SSH or the vSphere Client.
2. Navigate to the VMFS datastore where your VM files are stored.
3. Find the VMDK and VMX files for the affected VM.
4. Copy the files to a safe location, such as another datastore or external storage.
5. Register the VM in ESXi by right-clicking Register VM and selecting the recovered VMX file.

4. Reverting to vCenter Server Backups

If your ESXi host is managed via vCenter Server, you can restore VMs using vCenter backups. This includes VM configurations, inventory, and some datastore files.

1. Open the vCenter Server backup solution.
2. Select the backup date and the VM you want to restore.
3. Restore the VM and its configuration to the ESXi host.
4. Check the VM by powering it on.

Drawbacks of Manual Recovery Methods

Even though manual recovery can work, it has some drawbacks:

• It works only if backups, snapshots, or datastore files exist.
• Cannot recover corrupted or permanently deleted data without prior backups.
• Moreover, there is a high risk of human error during file handling or SSH commands.
• These approaches are time-consuming for large or multiple VMs.
• Along with that, it is not suitable for recovering many VMs at once.
• Apart from that, it requires technical expertise to perform correctly.

Because of these limitations, using automated VMware ESXi recovery tools is often faster, safer, and more reliable, especially for deleted or corrupted data.
