VMware provides Cloning and Snapshots as powerful features to manage Virtual Machines (VMs).
- Cloning: Creates an identical copy of a VM for backup or testing.
- Snapshots: Saves the current state of a VM so you can restore it later if needed.
1. Cloning a Virtual Machine
A clone is an exact copy of a VM that can be used independently.
Types of Clones in VMware
Clone Type | Description | Use Case |
---|---|---|
Full Clone | Creates a complete copy of the VM, including all files | Best for backups & independent VM use |
Linked Clone | Shares disk with the original VM to save storage space | Useful for testing and development |
Steps to Clone a VM in VMware Workstation
- Power off the VM you want to clone.
- Right-click the VM in VMware Workstation.
- Click “Manage” > “Clone”.
- Choose “Create a full clone” or “Create a linked clone”.
- Name the clone and select the location to store it.
- Click Finish.
🚀 Now you have an exact copy of your original VM!
2. Taking a Snapshot of a Virtual Machine
A snapshot allows you to save a VM’s current state and revert to it later if needed.
When to Use Snapshots?
✅ Before making major software updates.
✅ Before testing new applications.
✅ To prevent data loss in case of errors.
Steps to Take a Snapshot
- Power on the VM.
- Click “VM” > “Snapshots” > “Take Snapshot”.
- Name the snapshot (e.g., “Before Software Update”).
- Add a description (optional).
- Click OK.
Restoring a Snapshot
- Click “VM” > “Snapshots” > “Snapshot Manager”.
- Select the snapshot you want to restore.
- Click “Go To” to revert the VM.
Deleting a Snapshot
- Open Snapshot Manager.
- Select the snapshot.
- Click “Delete” to free up disk space.
3. Differences Between Cloning & Snapshots
Feature | Cloning | Snapshots |
---|---|---|
Creates a copy? | ✅ Yes | ❌ No (only saves state) |
Storage usage | High (Full Clone) | Low |
Performance impact | None | Can slow down the VM |
Use case | Backup, testing | Quick recovery |
4. Best Practices
✅ Use full clones for long-term VMs.
✅ Use snapshots sparingly (too many can slow down VM performance).
✅ Delete old snapshots to save disk space.
✅ Always take a snapshot before making major changes.
