What is Snapshot
A snapshot in VMware is essentially a copy of the virtual machine's disk file (VMDK) at a given point in time. It preserves the state and data of a virtual machine at a specific point in time.
When you take a snapshot of a VM, a file is created that captures the state of the virtual machine settings, along with the state of all the virtual disks attached to the VM. It provides a change log for the virtual disk and is used to restore a VM to a particular point in time when a failure or system error occurs.
The snapshot feature in VMware is a great tool for system administrators as it provides a fast and easy way to revert the virtual machine to a previous state in case of system malfunction or software failure. This makes it a handy tool for testing new software, updates, or configurations, as you can simply roll back to the previous state if something goes wrong.
How to Take a Snapshot and Revert It
1. In VMware Workstation, select VM, choose the Snapshot option, and proceed to take a Snapshot.
2. Input a name for your snapshot. While you can also add a description, this step is optional. Once you've finished entering the details, click on Take Snapshot and wait for the process to complete.
3. After the snapshot process is complete, you are presented with a snapshot option that allows you to revert to the snapshot state. Alternatively, you can create multiple snapshots and choose to revert back to a specific point based on any of these snapshots.
Why Snapshot is Not Backup
Please note that snapshots are not meant to be a full-time backup solution, as they can take up a considerable amount of storage space, and maintaining too many old snapshots can lead to degraded VM performance.
Additionally, VMware snapshots do not protect against virtual machine deletions or data center-wide incidents.
What's worse, If a VM is running from a snapshot and the snapshot becomes corrupted, it can potentially lead to data loss or corruption of the virtual machine.

1. What is the difference between backup and snapshots in VMware?
The key difference between a backup and a snapshot in VMware lies in their purpose and functionality. A snapshot captures the state of a virtual machine at a specific point in time, including its settings and the state of its virtual disks. It's primarily used for short-term solutions, such as troubleshooting or testing system updates.
On the other hand, a backup is a complete copy of the entire virtual machine, including all data and configurations. It provides a long-term solution for data recovery in case of data loss or corruption, system failure, or disaster recovery. Unlike snapshots, backups do not impact the performance of the virtual machine and can be stored offsite or on different media for added protection.
2. Is a snapshot a full backup?
Snapshot copies the state of a system at a certain point in time, preserving a virtual picture of your server's file system and settings. Unlike a backup, which performs a full copy of your data, a snapshot only copies the settings and metadata required to restore your data in the event of a disruption.
3. How long does a VMware snapshot take?
The time required to create a snapshot depends on the amount of data involved and the server load at the time. On average, the creation of a minimal snapshot typically takes between 30 to 40 seconds.
