The term "snapshot" can have different meanings depending on the context, but generally, it refers to an instant image or copy of a system, state, or dataset at a specific point in time. Some examples include: 1. In computer storage and database management, a snapshot is a copy of a system or database's state at a particular moment. This copy can be used to revert to a previous state or for data analysis and backup purposes. 2. In photography, a snapshot refers to a quick photograph, often informal or capturing everyday moments. 3. In version control systems (such as Git), a snapshot denotes the complete state of a project at a specific time point. 4. In virtualization technology, a snapshot is the entire state of a virtual machine at a particular moment, including the operating system, applications, and data. It can be used for backup or rolling back to a previous state. 5. In financial markets, a snapshot might refer to the status of stock markets, exchange rates, or other financial indicators at a specific time. Overall, a "snapshot" provides a record or capture of a situation at a given point in time, which can be used for subsequent analysis, comparison, or restoration.
In the context of computer systems, a snapshot is an "image" that represents the state of a system at a specific point in time. Snapshots are used to revert a system back to the condition it was in when the snapshot was taken, protecting it from data corruption or hardware failures.
How do snapshots work?
When a snapshot is created, the underlying system creates a differencing disk on top of the original virtual hard disk. This ensures that all data written afterward is directed to the differencing disk, leaving the contents of the original virtual hard disk unchanged.
As the file system continues to run, multiple snapshots are created at different points in time, providing branches for the file system. This allows for the recovery of recently modified data or the restoration of the system state.
What is Snapshot Backup? Snapshot backup is a data protection method that captures the state of a system or data at a specific point in time. In a storage system, a snapshot is an instantaneous and consistent copy of the original data, typically generated by a file system or storage array. Unlike a full backup, a snapshot does not require copying the entire dataset; instead, it records the changes made to the data since the last backup. This makes snapshot backups fast and resource-efficient. When data needs to be restored, a snapshot can be used to revert to the state of the system or data as it was at the time the snapshot was taken. Snapshot backups are commonly used to guard against accidental data loss, simplify the recovery process, and provide multiple versions of data at different points in time. They are particularly prevalent in virtualized environments, database management, and cloud storage services.
Snapshot backup, also referred to as image backup, is a type of backup copy. It does not store data but instead functions by defining the location and pattern of data storage.
When do people need snapshot backups?
There are many instances where you might need to take a snapshot of your computer, such as when your system won't boot, there's been a virus attack that has corrupted your system, or you accidentally deleted an important file. Snapshots ensure that your system or files can be restored to their pre-fault state, so it's important to know how to take one.

Frequently Asked Questions
Is a snapshot backup a full backup?
No, it doesn't. A snapshot backup only provides the data of a system's state at a specific point in time. Furthermore, a snapshot in itself is not a backup; it's an essential component of a system backup process. Hence, a snapshot backup is not a Full Backup.
What types of snapshots are there?
There are four types of snapshots.
Copy-on-write: Metadata indicating which blocks have changed since the file was created.
Write-through: Write a snapshot only when creating a new block.
Continuous data protection: Snapshots are created on the fly and updated every time the source copy changes.
Cloning/Mirroring/Copying: Cloning or mirroring is an exact copy of a storage unit, while copying is a form of data protection.
