For a computer system, a snapshot is an "image" that can represent the state of the system at a characteristic point in time. When you want to restore the system, your snapshot will be used to restore the system to the state it was in when the snapshot was taken, thus protecting the computer from data corruption or hardware failure.
How Do Snapshots Work?
When the snapshot is created, the underlying system will create a differential disk that is bounded to the original virtual hard disk. This method can ensure that all data written in the future is directed to the differential disk, thus keeping 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 and provide multiple branches for the file system. Because of this, snapshots can help restore recently modified data or restore the system state.
Snapshot backup can also be referred to as image backup, it is a type of backup copy. It does not store data but plays its role by defining the location and mode of data storage.
When Do People Need Snapshot Backup?
In the process of using the computer, you will inevitably encounter many kinds of situations that require snapshot backup. For example, the system cannot be started; virus intrusion causes system error; inadvertent deletion of important documents. Snapshot backup can ensure that your system or files are successfully restored to the state before the failure, so it is necessary to have snapshot backups.
Typically, the snapshot is created using disk or system imaging. However, most backup software can also take snapshot backups and help system image recovery or system restore in a more efficient and convenient way.

Is snapshot backup a full backup?
No, it is not. Snapshot backup only provides system state data at a certain point in time. At the same time, the snapshot itself is not a backup, it is only an important part of the system backup process. So snapshot backup is not a full backup.
What are the types of snapshots?
Snapshots have 4 types.
Copy-on-write: Include metadata describing data blocks that have changed since the creation.
Redirect-on-write: When creating a new block, write the snapshot once.
Continuous data protection: Snapshot created in actual time. The snapshot of the original copy is updated with each change.
Mirror/clone/replication: Clone/mirror is the same copy of the storage unit, while replication is a form that can protect data.
