What does the term "snapshot" refer to in data storage?

The term "snapshot" in data storage refers to point-in-time copies of data. This concept is essential for understanding data protection and recovery strategies. A snapshot captures the state of a dataset at a specific moment, allowing users to retrieve that precise version of data in the event of data corruption, accidental deletion, or any other data loss scenario.

Snapshots are tools that enable efficient management of changes in data without the need to create full copies every time, which can be resource-intensive. This efficient capability allows for quick recovery processes, as users can restore their data to the exact point captured by the snapshot. Snapshots are widely used in various storage systems and applications, providing users with flexibility and reliability in their data management practices.

Other options, such as real-time data updates, full backups, and virtual copies of applications, do not accurately describe the specific function of snapshots in data storage, which is focused on the preservation of data states rather than ongoing updates or comprehensive storage methods.
