What is backup in DBMS explain in detail?

Backup in a Database Management System (DBMS) refers to the process of creating a copy of the database to prevent data loss in case of failures such as hardware malfunctions, software bugs, or accidental deletions. Backups can be classified into full, incremental, and differential types, with full backups capturing the entire database state, incremental backups saving only changes since the last backup, and differential backups storing changes since the last full backup. Regular backups are crucial for data integrity and recovery, enabling organizations to restore their databases to a specific point in time. Efficient backup strategies often involve scheduling, automation, and secure storage to ensure data is protected and can be quickly retrieved when needed.
