Description: An immutable backup is a type of data backup that cannot be altered or deleted once it has been created. This feature ensures data integrity, protecting it from unauthorized modifications, accidental deletions, or malicious attacks such as ransomware. Immutable backups are essential in environments where information security is critical, such as in financial, healthcare, and organizations handling sensitive data. These backups are stored in systems that implement strict retention policies, ensuring that the data remains intact for a specified period. Additionally, they often utilize advanced storage technologies, such as write once, read many (WORM), which prevents any changes to the data once it has been written. Implementing immutable backups not only helps comply with data protection regulations and compliance requirements but also provides an additional layer of security in disaster recovery, allowing organizations to restore their systems to a previous state without the risk of data corruption.
