What Is an Immutable Backup?
Notas do episódio
An immutable backup is a protected copy of data that cannot be modified or deleted during a defined retention period, even by accounts that normally possess administrative privileges. Certification exams may connect immutability with ransomware recovery, insider threats, retention controls, and protection against compromised backup administrators. Attackers frequently attempt to erase or encrypt recovery data before disrupting production systems, so an immutable copy can preserve a trusted restoration point. Organizations should separate backup credentials, restrict management access, maintain offline or logically isolated copies, monitor deletion attempts, and define retention periods that meet operational and regulatory needs. Immutability does not guarantee successful recovery, so backups must still be verified, scanned when appropriate, and tested through regular restoration exercises that confirm systems and data can be recovered.
