How can immutable backups enhance data protection strategies?

Immutable backups provide added protection against ransomware by preventing unauthorized modifications because they are write-once, read-many (WORM) storage systems. Once data is written to immutable backups, it cannot be altered or deleted until a set retention period has expired. This ensures that even if ransomware attacks the primary data source and tries to encrypt or corrupt the data, the immutable backup remains unaffected and can be used to restore the original, unaltered data. This prevents malicious actors from tampering with or deleting backups to further their attack, thereby safeguarding the data against ransomware threats.
