A financial services company uses Azure to host critical applications. They need to ensure that database backups are immutable for a period of 7 years to meet regulatory compliance. They are currently using Azure Backup for their Azure SQL Databases. Which Azure Backup feature should they enable to meet this requirement?
- ABackup Immutability
- BLong-Term Retention (LTR)
- CCross Region Restore
- DSoft Delete
Show answer & explanationAnswer & explanation
Correct answer: A. Backup Immutability
Backup Immutability in Azure Backup prevents backups from being deleted or modified for a specified duration, which directly addresses the regulatory requirement for immutable backups.
Why the other options are wrong
- B. Long-Term Retention (LTR) allows keeping backups for extended periods, but doesn't inherently make them immutable against deletion or modification by an authorized user.
- C. Cross Region Restore enables restoring data to a different Azure region, which is a disaster recovery feature, not related to immutability.
- D. Soft Delete provides a grace period to recover accidentally deleted backups, but doesn't guarantee immutability for a fixed long period.
Azure Backup Immutability
A feature in Azure Backup that makes backed-up data unchangeable and undeletable for a specified retention period, even by administrators, to meet regulatory and compliance requirements.
- Prevents accidental or malicious deletion/modification of backups.
- Configured at the Recovery Services vault level.
- Essential for compliance standards requiring data retention integrity.
Memory trick: Immutable backups, like a rock, protect your data's integrity.
