You need to configure a long-term retention policy for backups of an Azure SQL Database that must retain weekly full backups for 5 years and monthly full backups for 10 years. Which backup retention feature should you use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Long-Term Retention (LTR) policy
Long-Term Retention (LTR) policy allows you to retain backups beyond the default retention period, with weekly, monthly, and yearly options. Option A is wrong because geo-restore is for disaster recovery, not long-term retention. Option C is wrong because automated backups have a maximum retention of 35 days. Option D is wrong because Point-In-Time Restore (PITR) retention only goes up to 35 days and does not support long-term retention.
