DynamoDB - Backup and Recovery
You enabled PITR on a table Users 10 days ago. Today, you want to restore it to the state exactly 40 days ago. What will happen if you try to restore using PITR?
AThe restore will fail because PITR only supports recovery up to 35 days in the past
BThe table will be restored to the closest available backup at 35 days ago
CThe table will be restored to the current state since 40 days is out of range
DThe restore will succeed and recover data from 40 days ago
Step-by-Step Solution
Solution:
Step 1: Recall PITR retention period
PITR supports restoring data only within the last 35 days from the current time.
Step 2: Analyze restore request for 40 days ago
Requesting restore beyond 35 days is outside PITR limits and will cause failure.
Final Answer:
The restore will fail because PITR only supports recovery up to 35 days in the past -> Option A
Quick Check:
PITR limit = 35 days; 40 days restore fails [OK]
Quick Trick:PITR max restore window is 35 days only [OK]
Common Mistakes:
MISTAKES
Assuming PITR can restore beyond 35 days
Thinking restore auto-adjusts to closest backup
Confusing PITR with manual snapshot backups
