Changing your retention period

You can use AWS Backup to increase or decrease the retention period for your existing continuous backup rule. The minimum retention period is 1 day. The maximum retention period is 35 days.

If you increase your retention period, the effect is immediate. If you decrease your retention period, AWS Backup will wait until enough time passes before applying the change to protect against data loss. For example, if you decrease your retention period from 35 days to 20, AWS Backup will continue to preserve 35 days of continuous backup until 15 days have passed. This design protects your last 15 days of backups at the time you made the change.

When a retention period of an Amazon S3, Amazon RDS, or Aurora continuous recovery point has changed (increase or decrease), that recovery point status will become STOPPED. A new continuous recovery point with the altered retention settings will be created.
