How to create life cycle rule on S3
You do not need to create the Lifecycles manually, WPTC does it automatically for you from version 1.17.0.
Please check and ensure that you have updated your WPTC plugin to version 1.17.0 or above.
Now go to WP TIme Capsule -> Settings -> Modify Restore window you want > Save settings.
Note: We recommend you not to create S3 Lifecycles manually.
