Amazon S3 lifecycle retroactive application

Question

Fairly straightforward question. Do Amazon S3 lifecycle rules that I set get applied to data retroactively? If so, what sort of delay might I see before older data begins to b

Answer 1

S3 bucket lifecycle rules apply to both existing and new data in S3. In addiiton to Mircea answer:

• Lifecycle rules run once a day at midnight Universal Coordinated Time (UTC). For example, if you create a lifecycle rule on October 15 at 4:00 PM Pacific Standard Time (PST) that transitions objects after one day, then the objects are transitioned to the new storage class on October 17 at 12:00 AM UTC.
• New lifecycle rules can take up to 48 hours to complete the first run. If there are millions of objects for the rule, then it might take a few runs for all the objects to be transitioned into another storage class.
