What is the execution frequency of the Lifecycle rules?

The triggering of lifecycle rules is an automated process that is triggered at 12 am UTC[1] and we list the objects in your bucket and find the objects eligible for storage class transition or expiration (deletion). Then, the actions are applied on the objects asynchronously[2]. Depending on the number of objects, it could take a few days for the actions to complete, especially if there are millions of objects eligible for changes.

You can refer to this article to troubleshoot why isn't the lifecycle rule on your Amazon S3 bucket working even though you applied it more than one day ago [3].

Hope this helps,

Jon

My bucket has 2 folders/prefix: stage and archive.

Requirement: all files older than 1 day located in the "stage" folder must be moved to glacier area. the others must remain in the standard area.
