AWS S3 Glacier Flex

Question

If I create a lifecycle policy rule of 2 days on my S3 bucket to move that data to S3 Glacier Flex for Storage. 1. Will that rule move empty parent directories created by rsync to glacier flex and then charge me for filling those directories with new objects if rsync only fills those parent directories with files 2 days after the parent directory has been created? 2. Or does the flat structure of the S3 bucket prevent that?

Answer

Hi

I'm assuming you are referring to Glacier Flexible Retrieval when mentioning Glacier Flex.

Lifecycle policies support use of filters. You can filter by prefix, tags or even object size. So you can add a filter to lifecycle policy to tier objects of certain size e.g. above 128KB.
