After you enable lifecycle management for a file system, the files that meet the lifecycle management rules are dumped to the IA storage medium of the file system. If you want to frequently access some files stored in the IA storage medium, we recommend that you retrieve the files. This way, you can prevent the traffic fees incurred when you read data from or write data to the IA storage medium. This topic describes how to the view files that are stored in an IA storage medium. This topic also provides further details about how to manage data retrieval jobs.
