So actually I didn't have the latest AES with me, so I just looked up an old document. It should still be valid for most part for you.

For most of the maintenance job for AES is handled by  CleanupAESData. 

Some of the activity such as purgeEmailAttachments, purge old data, PurgeLogUsageData  etc.

So you can cross check the activities getting called here and check the functionality in this.

Let me know if this helps or I will install AES and update you on specific query (if you have any)
