Are files ever deleted from AWS S3 file storage in a self-hosted Canvas?

[mcannoncns]

Hello,

I've setup my self-hosted Canvas installation to use S3 for file storage.  I have no issues uploading files to Canvas and having them stored in S3.  When I actually delete a file from the Canvas application it seems to be removed without issue.  However, when I check the S3 bucket the file still exists.  

Are these files ever cleaned up in S3, maybe as an automated job?  Or have a I misconfigured something?

Thanks for your time.

As far as I know, Canvas does not delete any file, just leaves it in your storage...
