Is there an easy way to set up a bucket in s3 to automatically delete files older than x days?

Amazon now has the ability to set bucket policies to automatically expire content:

Amazon has meanwhile introduced S3 lifecycles (see the introductory blog post Amazon S3 - Object Expiration), where you can specify a maximum age in days for objects in a bucket - see Object Expiration for details on its usage via the S3 API or the AWS Management Console.

+1 for providing an update regarding this outdated information, thanks! –  Steffen Opel Feb 26 '12 at 16:44

No, S3 is just a datastore. You'll need to use some outside client to periodically delete the old files.

This is no longer true: docs.amazonwebservices.com/AmazonS3/latest/UG/… –  Tarrant Oct 9 '12 at 23:44
    
Ah, that makes things much easier. Although, for my backups I still prefer to perform the deletion from my script, to make sure older backups are only purged when a new one has been made successfully. –  Martijn Heemels Oct 15 '12 at 8:34

You can use s3cmd to write a script to run through your bucket and delete files based on a precondition.

You'll need to write some code (bash, python) on top of it.

You can download s3cmd from http://s3tools.org/s3cmd
