How to Remove Delete Markers from Multiple Objects on Amazon S3 at once

I have an Amazon S3 bucket with versioning enabled. Due to a misconfigured lifecycle policy, many of the objects in this bucket had Delete Markers added to them.

I can remove these markers from the S3 console to restore the previous versions of these objects, but there are enough objects to make doing this manually on the web console extremely time-inefficient.

Is there a way to find all Delete Markers in an S3 bucket and remove them, restoring all files in that bucket? Ideally I would like to do this from the console itself, although I will happily write a script or use the amazon CLI tools to do this if that's the only way.

Thanks!

You would need to write a program to:

• Loop through all objects in the Amazon S3 bucket
• Retrieve the version IDs for each version of each object
• Delete the delete markers

This could be done fairly easily using the SDK, such as boto.

The AWS Command-Line Interface (CLI) can also be used, but you would have to build a script around it to capture the IDs and then delete the markers.
