Can I set the expires header on all objects in an Amazon S3 bucket all at once?

Question

I've got about 200k images in a bucket. They all have expires headers of 2050 but I've read you shouldn't send an expires header older than a year. I want to schedule a script to run every month and set the headers to 6 months away. Anything out there? Obviously I'd like to avoid iterating 200k objects.

Answer 1

S3 doesn't appear to support bulk updates, as its API's contain no such operations. Some third-party tools claim bulk update capability; however, I wager that they merely automate iteration.

CloudBerry Explorer freeware will be able to do it in the next release.
