Best way to manage an S3 Bucket?

I have been trying for a month and a half now to transfer files and update ACL permissions.

My开发者_如何学C bucket in question is 28gigs, and has over 45,000 objects in it.

It generally takes three days to do it. I've tried the following :

• Bucket Explorer
• CloudBerry
• s3sync
• s3cmd
• s3 organizer
• s3fox

And quite frankly, none of them can handle it. All of them die after a few hours of running the process of copying these files or updating their ACL's.

Does anyone know what I can do?

Sorry for stating the obvious here but why not update them in multiple sessions?
