[Plugin: BackUpWordPress] Backup not saving to Amazon S3

Hi!

I installed & configured this plugin to save my backups to Amazon S3.

When I run the backup, it says this:
2012/04/28 09:11.13: 1. try sending backup file to Amazon S3…
2012/04/28 09:11.13: Connected to S3 Bucket: LBSBackWPUp
2012/04/28 09:11.13: Upload to Amazon S3 now started…
2012/04/28 09:11.25: Backup transferred to https://s3.amazonaws.com/LBSBackWPUp/BTDFbackwpup_1_2012-04-28_09-10-34.zip?uploadId=817nioR2yrqWq49ENX5KmVRDbSsalS8rfG6I3pBgfKkRCCZQI1B7sVql7NYNwbUrJ8T8FIOR8NfakaxOMLfLsQ–
2012/04/28 09:11.25: Job done in 51 sec.

However, when I log into Amazon S3 and check the bucket, it is empty.

Ideas?
