Duplicity

Unable to backup to European Amazon S3 bucket

Asked by Martin Fisher on 2015-09-26

Hello!

I am testing Duplicity with the intention of using it for some large backups to Amazon S3. My preference is to use European (Frankfurt) buckets rather than US Standard. If I do a test with

export AWS_ACCESS_KEY_ID="..."
export AWS_SECRET_ACCESS_KEY="..."
duplicity --no-encryption /home/martin/Desktop/backup-this s3+http://testing.backup.usstandard

The backup runs fine to the pre-created US Standard bucket. But if I test with

export AWS_ACCESS_KEY_ID="..."
export AWS_SECRET_ACCESS_KEY="..."
duplicity --no-encryption --s3-use-new-style --s3-european-buckets /home/martin/Desktop/backup-this s3+http://testing.backup.frankfurt

to the pre-created EU Frankfurt bucket I receive this output:

I am running Duplicity on Ubuntu 15.10 and have added the ppa for both Duplicity and python-boto so that I have the latest versions (0.7.05 and 2.34, respectively).

If anybody could advise me, I would be grateful.

Thank you, Martin
