Import of duplicity.backends.giobackend

[janikvonrotz]

I'll get this error when running the script.

Import of duplicity.backends.giobackend Failed: No module named gio

I'll use

• duplicity 0.6.18
• s3cmd version 1.0.0
• gpg (GnuPG) 1.4.11
• Ubuntu 12.04.4 LTS (GNU/Linux 3.2.0-60-virtual x86_64)

Running the "naked" duplicity command throws

Import of duplicity.backends.giobackend Failed: No module named gio

The error message Import of duplicity.backends.giobackend Failed: No module named gio isn't important here, duplicity is able to do fine without it. Did you even search on internet for this message?
A very basic search (http://bit.ly/Ne4ksG) gave me this :
http://www.rfc3092.net/2013/09/missing-modules-for-paramiko-and-gio-in-duplicity-foo/
Should fix the giobackend notification.

As for why the whole thing doesn't work, this is related to the other error message you didn't notice:

NoAuthHandlerFound: No handler was ready to authenticate. 1 handlers were checked. ['HmacAuthV1Handler'] Check your credentials

Before looking deeper into what this could mean, please ensure your credentials are correct. If they are, I invite you to search more on this problem on your side first before.
I don't think this issue has something to do with the script in itself. I don't do support for duplicity here, only the wrapper script.

As you seem to be using Amazon S3, check if you configured s3cmd properly and try to get duplicity working with a minimal example before using duplicity-backup.sh. You can only begin using this script once duplicity is properly configured to access your storage backend.

Sry to bother you with this. Just got a bit frustrated trying all day to solve this issue. Neither I am a ubuntu nor I am duplcity pro. So thanks for any kind of help. Your minimal example approach is a great idea.

The error message was a little bit misleading. I didn't granted the AWS backup user the appropriate permissions. s3cmd worked properly with them, but duplicity failed.
