Amazon AWS (Amazon Linux AMI) Duplicity via Duply Backups to S3 installation and setup
Raw
gistfile1.txt
### Installing on [Amazon Linux AMI](http://aws.amazon.com/amazon-linux-ami/) (release 2014.09)
Installing using [yum](http://yum.baseurl.org).
By default Amazon Linux AMI release has only AWS's yum repos, but it has EPEL (Extra Packages for Enterprise Linux) predefined but not enabled. To temporarily enable the EPEL 6 repository, use the yum command line option **--enablerepo=epel**.
Run
```
sudo yum install duplicity rsync gpg python python-devel python-pip --enablerepo=epel
```
Insalling duply manually (latest version can be found [here](http://duply.net/wiki/index.php/Duply-downloads))
```
cd ~
wget http://downloads.sourceforge.net/project/ftplicity/duply%20%28simple%20duplicity%29/1.9.x/duply_1.9.1.tgz
tar -zxvf ./duply_1.9.1.tgz
sudo cp ./duply_1.9.1/duply /usr/bin/
```
Install boto for S3 support
```
sudo pip install boto
```
Test duply
```
duply -v
```
This command should output something like
```
duply version 1.9.1
(http://duply.net)
Using installed duplicity version 0.6.22, python 2.6.9, gpg 2.0.25 (Home: ~/.gnupg), awk 'GNU Awk 3.1.7', bash '4.1.2(1)-release (x86_64-redhat-linux-gnu)'.
```
### Configuring
To create backup profile (ex. www) use
```
duply www create
```
Now edit default configuration (/home/ec2-user/.duply/www/conf)
```
vi /home/ec2-user/.duply/test/conf
```

Hello friend! I don't know if you can help me. When try to run duplicity the following error occurs:

Traceback (most recent call last):
File "/usr/bin/duplicity", line 42, in
from duplicity import log
ImportError: No module named duplicity

Do you know what is going on?

I had the same issue, my default version of python is 2.7 and the package require 2.6
install python26 and replace the first line in /usr/bin/duplicity:

#!/usr/bin/python

by

#!/usr/bin/python26

TARGET_USER and TARGET_PASS won't work since duply 1.10.x. Source. Use these in config:

export AWS_ACCESS_KEY_ID='XXXXXXXXXXXX'
export AWS_SECRET_ACCESS_KEY='XXXXXXXXXXXX'

I am getting "UnsupportedBackendScheme: scheme not supported in url: s3://". Though I have confirmed I have the URL format for my buckets region correct. Has anyone else seen that issue?
UnsupportedBackendScheme: scheme not supported in url: s3://s3-us-east-2.amazonaws.com/pinknose1/backup/www/

Update - I am very new to Linux so I wanted to update this in case any others run into the same issue. The workaround for me was to simply re-create the EC2 instance I was building this on. The url structure was actually fine, however at some point one or more of the fixes I had tried to apply had corrupted my duplicity install. A fresh install resolved this issue.
