How to Use Duplicity with DreamObjects

I’m setting up backups for a Linux machine in this tutorial. First you will need to setup a plan for DreamObjects; if you already have an account with us you can do so from the panel here, otherwise you can sign up and then head over to the panel. Once you have a plan you will want to create a user, and after submitting a user name you’ll have to periodically refresh the page to see if it is now available. Now once you have a DreamObjects user you will want to click the “1 keys” button on the right side and copy down the user key, followed by revealing the secret key and copying that.

On Ubuntu getting all of the software you need is easy:

sudo apt-get install duplicity python-boto

Now we have to take our user and secret key and put them into a file named ‘.boto’ in our users home directory. You can do this with the following commands if you substitute your own keys:

echo[Credentials]” >> ~/.boto
echo “aws_access_key_id = 98F3n8qUtWEJ6ZdBYyQy” >> ~/.boto
echo “aws_secret_access_key = p5kptXKQrsQtTNJTYtG7emGYooXkN6Kaza1OV-_s” >>

Now you can backup any directory you desire to a bucket name of your choice. In this example I’m backing up my Pictures directory to the blogdemo bucket:

duplicity –allow-source-mismatch ~/Pictures \

It prompts for a encryption password which you won’t want to forget and then syncs your files, the output should look something like this:

GnuPG passphrase:
Retype passphrase to confirm:
No signatures found, switching to full backup.

That’s it! You’ll want to run this command whenever you want to update your backups. I prefer to run it manually when I’m importing pictures but it wouldn’t be difficult to configure Cron to automatically backup a directory on your computer.

Restoring content

To restore content, you just need to reverse the source and destination values. In this example I’m restoring the Pictures directory that we backed up previously (to the blogdemo bucket) into a new Pictures_restored directory:

duplicity s3:// \
