Lots of tools exist out there that do backups to Amazon S3, but none quite fit our needs. In particular, though duplicity seemed to be closest, it wouldn't recreate hard links upon restore.
This system uses duplicity with an additional layer that allows us to recreate hard links.
Download the duplicity sources. As of this writing, the latest is 5.09
On Debian/Ubuntu:
$ tar xvf duplicity-*.tar.gz $ cd duplicity-*/ $ sudo apt-get build-dep duplicity $ sudo aptitude install python-boto checkinstall $ sudo checkinstall python setup.py install $ cd ..
Hit return a few times, and duplicity will have been installed.
Note
I had a little trouble with earlier versions of duplicity. I'm not sure whether that was my fault, but the latest seems to be the greatest, too.
Now either click the download link at http://github.com/techarcana/s3backup and unpack the result, or
$ git-clone git://github.com/techarcana/s3backup.git
then:
$ sudo chown -R root:root s3backup $ sudo mv s3backup/etc/cron.d/* /etc/cron.d $ sudo cp s3backup/aws_secrets.py.sample s3backup/aws_secrets.py $ sudo mv s3backup /usr/local $ sudo chmod 0600 /usr/local/s3backup/aws_secrets.py
now edit your private information into /usr/local/s3backup/aws_secrets.py.
And that should do it!
