Installing backup-manager with the s3 upload method on Debian/Ubuntu

backup-manager is a simple and straightforward backup solution and Amazon S3 gives you reliable remote storage.

Since the backup-manager versions in Debian and Ubuntu are little bit outdated, I would recommend installing the 0.7.5 Release from the Website. While the installation of backup-manager is painless, getting the s3 part running a little bit tricky (and undocumented).
The s3 part of backup-manager is based on the Net::Amazon::S3 perl module and this needs the XML::LibXML::XPathContext module, which is, as far as I can see, not included in one of the libxml-*-perl packages in Debian or Ubuntu.

So, this procedure gives you all the needed dependencies:

sudo apt-get install libperl6-slurp-perl libxml2-dev
sudo cpan XML::LibXML
sudo cpan Net::Amazon::S3

Update: (14.06.07) Ubuntu feisty now contains the 7.5.3 version of backup-manager.
