I use tklbam from TurnKeyLinux to backup a number of Linux nodes on DigtalOcean and Amazon AWS.
However, tklbam support was broken on Ubtuntu 14.04 where you can't install the tklbam software.
Below is my workaround to get tklbam to install on Ubuntu 14.04.
As described on TurnKeyLinux web page, run the following command to setup the repository.
wget -O - -q \ https://raw.github.com/turnkeylinux/tklbam/master/contrib/ez-apt-install.sh \ | PACKAGE=tklbam /bin/bash
Then go to /etc/apt/sources.list.d and use your favourite text editor to edit the archive.turnkeylinux.org.list. Replace the term jessie with wheezy. Your file should look like this:
deb http://archive.turnkeylinux.org/debian wheezy main
Now run apt-get update to update the packages and then apt-get install tklbam to install tklbam.
