So recent Windows have imaging backup tools built in, which could easily be used. However, after using WHS for so long I wanted a central view and de-dupe of my backups on my new server too. I believe I found the solution for me with URBackup.
It is installed using a PPA source by running:
sudo add-apt-repository ppa:uroni/urbackup sudo apt-get update< sudo apt-get install urbackup-server
The following sets up access to URBackup from an apache subdirectory:
libapache2-mod-fastcgi sudo ln -s /var/urbackup/www /var/www/urbackup
Add following line to the ’fastcgi.conf’:
FastCgiExternalServer /var/www/urbackup/x -host 127.0.0.1:55413
Then you install the Windows client from here, install, and it backs up an image of your primary partition.
