Opalsync is an open source framework for making backup of local or remote computers. It is designed for backup to disk using rsync as backend, but can be extended with other ways.
It generally store backup data as one full copy of the latest, and then only store the differences from the previous backup syncronizations. This make it easy to restore recently lost data and saves a lot of disk-space.
You can download the latest version of opalsync from the svn repository.
There are also packages available for Debian by using the Inguza Debian package repository. Use the following lines in apt:
deb http://apt.inguza.net squeeze main
or if you are using an older version of Debian
deb http://apt.inguza.net lenny main
deb http://apt.inguza.net etch main
and then install the package using
apt-get install opalsync
