Hints for installation on Debian/Ubuntu
UrBackup is distributed by a normal Debian packet which can be installed with 'dpkg -i urbackup-*.deb'.
There is a dependency to Python which is used to generate the diagrams in the web interface as well as to cURL and crypto++. You can automatically resolve those dependencies by running apt-get -f install. If it does not work you probably chose the wrong packet from stable/testing/unstable.
During the installation you will be asked for the directory your backups will be saved in. This directory can be changed by doing a 'dpkg-reconfigure urbackup-server'. You have to copy all files from the old to the new directory first! In '/etc/default/urbackup_srv' you can change some settings like the TCP-port, the logfile or the loglevel or the port on which the included webserver will listen. It may be important to change the temporary file directory because UrBackup can use up much space there.
The Webinterface is available at port 55414. To restrict the access you have to create an admin account in Settings->Users. Without this account everyone can access all Backups using the webinterface!
