Hints for installation on Debian/Ubuntu
UrBackup is distributed by a Debian package which can be installed with
dpkg -i urbackup-*.deb
Usually you can install it like this:
wget https://hndl.urbackup.org/Server/2.0.34/urbackup-server_2.0.34_amd64.deb sudo dpkg -i urbackup-server_2.0.34_amd64.deb sudo apt install -f
It has some dependencies which you can automatically resolve 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 running
dpkg-reconfigure urbackup-server. You have to copy all files from the old to the new directory first!
/etc/default/urbackupsrv you can change some settings like the TCP-port, the log file, the log level or the port on which the build-in web server will listen. It may be important to change the temporary file directory because UrBackup can use up much space there.
The web interface 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 web interface.
