|Looks like they offer a .deb package at http://s3download.teamdrive.net.s3.amaz ... 8_i386.deb - so installing the client should be simply
wget -Nc http://s3download.teamdrive.net.s3.amazonaws.com/3.0.273/TMDR/linux/teamdrive3-3.0.8_i386.deb
dpkg -i teamdrive3-3.0.8_i386.deb
apt-get -f install
and there is also a server package in .deb format. This is commercial software, please see their license page for more information and costs.
Please understand that 3rd party (other than from Debian or Aptosid) software & packageing might contain bugs and lead to problems we cannot support here. Your better choice therefore is always to shop solutions we provide in our repositories.
