In this guide I will show you how to setup dropbox backup as service. Some of the following information has been found here: Text Based Linux Install

Disclaimer

Even I tried myself this command sequence you are informed and you must accept any risks deriving from these documentation usage and you cannot claim any damages to me for your own actions.

Prerequisites

Registration and creating the account procedures could be complete in a more intuitive way using the graphical user interface (GUI) if you have at least one Linux box onto which forward display X connection. In order to be able to remote the GUI you should start from that linux box and allow X forwarding:

xhost +server_ip
ssh -X user_name@server_ip

It was reported that it would be possible to install DropBox following the next instructions and not forwarding X (at least it was done in Debian squeeze). Don’t run export DISPLAY. When you run dropboxd, it will print onto the text console a URI to activate the account. Copy that URI into your browser and proceed to creation of a Dropbox account. A few seconds after visiting that uri, dropboxd will complain it cannot run nautilus. Just ignore it and continue with the steps.

Howto step by step

sudo -s
groupadd dropbox
useradd -r -d /etc/dropbox -g dropbox -s /bin/false dropbox
# note that when running 64-bit you need to use http://www.dropbox.com/download/?plat=lnx.x86_64 in the next line (!)
wget -O /tmp/dropbox.tar.gz http://www.dropbox.com/download/?plat=lnx.x86
mkdir -p /usr/local/dropbox /etc/dropbox
chown dropbox.dropbox /etc/dropbox
chmod 700 /etc/dropbox
tar xvzf /tmp/dropbox.tar.gz -C /usr/local/dropbox --strip 1
rm /tmp/dropbox.tar.gz

su -l dropbox -s /bin/bash
umask 0027
# the next line is useful only if you a linux box with X
export DISPLAY=10.0.XX.YY:0.0
/usr/local/dropbox/dropboxd
# register a new account and/or register this machine. Be sure to '''do this while dropboxd is running'''
exit
