Cheap Time Capsule alternative using Ubuntu 12.10

Why spent $260 for Time Capsule, when You can make Your Ubuntu to act exactly the same? Here is how to do this.

First we’re gonna install couple of things that we need for further setup:

sudo apt-get install avahi-daemon libavahi-client-dev libdb5.3-dev \
db-util db5.3-util libgcrypt11 libgcrypt11-dev

Then download the latest version of Netatalk – Open Source AFP fileserver. We’ll use netatalk 3.* because its much easier to setup as Time Capsule. Because the latest version in repositories is 2.2.* we’ll have to compile it by ourselves.

tar xvjf netatalk-3.*.tar.bz2
cd netatalk-3.*
./configure --with-init-style=debian --with-zeroconf
make
sudo make install

When everything is installed it’s time to do some configuration. First we’ll create a dir when we we’ll store all time machine backups.

sudo mkdir /media/Time-Machine/

Then we’ll add new user called timemachine, who will own this directory

sudo adduser timemachine
# here comes some data that You'll have to fill up
sudo chown -R timemachine. /media/Time-Machine

Now we’re ready to edit /usr/local/etc/afp.conf

;
; Netatalk 3.x configuration file
;

[Global]
; Global server settings

uam list = uams_guest.so, uams_dhx.so, uams_dhx2.so,

; [Homes]
; basedir regex = /xxxx

; [My AFP Volume]
; path = /path/to/volume

[Time Machine MediaPC]

path = /media/Time-Machine
time machine = yes

Then it’s time to configure avahi-daemon which will propagate our Time Capsule over the local network.
Let’s create /etc/avahi/services/afpd.service

<?xml version="1.0" standalone='no'?>
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<service-group>
    <name replace-wildcards="yes">TimeCapsule %h</name>
    <service>
        <type>_afpovertcp._tcp</type>
        <port>548</port>
    </service>
    <service>
        <type>_device-info._tcp</type>
        <port>0</port>
    <txt-record>model=Xserve</txt-record>
    </service>
</service-group>

So let’s start everything

sudo service netatalk start
sudo service avahi-daemon start

# to ensure that netatalk will start on boot
sudo update-rc.d netatalk defaults

Now You can enjoy your fresh Time Capsule alternative for the cost of HDD :)

This guide should also work for Raspberry Pi, XBMCbuntu, Debian 6.
