Apple Time Machine and Netatalk 3

OS/X can't use Samba for TimeMachine backups. You have to install a new version of netatalk. I compiled 3.x from sources because the Debian version was too old (2.1)

Build

Download source from http://sourceforge.net/projects/netatalk and build netatalk. Currently I am using 3.1.0

# install build prerequisites
sudo apt-get install build-essential libdb-dev
# download and unpack tar ball
# cd into source folder
./configure
make
sudo make install

Configure

Change the volumes to use extended attributes by editing /etc/fstab and add user_xattr to the options

This is my current afp.conf file

I used to start netatalk at boot by putting it in /etc/rc.local but then I installed the standard 2.2 package and removed it, and it left behind nice startup and config scripts that I recycled

apt-get install netatalk
apt-get remove netatalk

Edit /etc/init.d/netatalk Edit /etc/default/netatalk

bwilson@bellman:~$ cd /usr/local/etc
bwilson@bellman:/usr/local/etc$ cat afp.conf
