Recently I purchased a new home server of which I am using to backup both my iMac and MacBook Pro, I thought I’d quickly document how I achieved this for future reference and also to help others too! – Both my Apple Mac computers are running Apple MacOSX 10.7 (Lion)..
Firstly we need to install a few packages, on your Ubuntu 12.04 server, firstly check that you’ve updated your sources by runnings:-
sudo apt-get update
Now we’ll installed the required packages…
sudo apt-get install netatalk avahi-daemon
Now we need to create a backup directory, I personally created a seperate partition for this but if you have a standard install of Ubuntu and therefore under a single partition you’ll need to create a directory to store your time machine backups, you can do this like so:-
Now we have to change the owner of the folder to a system user, I’ve created an account on the server like so and named the account ‘timemachine’ – this is the account you will need to type in on your Mac when choosing the Time Machine backup target.
useradd timemachine -M passwd timemachine (The enter a password, this is what you will need to use when connecting to the time machine drive.)
chown -R timemachine:timemachine /timemachine/
Next we need to modify the following file like so:-
sudo nano /etc/netatalk/afpd.conf
You need to add the following line to the bottom of the file:-
- -tcp -noddp -uamlist uams_randnum.so,uams_dhx.so,uams_dhx2.so -nosavepassword
Now save and close the file (CTRL+O, CTRL-X)
Next we need to modify the file located /etc/netatalk/AppleVolumes.default, again we need to add another line at the bottom of the file as follows (replace <username> with the username you choose, In my case it would be ‘timemachine‘):-
/timemachine TimeMachine allow:<username> cnidscheme:dbd options:usedots,upriv,tm
We’re almost done, just one more file we need to create:-
Now populate the file with the following:-
<?xml version="1.0" standalone='no'?><!--*-nxml-*--> <!DOCTYPE service-group SYSTEM "avahi-service.dtd"> <service-group> <name replace-wildcards="yes">%h</name> <service> <type>_afpovertcp._tcp</type> <port>548</port> </service> <service> <type>_device-info._tcp</type> <port>0</port> <txt-record>model=MacPro</txt-record> </service> </service-group>
That its! – Just restart a couple of daemons and your new TimeMachine backup server is ready for use 🙂
restart netatalk restart avahi-daemon
Done! – Congratulations… You now have a remote timemachine backup server or which you can use to backup multiple MacOSX machines too… I am currently using mine to backup my iMac and my MacBook Pro!
