Personally I use a fresh installation of Ubuntu 8.04 Hardy Heron Desktop version (32bit on one machine, 64bit on the other) and Mac OS X Leopard (10.5.3 and later) to connect to them. On my Ubuntu boxes there's no other file sharing protocol like samba (Windows sharing) or NFS activated.

So be sure to check the latest comments on this article when the 10.5.6 update is out to see if this rumor is true and if there are problems caused by that.
Here are the steps involved in setting up your Ubuntu box as a Mac file server:

In the field volume name write Backup of computername. Now FIRST chose sparse bundle disk image as the image format and THEN adjust the volume size to the size of your internal harddrive (minimum, choose more if you like) afterwards. Remember that Disk Utility won't let you make a bigger image file as you have physical hard drive space available if you don't chose sparse bundle disk image as the image format first.

Now you can close the Terminal and select "Restore from Time Machine Backup" from the Utilities entry in the menu bar and select your mounted Time Machine backup and thats it. Oh, needless to say: a gigabit ethernet connection will speed things up dramatically even compared to (draft)n-WLAN.

## Netatalk backup disk reaching maximum capacity
As [Seron](http://www.kremalicious.com/2008/06/ubuntu-as-mac-file-server-and-time-machine-volume/#comment-15122) pointed out in the comments, there is some discussion on the net regarding problems with Netatalk and TimeMachine when the backup disk reaches maximum capacity. This is due to missing support for the AFP commands FPSyncDir aka commands 78 and 78 in Netatalk. [As a commenter in an ArsTechnica forum says](http://episteme.arstechnica.com/eve/forums/a/tpc/f/942005082731/m/370002065931?r=782005065931#782005065931): "As soon as your backup volume will reach max capacity, it will self destruct because of it."
