OS X Lion (10.7) Note: Lion requires some features not available in
netatalk since version 2.2.
Although you can easily find several tutorials on that subject, I compiled it into one that worked for me. Here you can find instructions necessary to create OS X Time Machine backup on remote FreeBSD machine (I haven’t checked but I’m pretty sure that similar procedure works on Linux also). Description presented here is NOT meant to be implemented literally. Try to treat it as a guideline and adopt it to your own needs and environment.
I used ports to install netatalk (AFP implementation). As
cd /usr/ports/net/netatalk/ && make install distclean
Be sure to enable Zeroconf (Bonjour) during configuration.
netatalk_enable="YES" afpd_enable="YES" cnid_metad_enable="YES"
Put following content in
"Time Machine" -uamlist uams_dhx2.so
Put following appropriate line in
/usr/local/etc/AppleVolumes.default (change path and allowed user as needed):
/home/jf/tm/ "Time Machine" allow:jf options:tm,usedots
Since filesystem provided by FreeBSD is not quite compatible with Time Machine, you have to create your own file system image. Use
Disk Utility to create image:
- Save As:
MachineNameas read from ‘System Preferences / Sharing’ Computer Name field. MacAddress has to be ethernet address of en0 - as displayed in
ifconfig en0result in ehternet line - without colons. For example:
jf_010203040506. Always use ethernet interface. Wireless interface won’t work.
- Size: Custom - greater than your HD size
- Format: I use
Mac OS Extended (Journaled)but I’m not sure which one is the best.
Single partition - Apple partition map
- Image format:
sparse bundle disk image
Resulting file should have
.sparsebundle extension. Copy it to your remote FreeBSD volume using Finder. Remember to “Connect As” correct user. Now you have to allow unsupported volumes to be seen by Time Machine; in terminal issue:
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
Now you are ready to setup Time Machine in System Preferences. You should see remote volume as “Time Machine”.
