Time Machine and SMB

January 5th, 2009 No comments

I wanted to use my MacBook and Leopards Time Machine with an SMB share but  it could not find the shares, so I used google to finde the following hints, enter:

defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

into your Terminal. This will enable Time Machine to find network shares as well.

Now you have to create an image file, also via the Terminal:

hdiutil create -size 250G -fs HFS+J -type SPARSEBUNDLE -volname “SOMENAME” HOST_YOURMAC.sparsebundle

because the options where a bit confusing, here are the important details about this command:

-size 250G

The maximum size for our backup. The backup image will not get bigger than 250GB in this case.

-volname “SOMENAME”

You can enter any name you want for your backup, but avoid spaces and special characters.

HOST_YOURMAC.sparsebundle

HOST is the name of the Computer you want to backup. You can find this name via Sharing in your Preferences.

YOURMAC  is the mac adress of your en0 device. Enter:

ifconfig

into the Terminal, and search for ether in the en0 section. Enter the mac adress without colons.
