Using Time Machine with Samba
- Create a sparse bundle disk image
- Open Network Utility and make a note of your computer's hardware address
- Open Disk Utility
- Click New Image
Save as: yourcomputername_hardwareaddresswithoutcolons. For example, if your computer name is "bob" and your hardware address is "00:12:ab:cd:ef:34", your image name would be bob_0012abcdef34.
- Volume name: Backup of bob
- Volume size: Choose how big you want your backup volume to grow to.
- Image format: Sparse bundle disk image
- Click create (save it locally and copy it to the samba share.)
- Configure Time Machine to see network volumes:
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
- Now when you go into Time Machine preferences you should see your network share available.
