I setup a samba share, and thought I would be good to go until I got a message “the backup disk image … could not be created (error 45)”. So I went to google and did some research. The first site said to create an AFP share on your file server (in my case Debian). That looked like too much work, so I went to the next option, which was much simpler. Create a local image file, copy that to your Samba share, and then fire up Time Machine. This worked great.

1. hdiutil create -size 200g -fs HFS+J -type SPARSEBUNDLE -layout SPUD -volname “Backup of $MACHINENAME” $MACHINENAME_$ETHERNETID.sparsebundle

Get the machine name from Preferences -> Sharing.
Get the Ethernet ID (aka mac address, aka physical address) from Preferences -> Network -> Ethernet -> Advanced -> Ethernet

2. cp -r file-you-just-created /Volumes/BackupLocation

3. defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

Then fire up Time machine select your network drive as the source drive, and you’re good to go. Works like a charm.
