Time machine with unsupported network disks

by on Mar.08, 2009, under Uncategorized

Well I bought a new unibody Macbook Pro recently to replace my old one, and found that I couldn’t get Time Machine to backup to my server.

Even after using
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
at a commandline I still got “The backup disk image could not be created”
After much hair pulling and googling, I found that it was due to Time Machine calling some AFP functions introduced in Leopard
Problem with this being that my Tiger server doesn’t support these functions.
Of course the easy way to fix this was to create the image on my Leopard machine with the following command
hdiutil create -size 90G -fs HFS+J -type SPARSEBUNDLE HOSTNAME_MACCADR.sparsebundle
Obviously replacing HOSTNAME with your machines hostname and replacing MACADDR with your machines mac address for en0 minus the semicolons
Once that was complete all I had to do was copy the resulting image across to my backup drive on the server and it all worked.
