Update: no longer needed, see Making your AFP server more Time Machine Friendly
My Macbook pro decided that it was time for some irrepairable partition corruption tonight. as such I’ve had to restore from a backup
This post is a followup to my previous post about Time machine on unsupported network drives.
if you wish to do a full restore of a Time Machine backup from what apple considers an unsupported time machine device from the OSX install DVD you will need to open up Terminal from the Utilities menu then type
mount_afp afp://username:password@ipaddressoffileserver/timemachineshare /Volumes/TM
then exit the terminal, go to Utilities > Restore this system from a backup and it should now appear in your list.
