Now that the Mac has rebooted with the Time Machine drive connected, you can start a back up yourself. Even if the drive has been recently indexed by Spotlight, a reboot still appears to be necessary, whether to resolve whatever issues are occurring with backupd or not. This should cause OS X to re-index the attached Time Machine drive if it’s needed, which may be getting in the way of Time Machine backing up properly thus causing the computer to get stuck on “Preparing Backup” for a very long time.
