How can I reconfigure or reinstall Time Machine in Mavericks.

I was running Lion and installed Mavericks. Now Time Machine is dimmed out in my menu bar. When I go to Time Machine preferences, there is no backup disc to select. I think I need to reinstall or reconfigure Time Machine but how?

    Mavericks "chose" to ignore my small external Time machine after opening it twice, and now no longer recognizes it being plugged-in. Thanks Apple for the major screw-up with Mavericks !!!

    Thanks for your responses. I tried erase as per Time Machine Troubleshooting but failed to 'unmount the volume' Tried the Apple Support instruction but Backups.backupdb folder could not be found. I believe that others have had difficulty with Mavericks and Time Machine compatibility.
    I am taking my external hard drive to my dealer, to be erased and then I'll re-install it.

    Where did you save your Time Machine backups to previously? Can you access that location via Finder i.e. the file share, external disk, … containing the "Backups.backupd" folder?

    Usually when no volume is visible it's a problem outside of Time Machine. Like a damaged file system, not existing or unsupported file share.

    For example if you were using a third-party solution like a Time Machine Server on a NAS there is a good chance its protocol is outdated and Mavericks simply refuses to use it. In that case you'd have to look for an update for the NAS.
