    Did you enable Time Machine backup? The MTMD process relates to Spotlight indexing service. I think it's tied with Time Machine.

     

    Go to:

    • System Preferences
    • Time Machine
    • Options
        • Deselect Create Local Snapshots
    • Restart Mac

    Try This: Disconnect all users from the time capsule To manually disconnect all users from the Time Capsule, open the Airport Utility and choose the Time Capsule device on the list to the left. Then click the "Manual Setup" button and select "Disks" in the resulting window. Then click the "Disconnect All Users..." button, quit the utility, and reattempt the backup.

     

    Also Do This:

    1. go to system preferences

    2. go to time machine

    3. click change disk

    4. select none

    5. turn time machine off

    6. click change disk again

    7. select your external HD

    8. turn it back on

    If you have external backup other than Time Capsule, you can erase Time Capsule disk to take backup from scratch, However I won't recommend unless you have proper backups on elsewhere!

     

    If possible, try to connect Time Capsule directly to your MacBook using Ethernet cable and do the backup again.

    Try to Close Finder by using Force Quit.

    Disable All Startup Items or Restart Mac in Safe Mode. Start the Time Machine Again to take backups.

    mtmd is Mobile Time Machine Daemon.  It does have to do with Local Snapshots on portable Macs.

     

    See #30 in  Time Machine - Frequently Asked Questions.

    Did it prompt you for your password, and did you type it and press Return?

     

    If you're not sure, do it again and post a screenshot.
