    So I wanted to do a backup to an external HD and the estimated time for completion was 12 hours. Is this normal or is something wrong with Time Machine? My computer is only a week old and doesn't have that much stuff on it.

    Oh and yes, I did some research on this but couldn't find anything.

    12 hours is way off. Maybe try a different hard drive just to ya know, eliminate.

    My iMac is set to back up on TM automatically everyday and doesn't take very long at all.

    The initial backup will take a long time. It has to do the entire operating system and all installed programs. Once it does the initial backup, it will only take a minute or two for subsequent backups.

    Ah yes, this could be it.

    But then again, 12 hours...Still a little long. I'm sure mine only took like an hour... or so...

    Depends on how many GB you used on your mac.
    and what kind of drive the MBP and timemachine has.

    SSD would be faster.
    HDD with 5400rpm for slower will take longer time.

    HDD with 7200rpm will be faster than 5400rpm drives.

    It all depends.

    True, I think this is a 5400rpm HDD. Hopefully it's only slow the first time.

    Just leave it over night and it will probably be done.
    All computers give really long estimation time but sometimes it ends faster :p

    What type of connection are you using for the external backup drive?

    I have a 500gb hitachi with dual USB. I actually unplugged it, restarted the computer and then tried again and it only took about an hour to backup. For some reason the initial connection wasn't working. All is good now, thanks guys

    huh. I mean, the first time machine backup does take time (it took ~2 hours for me, and I only had ~100gigs on my machine at the time). But, since then, it has never taken more than 5 minutes to do a backup.

    You might want to exclude your System folder in TM prefs - most people would reinstall this fresh rather than restoring, so no point losing time & space to back this up (exclude all system files when it prompts you, as well)

    Under Options, if Encrypt BackUp Drive is checked, it will take a long time the very first time you run it.
