    Come on, guys, read a few of the recent posts:

     

    A "10.7.5 supplemental update" was released on October 4, including a fix for indexing and slow backups.  There are dozens of posts in this and a couple of similar threads saying it does.

     

    Available via Software Update, the App Store, or directly from: http://support.apple.com/kb/DL1599

    I first thought that this was probably why my 10.7.5 reinstall worked for me, but I notice that SU lists this latest 'supplemental update' as an Update for my once effected MacMini.

     

    I'm with you, although I fixed this with a complete reinstall of 10.7.5, the team at Apple have obviously tracked down how to fix it without a complete reinstall + you get a couple of other tweaks along the way.

    This worked for me with Mountain Lion 10.8.2 on a brand new mac mini.

    problem might be from using an old time machine USB2 drive from 10.7.x

    I have not re-enabled spotlight yet, but had a successful back up.

    It seems you did not read posts about the Lion Supplemental Update. I suggest you to do so

    I'm pleased to join the group reporting that "10.7.5 supplemental update" appears to have fixed the problem.

     

    My TM backups are working now, and taking a reasonable amount of time, rather than the hours/days they were taking before. And this time, unlike the assorted fixes which only helped for a little while, it's been running that way for a couple of weeks.

     

    The "Waiting for Index" entries no longer plague my logs.

     

    I'd say Case Closed on this one, at long last.

    Sorry, but Time Machine is still 100x slower than making a clone of my WHOLE system disk.

     

    What's the point of Time Machine if its this slow now.

     

    It used to be very fast, and YES, I have the updates installed for 10.7.5

     

    Cra'p.

    In most cases, it should be a bit faster.

    I killed the prefs file for Time Machine and rebuilt the TD disk. Subsequent TM backups seem to be running faster now, but still nowhere remotely as fast as in 10.7.4

     

    Preparing and cleaning-up after are both amazingly slow.

     

    I am going to switch TM off, and only do run it when I am not busy, or at dinner etc now. What a loser TM has become.

    Then something else must be wrong.  Try everything else in #D2.

    Your call, of course, but you'll be much safer if you fix the problem and let it run.

    Well, before I did anything I did Verify Disk: 0 problems,

    and Repair Permissions: 100s of problems with DisplayPrefs for some reason. These have been around for months.

     

    Then I reformatted the TM disk, and killed the prefs and restarted.

     

    Not sure what else I can do.

    That's odd.  Could you post a few of those messages?

     

    But permissions issues shouldn't affect backups, since they run as the "root" user which has permission to everything.

     

    Then I reformatted the TM disk

    Just to be sure, it does have the GUID partition map scheme, right?

     

     

    Not sure what else I can do.

     

     

    In the green box in #D2 of Time Machine - Troubleshooting:

     

    Items #1, 2, 5, and 9 through 17.

     

    What's your setup?  What are you backing-up to?

    My fast 750GB main disk is partitioned GUID, yes. With HD and TM volumes, and some other volumes too.

     

    The thing is this, in 10.7.4 it was fast (not blindingly, but pretty good)

     

    Now its more than twice as slow in all cases. I even cloned my HD using Carbon Copy Cloner a few weeks ago, then carbon'ed it back to the HD, fully de-fragged. The whole system ran faster, but TM is still just as slow.

     

    Thanks for your help, very much, but f**k TM, I will just do CC once a week. Bootable too.

    I have that update and it still does not work for 10.8.2.  I have an open bug with Apple which they want more info on.

     

    Thanks

    This is the Lion forum, so of course the 10.7.5 supplemental update isn't going to work for you. 

     

    See #D2 in Time Machine - Troubleshooting;  it has a number of possible causes and fixes.

     

    If nothing there helps, you should probably post a new thread in the Mountain Lion forum.
