Hi.

 

I updated the OS X today and erased my external hard drive.

 

Time machine doesn't seem to want to run properly.

 

It says 'preparing backup' for at least 25 minutes and just keeps working.

 

Is this normal?

 

The computer appears to still be indexing and says it's going to take another three hours.

 

Should I wait until that completes and then re-try Time Machine?

    Mine did that too.

    Turn TM off in your System Prefs.

    Erase the disc again.

    Unmount it.

    Remount it.

    Open TM Prefs.

    Choose it again

    It'll begin the backup.

    That didn't work C F McBlob.

     

    I'm going to try and be patiend like Scott says, unless anyone else has more suggestions.

    arizonadonn,

     

    For what it's worth, I had the same problem...TM seemed to hang in the preparing backup mode. 

     

    I opened Console, and saw a message:

     

    BLM com.apple.launchd.peruser.501[187] (com.hp.help.tocgenerator): Throttling respawn: Will start in 9 seconds

     

    This process kept repeating itself, and seemed to keep Time Machine from properly preparing...  A google search showed that the com.hp.help.tocgenerator was trying to update an HP help file after the update to Mavericks...

     

    I went into the HD/Library/LaunchAgents folder, and deleted the com.hp.help.tocgenerator plist file, rebooted my computer.  The respawn message went away, and my Time Machine backup began normally...

     

    Normally your Library folders are invisible, since you really ought not muck about in them.  However you can make them visible by clicking on View>Show View Options and check the "Show Library Folder" box...

     

    Hope this helps...

    I had the exact same problem. I even got the message that Bob referenced (though with a different plist). I tried his solution, but the problem just moved to a different file.

     

    Mine did take forever though... I think it took 12 hrs preparing backup at one point... and then it would run and seemingly hang for hours with nothing listed in console. 


    Eventually, the backup did complete. It's worth noting that for the next several (SEVERAL) backups, it seemed to take forever. The external drive is a 3TB, USB3 drive. The internal drive is a 1TB drive. My latest backup comparitively took no time at all. 7 minutes including pre and post work. (~200MB)

    There have been a lot of discussion threads about how slow Time Machine is in Mavericks, especially when starting a new backup. For some it has gotten faster with time. Turn it on and let it run overnight after Spotlight stops indexing. For what it is worth, the clock in the menu bar doesn't work on our 2 computers??

     

    Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

    same problem: Mavericks installed, Time Machine won't exit Preparing Backup. None of the proposed solutions work for me...

    Hi.

     

    I called support. Nothing worked.

     

    They had me reboot with my shift key down. I guess that starts the SAFE mode.

     

    I did a backup in about 8 hours.

     

    Rebooted.

     

    Now the smaller backups work perfectly.

    Yes.
