    Disable "Put hard disks to sleep when possible" in your Energy Saver system preference.

     

    This has solved it for me now through multiple reboots, manual backups and automatic periodic backups.

    Great! 

     

    But many (perhaps most) external HDs don't respond to that setting, so it may not work for everyone.

     

    I never had to reset my Time Machine or lose my connection to the previous Time Machine temporal nodes.

    That would not have deleted any backups, or caused you to lose access to your backups.  It does, however, cause the display on the TM Preferences panel to show "None" instead of backup dates, until the next backup is done.

    The type is large because, for those who are coasting through these discussions looking for the solution, and as this is a discussion I started, I thought it would be prudent to indicate that a solution to this problem was found. At least for users of Firewire connected drives, which do respond to changes made to this setting.

    This new problem has been solved without destroying previous backup data.

    Nothing I recommended would have done that.

     

    Reseting the TM info would not have helped to solve this problem

    But it would probably have ruled out a corrupted preference file, which is a fairly frequent problem.

     

    The whole point of Time Machine is that we should be able to keep native Time Machine access to all the temporal nodes on our backup devices.

    Nobody suggested doing anything that would cause loss of access.

     

    I am loathe to wipe out that access and am eager to help others solve issues with Time Machine without assuming we have to lose the full functionality of Time Machine.

    Who suggested any such thing?  Why do you keep going on about it?

    I could not write to my Time Machine backup after Mt Lion upgrade. I had two instances of the same backup point in my list of "Select Disk". I selected the 2nd instance of the same disk (the one not in use) and it asked me if I wanted to use both of the backup disks or just the new one. I chose just the new one and Time Machine picked up right where it left off.

    This is a Seagate FreeAgent Firewire 800 External HD and it definitely responded to changing this setting. I also have a 'cheap-o'  ($30) Welland USB External case, loaded with a 3.5" Western Digital 2TB Caviar Green Drive that has responded to this setting. That may not be many, but at least in my lucky case thats 2 of 2 or 100%.

     

    (Welland external case is USB3 but I've only got USB2 on this laptop and it still responds to drive sleep commands, obviously there are thousands of vendors out there and it's impossible to say if they'll respond.)

     

    I always prefer Firewire or Thunderbolt on Apple products for compatibility reasons, or course, USB cases would be cheaper. I'd be curious to know if anyone's had this problem with a Thunderbolt connected LaCie or Elgato drive.

     

    I've seen many instances where TM resets trigger a new backup set to be created. I'd love to know, as you're clearly well acquainted with everything TM, how does one get TM to reconnect to a backup set once TM has decided to move on. The worst case is when a system has had a new mainboard and the MAC address changes.

    Second, backups to a directly-connected drive should not be in a sparse bundle; those are used only for network backups.  Do you really have a sparse bundle on the drive?  If so, we'll need to examine it.

     

     

    Pondini, you're right. I have a folder with a .backupdb extension on the Firewire and USB connected backup devices, not a sparseimage.

    No, a reset alone won't do that.  Neither will re-selecting the drive.  Both are common fixes for various problems.

     

    If a new backup starts after that, it's because something had already happened to cause it.

    Depends on what version of OSX the Mac is running:

     

    On Leopard, there's no help from TM, but a rather wonky workaround (I couldn't get it to work, but some others did).  See #C8 in Time Machine - Troubleshooting.

     

    On Snow Leopard or later, when you do the first backup to the "new" Mac, TM should ask whether you want the new Mac to "reuse" (Snow Leopard) or "inherit" (Lion & Mountain Lion) the backups.  See #B5 in the same link.

     

    But sometimes it doesn't.  If not, effective with Lion, you may be able to do it manually, per #B6 in the same link.  As noted there, that may not work if the backups are on a network.

    Thanks! Disabling that preference seems to have worked for me (after a restart)!

    Awesome Fix THANKS!

  • xser Level 1 Level 1 (15 points)

    I am having this problem with a Time Capsule (over Wifi and over Cat5). I am using a Late 2008 aluminum MacBook (with specs that meet ML requirements). I was backing up for months on Lion. Once I installed ML, I got the following error when trying to back up:

     

    "The backup disk image “/Volumes/Data/Mac Byrd (4).sparsebundle” is already in use."

     

    None of the fixes posted here have worked. I'll be honest. I am a bit frustrated that this problem is the result of using all Apple products. If this were a beta version of ML or if the issue were with a Microsoft product, then I would understand, but a full-blown consumer release having issues with all Apple hardware and software is just plain silly.

     

    Anyone want to restore my appreciation for Apple?

    Probably because that's a different problem and a different message than in this thread.

     

    See #C12 in Time Machine - Troubleshooting.

    Thanks spurben!  That fixed the problem for me.  I did have to do a restart after disabling "put hard disks to sleep when possible" for the fix to take.

    This did not seem to fix the problem for me, is anyone else still having the problem?

  • gadget_aussie_man Level 1 Level 1 (0 points)

    I am trying the disabling of hard disk spin down to see if it fixes the problem for me.  So far it appears that the backups work if I am logged in to a user account on the server but not if the user is logged out.

     

    I will update what happens now I have changed the setting in Energy Settings.

  • flexdmc Level 1 Level 1 (5 points)

    I'm still having this problem.

    I've restarted my Airport Extreme (which my HDD is connected to) to no avail as well.
