Time Machine backups have not worked since upgrade to Lion OS X

I get the following error message when trying to use Time Machine - "The backup was not performed because an error occurred whilecopying files to the backup disk.  The problem may be temporary. Try again later to back up. Ifthe problem persists, use Disk Utility to repair your backup disk."

Not one of Apple's better messages. 
It's having a problem with a particular file, but there's no hint of that.

  • Time machine backups have slowed considerably since my installation of Mavericks -- why?

    Ever since installation of Mavericks, time machine backups have slowed to a crawl.  The message preparing backup used to to take 10 seconds to a minute, now it takes 5 minutes.  The status of the backup used to show 10mb's of 80 mb's backed up, and take under 1 minute, now it takes 5 minutes.  Finally cleaning up notice, and the time to clean up has increased significantly.  My backups go to an external HD (7200rpm) connected vis firewire 800, that has approx 180 gigabytes available of its 1 terrabybyte capacity. 

    I upgraded to Mountain Lion a few weeks ago. Everything was fine with Time Machine until a few of days ago.
    Same problem others described: extremely slow, taking hours to back up just a few MB.
    I verified the Time Capsule drive and my Mac hard drive - no problems found.
    I then erased the Time Capsule and started Time Machine. It did the full backup in a fairly reasonable amount of time (several hours, but not unexpectedly long).
    When it started its first incremental backup, it reverted to the same problem: extremely slow, but it did finish eventually.
    I then shut down the Mac and restarted (power cycled) the Time Capsule. Then I started up the Mac and told Time Machine to back up now. It backed up 30+ MB in just a few minutes, so it seems back to normal. We'll see how it goes when the next scheduled backup starts up.
    But you might try rebooting the Time Capsule (and your Mac).
    By the way, when it was in the middle of the extremely slow backup, I disabled Norton Anti-virus and it didn't seem to speed it up any. But I left it disabled after I rebooted the Time Capsule and had a successful incremental backup, so I'm not sure yet if Norton is a factor.

  • Time Machine has not worked since upgrade to Lion

    Hello,
    I've noticed that my Mac Mini's Time Machine will no longer perform a backup - I keep receiving a "could not create the backup folder" error message. This problem only started after I upgraded my Mac Mini (2010 Model) to Lion, Time Machine had worked perfectly when I use to use Snow Leopard. I have both formatted and partitioned my Time Machine drives (the first drive was a Seagate Barracuda 7,200 RPM 1TB drive, the 2nd drive is a 2TB Porsche Drive I bought at my local Apple Store). Both drives, when I was partitioning them, were set to use the GUID Partition Scheme. The Seagate Drive is an Internal Hard Drive that is sitting in a ThermalTake 2-Bay Drive Dock which is connected by a USB Cord, the Porsche drive is an External Drive that is connected via a USB cord. I have also tried unmounting/remounting each drive, deleting the Time Machine "plist" file from my Library folder and restarting, and finally re-installing Lion from the recovery drive I made using the instructions on support.apple.com. Unfortunately, nothing I've done so far has solved the issue.
    I checked my Console log for Time Machine and this is what I found:

  • Time machine backup is not working

    I have tried three different times to restore my computer from a time machine backup. Each time it gets stuck on the Apple logo screen once it it is done restoring the information. Not sure what to do.. every time I restart it by holding the power button it gets stuck on the same screen.

    Read all the info about restore in Pondini.. I am not sure what you are looking at but he goes through the different methods here.
    http://pondini.org/TM/Home.html
    See info for setup assistant and migration assistant.
    More particular info from inside the OS.
    http://pondini.org/TM/FAQ.html
    Q14-17
    The backup could be corrupt.. and it can take a long time to work over wireless .. it is really important to use fastest possible connection.. if you are talking Time Capsule that is ethernet.. if you are talking external drive that is whatever is the best external drive system you have available.
    Pondini also has info on how to verify the backup is working and to fix minor issues.
    See A5 here. http://pondini.org/TM/Troubleshooting.html
    Let me add.. TM is great when it works .. and it is a dog when it fails.. Of late.. it fails alot. Yosemite being the worst possible. If you are trying to restore a computer having loaded Yosemite it is probably no longer possible to recover back to what you were running.

  • Photos gone and Time Machine Backup does not work.

    I did a rebuild of my thumbnails at iPhoto's suggestion, then left the room because it took too long. When I came back all the photos and albums etc were gone, not exclamation points but missing.
    I thought iPhoto could not find the library so I tried the option + open and chose the proper library. Still opened to an empty library. According to the library file it was 102 GB in size but oddly had no information. I did not panic because I back up ALL the time. When I tried the TimeMachine backup (each of them back to March) they also said over 100GB but when I started to transfer them it totaled only 1019 MB and now I have exclamation points and no photos. So I need help getting back the photos. TimeMachine is the ONLY backup I have. Is this an iPhoto problem or a problem with TM? In older versions of iPhoto there was a folder of folders that had all my pictures by roll number did that change in this version, because I can't find that either? FYI all photos, and library, are (were) on an external drive.
    Not gonna lie I am in a bit of a panic at this point. Any help would be greatly appreciated.
    I can clarify anything that does not make sense, I tried to keep the explanation as short as possible so people would read it!
    Thanks in advance,
    FatherTime

    Do you still have your original library that started this problem? If so use Time Machine to bring forward the last backup before the problem happened. Do not replace the current library with the backup but select the option to keep both.
    Open the recovered library and drag out the Library6.iPhoto file to the desktop and move the rest of the recovered library to the trash. Open your original library and replace the Library6.iPhoto with the file from the recovered library. See if iPhoto will open and recognize your photos now.
    If you had any imports between the time of the last backup and your current library they will not be recognized in the library but will be inside the library non the less. You can find their event folder in the Originals folder, move it to the desktop to reimport.
    TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
    I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

  • Time Machine backup does not work after 10.7.2 update

    Hi,
    after updating to 10.7.2 time machine does not perform any backups on my time capsule (error-1). What can I do? Please help. Thanks.

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)

  • How, specifically, do I restore Time Machine backup of Snow Leopard after upgrading to Lion?

    I upgraded to Lion and cannot access my Quicken files. I understand that I have to go back to Snow Leopard to export the Quicken files, but I don't see how to restore Snow Leopard from Time Machine. Or, how to boot up directly to the external drive, which was also suggested as a solution.

    Stanley Horwitz wrote:
    Reinstall Snow Leopard from the original media,
    You don't need to do that;  just start up from the Snow Leopard Install disc and do a full restore from your last Snow Leopard backup, per the link posted by OGLETHORPE.

  • Time Machine options are not working. I am unable to schedule automatic backups.

    Time Machine options are not working. I am unable to schedule automatic backups.  The On-Off button is grayed out. I can perform a backup manually.

    Thanks for responding.  I have an external disk with plenty of room.  It is used only for backup of my computer.  I get a backup by clicking on the Time Machine icon at the top of the page and select "Back Up Now."  When I click on Time Machine Preferences, there is a box labeled "Options" which allows me to exclude items from backup and notify after old backups are deleted.  There is no option to schedule a backup.  The "OFF/ON" box is gray.  For "Next Backup:" it says "Automatic backups off."  I would like to turn it on.

  • Yeah. Got a time machine backup, should that work? Thanks.

    Yeah. Got a time machine backup, should that work? Thanks.

    You can schedule backups in CCC for whatever you like. I run two CCC clones on separate disks - a weekly backup and a daily backup. You could have an hourly backup too, if you wish. You can choose to back up on some days and not others (e.g., you might not do any work on the weekend, so see no point in having a backup schedule run on those days. In this regard, CCC is far more flexible than TM.
    It's also more versatile in the backup options it will allow you. Once you've restored your system to the good, I would forget about only cloning your User account, and clone your entire internal disk. This is what most people do I believe, because not only will this copy everything (literally, clone your disk) unlike Time Machine (which skips certain items), it will also make your backup bootable (again unlike Time Machine).
    That menas if your internal disk ever goes kaputt, or you wreck your system with an update or upgrade, you can simply boot back into your system in minutes by connecting the clone.
    About the only advantage I see that TM has over a bootable clone is the 'star wars/versions' type interface, which makes restoring individual files much simpler and user friendly than a clone (but since it's not that hard to do it with CCC anyway, that personally doesn't bother me too much). Others on this board will argue that TM is faster (not in my experience) and causes less wear on your drive (mines happily going 3 years later, but there's no way to empirically test this claim, AFAIK).

  • Time Machine backups do not migrate from iMac to MacBook Pro

    I just moved from a iMac G5 to a MacBook Pro. I love Apple's migration tool, but it seems that Time Machine backups do not migrate.
    I checked with support, and did a basic amount of searching, and it seems that I need to erase and reformat the backup drive, losing all of my backups.
    Can this be true? That's a pretty screwy backup solution.
    Is it possible to rename the backup folder from "iMac G5" to "MacBook Pro"?
    Is it possible to add a MacBook Pro backup folder to the one already there?
    Any help is appreciated.

    I'm not quite sure what you mean. It sounds like you successfully migrated, and got everything set up properly on the new Mac.
    Now you want TM to just continue backing-up the new Mac to the old Mac's backups?
    If so, then no, that's not going to work. TM keeps the backups for each Mac completely separate. This is usually an advantage, so you can back up two or Macs to the same drive without any conflicts.
    Plus, the version of OS on your new Intel laptop is very different from the one from your old PPC desktop; a whole different set of drivers, and of course code for Intel vs. PPC.
    So TM on the new Mac cannot treat the old backups as if they were from the new Mac. It must start a whole new "sequence" of backups for the new Mac. If there's room on the disk, you can leave the old backups there until you're sure you don't need them, but that presents another problem: when you want to delete them, you can do it only one at a time, via TM, using the procedure in item #12 of the Frequently Asked Questions *User Tip* at the top of this forum. That's rather tedious and time-consuming, so most folks just erase the TM drive and let it start fresh.
    If I've misunderstood, please clarify the situation.

  • "Time Machine Backups" could not be unmounted (Disk Utilities)

    Hi there,
    I am having an error message when trying to back up time machine.  Therefore I went to disk utilities and verified disk.. said it needs to be prepared.  When I try to repair time machine, i then get the following message "The disk “Time Machine Backups” could not be unmounted".  I tried again and then it says its been repaired.  so when i tried a backup of time machine i get "time machine error.  unable to complete backup. an error occurred while copying files to the backup volume"
    I have installed "Time machine buddy" and I am getting"error reading system logs"
    I have a mac osx 10.5.8. No antivirus or spotlight running that i know of.
    Any ideas?

    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode, see if external Drive can be repaired...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    Open Console in Utilities & see if there are any clues or repeating messages when this happens.
