Time machine -- does it reinstall problems?

My computer refused to boot, and disk utility said the HD could not be repaired. So, I erased the HD, reinstalled SL, and restored from TM backup (through migration assistant). After, a week same thing happens again, computer cannot boot and HD irreparable (see also my previous thread http://discussions.apple.com/thread.jspa?threadID=2442378&tstart=0). I took it to Apple, asked them to replace the HD, but they claim it is a software issue. And if I restore from TM backup, it will happen again.
But what kind of software error can cause the HD to become corrupted and unbootable? I would think it's only low level system routines or a virus. But if I restore from TM backup, I assume the low level system is not restored, so the problems shouldn't carry over.
So, should I do a clean install instead of restore from TM? That will be days of work, to find all software again.

TM backs up and restores files. If a disk drive has directory corruption or develops a bad block that results in some corruption to files prior to a backup, then those corrupted files will be restored as -is, e.g., corrupted files.
There are any number of events that can cause corruption such as momentary power loss, brownouts, or outright power failure, abnormal shutdowns, software glitch or failure, memory glitch or failure, problem on the drive, etc. Some problems are the result of low-level failures while some are the result of high-level failures, and still others the result of hardware failures. Take your pick.
You should try repairing the drive before the extreme of reformatting it:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
If the drive is shown to be OK then you can simply reinstall Snow Leopard. It will not erase the drive and will preserve all your files and data.

  • Time machine does not open after i reinstalled os

    time machine does nlot open.  I reinstalled Lion to see if that was the culprit but nothing happens when I try to start Time mchjione.  Anybody got and ieas about it?

    Please look over Time Machine FAQs & Time Machine Troubleshooting to begin understanding Time Machine.

  • Since installing Lion, I have not been able to utilize Time Machine (does not recognize the back-up drive); my wireless mouse does not function properly; I have experienced unreasonable delays in the system.  Is there a fix or upgrade coming?

    Is there a fix or upgrade to deal with the many problems I am experiencing since I installed Lion?  I can no longer utilize Time Machine (Does not see the back-up drive); my wireless mouse does not work properly; my iMac has slowed down considerably.  I am reminded of having a PC machine again.  Bummer!

    Either downgrade to Snow Leopard or try reinstalling Lion.
    Reinstalling Lion Without the Installer
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alterhatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.)

Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Continue button.
    Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
    Downgrade Lion to Snow Leopard
    1.  Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Quit DU and return to the installer. Install Snow Leopard.
    This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
    If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions.  If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

  • Not a valid photoshop document after time machine recovery and reinstall of photoshop

    After a time machine recovery most of my photoshop documents recovered fine, however there are a select few (and my most recent work unfortuantely) that seem corrupt. It isn't all of my documents. Trying to recover them again from back-up doesn't seem to be working. I did have to reinstall photoshop CS4 after the recovery.
    I have seen similar questions on here but none of the solutions have worked. I've tried opening with other programs, I've tried changing the file extentions etc. If the files were just corrupt recovering them from time machine should fix the problem. Many thanks if you can assist.

    …but it doesn't feel like corrupt files are the problem…
    If it's only a few selected files that are misbehaving but others do open without problems, then you do have file corruption in each of those files.
    Go back in time machine to the earliest possible date after each file was created and restore only that particular version of the file.
    If that doesn't work, then considered the files irretrievably lost.  What kind of error message do they return when you try to open them?
    In any event, it's imperative that you check the SMART status of your drive and Repair Drive (or at least Verify Drive) to check for a failing drive.
    As an aside, taking a belt-and-suspender approach, it's my practice to supplement Time Machine with a clone of my working drive and daily backups of my files.  For some reason, I've had three Time Machine disks fail on three different Macs and locations in the last six months or so. 
    I had Time Machine disabled on all my Macs until I decided to give it one more test run on a 65-lb Mac Pro recently.  I'm not convinced one way or another yet, so all other Macs still have TM disabled for now. Time Machine is very intrusive, and the external TM drives run much, much hotter than external storage files—always a troubling sign in my book.

    Could that read " . . . could not access . . ."?  If so, try repairing your backups, per #A5 in Time Machine - Troubleshooting.
    If not, or if that doesn't help, see #A1 there. Use the TM Buddy widget it details to copy and post the messages here.

    My MacBook Pro recently shut down on me all of a sudden. When I restarted it, it popped up with a gray box with 'OS X Utilities,' then listed various options such as 1. restore from time machine backup, 2. reinstall OS X, 3. get help online and 4. disk utility. what do I do now? I have not backed up to Time Machine in a few days, so I'm not sure I should restore from time machine backup, is there something else I can do? Help!

    Guitar21,
    your MacBook Pro has booted into its Recovery mode. From the OS X Utilities menu, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it get to the login screen now?

  • Time Machine does not show after installing Lion?!

    I upgraded to Lion and now my Time Machine does not work. When I connect the disk it starts and then shuts down. It does not show neither on desktop or on Time Machine. Any ideas. I hate the thought of reinstalling Snow Leopard but...
    Thank you in advance
    Matej

    No reason to reinstall Snow Leopard.
    What's shown on the Time Machine Preferences window for Latest Backup?  If it shows "Error" in red, see #C2 in Time Machine - Troubleshooting.
    If not, a clue may be lurking in your logs.  Use the widget in #A1 of Time Machine - Troubleshooting to display the backup messages from your logs.  Locate the backup in question, then copy and post all the messages here.

  • When time machine does a backup I get an error message

    Added a new Seagate 3T external as a backup drive Every time Time Machine does a backup I get an error message that the disk was not ejected properly, no bid deal just a pain. System 3.5GHz Intel Core i7... 16GB DDR# memory ... OSX 10.8.4.  How do I get rid of this error??

  • Time Machine does not see original backup file on Time Capsuel after reset.

    I recently moved. I have a Time Capsule which is also my airport base station. I have about 7 months worth of back-ups on the drive for an iMac and a MacBook. The local cable company would only hook up the modem directly to my iMac and would not set up through the Time Capsule as it is not one of their routers. No problem. I did it once -- I could do it again. After discovering that it was not as simple as plugging the ethernet cable into the Time Capsule (after doing so, the Time Capsule recognized it had internet feed -- the iMac recognized the Time Capsule/Airport network -- but I could not get onto the net.) I discovered that I needed to do a hard reset. The instructions said the files would not be erased. They were not. I can still see the original back-ups for both computers in finder. But Time Machine does not recognize that either computer was ever backed up. There is no history and when I try a back-up it begins from scratch and creates a brand new back-up file.
    How do I get Time Machine to recognize the original back-up files? I tried "choosing disk" in Time Machine preferences but it only lets me choose the actual disk (the Time Capsule) and not an individual back-up file
    Thanks in advance to the collective brain trust.

    I saw a post on another discussion about this subject, and one user found this workaround:
    2) Start the backup via wireless connection. Stop the backup. Unplug external HD and plug in via USB or FW (you want FW800). Time Machine appears smart enough to continue your backup in a manner that is useable by the AEBS.
    This only makes sense for the first backup (or if you have a lot of data for one particular incremental backup), as it removes the whole convenience factor of wireless.
    The post got this reply:
    Thx for your #2 tip on using Time Machine with an Airport Extreme Base Station, then switching to a wired connection. Worked perfectly.
    Started the TimeMachine b/up wirelessly, allowed it to run for a couple minutes, then stopped it, unplugged the USB drive from the AEBS, plugged it into the computer directly via FW400, opened TimeMachine and it recognized the Disk. Ran TimeMachine via the wired connection, after it finished I ejected it, plugged it back into the AEBS, initiated the AirDisk in the finder, then opened TimeMachine and presto!!
    Awesome tip. Note: this works for first-time TimeMachine wireless backups only. Saved me over 40 hours of wireless waiting!!

    These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad and start typing the name.
    The title of the Console window should be All Messages. If it isn't, select

    In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter the word "Starting" (without the quotes.) You should now see log messages with the words "Starting * backup," where * represents any of the words "automatic," "manual," or "standard."
    Each message in the log begins with the date and time when it was entered. Note the timestamp of the last "Starting" message that corresponds to the beginning of an an abnormal backup. Now
    CLEAR THE WORD "Starting" FROM THE TEXT FIELD
    so that all messages are showing, and scroll back in the log to the time you noted. Select the messages timestamped from then until the end of the backup, or the end of the log if that's not clear. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

  • Time machine does not backup anymore

    Hello all,
    I've been using my time machine for a month now, I kept it turned off and only connected the disk when I wanted to make a backup. Then I just hit Back Up Now from the menu and it always backed up everything (I used to check it afterwards). FYI, I've got a 500GB drive and for backups I use a 500GB partition on an external disk, where about 100GB is still free. All of a sudden, my time machine does not backup anymore. It does its run, whether a scheduled hourly one when turned on, or an on-demand one, but it only lasts a split second as though there is nothing to backup and when I enter the time machine, the files are really missing. I can't make it backup anything anymore. What is going on?
    thanks everyone

    It's not related to this problem, but that may not be large enough. What's important is not the size of your internal HD, but how much is on it (or is expected to be on it in the next year or so). It varies widely, of course, depending on how you use your Mac, but Time Machine usually needs 2-3 times the space of the data it's backing-up.
    . . . it only lasts a split second as though there is nothing to backup and when I enter the time machine, the files are really missing.
    That sounds like the year-old unfixed bug detailed in red in #D5 of [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum).

  • Time Machine does not backup all of my files

    Hi,
    If I compare my Dropbox folder to what Time Machine backups there are differences which means that Time Machine does not backup all files:
    diff <(cd "/Users/phil/Dropbox" && ls -R | sort) <(cd "/Volumes/TimeMachineBackup/Backups.backupdb/Computername/Latest/Macintosh HD/Users/phil/Dropbox" && ls -R | sort)
    There are also differences if I compare my user folder to the Time Machine Backup:
    diff <(cd "/Users/phil/" && ls -R | sort) <(cd "/Volumes/TimeMachineBackup/Backups.backupdb/Computername/Latest/Macintosh HD/Users/phil/" && ls -R | sort)
    I did not exclude the folders affected from the Time Machine backup.
    I have verified this behaviour on other computers as well.
    Does anybody else have this kind of problem?
    Philipp

    These commands solved the problem for now:
    1) Stop the Dropbox desktop application (if needed)
    - Click on the Dropbox icon.
    - Choose Quit/Stop/Exit
    2) Open your Terminal app (Located at /Applications/Utilities/Terminal)
    3) Copy and paste the following lines into the Terminal, one at a time, and press RETURN after each one. PLEASE make sure you copy and paste these commands (don't type them by hand), as getting them wrong could cause some harm. You'll be prompted for your computer user's password (not your Dropbox password) after entering the first command. Keep in mind that the password field in the terminal will remain blank as you type your password. After you type it, just press ENTER.
    sudo chflags -R nouchg ~/Dropbox ~/.dropbox ~/.dropbox-master
    sudo chown "$USER" "$HOME"
    sudo chown -R "$USER" ~/Dropbox ~/.dropbox ~/.dropbox-master
    sudo chmod -RN ~/.dropbox ~/Dropbox ~/.dropbox-master

  • Time Machine does not see my external HD

    I would like to setup TM but it does not see my external HD, but I can see it on desktop in and finder. I can browse it. But time machine does not see it and forces me to use airport time capsule but I don't have it. Help please.

    What format is the external drive in?
    If it's formatted for Windows (either using the MBR partition table or using FAT/NTFS volumes) then Time Machine cannot back up to this disk.
    The disk needs to be formatted as Mac OS X Extended using either the APM or GPT partition tables.
    Life is complicated somewhat by the fact that the OS, in general, can read MBR/FAT drives, but they're not suitable for Time Machine (limitations in the disk formats prevent some of Time Machine's features from working).
    You can check the current partition map/disk format in Disk Utility.app - just select the disk on the left and the information will be displayed below. If the disk is using MBR and/or FAT then you'd need to reformat the drive in order to use it with Time Machine.
