HT3275 Time machine keeps ejecting backup drive

I haven't been able to make a time machine backup in 63 days.  Getting very concerned.  Running OSX 10.8.2.  Time machine spends a lot of time preparing, and after it finally starts making a backup it fails part way through.  I used to be able to make backups just fine using the same external drive.  Verified both backup and Mac disk.  Deleted TimeMachine prefs, re-started....still won't work.  Console only shows these messages for the daemon:

It's a 1 TB drive and my Mac Pro drive is 500Gb.  Time machine is supposed to prune old backup sets as needed to make space.  If you read the messages it appears that it was about to prune some more when the disk got unmounted.

Besides, since when is it okay that Mac OSX spontaneously unmounts an external drive?

  • HT204057 is there a way to use time machine with a backup drive connected to my AirPort?

    is there a way to use time machine with a backup drive connected to my AirPort Extreme?

    Unfortunately, this is not officially supported by Apple......if you still have the 4th Gen AirPort Extreme that you list in your equipment profile.
    However, the new "tower" shaped version of the AirPort Extreme does now officially support Time Machine backups to a drive at the USB port of the device.

  • Can I use Time Machine as a backup drive for my Vista 32 PC?

    I cannot see any of my Mac computers or Time Machine on my network through my Vista PC, even though I have a wireless card in the PC which can connect wirelessly. I have my PC sitting next to my Time Machine that is the hub for my network. I am connected to the internet via ethernet connection daisy chained through my Time Machine which is connected to my cable router.
    I cannot figure out why my PC cannot "see" my Imac, emac, Time Machine, and macbook that are all connected to my wireless network. The PC and Time machine are the only devices with an ethernet wired connection.
    I would like to use the Time Machine's 1 terabyte drive to back-up my Vista PC.

    I would first set up my mac and vista to do simple file sharing and then work my way from there. If you are unable to figure out simple fire sharing i would go look on other forums or advice. Its rather simple to do but it can also cause a lot of headaches. I have wanted to connect my mac and windows server to my network for a while and just recently figured it out.

  • HT3275 TIME MACHINE ERROR: The backup disk image "/Volumes/Data/Sean McGuire's MacBook Pro.sparsebundle" could not be created (error 1).

    I can select a disk (Time Capsule) and initiate the backup.  It only "waits to back up" then "making backup disk available" and remains frozen there.  I tried to update the software a while back and was unsuccessful, I think that may be the issue.
    Any insight would be greatly appreciated.  This is the error message I receive.

  • HT3275 Time Machine Performs Partial Backup

    I am using the Time Capsule as my backup drive. It stopped backing up about 3 weeks ago (returns immediately to the "waiting to backup" state). I deleted my hard drive image on the time capsule, and it backs up about 25 GB before going to "waiting to back up" again. Further attempts to backup show only about 300 MB of progress before it goes back to "waiting." I've tried partitioning, rebooting... pretty much everything I've found online so far. Everything leads to the same result: a partial backup of about 25 GB.
    Anybody had this problem before?

    It is likely something is corrupted.
    How old is the TC?
    Load the widget so you can find log messages from TM to find out what is happening.. TM doesn't always give rational explanations.
    A1 http://pondini.org/TM/Troubleshooting.html
    Also try a reset of TM.. A4 and certainly a drive verify. A5.
    Did you upgrade or clean install ML onto the Laptop??
    Wireless is a real issue if you upgrade installed.
    Try doing the backup by ethernet.
    Make sure the TC is not in Join a wireless network mode otherwise that won't work. But you should if all else fails extract the TC from the network.. do a full reset and try again completely isolated by ethernet only. When you do this turn off wireless so only ethernet is working.

  • I need to reinstall OS X, will Time Machine recognise my backup drive?

    Due to permissions problems I need to reinstall my OS. Will my backup drive still be recognised by my MacBook Pro after a fresh install? Also will the permissions problems simply still be there if I restore using Time Machine?

    Most or all aren't really a problem. Why they keep being reported is a mystery, but they're innocuous.
    Here's the scoop: http://support.apple.com/kb/TS1448
    I have booted from my install disk and repaired permissions.
    Not necessary. Use Disk Utility in your Applications/Utilities folder.
    The reason I checked permissions in the first place was because a program was not opening (Limewire). The dock icon would bounce once then nothing.
    You need to find out why that is. Reinstalling your entire OS is vast overkill, and probably won't help anyway. The simplest solution might be to re-download and reinstall it. If that doesn't help, your best bet might be to first search for Limewire in the +Using Leopard+ forum to see if anybody else has had the same problem. If not, post it there, with as much detail as you can.
    Anti virus software shows no viruses
    There are no Mac viruses. None. Most Mac users don't run any anti-virus software. Most of the anti-virus software, especially the stuff you pay for, is worse than a virus!
    Some folks do run it, to keep from passing Windoze viruses they might get on to their PC friends. The free ClamXav is most often recommended here by those who know about such things, and they say it's the least obnoxious. Do a search for virus in the +Using Leopard+ forum, and read some of the many threads.

  • Time Machine for 2 backup drives

    I want to back up to 2 externals. I understand this can be done now.
    <Subject Edited by Host>

    Yes you can use as many external drive as you like to make Time Machine backups to. But you can only do one at a time, then disconnect that drive and connect another and then select that other drive as the Time Machine backup drive. Then you can do another full or partial TM backup to that other drive. But the next time you connect the original TM backup drive you will again need to Select it AS the TM Backup drive. It will then pickup the original backups you have made to it and backup changed files to it. Then you can disconnect it, reconnect the second drive and again SELECT that drive as the TM Backup drive.
    You can do that as many time as you like to as many external drives as you like, 2-4-10 whatever number of externals. But you will need to Re-Select that newly connected drive AS the TM backup drive. TM only keeps a record of the Last Drive used. Not s series of drives used.

  • Time machine keeps preparing backup..

    Hi, my Time Machine linked to a 1TB Time Capsule keeps preparing the backup but no backups are done.
    I had a look at the 'backupd' in the console messages and here is what i have:
    26/07/2009 22:11:13 /System/Library/CoreServices/backupd[214] Disk image /Volumes/Data/The MacBook_0023df8ceb34.sparsebundle mounted at: /Volumes/Backup of The MacBook

    26/07/2009 22:11:51 /System/Library/CoreServices/backupd[214] Node requires deep traversal:/ reason:kFSEDBEventFlagMustScanSubDirs|kFSEDBEventFlagReasonEventDBUntrustable|
    Anyone could translate this for me?
    Thanks,
    S.

    Hi thezedhongkong,
    My understanding of the "node requires deep traversal" is one of a few things:
    The "backupd" process has lost track of what's contained in your backup and how much has changed since the last backup. As a result it needs to verify the integrity of the sparsebundle image, unpack it, check each file against what's on your machine currently and then run the backup again.
    Every file has a "flag" that the backupd file is looking for when it scans the drive. If the flag is "on" then that means the file has changed since the last backup. If the flag is "off" then that means the file has not changed since the last backup.
    Flag On - Backup
    Flag Off - Don't backup
    It's why Apple recommends against backing up large database files. Because if one piece of information is changed the entire database file will need to be backed up every single time. Entourage and Aperture are common offenders of this issue, iPhoto is not because it's a package (a gloried zip archive).
    Based on how large the sparsebundle is, I've seen deep traversals take as little as 1 hour to as long as 8 hours (I had a 178GB image). Unfortunately, if you stop/cancel/quit the process it has to start over again each time. So you pretty much just need to let it sit and do its thing, even if that means overnight.
    Now my understanding of the entire process could be totally wrong, so someone please correct me if that's the case.

  • What happens to Time Machine if my backup drive isn't connected?

    I've got Time Machine set up to back up a MacOS Leopard Macbook to an external drive. Because of the way this computer is used, it's usually not plugged into the backup drive.
    What does Time Machine do in this situation? Does it keep track of all the changes since it last saw the backup drive, or does it only keep one increment between the last backup and the current one? Does it still automatically back up, or do I have to prompt it?
    I understand that Lion has a feature that keeps local backups until it sees the backup drive again, but it's not clear to me (because Apple updates the Time Machine support documents to reflect only the latest version of the OS...) whether something like this happens in Leopard.

    Time machine will recommence back ups from the last point backed up.

    It should scan and pick up alterations to previous back ups as a matter of course.
    For all matters dealing with Time machine Google 'Pondini' and a variety of options about it will appear.

  • HT3275 time machine states: the backup is too large for the backup disk?? not sure what to do here,

    does anyone know what to do here?? time machine will not complete any backups- every time it attempts it states the backup disk is not large enough

    If you decide to erase the Time Capsule and start over with a new set of Time Machine backups.....
    Open Macintosh HD > Applications > Utilities > AirPort Utility
    Click on the Time Capsule icon, then click Edit
    Click the Disks tab at the top of the window
    Click Erase Disk
    The Quick Erase option will only take a few minutes
    Once the procedure is complete, close AirPort Utility
    To start over with a new set of Time Machine backups.....
    Click the Time Machine clock icon at the top of the Macs screen
    Click Open Time Machine Preferences
    Make sure Time Machine is On
    Click Add or Remove Disks
    Click your Time Capsule
    Click Use Disk
    A new backup should start in a few moments. Allow plenty of time for the first backup because the entire contents of your Mac will be copied over on this backup.
    If you want to keep your current backup history and add a new Time Capsule, we'll need to understand how you have your Time Capsule set up in your network at the present time.
    Is the Time Capsule now connected to a modem with a wired Ethernet cable?
    What is the make and model number of the modem?
    Does the Time Capsule provide your wireless network signal, or does another modem/router perform this service?

  • Time Machine Keeps Selecting Different Drive After Restart

    Here is my situation, which is a bit different from most people's I think:
    I have a Mac Pro running 10.5.5 with 4 internal hard drives: 250GB Original, 750GB, 750GB, and a 500GB. I also have a MacBook. I used to have things setup so that my iTunes for the Macbook was stored over the network on a 750GB drive, and the Mac Pro AND the Macbook had their Time Machine files on the 500GB.
    Then I switched things around so that the iTunes is now on the 500GB and the Time Machine is on a 750GB. I used "restore" in disk utility to copy over the Time Machine files (although this worked it could only be done a specific way after much trial and error - ask for details if interested). It worked, and the Mac Pro backs up flawlessly right where it left off on the new drive.
    The Macbook WILL find and load the old sparse file from its new location. But I have to manually select it EVERY TIME. The problem is that despite the fact that I completely erased the 500GB drive first, it stills defaults to that drive for TM. AND this is AFTER I have thrown out the time machine preferences from the library. It will work fine for infinite backups as long as I don't shut down the computer. As soon as I restart, it defaults back to the other drive and I have to repeat that cycle all over again of throwing out the preferences, changing the TM disk, and it is never easy to get it to "see" the drive I want...etc.
    Any thoughts much appreciated!

    Glenn,
    Thanks so much for your reply. Unfortunately that did not work. As soon as I connect to my iTunes drive, I can see the name of the backups volume change in the TM preferences pane from "backups" (what it should be) to "music."
    In the interest of presenting as much info as possible, I will add that I always have to select my iTunes folder before opening the Itunes app. I had it set up before (when drives were reversed) so that my "music" volume would open as a login item, since I was tired of doing it manually every time. The TM just mounted normally whenever it needed to. It worked perfectly. I thought that maybe I could fix this current problem by having BOTH my music and backups volumes mount at startup. Interestingly, even if I select them both, the mac will only mount one or the other, not both - in fact one of the drives disappears from the accounts>login items pane after startup as if I had never put it there! It CAN mount two drives though if I select another, third drive that I also have shared that is neither for music or backups. Just not THESE two. I am at a loss....I am pretty sure I erased these drives before making the switch - I know one of them I even wrote to zeros.... Thanks again.

  • Time Machine icon on backup drive is missing

    I just got a new external backup drive to replace my old one that was full. Once mounted on the desktop the drive icon had the well known orange icon with the FireWire symbol on it.
    After my first backup to the new drive I expected it to get the Time Machine icon automatically, but this did not happen. My old Time Machine backup drive had the green Time Machine icon on it with the arrow.
    Can anyone tell me why this did not happen with the new drive, and how I can get the time Machine icon attached to the drive. I would like to have that icon attached to the backup drive so I can differentiate that drive from two other external drives I use for other purposes.

    Addition to my above post:
    When I mount my previous backup drive, and choose this drive in the Time Machine preference pane of System Preferences under Change Disk, it still does have the Time Machine icon. But the new drive does not have this icon.

  • Time machine keeps repeating backup of entire iMac harddrive

    Two issues with Time Machine:
    ISSUE ONE: Time Machine is backing up my ENTIRE hard drive, which takes several hours, every time it automatically backs up which is often - not just the changes that are due to me working on the computer and editing existing files or creating new files. I want Time Machine to only update the changes as per the description of how this software is supposed to function as provided by Apple.
    ISSUE TWO: I excluded some files from the backup to reduce the volume that was being frequently backed up, assuming I had the option to return them to the list of files to be backed up but it seems I cannot do so. You can only exclude files from the backup and not reverse this action which doesn't make sense at all.
    I would like to resolve both issues.

    Hi, and welcome to the forums.
    Both problems may be caused by the preference file being corrupted. Try a "full reset" of Time Machine, per #A4 in Time Machine - Troubleshooting (or use the link in *User Tips* at the top of this forum).
    If that doesn't stop the full backups, is your entire system being backed-up each time, or only your home folder? If in doubt, create another one via +System Preferences > Accounts+ and see if it's affected, too.

Maybe you are looking for
