Time Machine Error, backup disk couldn't be mount

I have a USB drive plug to my Airport Extreme and I use it for Time Machine. Today I had a message saying: "Latest Backup:Failed"
Time Machine Error
The Backup disk image could not be mounted.
The hard disk is there, I can drag, drop, copy, delete files on that disk. There's is a big file call Serge'siMac_001ec205f583.sparsebundle, the file does not seem corrupted, I could probably drag it to the Desktop. How can I mount the backup disk.

  • Time Machine error: backup disk image could not be created

    Iet up my new time capsule day and it's working great. Now that I've got everything sorted out, I'm ready to do the initial time machine back up on it. I went into preferences, changed the backup location to my TC and clicked 'back up now'. Very quickly I get a message that the backup failed: "Time Machine Error - The backup disk image could not be created".
    I've searched the apple support area but haven't been able to figure this one out. Can anyone help, please? This is an initial backup. (FYI, it worked great on my old external drive.)
    Many thanks

    I had the same problem. I installed my Time Capsule, fired up Time Machine and got an error that said "The backup is too large for the backup volume. The backup requires 436.8 GB but only 182.2GB are available."
    Coincidently, these are the same sizes as the space used and the space available on my iMac's drive.
    I looked in /Volumes and saw that the sparsebundle was being created on the local disk and not on the main disk. Trying to backup again gave me the "Time Machine error: backup disk image could not be created." message.
    I poked around the forums, and found a post about the machine name setting in sharing. I decided to give it a look, and lo and behold, I did not have a machine name. So I gave my box a name, kicked off Time Machine again, and it worked.

  • HT3275 Time machine error, backup disk image "/volumes/data-1/.sparesbundle " already in use. I don;t know what this means, can someone help?

    My Mac mini time capsule is showing an error Time machine error, backup disk image "/volumes/data-1/.sparesbundle " already in use. I don;t know what this means, can someone help?

    I had a similar problem and I solved it as follows -
    In Time Machine - > I deselected time capsule Data Disk as a destination.
    Then I pulled the power plug on the Time Capsule, twiddled my thumbs for 15 secs, plugged the power back in.
    Went back t Time Machine -> Re-Added the Time Capsule Data Disk as destination. And then tested by selecting Backup Now.
    All went well and the backup picked up from before the problem.
    BTW - I also have a USB drive connected to Time Capsule that is an alternate disk for Time Machine to backup.
    In Mountain Lion the GUI lets you add more than one Time Machine backup destinations very easily so I think it a good idea to have redundancy.
    Hope this helps.

  • "Time machine error, The disk image cannot be mounted" What can I do??

    I ran the time machine. Then, "preparing backup" showed up for a long time. After that, a window pop out: "Time machine error, The disk image cannot be mounted" What is disk image? What can I do (I can't back up anything)
    P.S. I use time capsule for backup. there were no problem on connection

    I'm having the same issue. I do not have TC as my base station. It says right in the book that if you choose, you do not have to have it run as your router, just as a part of your existing wireless network. All software is up to date and I have already shortened the name of both my TC and TC disc to 6 characters and no spaces! I've already spoken with someone today about this. He really didn't know. Have tried backing up both wirelessly and directly connecting with an Ethernet cord. I had to finally call because when I attempted to register the product to get online support, apple.com didn't recognize the serial number!!! The gentleman on the phone got it registered for me. I bought the TC from an official apple store and for whatever reason when he put in the serial number his computer said that this TC was so "old" I guess that there was technically "no support." That basically means that even though my parents just purchased this for me a week before Christmas, that it was made a year ago and the warranty is not good?? I need to do more research on that. Right now I am very unhappy about this. I am a firm apple user and have been for years, but this is frustrating.
    I had read somewhere else (not sure I've been searching apple for what seems like forever now) to make sure that the TC was showing up in "devices" of the Finder. Mine doesn't show up there, but rather in the "Network" window. Is this an issue? If it is, can anyone tell me how to fix that. I have Time Machine backing up to my TC, so I do not see why it would be.
    UPDATE: I just opened up my TC on the "Shared" section of the Finder window and deleted the old "sparsebundle" (I had no clue that anything had backed up way back at 3:30pm on Dec 29) and now I get a slightly new message: Time Machine Error: The backup disc image could not be created." So now the word "mounted" is replaced with "created." This error showed up a lot sooner than the original one. Ok, no clue. I am going to try to Change the Disc again, and try again. I will post another update.

  • Time Machine Error: Backup Disk Image Could Not Be Mounted

    Time Machine was working just fine with Time Capsule for the first two days, then today I got the above error message.
    The drive and the backup image both show up in Finder. I can even copy files from the Time Capsule to my hard drive.
    I just can't get Time Machine to backup to the Time Capsule, even if I manually hit "Back up now".
    Any ideas what I can do to fix this?

    I may have fixed this ... I renamed my TC to a shorter name with no space and no apostrophe - just a few letters. That seems to have cleared it up - at least for now. Time will tell ...

  • HT201250 Time Machine error - backup disk is not available

    A new external USB disk was installed and fromatted as per apple and manufacturer instructions. Time machine backup was initated but had to be stopped after 2-3 hours. Upon resuming using "backup now" function an error message reported - Time machine could not complete the backup. The backup dis is not available.

    Never mind, I fixed the problem by removing a lock feature from my external drive.

    Often, this error can be corrected by pulling the power on the Time Capsule, waiting a few minutes, and powering the Time Capsule back up.

  • Time Capsule - Time machine error "backup disk image could not be mounted"

    Recently I lost a folder and attempted to resore from my Time Capsule backup (which I started when it first shipped) not only did it fail, but know I get the message "backup disk image could not be mounted" when I try to backup. I have used Airport Utility to try and sort - that shows green light and it is connected by ethernet 9and shows in network (I can see the sparsebundle). I have been trying for a couple of weeks now - any ideas??

    John & Joel,
    I've done some research and put together some ideas.
    "The backup disk image could not be mounted"
    *“Disconnect All Users…”:*
    If your Time Machine backup drive (“Backup of Users Computer”) is mounted on your desktop or in the Sidebar of the Finder window. then Time Machine may think the drive is already in use. Alternatively, if the Time Capsule hard disk has been recently accessed by a Windows machine, it may not have fully relinquished control. Do the following:
    Open Airport Utility and select the Time Capsule on the left.
    Click “Manual Setup”.
    Select “Disks” at top of window.
    Click “Disconnect All Users…” at bottom of window.
    Now try Backing up again.
    *Stalled .inProgress Files:*
    Select the TC in the SideBar of the Finder window.
    Click "Connect as...". Enter your TCs password.
    Double click the blue folder that appears in the finder window. The sparsebundle should now be visible.
    Double click the sparsebundle and then click “Skip” in the checksum message.
    Once “Backup of (Users Computer)” mounts in the Sidebar open the folder containing past backups. Are there any “.inProgress” files there. Delete them.
    Unmount the backup drive and try backing up again.
    *Permissions Issue:*
    Select the TC in the SideBar of the Finder window.
    Click "Connect as...". Enter your TCs password.
    Double click the blue folder that appears in the finder window. The sparsebundle should now be visible.
    Highlight the sparsebundle and “Get Info” (Cmd-I). At the bottom of the Get Info window open the “Sharing & Permission” section. Beside “Everyone” it should say “Read & Write”. If it does not, change it.
    Now try performing a backup again.

    If that is the case simply reboot the TC.. or if that fails, reboot the whole network, restarting in correct order..

  • Time Machine:The backup disk ran out of space unexpectedly. .....

    Hi,
    I upgraded to Mountain Lion when it was released and yesterday I began getting this notice from Time Machine:
    "The backup disk ran out of space unexpectedly. Time Machine will try to make more space available by removing expired backups during the next scheduled backup."
    I have a one terra external hard drive with exclusively Time Machine.  It says it has 3.4 gigabytes available, but isn't deleting old backups and making room for new, like before.  I tried the "encrypting" solution, but it still keeps on giving me this message.  Should I erase and format?  If so, what option should I chose to format?
    My Hard Drive has 240 gigabytes, so 1Tb should be more than enough.
    Thank you!
    Gloria

    SuperDuper and Time Machine are two completely different backup utilities. If you want something like what SuperDuper does then don't use Time Machine. You have many other options that won't use up all the space on your backup drive:
    Backup Software Recommendations
    Carbon Copy Cloner
    Data Backup
    Deja Vu
    SuperDuper!
    Synk Pro
    Tri-Backup
    Others may be found at VersionTracker or MacUpdate.
    Visit The XLab FAQs and read the FAQ on backup and restore.  Also read How to Back Up and Restore Your Files.
    Do the following to erase your drive:
    Erase a Drive
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. 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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.

  • Why is Time machine saying backup disk disconnected? Using MBP 17" Lion 10.7

    Why is Time machine saying backup disk disconnected? Using MBP 17" Lion 10.7

    Do you have an external drive connected?
    If you do has it gone into sleep mode? There is a setting in the OS to put drives to sleep if they aren't being used. Energy Saver "Put the hard disk to sleep when possible".
    Also most external drives have a built in sleep function that if they aren't being accessed for a period of time they go to sleep by themselves.

  • Time Machine / Time Capsule Error: Backup disk image could not be mounted

    So I'm trying to back up to time machine, which used to be working fine, but I have this problem happening on two computers now (which probably means the error is in my Time Capsule.)
    The Time Capsule shows up on my "shared" list in my finder windows.
    I can connect to it, and open the folder inside, and SEE my two disk image files in there.
    But Time Machine gives me a "The Backup Disk Image Could Not Be Mounted" error. No other information.
    If I double-click on the disk image file directly, I get an error "The Following disk images failed to mount" and then it lists the file and says "Resource temporarily unavailable."
    Help, please.

    I'm caught in the same loop, with no end in sight. I've only been using Time Machine and Time Capsule for 2 months. This week it stopped working. First error message:
    "Unable to complete backup. An error occurred while copying files to the backup volume."
    Checking the Time Machine preferences, "Last backup" would read "backup failed"
    When I got this error, all the wireless functions went offline, even thought the TC light was still green.
    I would shut down, shut down the Time Capsule, shut off my modem reboot everything in order.
    Next error message:
    "Disk repair. The disk 'Backup of [my computer]' was not repairable by this computer. It is being made available to you with limited functionality. You must backup your data and reformat the drive."
    Then: "Time Machine Error: The backup volume is read only. To select a different volume ... Time Machine preferences ... "
    I spoke to someone at Apple, who sent me the Time Machine Troubleshooting page:
    http://support.apple.com/kb/HT3275?viewlocale=en_US
    I went through:
    1. updated my system software
    2. updated the TC firmware to 7.4.1
    3. dragged the sparsebundle to DiskUtility. It took a while (more than an hour?) but said the disk could not be repaired. When I tried again, the repair function wouldn't run.
    4. tried to delete the sparsebundle, but it would choke at almost the end, sometimes it would just crash the finder, sometimes say "Sorry, an unexpected error occurred," sometimes "Operation cannot be completed because the item 'bands' is in use." I even tried to Stuff the bundle with 'delete original' checked, but the stuffing, after about 15 hours, jammed near the end (stuffed 20 gigs of 35 gigs).
    5. tried to reselect the TC, and run backup anyways ... now it can't find the volume, back to the error messages and crashing Finder
    6. checked password in Keychain, all ok.
    Now what??
    Do I use Airport Utility to erase it? At least TC is still showing up there. Or press the rest button on the back of the Time Capsule to reset to factory defaults?
    I've resigned myself to losing my backups. Now I would just like to get it up and running again.
    In hopes,
    Linda

  • Time Machine thinks backup disk is full but its not

    I just purchased a new 1 Terabyte hard drive for backup. In the past I backed up both my internal Mac harddrive (250 Gb with 8gb free) and an external iOmega archive drive (DRIVE H 320Gb with 41Gb free) to a 500Gb Lacie drive. I purchased an iOmega 1 Terabyte drive (DRIVE G) because the Lacie drive was full. I went into Time Machine and changed the backup drive to the G one terabyte drive and did a full backup of my internal hard drive. When I did this I did not have the external H archive drive attached so Time Machine didn't back that up. I did it that way because I wanted to first backup the internal drive then do some work and then go backup the external archive drive over night. I plugged the H archive drive in, so it show up in the finder and then told Time Machine to Backup Now. It started the back up but right after doing the initial computations when it actually started backing up I got the standard error message that "the backup disk ran out of space unexpectedly..."  I've double checked that the backup disk is set correctly in Time Machine to the 1Tb G drive and when I do a Get Info on the G drive it shows Capacity: 1TB, Available: 713.54 GB.
    Is it possible something is wrong with the new drive? Can I test that?

    Its funny how sometimes asking a question can prompt  your thinking. As soon as I finished posting this I thought "of course Disk Utility".  I ran a check disk and got the following error message:
    Unused node is not erased (node = 107)
    I did a restore which corrected the error. Turned Time Machine back on and its backing up the rest of my data now.

  • Time Machine Error - Backup Requires 2,211,365.5 GB!

    Hello - I have searched the posts and nothing seems to touch on this specifically - I have been using Time Machine successfully for months and this has only started to happen in the last few days.
    I have a white Macbook, 10.5.6 with an upgraded 150GB hard drive. I do backups sporadically (once or twice a week), as I don't want to keep my Macbook connected to a hard drive and I find using the airdisk feature on my AEBS takes too long and slows down the network. This has been working fine for me for months, but now I get the following message:
    Time Machine Error
    This backup is too large for the backup volume. The backup requires 2211365.5 GB but only 125.5 GB are available.
    I tried reformatting my disk (250GB hard drive) and the problem still arises. There are no external drives or anything connected to the Macbook at the time.
    Can anyone help? I don't want to go out and buy a Hard Drive with a 3million GB capacity!
    Thanks
    Ian

    If TM is seeing a ridiculous amount of info to backup like that (2 million gigs is probably not a real number I am guessing) it probably means you have file structure problems that are causing TM to count a folder infinitely in some kind of loop... like maybe a file link to itself that kind of thing.
    A disk check usually repairs these sorts of problems and should alleviate your issue.
    I believe you are correct and I would add that this case might require stronger medicine such as DiskWarrior to repair the directory structure, if that it the issue.

  • Time machine - "the backup disk image could not be mounted"

    SInce a few days, I am unable to backup via Time Machine.
    I always get the message:
    TIME MACHINE ERROR
    The backup disk image could not be mounted
    I use an Apple Time Capsule and still have more than enough free space on it.
    Use OS X 10.5.5
    Help.....
    Tks

    Rosy,
    *_"The Backup Disk Image Could Not Be Mounted" (Console - “Failed to mount disk image”)_*
    First, it is important to distinguish this error message from another, similar Time Machine error that states “The backup volume could not be mounted”. This is important as the causes and cures for these two errors can be very different.
    Consider each topic below separately. When one option does not resolve your issue, then move on the next one.
    *Unmount the Backup Disk Image* (TC)
    If, for some reason, you have manually mounted the Time Machine backup disk image (sparsebundle), or Time Machine failed to eject it after the previous backup, subsequent backups may fail. (Console - “Failed to mount disk image”… “Backup failed with error: 21”)
    Eject the backup disk image (white drive icon) by either clicking the little Eject icon to the right of the disk image in the Finders’ Sidebar, or Ctrl-Click the drive icon on the desktop and select “Eject” from the contextual menu. Now try backing up again or launching Time Machine to view previous backups.
    *“Disconnect All Users…”:*
    If your Time Machine backup drive (“Backup of Users Computer”) is mounted on your desktop or in the Sidebar of the Finder window. then Time Machine may think the drive is already in use. Alternatively, if the Time Capsule hard disk has been recently accessed by a Windows machine, it may not have fully relinquished control. Do the following:
    Open Airport Utility and select the Time Capsule on the left.
    Click “Manual Setup”.
    Select “Disks” at top of window.
    Click “Disconnect All Users…” at bottom of window.
    Close the Airport Utility.
    Now try Backing up again.
    “I got it resolved. Apparently it had to do with one of the files being open on the disk from the drive. I had browsed the disk with one of my windows boxes here and it must have left one of the folders "open". Anyway, I rebooted the TC and we are good to go now.”
    *Proper Computer Name* #
    Make sure your computer has a proper name. Go to System Preferences --> Sharing. Time Machine needs to differentiate your computer from others on your network (i.e. "Bills MacBook" or "Office iMac"). If the "Computer Name" field is blank, create a name. Realize that if this step is necessary, you will likely have to start the Time Machine backup process over again and do another full initial backup.
    According to this article, [http://support.apple.com/kb/TS1760], Time Machine may experience problems if your computer name includes certain characters. Make sure the computer name only includes ASCII characters from the following set.
    (0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ)
    Once a change in the computer name occurs, you should stop and restart Sharing on the affected computer. Uncheck and then recheck Sharing in the Services list on the left.
    Let us know if any of the suggestions above resolves your issue.
    Cheers!
