Time capsule not backing up my iMac

Apple replaced my Time capsule with a new one. Old one backed up 2 x macbooks and my iMac. The new one, whilst backed up the two mac books as before, tells me on my iMac that: Time Machine could not complete back up becuase there is a problem with my username or password. I put in the password - same as used on the macbooks, it accepts it, but then tells me the back up has failed again. Round and round we go. Any assistance would be greatly appreciated!

    Yes, if you use an application like Genie Timeline Pro, which was designed for this type of purpose.  Genie Timeline will make a complete copy of your Dell on the first backup. After that, it will only backup the changes that have occurred since the last backup.

  • Time Capsule not backing up after 1.5 years

    Can someone help with this message? I am running time machine to back up my imac and MacBoo Pro also. imac is running snow leopard and macbookpro is running mt lion. "This backup is to large for the backup disk. the backup requires 12.58 GB but only 596.8MG are avaliable.  Time Machine needs work space on teh backup disk, in addition to the space required to sotre backups. Open time machine preferences to select a larger backup disk or make the backup smaller by exluding files.

    squkid,
    we could run a number of test what has gone wrong, however the quickest and safest way to make it all work again is to redo the backups.
    This is a very good article by one of senior members of this forum which explains how to go about things step by step.
    http://pondini.org/TM/Time_Capsule.html
    I suggest you do as per Q5 and erase the whole set of backups and start over.
    If you work over WiFi it is a good practice to do the first initial backups of your iMac and MBP on the cable connection to the Time Capsule. This will save time.
    Then the incremental backups can go over WiFi.
    Post if you have further problems.

  • HT1175 3TB time capsule not working with new iMac

    I have a 3TB time capsule that's c. 2 years old. It worked perfectly with my old iMac. I bought a new 27" one when it came out this year and since the time capsule will not work.
    I had to clear all the data as a starter. Now it gets a little into the backup taking c. 1 day then resets. It's connected via ethernet cable and has been told to join an existing network.
    Currently it says it's backing up 922,498 items, after 2 hours (this is the third attempt, it resets then has no record of the old backup) it says 10kb of 789.44 GB - About 4,664,440 days remaining!!
    To clarify I'm trying to use Time Machine with the Time Capsule.
    Please help!!

    You have made a mistake in the setup.
    You do not "Join an existing networking" and use ethernet.. they are mutually exclusive.
    What you are doing is backing up over double hop wireless which is slowing to a crawl.
    You need to put the TC into bridge mode.. and plug it into the main router by ethernet. Then use wiretess to the TC if you are too far away or ethernet if you are close by..
    As soon as you put the TC into join a wireless network it deactivates the ethernet.

  • Time Machine and Time Capsule not backing up

    I could really use some help please.  A little while ago I could back up to my Time Capsule via Time Machine.  Then it became slow.  Then it decided that it couldn't find the backup disk.  After 1-2 hours of waiting, then I couldn't stop the backup even when it wasn't backing up, other than via Activity Monitor. 
    I have tried suggestions offered such as:
    Deleting the, com.apple.TimeMachine.plist (although not the one below it, i.e. com.apple.TimeMachine.plist.lockfile)
    Stopping backup via Activity monitoring
    Resetting Time Capsule
    Powering down and back on again - everything
    Starting in safe mode and restart etc.
    I am at a loss to back up my data.  Yet more hours lost trying to resolve this situation.  Shouldn't back via Time Machine just work??
    I see my Time Capsule as connected in Finder.
    I finally got to the point of, "I don't belive this", when Safari didn't function correctly, Activity Monitor didn't open.
    My operating system is Lion 10.7.5 on my iMac.  I have got Filevault enabled.  I am using Parallels 7.
    Any ideas that work, greatly appreciated.
    Thank you

  • HT3275 Time Machine Error (Time Capsule) - Not backing up "problem may be temporary"

    Hi,
    I am running Time Machine backing up to a Time Capsule (2TB version).
    Since yesterday the backups have not performed as scheduled, with a vague error saying files were not copied and this may be temporary.
    The Time Capsule software is up to date, I've unplugged it and plugged it back in, and have restarted the mac (twice!).
    Still getting the error - it suggests I repair the backup disk in Disk Utility but it is not displayed in Disk Utility so not sure how to do that.
    How temporary is temporary and what can I do to repair the disk if it isn't showing in Disk Utility?
    Cheers.

    Welcome to Lion.. did you just update again to 7.4.. no doubt some new bugs will now flow into the network.
    You need to firstly download and use utility 5.6 as the version in lion is useless.
    http://support.apple.com/kb/DL1482
    If the TC will not be recognised you need to plug into it by ethernet.. I guess you are using wireless.. even worse on Lion.. and press the reset and redo the setup. Lion has no idea what went before, only what comes after.
    To verify the disk you need to mount the sparsebundle.. but to do that you need to see it which means direct connection and reset.
    See http://pondini.org/TM/Troubleshooting.html
    A5 how to verify.. but frankly I doubt it has anything to do with it.

  • Time Capsule not backing up every hour

    It seems that my time machine has a mind of it's own and backs up almost anytime it wants to. An example would be 4 backups in the same hour. thanks for your help!

    Reset Time Machine as follows:
    Open System Preferences and open Time Machine
    Click Change Disk
    Click your Time Capsule to highlight it
    Click Use for Backups
    Normally backups will start up again automatically after 30-60 minutes. If not, click the clock shaped Time Capsule icon at the top of your screen to manually start backups again.
    See if that helps. Do you have any applications like Entourage, Aperture, VM Fusion or Parallels on your computer? These and other files like them have a "monolithic" file structure. What this means is that any change made to the program will result in the entire database being backed up.
    For example, if you are using Entourage and make only one small change to an email, the entire database will be backed up. This takes up a lot of space on your backup drive, not to mention time.

  • Time Capsule not visible to my iMac (Yosemite 10.10)

    Having given up on trying to access my TC via a BT HomeHub4 router, I've plugged it in via Ethernet to my iMac.  No other devices on the iMac.  iMac is connecting fine to internet via the HH4.  Despite this, I still can't access the TC.  Here's what I've tried:
    TC is flashing amber status.
    Open the Time Machine tab in System Preferences.  Made sure it is set to 'On'. Pressed 'Select Backup Disk'. Get a 'Other AirPort Time Capsule' icon, which I select.
    Click 'Setup".
    New window with a globe icon for the internet with a green status light.  Top left there is an 'Other Wifi Devices (1)' button, which I press - no other option.
    This gives me a new list, the only not-greyed out option is my TC (I know it's mine because the name is right).
    Select it and get a 'Gathering Information about your network' message, icon for the TC and a spinning wheel saying 'joining Airport TC....'.
    Eventually it gives up and shows an error message 'An unexpected error occurred.  Try again.'
    Trying again doesn't help.
    I've reset the TC with a biro - pressing for one second, pressing for 5 seconds (for a fast flashing amber) and pressing while powering the TC on. 
    None of the above works.
    Any ideas?  I don't know if it is connected to Yosemite?

    I do not have yosemite installed on any computer.. I am getting old you see and spent my youth on the bleeding edge.. so that I have now too little blood left for installing latest greatest OS until you beta testers are finished.
    So here are the lessons from Mavericks.. and all the ones that go before.. Take it if you wish.
    Do the setup in full internet isolation.. turn off wireless and use only ethernet to the TC LAN port.
    1. Factory reset the TC. (Again).
    2. Make sure IPv6 is set to link-local only in the ethernet settings on the computer.. I am guessing this option is still available.
    Note that the IP addresses must all be as shown.. The TC reset is 10.0.1.1 and the computer should be 10.0.1.2 although that is not a major one.. but if you use dhcp that should be correct.
    3. Open the airport utility and do a manual setup.
    Again I am making assumptions that the airport is there. And these options but I doubt it will have changed much.
    4. Type in the IP address and proceed.. password should not be needed but is public.
    5. Should now get the full summary page.. and you can do a full clean setup without the wizard bothering you.
    Go to the base station tab and name it.. TCgen4 (for example) all names should be short no spaces and pure alphanumeric.
    Go to the wireless and create a wireless network.. eg TCwifi
    Set security to WPA2 personal with all alphanumeric password..
    Go to network tab and make sure it is set to bridge.
    Now update the TC.
    Plug it into the HH by ethernet to its WAN port.
    5. In finder use top menu, go, connect to server and force it to AFP.
    AFP://TCgen4.local (or use whatever name you have in place of my suggestion).
    You should be asked for a password.. we did not change it so it is still public. For now stick to default.
    Does it mount?
    Do any of the functions i have listed no longer exist in Yosemite?
    I hope that all the pictures display as we have issues with apple site dropping the pictures out.. tell me if you cannot see them.

  • Time Capsule not backing up -  Most of storage space used.

    I have a a 1TB time Capsule that only has 50.0 GB left. It has worked fine until of late. It now will not back up no matter how small I make the file to backup. It tells me backup disk image could not be mounted. It was giving me another error message until I lowered the file size to backup. Suggestions and also is there a way to delete Time Machine usage space (not other files) from Time Capsule. Guessing that it is not deleting to make room for more. Help.

    Sorry to hear that you are having problems. Before you think seriously about erasing the Time Capsule, it would be a good idea to make sure that it will have adequate space to backup your computer(s) and leave plenty of space for incremental backups.
    Right click your Hard Drive icon and select Get Info to get the specifics for each of your computers. The general rule of thumb is that your Time Capsule should have enough space to backup both computers and another half of the space will still be available for backups. For example, your two computers have a total of 250Gigs stored, so you would need a minimum of a 500Gig Time Capsule.
    If you decide to erase the Time Capsule, open AirPort Utility. Click on Manual Setup, then click on the Disk icon at the top of pane. Then click on Disk just below the icons and you will see an "Erase" option. Allow plenty of time for the process, overnight is a good option.
    When you are ready to try backups again, you will need to completely reset Time Machine by selecting your Time Capsule as the disk you want to use and click Use for Backups. You will need to do this for both computers.
    Try to use an ethernet cable for the first backup by connecting to one of the LAN ports on the Time Capsule and your computer. Allow plenty of time for this. It might take 1-2 days. Once the backup for the first computer is done, then do the other computer the same way. You can probably use wireless for incremental backups since they will be much smaller and faster.
    Post back on your progress.

  • Time capsule not backing up - spotlight doesn't stop indexing!

    I have asked Spotlight not to index the backup drive however it ignores this and continues to try and do so. However it continues to estimate index time without providing a time, and hence the backup never proceeds.
    Rebooting hasn't helped, and I'm even pluggintg the MBP into the TC via ethernet.
    Any ideas please?

    I'm having the same problem. Added the time capsule to the privacy list but this doesn't appear to prevent indexing. Basically every time time machine backup kicks off it indexes the time capsule, which is of no value to me. I believe this is a recent issue, but I can't say for certain what changed. Recent software update? Anyway, did you ever get to the bottom of it? My backups do complete, however it slows down the process and of course i can't use spotlight while its "estimating/completing" index of time capsule.

  • Time Capsule not backing up - but not getting any messages of failure

    Hello, I have had my Time Capsule installed successfully for about 5 months. Two weeks ago, it apparently stopped backing up. I was regularly seeing the hard drive icon appear on my desktop and the spinning icon in the top right hand menu bar, so I was assuming all was well. But recently something else cause me to open time machine to look for a file to restore and I found that Time Capsule hadn't backed anything up recently!
    I received no messages, got no failure notices - nothing!
    Now, when the icon appears, I have checked on the status and right now it says "Indexing backup." I don't know what stage it stops, because the icon just quietly disappears.
    What should I do?

    A clue may be lurking in your logs. See #A1 in [Time Machine - troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum), for a handy widget that will display the backup messages from your logs.
    If that shows errors, see #C2 there.
    If it doesn't, but shows very small amounts of data copied, see #D5 there.

  • Browsers stalling, Time Capsule not backing up

    Hey everyone,
    I've been reading in all the relevant forums—reposting this from Time Capsule forum because I'm not sure which is more appropriate—and I can't quite find something that matches the problem I'm having, so here goes. If I'm rehashing something that's been covered, a link would be much appreciated.
    Browsers on my MBP are completely choking on any and all websites, and Time Machine is unable to run. Our other computers (which don't use the Time Capsule for backup) have no problem with websites. And my MBP seems to be running Mail, Tweetdeck, and printing ok. But for some reason my browsers are chronically stalling (or taking minutes and minutes to load sites like CNN).
    At first I attributed it to a faulty AirPort card in my MBP; I'd taken it in to get the screen replaced, and they replaced the AirPort card for some reason. I've since had that one replaced, but the problem persists.
    It's not just one browser, either. I mostly use Safari, but Firebox seems to have the same problem (or it will load CNN, then choke on the page I nav to afterward). It's also inconsistent; the past few days have been ok, but tonight it wouldn't load anything. Then it inexplicably started working briefly.
    Often, when I quit out of Safari after a page has stalled, I get the beach ball in the Finder for about 10 minutes afterward. The beach ball goes away after that.
    I'm getting a signal just fine, so it's not that. I've noticed my Time Capsule keeps making a start-up sound—like the disk is waking up—when I launch a browser, but nothing happens. The dot on the front is green, so there are no problems. I've run the AirPort Admin many times, and it's not showing anything.
    I've checked for malware too and cleared anything that looked suspicious. I just ran Time Machine Buddy, and it said: "No space left on device. Stopping backupd to allow ejection of backup destination disk." But my Time Machine prefs say I have 970 gigs available.
    Ugh, really frustrated with this. Any help would be really appreciated.

  • Time capsule not backing up since upgrading to Yosemite

    Anyone else having this problem? 

    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. Click Utilities, then Console in the icon grid.
    The title of the Console window should be All Messages. If it isn't, select
              SYSTEM LOG QUERIES ▹ All Messages
    from the log list on the left. If you don't see that list, select
              View ▹ Show Log List
    from the menu bar at the top of the screen.
    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.
    ☞ If all you see are messages that contain the word "Starting," you didn't clear the text field.
    ☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. Don't post more than is requested.
    Please don't indiscriminately dump thousands of lines from the log into this discussion.
    Please don't post screenshots of log messages—post the text.
    ☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
