Time Machine Not Compacting SparseBundle on Time Capsule

Hi
I am running Snow Leopard 10.6.4 and have a time capsule to hold my iTunes Library and act as my Time Machine repository.
I'm experiencing the problem where Time Machine has filled up my 1TB Time Capsule, and will not back up any more.
I can see that Time Machine has tried to delete some old backups in order to create space - in fact it's deleted ALL my old back ups bar one, probably due to the fact that in deleting each old back up has not released any more space on the Time Capsule as the Sparse Bundle is still massive.
I have done some research and can see that other people were having this issue back in 2008 - so I thought it would have been resolved by now! I thought Time Machine was supposed to compact the sparse bundle image once it had deleted an image these days - but it doesn't seem to have happened.
Can someone tell me if there is some setting I need to select?
I might as well delete the current sparsebundle and just start again - so I don't want to find myself in the same situation in X months time!
Many thanks
Darren

I can't get back to some of the earlier logs as the widget crashes and takes down the whole dashboard with it! However I think I remember seeing some messages that stated that it couldn't compact the drive as it was already mounted.
I do use the drive to store my iTunes library as well - so perhaps I had mounted the drive when it ran out of space, and hence it's decision to try and remove all the previous backups.
Perhaps this is a good time to think about creating a disk image on the TC for TM to use so I can keep the backups separate from the other data.
Should I create a disk image and store all the iTunes data in it and let TM use the standard TC or vice versa and create an image for TM to use and then use the native TC for data - or does it not make any difference at all?
Cheers for your help

    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.

  • Time Machine couldn't complete the backup to "Time Capsule. The backup disk image /Volumes/Data/MacBook Pro.sparsebundle could not be created (error 60)"

    We are Mountain Lion using Time Machine to backup to Time Capsule. When the backup tries to run, an error appears after a couple of minutes saying "The disk you inserted was not readable by this computer." Then an error shows up saying "Time Machine couldn't complete the backup to "Time Capsule.The backup disk image /Volumes/Data/MacBook Pro.sparsebundle could not be created (error 60)"
    I low level reformatted the Time Capsule and that didn't fix it. I then tried using Time Machine on another computer to back up to that same Time Capsule and it worked- so I'm doubting it's the Time Capsule.
    I've noticed that when Time Machine runs, that a  folder called Data  at /Volumes/ appears while Time Machine is trying to back up. I think it's making the sparsebundle to transfer to the Time Capsule.
    However, after a couple of minutes- it comes back saying that the disk is unreadable.
    I think it's something wrong with either creating the sparsebundle or opening the disk image that seems to be a part of the Time Machine backup process on the local drive. 
    I am able to create a disk image with Disk Utilitiy without any problem on that system. I've repaired the disk and disk permissions with Disk Utility and replaced the directory with Disk Warrior. I've trashed what preference files I could find and restarted. I've completely removed the backup destination from the computer and added it back again.
    Help!
    Thanks,

    Yes, exactly.  It makes one sparse bundle per Mac.
    It's possible the TC's disk is too full for a new sparse bundle, or there may be some other problem.
    Via the Finder, locate the existing sparse bundle (see the pink box in Time Machine - Frequently Asked Question #17 if you're not sure how to do that).  See how large it is (plus how large anything else that may be there).  If the total is very near the size of the TC, that may be the problem.
    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 (probably the first one displayed), then copy and post all the messages here.

    Please help! Got myself a timecapsule a few months back. I just use it to back up my mac, and also have a wireless printer connected. I have a Macbook Pro (Mac OS X 10.7.3). When I first got my Time Capsule it backed up flawlessly, but in the last few months has started showing the message above. So now it wont back up at all.
    Have done probably 2 system updates during this time, and even a firmware update a few days ago for the timecapsule. This recent firmware update seem to fix it for a day, but now the problem is back!!! Even Mac support wasnt able to help last time I called.

  • Hi - i got a problem with time capsule stating all of a sudden: time machine error (-1) could not access the image (Name) Macintosh.sparsebundle

    Hi - can anybody support me with a time capsule error message (-1) : could not access macintosh.sparesbundle? mny TXS

    This is a Lion bug. compounded probably by the bugs in 7.6 and later firmware of the TC.
    Rebooting the TC is disconnecting the users .. Lion is failing to unmount the TC after a backup. Reboot is forcing it to do so.
    But if you download and install the non-toy version airport utility for lion.. which still has a disk page.
    http://support.apple.com/kb/DL1482
    Install and run that exclusively, on the disk page is a simple icon, disconnect all users.. wonder why they have that icon.. well now you know. So you don't need to reboot the TC. Just press the button (icon) so to speak.

  • Limit Time Machine backup/sparsebundle so one machine doesn't hog all the time capsule space?

    Is this possible?
    I have a brand new time capsule, my wife and I will be backing up our computers to it using Time Machine. Is it possible to limit the storage size of the sparsebundles so one of us (probably me) wont hog all the space?
    My wife doesn't use her's as much, while my computer is on almost everyday, so I'm affraid my computer will limit the amount of states, or versions, that she can back up before her time machine has to start deleting old files.
    I'm trying to avoid a situation where my time machine goes back a year while her's only goes back a few months.
    Thanks!

    No. That is not how a Time Capsule and Time Machine work. All backups are adding to existing backups.
    About TM "Backup Drive is Full"
    Alert TM only deletes older files if they have been deleted from the source and when TM needs space on the backup drive for a new incremental backup. Time Machine "thins" it's backups; hourly backups over 24 hours old, except the first of the day; those "daily" backups over 30 days old, except the first of the week. The weeklies are kept as long as there's room.
    So, how long a backup file remains depends on how long it was on your Mac before being deleted, assuming you do at least one backup per day. If it was there for at least 24 hours, it will be kept for at least a month. If it was there for at least a week, it will be kept as long as there's room.
    Note, that on a Time Capsule the sparsebundle grows in size as needed, but doesn't shrink. Thus, from the user's view of the TC it appears that no space has been freed, although there may be space in the sparsebundle.
    Once TM has found it cannot free up enough space for a new backup it reports the disk is full. You can either erase the backup drive and start your backups anew or replace the drive with a larger drive.
    To accomplish what you want would mean using just an external backup drive partitioned with volumes for each of you to use, and the use of a different backup utility that overwrites old files rather than saving them as does Time Machine.

  • Why won't my MacBook Pro backup to Time Machine (on my 1TB Time Capsule) when I'm running Lion OSX 10.7.5.? What does it mean when this error pops up: MacBook Pro.sparse bundle could not be assessed (error - 1).???? Please help me fix this!

    Apparently I am not the only person having this problem as I have seen many threads about it. If ANYONE OUT THERE CAN HELP ME, I WOULD SINCERELY APPRECIATE IT.
    I try and run my backup as I always have, but it HAS NEVER COMPLETED SINCE I UPGRADED TO LION. As many mentions, I updated from 10.7.4 to 10.7.5 hoping that would fix my issue and it didn't help at all. I also unistalled WD SmartWare to no avail. It's really starting to annoy me since I have as much money invested in my MacBook Pro and Time Capsule as I do in my car....
    I have more than enough space on the Time Capsule, but Time Machine is still failing and coming up with an error message: MacBook Pro.sparsebundle could not be assessed (error - 1).

  • How can I close my Time Machine Sparsebundle so Time Capsule can do a scheduled backup?

    "Time Machine couldn't complete the backup to "Your Time Capsule". The backup disk image “/Volumes/Steven Weinberg's Time Caps-1/Steven Weinberg’s MacBook Pro (4).sparsebundle” is already in use."
    I have both a Time Capsule and a 2Tb external drive using Time Machine to back up my laptop.
    Is it as simple as when the Time Capsule goes to do a backup and finds that the other drive is in the midst of using Time Machine to do its backup that I get this notice on my desktop?
    It's 10:30 AM now.  The last Time Capsule backup was almost 12 hours ago.
    There have already been 6 Time Machine backups today on the 2nd drive.
    Sounds like the Time Capsule really is being blocked from doing its job.
    THe 1 Tb Time Capsule backs up to a .sparsebundle document which fills the Time Capsule at 985 Gb.  You can't open and peek inside the .sparsebundle backup file.
    The other drive backs up to a .backupdb folder within which are subfolders for each backup which appears to be a complete recreation of thebacked-up 500 Gb hard drive on my MacBook Pro laptop.  And even though there are 37 separate folders with backups going back to Sept 2013 when I installed the second backup drive, it's only used about 500 Gb of its 2 Tb capacity.
    1.  How can I solve my primary problem of freeing up the .sparsebundle file for the Time Capsule?
    2.  Since both drives are using Time Machine to do the backup, why are they producing such diffrent backup file structures?

    I now realize that the folder in which the problem file(s) are stored on the backup,.DocumentRevisions-V100, is the folder in which OS X stores its versioning data for all users. I am now trying to work out whether I can safely delete these files from the backup
    That does get damaged on occasion.  I haven't seen it in quite a while, so it's pretty rare.
    You can delete it from the backups, via the TM interface, but you must be able to show invisible items). 
    First, open the Terminal app (in your Applications/Utilities folder). Be very careful with this app.  It's a direct link into UNIX, the underpinnings of OSX, but without the protections of OSX.
    In Terminal, the prompt looks like this:  <Computer Name>:~ <your name>$
    (where <your name> is your short user name).  It's followed by a non-blinking block cursor.
    Copy, do not type, the following after the prompt:
    defaults write com.apple.finder AppleShowAllFiles 1
    and press Return.
    You should just see the prompt again.
    Then see Time Machine - Frequently Asked Question #12 to delete all the backups of it.
    and from the live system filestore so they don't get copied out to a backup again.
    Yes. You will, of course, lose all previous versions, but since the file is corrupted, you may have lost some, most, or all of them already.
    When done, run the same command to hide the invisible items, but replace the "1" with a zero.

  • Disk Utility hangs ("not responding") when attempting to Repair Disk on Time Capsule sparsebundle.  Help.

    I am trying to improve the performance of my Time Machine backup and retrievals via my 2nd Gen. Time Capsule from my iMac Core 2 Duo hard drive with SL 10.6.8.  The incremental backups generally take 20 - 40 minutes each hour generally with fewer than 100 MB of data being backed up.  I have read through numerous threads on these forums about Time Capsule and Time Machine issues as well as the very helpful Pondini site (http://web.me.com/pondini/Time_Machine/Home.html) and have tried many other suggestions (listed below), but have been unable to attempt a Disk Utility repair disk on the Time Capsule sparsebundle file.
    After locating the sparsebundle 'file' in the finder under Shared/TC/Data, I am only sometimes able to drag the sparsebundle into the Disk Utility volumes and disk window.  About fifty percent of the time, Disk Utility hangs when attempting to drag in the sparsebundle.  If I am able to get it listed and click on "repair disk", then the beach ball begins to spin and nothing happens.  This occurs whether or not I first use AirPort Utility to "Disconnect All Users" from the Time Capsule.  I have given it over one hour to attempt the repair disk, but nothing happens, i.e., not a single message shows up in the detail window.  The beach ball just spins, and Disk Utility shows up in red as "not responding" under the Force Quit menu.
    Also note that on my new Macbook Air, Time Machine runs quite quickly via this same Time Capsule from my new Macbook Air using OS X Lion (which seems to indicate that the Time Capsule drive itself is OK).
    I would appreciate any tips on getting Disk Utility to run "repair disk" on my sparsebundle, as I seem to have exhausted most other options (see below) for improving Time Capsule performance -- aside of course, from wiping the Time Capsule clean and starting all over.... (which I really don't want to do, and from what I've read, has not helped some people who've tried this anyway).
    Many thanks!
    Although I would like to focus this thread on the Disk Utility / sparsebundle "Repair Disk" problem, I should mention that I have tried the following other things:
    1.  Repaired disk permissions on my hard drive
    2.  Used Disk Utility to run "repair disk" on my hard drive after starting up from a SuperDuper external backup
    3.  Run DiskWarrior on my hard drive, again, from a separate startup disk
    4.  Did the "full reset of Time Machine", a la Pondini Troubleshooting #A4
    5.  Changed my computer and Time Capsule names to simple short names with only alphanumeric characters and no spaces
    6.  Ensured that my Time Capsule is being accessed only via ethernet
    7.  Relaunched the finder
    8.  And finally, attempting to use Disk Utility to repair the sparsebundle - thus the nature of this post

    OK, no takers out there, but I answered my own question (sort of).
    The answer is that even though Disk Utility shows up as "not responding" under the Force Quit menu and appears to hang, it is actually still working.  A bit of patience shows that after about an hour, my Disk Utility was able to show the 1.44 TB Time Machine sparsebundle from Time Capsule in the disk window on the left hand side.  Once this appeared, I was able to click on "Repair Disk" (note that prior to doing this, I had to "Disconnect All Users" from my Time Capsule using the Airport Utility program; otherwise you will get a "could not unmount disk" error).  Again, the Repair Disk function appeared to hang Disk Utility as it showed up as "not responding" under the Force Quit menu.  However, after about 8 hours, Disk Utility did run the entire Repair Disk protocol on the sparsebundle.  The results DO NOT show up in the Disk Utility details window - so even if you are patient enough to let it complete, you will not see anything and may think that nothing happened.  However, you can find the familiar results of the Repair Disk function by looking on Console - find the "DiskUtility.log" under Files: ˜/Library/Logs.
    Unfortunately, I was hoping to find a problem that would have been subsequently repaired which would result in dramatically increased Time Capsule speed, but this was not the case.  Disk Utility showed everything to be "OK" and I am stuck with a very slow Time Capsule....
    (And of note, my new Macbook Air (OS Lion) Time Machine functions blazingly fast on both backup and retrieval to and from the very same Time Capsule - even though, these are occuring wirelessly via AirPort -- granted the size of this sparsebundle is an order of magnitude smaller at this point, i.e., only 10 GB right now)
    Would still be happy to hear of any similar experiences or tips on getting Time Capsule to work more quickly.

  • 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

  • RE: Where are Time Machine sparsebundle files on Time Capsule?

    I recently bought a Time Capsule. After some odd issues trying to get it to work in place of my Airport Extreme, it looked like it was finally working correctly.
    When I first turned it on (before the problems getting it to work wirelessly), I did a full backup with Time Machine on the Capsule via Ethernet. When I clicked on the Time Capsule, I could see the sparsebundle files with a number and a date.
    Somewhere down the line, I knocked all of our computers offline while trying to get Time Capsule to replace the Airport Extreme station after I ran the first backup on it.
    I finally had to call Apple Support to have them walk me through setting up Time Capsule correctly and get us back online. After several attempts, we finally got it all working, but in the process the original backup files disappeared from Time Capsule, so I ran Time Machine again. It said it completed the full backup (again), and it was doing incremental backups.
    My problem is, I cannot see any files on the Time Capsule when I click on it. Is that the way Time Machine/Time Capsule are supposed to work? No folder called Backup, no files. When I enter Time Machine, I see that it's backing up, but it kind of worries me that I can't SEE the sparsebundle files anywhere.
    Any idea of where those files are hiding? I guess I'm used to using Backup, where I could actually see a list of files.

    Any idea of where those files are hiding? I guess I'm used to using Backup, where I could actually see a list of files.
    Time Machine stores backups over the network in the form of a sparse bundle "file". This file should show up in Finder as "ComputerName_MACaddress.sparsebundle". However, the sparse bundle is not actually a file, but a container/folder with a number of files, called bands within it.
    You can access the backup files within the sparse bundle, by using Finder, as follows:
    o From within Finder, click on the Time Capsule (TC) that appears under the Shared category
    o Double-click on the TC's disk name
    o Double-click on the sparse bundle
    It may take a while but eventually the disk image will open and you will see a folder named "Backups.backupd." This folder contains the Time machine backups.
