Sparsebundle Issue

Hi - I have recently purchased a TC .... installed it with no issues and it seemed to be running fine. However it now appears to have an issue with the "sparsebundle" - When trying to use time machine I am getting two errors ... Time Machine error "the backup disk image could not be mounted" and a warning error "the following disk images failed to mount" which I assume is a more detailed version of the previous error "xxx.sparsebundle - reason "Operation not supported on socket"!
Any ideas on how to resolve? Nice one ...G

Welcome to the discussions!
The connection between your Time Capsule and your computer appears to have been lost. Try these steps:
Open System Preferences and open Sharing. Make sure that your computer name appears. Try to eliminate any apostrophes or other punctuation marks and limit to 27 characters or less including spaces.
Open AirPort Utility and click on Manual Setup. Click the Time Capsule tab below the icons. Make sure that your Time Capsule name appears. Use the same guidelines as above.
Also while in AirPort Utility, click the Disks icon, then click the File Sharing tab just below. Make sure there is a check mark next to "Enable File Sharing"
Click in an open area of your desktop to show the Finder menus at the top of the screen. Click on Finder and then click on Preferences and then the General tab. Under the heading of "show these items on the desktop", make sure there is a check mark next to "Connected Servers"
Power down the Time Capsule and wait a few moments, then power it back up.
Now click System Preferences and Time Machine. Choose change disk and click your Time Capsule to highlight it and then click Use For Backups.
Any help?

My Time Machine can't see/connect to my NAS Thecus

Hello,
I have NAS Thecus N7700Pro V2.
I got it to be my network storage and I enabled teh AFP in my NAS to be able to use my Time Machine backup.
My current OS is Lion 10.7.5.
When I open teh Time Machine and try to connect it to my NAS it can't see it.
Please advise.
Thanks!

Thanks - that worked - although the solution requires a little updating which was mentioned further down that post. In summary it is now this:
1. Create a sparsebundle image manually on your local system. Open a terminal window and enter:
hdiutil create -size $SIZESPEC -fs HFS+J -type SPARSEBUNDLE -volname "Backup of $MACHINENAME" $MACHINENAME_$MACADDRESS.sparsebundle
Where $SIZESPEC is the size of the backup volume (followed by the lowercase letter g if Gigabytes, e.g. 100g), and $MACHINENAME_$MAC_ADRESS is your Mac's name followed by an underscore and then your Mac's MAC Address (otherwise known as its Ethernet ID; visible in the Network System Preferences panel), but without the colons. So if your Mac is named MyMac, and the Network System Preferences panel lists your Ethernet ID as 00:18:b3:11:84:dd, then you would use MyMac_0018b31184dd for the name of the sparsebundle.
The -size parameter can probably be as large as you want, now that Apple has evidently fixed the sparsebundle issues that were causing all but the most recent backup to be dumped. However, you can also specify a smaller size if you (like me) want to create a hard limit for the amount of space your Time Machine backups will take on your network drive. hdiutil does have a -resize option if you need to utilize that later.
2. Create and set permissions on your network share. Just make sure you have read/write permissions set on whichever SMB/AFP share you're going to dump this to.
3. Copy the sparsebundle to the network share root. Easy enough. Mount your network share and copy it over. I used this Terminal command after the MyBackup share was mounted: cp -r mymachine_0017f2c8426b.sparsebundle /Volumes/MyBackup/. Or just use the regular UI to copy and paste (it worked for me).

Are there any firmaware updates for time capsule?

Are there any firmware updates for Time Capsule/Time machine?
I just had a new hybrid (SSD and spinning disk) drive (750 GB) installed on my MacBook Pro and used Boot Kamp to partition it and run Windows xp. Now, my previously working Time Machine won't function. It says the "sparsebundle" is open (or in use) preventing the back-up from working properly. When I try and remove and re-install Time Capsule as the disk to back-up to, it still doesn't work. My plan "B" is get a second Time Capsule and dedicate it to the MacBook. But, I fear I'll face the same problem.
When I open to reconfigure Time Machine, the Time Capsule disk is identified as the back-up, but it's also seen in the "available disks to use for back-up" along with with Boot Kamp disk which is part of the new SSD hybrid hard drive just installed. (Remember it's the partitioned part running Windows xp.)
I've unplugged/plugged-in the ethernet internet connection and the power cord many times to no avail. The message still says the sparsebundle is in the way.
Do you think deleting Boot Kamp disk from the list of available hard drives might solve the problem?

TM can only use AFP and only on disks formatted HFS+ (ie Mac Extended Journaled) so it should not bring up a boot camp partition as a possible destination at all .. but I have not done that seutp.
It says the "sparsebundle" is open (or in use)
That error is well known. It should simply required the TC to be restarted..
That sometimes gets things working where the simple restart won't.
I would recommend using short names, with no spaces and pure alphanumeric.
That is C9
http://pondini.org/TM/Troubleshooting.html
If you have a more complicated setup.. I would recommend firstly doing a TM reset in the computer.
See A4 in the same reference.
Do a verify then of the sparsebundle on the TC.. A5 but you might need to inherit the old backup if you want to continue an old backup.. A new hard disk will make the TM consider the old backup no longer belongs to the computer.. there is a UUID connection to the actual hard disk used in the backup.
Again read the info in pondini. B5 and B6.
The sparsebundle in use is C12 but there are a number of sparsebundle issues in section C.. C17 is another common issue.
Some of what you have done is not adequate.. eg disconnecting ethernet is not enough.. you need to reboot the TC.

Time Machine Can't Back Up to Samba NAS

Hi,
I have a Samba NAS on my local network which I can mount manually, copy files to/from etc. quite OK. However, I can't get TM to use it! Here's the log:

Sparsebundle / Migration issues

Mac Mini 2007
10.6.8
OCZ SSD
All was working happily. Back ups being transmitted to 'Time Machined' share on Lacie Ethernet Gb drive. Other Macs do the same and they work find for TM restore and past file review etc.
Yesterday, MacMini bombed. SSD (never use OCZ Petrols) died. On the hung screen panel showed progressing back up ie it was killed in the middle. Last successful back up was Dec 20. Worried that compromised back up will effect integrity of earlier, complete one.
Put in an old but reliable HDD. Installed 10.6. Named computer JAMES afresh in sharing. Pointed TM to Lacie share. Tried to migrate the back up JAMES.sparsebundle (see last para).
Migration assistant listed all the other back up drives from around the office. Failed to show JAMES.sparsebundle anywhere.
Loaded into disk utility. Opened. Ran successful repair. Seemed OK. Also tried terminal clean – failed to function.
Now I cannot access the old backed up files inside JAMES.sparsebundle. Only get todays unbacked up offering. Cannot see back to Dec 20.
Need to restore but am stuck. Can I restore using disk utility to a partition on the newly set up drive? Must I use Migration assistant even though cannot find JAMES.sparsebundle.
Do I need to adjust the plist file in the bundle?
Thank you in advance

See Pondini's TM FAQs, for starters.

Can't copy some files from FileVault Sparsebundle in Time Machine backup

I've got filevault turned on for my mac Mac Mini (10.6.2). I'm using Time Machine to back up to a firewire drive. There's plenty of space - my Mini hd has 250 Gb of 500 used, and I'm backing up to a 750Gb partition on the external drive. The initial backup went OK, and when I logged out it backed up my filevault-protected home directory. When I logged back in, I was able to browse the Backups.backupdb on the external drive, go to the users directory, and open the sparsebundle that was my filevault-protected home directory (after entering the password). I can browse through this backup of my home directory. However, when I try copying files from the backup of the home directory, I get an error:
The Finder can't complete the operation because some data in "(filename)" can't be read or written. (Error code -36).
I get this error for some files, but not all of them. I've tried running BatChmod to reset permissions on all files in my home directory, and then erasing the backup drive and having Time Machine recreate the backup. However I'm still having this problem.
I have also tried restoring the entire hard drive (to a 3rd external HD) by booting from the 10.6 DVD and going through the full-restore process. All of my files are fine when I restore using this method.
Is there something I should do so that I can restore individual files from the backup of my filevault sparsebundle? It is extremly inconvenient to have to do a full hard drive restore if all I want is a file or two, and of course if the motherboard on my mini dies and I can't get a close enough replacement computer, then I could really be up a creek.

Don't try to restore files individually by hand using finder. TM backups are protected by very restrictive ACLs and are not designed to be accessed that way.
you can restore the whole sparse bundle with the home directory from TM interface. you should be logged in as a different user when you do this. the easiest is to be logged in as root so as not to deal with any permissions issues.
another thing you might try is doing it from command line instead of finder. this is also not the designed way but might work where finder copy doesn't.
to do this run the following terminal command after you mount the sparse bundle with backups of the home directory
ditto --noacl path/to/source/file /path/to/target/directory
here path/to/source file is the path to the file in the sparse bundle you want to restore and path/to target directory is the path to the folder where you want to copy it to. an easy way to get the path to an item is to drag that item to the terminal window. make sure that you have all the spaces correctly in the command.

My back up failed and I get a messageTime Machine couldn't complete the backup to "TimeCap". The backup disk image "/Volumes/Data/Mary Fleming's MacBook Pro .sparsebundle" is already in use.

I noticed today that my last back-up was this a.m. and it has tried several times to back up since but I keep getting this message
Time Machine couldn’t complete the backup to “TimeCap”.
The backup disk image “/Volumes/Data/ MacBook Pro ."sparsebundle” is already in use.
I have never had this problem before and don't know what to do. I am not that great around computers so if anyone can help I would appreciate it. I did try to do some research but could not understand any of the content I read. I sure don't know what "sparsebundle" is and this is the first time I ever heard the term.
If anyone can help woold appreciate it.
I have Version 10.9.1

This is a standard issue..
Been around since LION but you missed out.. !! Well the old rule applies.. there are three types of Mac users.
1. The bugs have bitten you, and you have done the work arounds.
2. The bugs are biting you and you are now trying to find out what is going on.
3. The bugs will bite you. And in the meantime you laugh at everyone with problems and say it must be all their fault. Doesn't happen to my system.
You were simply in the last group.. now, with the wonders of mavericks to help, you got bit.
The solution is simple.. unplug the power cord from the TC .. count to 10.. power up the TC again.
No luck look at the more technical help.

Your naming might also be an issue if this continues to happen.. see C9.

Time capsule issues backing up more than one MacBook Pro

Hi all,
i'm having an issue with a new 3Gb Time Capsule i've just bought and put online, I wonder if someone would be able to help please.
I am trying to back up 3 MacBooks, a 2011 macbook pro, a 2012 macbook pro and a 2012 Macbook Air, they are all running Mountain Lion.
My main macbook has worked fine and I have backed up the drive a few times without any real issue, however when I try and back up one of the other two onto the same Time Capsule, I get the error, "the backup disk image "/volumes/data/.sparsebundle" could not be accessed"
I've had a look around all the forums to see if I can see a potential problem and fix, however I can't find anywhere that says it works fine for the first backup but not for any other ones!?
The only other option I have seen is to completely remove the data backup and start again, but I don't really want to do that unless theres no other options.
Hope you can help, thanks in advance.
Oh and one other thing which i've seen, is that you can't backup more than one system unless you re-partition the Time Capsule!? Surely this isn't correct???

You do not have to partition the TC.. indeed you cannot..
But the issue with Lion or ML losing the sparsebundle is now as common as dust in a drought.
Yes, it can do a backup then fail to do another.. and there is no reason for it other than poor networking on later OS.
Reboot the TC.. and maybe the whole network. Reminds you of that initial support question for another OS.. did you turn it off and on again...??

Read C12 and C17.

How can I mount a large sparsebundle (450GB) remotely without it hanging?

I have remote access to my Time Capsule set up and am able to see my files. Files on the drive I have no issue accessing, albeit slowly. Unfortunately, however, the files I need to access are stored in a large backup file.
What I'm hoping is that there is a way to unpackage the sparsebundle locally to the Time Capsule or to extract a subset of files, as attempts to mount the sparsebundle remotely hang and eventually lockup Finder.
Any suggestions?

Sorry but no.. Apple says specifically not to do this. The Time Machine backup should not be accessed remotely and it is unsuitable to use or recover from..
There is no way to extract the files.. The simple fact is Time Machine is on the computer.. it is not on the Time Capsule.. the file on the Time Capsule is merely the backup. There are zero smarts.
If you want to access files you should setup BTMM to the Mac not the TC. Or use remote desktop or a service like TeamViewer.

The troubleshooting C17 is the specific article.

This is generally a Lion error.. and you will need 5.6 utility to get access to the disk area.
So download the real utility. Run it instead of v6 toy version.
http://support.apple.com/kb/DL1482
Go to the manual setup, disk page and click on disconnect all users.. that will unmount all users connected to the disk and allow it to start working. But there are a number of other issues that are possible cause. Pondini lists some of them.

Can I recover FileVault data when the sparsebundle was deleted on a MacBook Pro running OSX 10.6.8?

I have a MacBook Pro that I purchased from a friend of mine. He reformatted it before giving it over to me, and he left me a couple of install files in the Downloads folder before he gave it to me. When I got it, I turned on FileVault because encrypting my data seemed like a good idea. Little did I know that it would end up biting me in the butt.
I tried to add music files from my iPod to the laptop. It didn't work properly, so I deleted those files and tried again. Same issue, and I deleted them again. I noticed, though, that the laptop acted like both copies of those files were still on board, and half my HD was filled up with almost nothing on the computer. I used Disk Inventory to find out why, and found that all that excess data was locked up in a hidden file called a sparsebundle. Disk Inventory removed that file, and then the laptop stopped working. I couldn't get my applications to run properly, and when I restarted the computer, I couldn't log in at all. I rebooted and created a new Admin account so I could get into the laptop.
Now I'm trying to recover all the files that I had put onto the laptop before I had to reboot. They appear to still be there, and I have a copy of the computer in its current state backed up through Time Machine. The programs that were on it before the reboot mostly still worked (exception Firefox, so I'll just reinstall that and hope it works).
Is there any way for me to recover the files that are currently still locked up under FileVault? I have copies of DiskWarrior 4.0 and TechTool Pro 4.6.1, but neither seems to work with OSX 10.6.8. Any help in recovering the "lost" files would be appreciated.
Alternately, if the files cannot be directly recovered: if I have to completely reinstall everything, will having the Time Machine backup of the extra programs my friend had installed let me keep those programs after a reinstallation of OS X?
My thanks to the community in advance for any assistance that can be offered.

oh, I thought I had seen it. I will do a re-install of Snow Leopard, hopefully then I can find it.
Thank you very much, I will let you know how it goes.

Time Machine error -1, cannot access sparsebundle (but not a NAS or WD problem)

Hello, this is my first post here, so I'll try to make it a good one!
I've been wrestling with this problem ever since I bought my Core i7 iMac (SSD + 1TB HD) over a year ago. I have not gotten Time Machine to work during that whole time. Well, I got it to work backing up directly to my internal HD, but that was just a test; it's not what I want. So let me describe this in the most clear and consise way I can:
I want the Time Machine disk to be my Synology NAS. I've configured a share on it correctly. I have an older iMac running SnowLeopard backing up to the same share on the NAS with TimeMachine successfully. But, my iMac won't do it. Whether I create the sparsebundle manually, or I let TimeMachine create it, it always gives the same "error -1". I wrote a more detailed account of my symptoms here (my message is the reply), when I thought this was a NAS-specific issue.
New development: This is not a NAS issue. I found that out by trying an experiment:
First, I tried to back up my SSD using Time Machine to my internal 1TB disk - I selected the "1 TB Secondary Disk" as the Time Machine disk. I initiated the backup, and it worked fine, putting the time machine backup in the "Backups.backupsdb" directory structure at the root of the drive. I then turned off Time Machine and "removed" the 1TB as my backup disk.
Then, I created a sparsebundle at the root of the drive using this command:
hdiutil create -size 150g -fs HFS+J -volname "Time Machine" NAME_xxxxxxxxxxxx.sparsebundle
(where the "xxxxxxxxxxxx" is my ethernet MAC address). I then selected the "1 TB Secondary Disk" as the Time Machine disk again. Time Machine found my sparsebundle and started working with it... and got "error -1"! So even on a local drive, when Time Machine tries to use a sparsebundle for backing up, it still doesn't work.
Now, I have the console log entries that were written during the Time Machine backup attempt:
1/1/13 12:53:59.511 PM com.apple.backupd[4460]: Starting manual backup

1/1/13 12:56:19.265 PM com.apple.backupd[4460]: Failed to eject Time Machine disk image: /Volumes/1 TB Secondary Disk/iMac.sparsebundle
So, here I see it tries to resize the sparsebundle to the full volume size, and fails. I don't think I want it to do this resize, because I don't want it to fill up my whole NAS share. I searched and found this post, which specifies how to set the permissions in the sparsebundle such that it won't be resized. I followed those instructions with a new sparsebundle, and see the same problem... tries to resize, and fails.
I do not have Western Digital software installed and never have.
I've tried everything on this page.
It seems like the attempt to resize is corrupting the sparsebundle. Before starting the backup, I can mount the sparsebundle and manually copy files to it. After attempting the backup, I can mount the sparsebundle, but I cannot copy anything to it manually. Note that I can mount the sparsebundle that the MacBook Pro uses for Time Machine, and manually copy files to and from it (in other words, the correct SnowLeopard configuration does allow manual copying).
I have tried repairing the sparsebundle using the Disk Utility, which restores the ability to manually copy files to it, but Time Machine once again renders it unwriteable when it attempts to back up.
Anyone know of anything else I can try? Thank you so much!
Dan

Yeah, sorry about the broken link. I noticed that link wasn't working after I replied, then I edited my earlier reply. Also, yes, copying the files was just meant as a test; I created new clean sparsebundles for other tries.
Anyway, I'm not too worried about the resizing for now; first things first, let's just get Time Machine working with a sparsebundle at all.
I don't know how to make Time Machine create its own sparsebundle on my local drive; if there isn't a manually created sparsebundle at the root, it just puts everything in the "Backups.backupsdb" directory structure without a sparsebundle. However, it of course does create its own sparsebundle when I point it to my NAS share (as I understand it, Time Machine knows the NAS filesystem doesn't support everything it needs, so it creates the sparsebundle to emulate the correct filesystem). As I have always gotten the same "error -1" when using the NAS share as I did when using the local sparsebundle, I was assuming the same problem was happening in both cases... but now I've checked the console log after doing a backup attempt on the NAS share, and I see different stuff:

So... looking through this, it does some mounting, which all works fine, then it does a create sparsebundle, which appears to work fine, but then it tries to "hide extension", but it can't because it can't find the sparsebundle that it supposedly created. Then it tries three times to eject the NAS share ('TM Backups'), and fails, and gives up. At this time I get the "error -1" pop up on my monitor, and check the NAS share (using the disk utility on the NAS managment page), and sure enough there is the sparsebundle "iMac.sparsebundle". So why does it create it, but then not be able to use it?
Skiing tomorrow, must sleep now. :-)
