Time machine backup disk image

I am just starting to use my Time Capsule and I keep getting this message when I try to do my first backup: "backup disk image could not be mounted". How can I fix it?

Run AirPort Utility, go to Disk, and then choose Erase. Then start over and try to backup again. I'd recommend using an ethernet cable for your first backup.

Time Machine - "backup disk image could not be created"

I have been successfully using the Time Machine to backup my Macbook Pro to an HP Network Server for about six months. A month ago the the Time Machine setup became corrupted and no backups were conducted until yesterday when I found a solution to Time Machine setup problem. Once I set the Time Machine up again, a backup was unsuccessfully attempted with an error message: "backup disk image could not be created" being generated. I followed several other posts on this issue and confirmed my computer is correctly named in the file sharing setup. Since I am not using a Time Capsule - that other suggestions in that post possibly may not apply. The file image showing all of the previous Time Machine backups is present and accessible on my desktop. The NAS is functioning properly. Any help is appreciated.

That sounds like it's trying to create a new sparse bundle for a new set of backups, but can't for some reason.
It's possible that your backups are corrupted; see if you can repair them, per #A5 in Time Machine - Troubleshooting.
If that doesn't help, try re-selecting them in Time Machine Preferences. If still no help, try a "full reset" of Time Machine, per #A4 in the same link.
If still no help, you may need to reset the NAS, or use it's instructions again to "reconnect" to the backups. Unfortunately, that's different for each NAS, so you may have to work with the maker on that.

TS1337 Time machine backup disk image can not be accessed

Hi everyone,
I'm hoping someone can help me as I'm constantly getting the following message:
Time Machine could not complete the backup.
The backup disk image "/Volumes/My name Time Capsu/My name's iMac.sparsebundle" could not be accessed (error -1)
Does anyone know what this means as I can't find anything regarding this message in troubleshooting? My time machine has been running perfectly for well over a year until a couple of days ago.
Any help would be appreciated.
Thanks.

I had this same problem. Unplugged the power for a minute and plugged back in after reading this https://discussions.apple.com/thread/4984048
Working for me now.

Time Machine Backups disk image displays the wrong capacity

I have a USB hard drive partitioned and connected as an airdisk on a time capsule. The drive "TIME" is partitioned for 300 GB and serves both my MacBook (MB) and MacBook Pro (MBP).
If I connect to TIME from Finder, it shows 155.68 GB free of 300 GB total.
When MB runs Time Machine, the Time Machine Backups volume mounts and shows 155.68 GB free of 300 GB total.
Here is what is weird - When MBP runs Time Machine, the Time Machine Backups volume mounts and shows 155.68 GB free of 429.5 GB total.
Why does the MBP show a different and inaccurate total?
I tried reconfiguring Time Machine to point to a different backup drive and then back to TIME hoping it would just 'reset' but that did not work.
Something I just thought of - I did move that sparse from a different volume that was larger. I bet the total size is saved in the information in the sparse.
Can anyone confirm this?
Will this cause me any problems in the long run?

That's possible, depending on how you moved the sparse bundle. If it had a smaller maximum size than the volume it's on, Time Machine would automatically resize it to the size of the volume it's on, making it larger (effective with 10.6.3).
I don't know if it will make a larger one smaller, though.
Will this cause me any problems in the long run?
No. Time Machine will figure out how much space there really is anyway. But if you want to change the size, see #A8 in Time Machine - Troubleshooting (or use the link in *User Tips* at the top of this forum).

Why does time machine backup disk images?

I have Time Machine backing up my folders on my Time Capsule but when I look at the Time Capsule drive in the Finder it shows one Sparse Disk Image Bundle. If I lose a folder on my iMac, how can I easily get the folder off of the Time Capsule? Is there a reason Time Machine and Time Capsule is making this Disk Image and not simply dumping folders on there?

Welcome to Apple Support Communities
If you lose a folder, you just have to open Finder, go to the folder where that folder was and open the Time Machine application, so you will be able to navigate through your backups and restore the folder > http://support.apple.com/kb/HT1427

How do I get back iphone app information from a DELETED Time Machine Backup disk

Hi People,
here is what happened:
I have been using an iPhone App (Audio Memos Free - The Voice Recorder) to record song ideas (I am a songwriter). I have been using it for years.
I backed up my iphone to itunes, and backed up my mac on Time Machine. After a month or so I did a fresh OSX install on my mac, copied all of my files back from Time Machine into my mac, and tried to set up Time Machine. I was not able to do so, so I had to format the Time Machine Backup disk and doing a "fresh" mac Time Machine Backup.
After a week or so, my iphone asks me something like "you do not possess the rights for one or more applications". do not know what i did, but after 1 minute my iPhone was wiped out of all my apps and app contents. I had also the icloud app sync, so i did not worry, recovered from icloud notes, contacts, and all other things. so i did another backup to itunes.
Now i discover icloud did not recover or save the "Audio Memos Free" app content. I know the data are hidden into the Time machine Backup HD, but i do not know where to search for the itunes backup in it.
I know it is in library, but library won't show up.
Any help would be much appreciated.
PS there is a chance that, even without a data recovery, my latest itunes backup was containing these songs, but i do not know how to fish that out of the Time machine drive.
Thank you in advance.

I would email iTunes Customer Service:

Restored system from Time Machine backup disk but the system could not start-up

On MacBook Pro early 2008, restored the entire system from Time Machine backup disk to the entire disk.
The previous system on the backup disk had FileVault turned on.
The restore completed successfully and I was prompted to restart the system via the new restored system disk.
I heard the normal start-up sound, then the Apple logo, but it stuck at the logo screen. And the cooling fan run at almost full speed?
I have been waiting for a few hours, guessing it might FileVault the disk.
Finally I have to shutdown the machine as it stuck at the logo screen forever.
Anyone has the same issue? Any ideas?

BTW, I also tried Repair the system disk, Fix permissions via Disk Utility.
I guess I must lose some files either during the backup or the restore.

Time Machine Backup Disk Cannot be found

While my iMac was in sleep mode, I disconnected the power to my external, firewire time machine backup disk. The backup is a Western Digital hard drive.
Now I get the error message "Your Time Machine Backup Disk Cannot be Found"
I have rebooted the computer with the disk connected and the disk still doesn't show up on the desktop.
I rebooted the computer with the disk powered up but the firewire disconnected, then connected the firewire. The disk still doesn't appear on the desktop.
I tried Disk Warrior, and Disk Warrior doesn't see the external Time Machine disk.
What to do?

That might corrupt your backups, but shouldn't make the disk completely un-usable.
Disconnect it and power it off for several minutes, turn Time Machine OFF, then Restart your Mac again. Let your Mac get powered-up and running before connecting and powering the disk on. Then see if Disk Utility can see it.
Is this a dual-mode disk? If so, try connecting via USB -- it may work that way.
Can you tell if it's running? Is it one with a light, and/or can you hear it run or feel it vibrating?

Error Dialogue: "Time Machine Backup Disk Can't be Found"

Hello -
I am trying to "Enter Time Machine" (which is on a Time Capsule); but when I try this, I am met by the error message "Your Time Machine Backup Disk Can't be Found" with the option given to "Set up My Time Machine".
Needless to say, my Time Machine has been set up for months. When I look in the preferences, it clearly shows the disk I'm connected to (here's a screenshot of the error dialogue alongside my Time Machine preferences: http://cl.ly/1HGk).
Any idea what the best course of action is here.
ADDITIONAL NOTE: notice from the screenshot that Time Machine thinks the earliest backup is only 1 day prior. This is also strange as I have said I've had Time Machine working on this Time Capsule for months. I called Apple about this and was told that a software update had gone out yesterday that reformatted the drives and started the backups all over again. While completely fishy - I don't remember agreeing to any software update dialogue about erasing my Time Capsule - I took them at their word. Not sure if this is related, but thought I should mention it.
Thanks Crew!

The +sparse bundle+ containing your backups may be corrupted. Repair it, per #A5 in Time Machine - Troubleshooting (or use the link in *User Tips* at the top of the +Time Machine+ forum).
If that doesn't help, try a "full reset" of Time Machine, per #A4 there.

That's the first I've heard of that. They may have been referring to the +Time Capsule Backup Update 1.0+ update several weeks ago, that some folks got but others didn't. If it finds a problem, it sends the message in this article: http://support.apple.com/kb/HT4076 The existing sparse bundle is renamed and locked, and a new one made.

Migration Assistant won't see my Time machine backup disk

Hi,
I've seen some other discussions but they apply to slightly different situations and turn out to be too complex for me to follow. My situation is this. My Dec 2008 Macbook running Lion just died. Not sure what the problem is but it seems to be the hardrive. It will take me a while to get it fixed and in the meantime I have a farly new mac mini running Lion.
I also have been making Time Machine backups to an external drive. I read that I could migrate content from a time machine backup and I connected the backup to my mac mini and launched Migration Assistan (MA), seleted the option to migrate from a Time Machine backup. MA is stuck trying to find my disk even though it shows up in Finder. This is the screen I'm talking about http://screencast.com/t/AC0OiVzxx
I'm hoping there is the equivalent of a little on/off switch that I'm not seeing and you can direct me too.
How can I get MA to see my Time Machine backup disk? Thanks for your help.

sorry, i don't know what else it could be then. if you have another external drive you can try doing a full system restore from the TM backups onto that drive and see if MA will recognize that drive and migrate from it. other than this there is always manual migration. slow and tedious but it can be done. see this link for help with that

Verify Disk failed for Time Machine backup disk

Thread <http://discussions.apple.com/thread.jspa?messageID=7930301&#7930301> discussed a similar issue, but it was closed without an answer so I'm opening a new one.
After a power failure I ran Disk Utility to Repair Permissions on my boot disk and Verify Disk on another that I use to store media files; neither had significant problems. Then I ran Verify Disk (verify, not repair; and disk, not permissions) on my Time Machine backup disk. It started spitting out the errors shown below. The time remaining counted up to 16 minutes, but wasn't coming down very fast so I left it running overnight. My machine is set to not sleep or spin down the disks. The next evening it was down to 12 minutes left, and was still spitting out the same errors. The second evening it was done, having failed out as shown in this log file excerpt:

What's going on? Are those errors anything to worry about? Is it possible to run Verify Disk on a Time Machine backup disk? What about Repair Disk?

Any time Disk Utility says you need to repair a disk, you need to repair it. Period.
So run it. If it fails to repair everything, run it again (and again) until it either repairs everything or can't repair any more. If it can't repair it, post back and we'll discuss options.
There's no point in running +Verify Disk+ on an external drive; just run +Repair Disk.+ The only time +Verify Disk+ is needed is for your internal HD (because you can't repair the disk you're running from).
And you need to do that again because of the forced power-down. Any time there's an abnormal shutdown, it's possible the file system on your internal HD can be damaged. Usually it isn't, but it's possible. If that says you need to repair it, you'll have to boot from your Leopard Install disc and use it's copy of DU. Post back if you need to do this but don't know how.

I need to backup my mails from a time machine backup disk from a powerbook leopard to an IMac snow Leopard...can I do this?

Hi everybody...
I need to backup my complete history of emails. I have a time machine backup disk I used in a powerbook intel, second generation with Leopard OS. Now I have an Imac of 24 inches, with Snow Leopard OS. Can I use that backup disk (TM) to put the mails that used to be in the powerbook into my IMac?
My original powerbook is broken, so I cant do anything there...

You should be able to find and restore emails that were on the old Mac via Time Machine. Emails that were on the server, not the Mac, won't be there, of course.
See the blue box in #15 of Time Machine - Frequently Asked Questions.

Can't connect to a Time Machine backup disk

I have erased my TM via Airport Utility
AirPort Utility 6.x: Erase an AirPort Time Capsule disk
So far so good...But now, I am unable to open TM, when I do it opens momentarily, then closes with message "Can't conect to a Time Machine backup disk".
I have turned off TM as I do not want to use the TM as backup..I want to use it as an EHD and transfer data to the disk manually (not by automatic TM backups).
How can I do this?

No. It is not in Finder at all..only I can see the Airport Capusle (on the left side) under "Shared"...but this does not allow for any data transfer.
It should show under "Devices", and allow for data transfer....don't know how to fix this one..

How do I manually erase my Time Machine backup disk?

I have a 500GB external hard drive with only 43 GB left after years of serving as a Time Machine backup disk for another computer. I wanted to use the same disk for my new computer. The new computer's backup is 130 GB, and when I connected the old external drive, Time Machine said "The backup disk needs to be 130.37 GB for the backup but only 47.24 GB are available. Select a larger backup disk or make the backup smaller by excluding files." So I manually deleted the files I found on the external drive onto my computer's trash.
Big mistake. Apparently, there are still only 47.24 GB on the external, but there are no apparent backups or files on it. Furthermore, I can't restore the deleted files to the external hard drive because there isn't enough space on it. Too late, I did some searching and discovered that you can't delete files from a Time Machine external drive manually; you can only go through the gear icon in Finder and remove backups in that way.
So why does my external drive say that it has only 47 GB out of 500 even when there is nothing on it? Is there any other way to manually erase/reformat it?

Try opening Disk Utility and select the highest level drive name on the external drive. Click on the Partitions tab. Remove all the partitions on the drive by selecting each and clicking the "-" sign in the lower left corner of the partition table view. Then choose 1 Partition from the dropdown of partitions to create. Make sure the format shows Mac OS Extended-Journaled. Click Apply.
The above should delete everything on the drive and create a new single formated partition.
