HT3275 message: "Your Time Machine backup disk can't be found." Mountain Lion. Western Digital "MY Book" "Home edition"

Intalled Mountain Lion. Now get message: "Time machine backup disk can't be found. Using Western Digital "My Book" "Home Edition"

Wow, I feel really stupid. I spent a couple of days trying to troubleshoot this problem.
1. Open TM prefs.
2. Click "Select Disk..."
3. Select "None" and apply changes.
4. Click "Select Disk..." Select your disk and apply changes.
*5. When the password prompt appears, MAKE SURE THE NAME IS THE NAME OF THE AIRPORT BASESTATION, and not the name of your Mac.
6. Run a backup.

HT201250 "Your Time Machine Backup Disk can't be found" ? Disk is attached and running, apparently smoothly.

I am getting this message that my backup disk cannot be found. However, it was working fine just yesterday and there is no indication that the disk itself has crashed. It appears to be running as usual. Any suggestions about how to get my iMac to "find" my lost Time Mache disk will be appreciated.

Have you tried restarting your computer and disk?

Your Time Machine backup disk can't be found.

I clicked set up/select disk/Set up Time Capsule and got the notification that the Airport Utility was unable to find any Airport Wireless devices.....the wireless devise is plugged in and in range (or I presume so as the internet connection is working and the AirPort is connected.....).......any suggestions on next steps appreciated.
Some contextual info:
I am on Snow Leopard with an Apple Time Capsule
last back up was on 30th July (which was the day we left to go on holiday for 4 wks, when I took the recommended action of shutting down)
Time machne button is clicked to on

maybe your TC hiccupped a bit on repower.
First Aid
Power off of the TC
Power off all other network participants
Repower the TC and give it a minute or two to run up completely till the green light is definitively on.
Rejoin the other network participants one after the other, giving each device a little time to establish all connections.
If that doesnt fix your hustle, report back with any error message and eventually any information about your setup you think it may be useful.

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.

I am getting error "The disk is used for Time Machine Backup" when installing the new OSX Mountain Lion upgrade"

I am keep getting this error "The disk is used for Time Machine Backup" when installing the new OSX Mountain Lion" when doing the upgrade to newly OS.

The folder would be at the root of your hard drive. Double-click Macintosh HD and look there.
If it isn’t there, I’m not sure what it is seeing.

Time Machine backup history present but inaccessible after Mountain Lion clean install

Hi all,
A few days ago, I took the Mountain Lion plunge and after performing all the preliminary data copying to external hard drives as well as on last Time Machine backup to my dedicated Time Machine external hard drive, I booted from my ML recovery USB thumb drive, reformatted the internal HD, and proceeded to perform a clean install of OS X 10.8.
The ML install and initial setup completed without a hitch, and I had no difficulty in reconnecting to my existing Time Machine EHD and performing an initial backup of the freshly upgraded Mountain Lion system. It took several minutes in the "preparing backup" phase; but once it got through that, it backed up my entire system (which was basically nothing more than the new OS and iLife at this point) within an hour or so. Time Machine has since worked reliably in performing the automatic backups every hour.
But here's the problem: My backup history went back all the way to March 2011 before the ML upgrade, and it still (sorta kinda) does now. However, although I can see all of the backup history tick marks when I enter TM, the ONLY SELECTABLE backups are from the point where ML was installed and onward. The previous Lion and Snow Leopard backups are visible; just not selectable. I also verified that the physical backup folders are still present on my TM EHD dating all the way back to last March. I ran a verify and repair operation on the TM volume, and it came back clean. I have disconnected and reconnected the TM EHD to TM and of course rebooted, but no joy. TM did not force me to "start over" with a new backup as some posters have complained of. And it seems to be working fine otherwise.
Has anyone else had a similar experience after upgrading to ML? Any thoughts on how I might reconnect to my TM backup history?
Thanks in advance for your thoughts.

How did you put your data back after the erase?
I didn't, or rather I haven't yet. Basically, all I have done so far is:
Reformat Lion HD and install ML clean from USB thumb drive
Run through initial virgin boot setup, e.g. enter my Apple ID and desired user account info
Change a few preferences (the "use right side of mouse for secondary click" setting first and foremost!)
Configured Time Machine to use pre-existing Time Machine Backups EHD and let it do initial backup (which it simply added on to the existing backup history as I had hoped)
Drag-and-drop copied my saved iTunes library (~50 GB) from my ext. FW drive to my new Home Music folder and confirmed that iTunes was working and able to sync with my iPhone and iPad
Installed the iLife suite from my Bundled Applications DVD and then updated those apps via the App Store
Obviously the iTunes folder is an exception to "I haven't yet", but basically, the Lion's share (pun intended) of my previous data has not yet been copied back from the temporary storage on the EHD.
The reason you can't see the backups of the old home folder from the new one is simply that they have different names.
Yes, I know that now. Everything was fine all along. I just didn't realize that TM [quite sensibly] grays out any backup history finder windows and right-hand-side tick marks that contain no backup of the folder currently in focus. Since the folder I had in focus was one that didn't exist before I installed Mountain Lion, there was nothing to access except for the most recent post-upgrade backups.
Thanks much for your help.

My time machine backup was created on iMac with Mountain Lion and my new iMac has Mavericks installed, will I be able to restore a backup from time machine to new imac and all applications work ok

time machine backup to new iMac

Yes, however it's always wise to update your apps to ensure you have the most up-to-date version. Use Setup Assistant to migrate your data, apps and settings to the new iMac, simply follow the on-screen directions. If the new machine has already arrived and you have already run Setup Assistant, connect the TM backup to the new machine and run Migration Assistant (a cousin of Setup Assistant) and follow the on-screen directions. You can find Migration Assistant in Applications - Utilities - Migrations Assistant or you can use the keyboard shortcut of Command + Spacebar and type "Migration Assistant".

Time machine backup from OSX 10.5 to Mountain lion doesn't want to recover.

Hi!
I have just upgraded my iMac from 2007, from the original oreparting system (10.5?) to mountain lion.
I had read a lot about the problems with loosing files so I made a complete backup of the computer using time machine.
I then updated to snow leopard as a "from scratch" installment and then upgraded to mountain lion via the app store.
I therefore had a completely blank computer with only mountain lion installed.
When I now try to take my time machine backup that I did and install it straight over, then it says:
"The operation can’t be completed because you don’t have permission to access “.localized”." or the same sentence but something else instead of localized.
Any tips on how I can try to sort this out?
Thanks!
Annika

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?

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..

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.

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:

At that point the whole system was extremely sluggish, and the access light on the backup disk was flashing steadily. The pmTool process seemed to be running away, but the system wasn't responsive enough for me to do much about it, so I held down the power button to shutdown. Upon the 2nd restart the system booted and seems to be OK, but I'm leery of running another Verify Disk.
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.

Time Machine "Backup Disk Not Available" over WAN

I have port forwarded port 46 (TCP and UDP) to port 548 a Mac mini server running Mac OS X 10.6.8, and I have Time Machine backup disk on it set as a share point with Time Machine support enabled. On my Mac Pro running OS X 10.8.5, I am able to connect via AFP to my server with the address "afp://my-ip-address:46" and can read and write on the backup disk share point. I tested that, and it works. When I am on the same LAN as the server, I can use that disk for Time Machine and have been doing so for years. However, I cannot do a Time Machine backup to that share point over the WAN. When I open Time Machine preferences, I can select the share point as my backup disk, but once I start the backup, it says "Backup disk not available" and fails to start. How could I fix this problem?
In case you're wondering, I forward port 46 to port 548 instead of port 548 to port 548 to minimize hacking attempts. Last time I used a default port, a computer in Taiwan started spamming SSH authentication failures.

I did find this article via Google
<http://www.macgurulounge.com/make-time-machine-remotely-back-up-to-your-time-cap sule/>
Personally, I use CrashPlan (free option using my own disks) to backup over the internet. It works very well when I'm away from home. Everything is encrypted.
