Time Machine backup fails because "volume could not be found".

I just had my logic board replaced in my Macbook Pro and went to do a backup (yeah, I didn't do this right before it crashed) and now Time Machine backup fails with the message "volume could not be found" Under Time Machine/Choose Disk, it appears that the drive is the one selected. The computer "sees" the drive and I can read files on it. The only other thing that has happened in the meantime is that a friend helped pull a file off the hard drive that I needed for a project. No apparent issues there. Any suggestions?

You might try going to /Library/Preferences, then drag the file com.apple.TimeMachine.plist to the Desktop. Reboot your Mac, then try declaring the backup disk for Time Machine. It might help if you mount the backup disk first.
Are you using Time Machine to write its backups to the disk of a Time Capsule? If not, since this discussion section is for Apple's Time Capsule AirPort base station, a discussion involving Time Machine should be held on the discussion section for whatever version of OSX that you're using.

10.5.8 Time Machine Backup Failed Due to Cookie Not Matching?

Been using Time Machine with no problems with 10.5.6 and 10.5.8, but have first problems since 10.5.8. After my iMac wakes from sleep, sometimes I get the error message that the external USB drive that I'm using for Time Machine was removed incorrectly, which is not correct. If I do not get this message and everything looks okay, the next Time Machine backup normally fails and if I check the logging in the widget it tells me that backup failed because the cookie didn't match and it may not be the correct drive. If I restart my iMac, Time Machine works again without problem until the next sleep. Before installing 10.5.8 Time Machine was perfect! Any ideas anyone?

Hi again:
Not really. A restart can be therapeutic at times as a lot of things are reset. I have worked with computers for over 50 years and there are still some things that happen that defy logical explanation!
Trashing a preference file sometimes helps things. A corrupt preference file (rare, but it happens) can cause all sorts of odd behavior.

Time Machine: backups failing because "connection failed"

I have a 500GB external HD connected to my Airport Extreme base station base station via USB, and I use it for wireless Time Machine backups for my iMac and my MBA.
(Yes, I know this setup isn't officially supported. But, it's been working well for a couple years now.)
But over the last few months, backups keep failing because the HD keeps getting disconnected. If I go to find the drive in the finder, it appears, but when I click it, it says "connection failed".
I've found that if I reset the AEX (via airport utility) that allows it to connect, but, never long enough for a full backup to happen.
And, several times recently I've gotten some message about how the backup needs to be verified or something like that- the bottom line is always that the old backups are lost and I need to start all over with the initial backup that takes days. But of course I can never finish it, because it always drops the connection.
At first I thought the problem was only with the iMac backups, which would lead me to believe the drive/router/etc isn't the problem and that it's something on the iMac, but then I had the problem with the MBA too, so I'm guessing it has to be something with the AEX base station (firmware maybe?), or the HD itself...
Is my HD dying? I've run disk utility on it and it checks out OK. Not sure how else to troubleshoot that.
I used to have tons of problems with my internet dropping out when backups were running, but an airport firmware update eventually solved that, and things had been running fine...
I'm running Lion and all the latest software/firmware updates.
Ive found tons of threads about this problem, but they're all at least a year old, and none had a solution...
Does anyone have any thoughts??
Thanks!!

That's not one of Apple's clearest messages -- it means the backups are corrupted beyond OSX's ability to repair them. See #C13 in Time Machine - Troubleshooting.
Is my HD dying?
Possibly.
But more likely is the usual cause -- network or power problems that the Airport can't deal with well enough to prevent corruption.
Part of the reason you're seeing problems now may be more networks, cordless phones, microwaves, etc., in your area causing more network problems. Another part may be that it's only in the last 18 months or so that Time Machine started running the periodic checks to find the problem. You may have had trouble earlier but didn't know it.
Bottom line, you need to find a reliable way to back up.
In your case, it's actually easy: Delete the sparse bundle containing the iMac's backups, and start backing-up to it directly. Then back the MBA up to the same drive (preferably to a separate partition) via your network. See Time Machine - Frequently Asked Question #22 for setup instructions. Also see #33 there.

Recovering Mac HD via Time Machine Backup fails because "Restore system from backup" doesn't show in Utilities Menu of original install. DVD

Hi, after serious problems (troubleshooting didn't help) with my iMac G5 (PPC) running Mac OS X Leopard I've tried to recover my Mac HD via Time Machine (exactly as described by David Pogue on page 242 of the Leopard Missing Manual). However, "Restore system from backup" in the Utilities Menu of my original Leopard installation DVD failed to show up. What can I do?
Any assistance will be greatly appreciated -

Time Machine: Backup Volume Could not be Found

I recently upgraded to Leopard. I have a brand new Lacie external hard drive.
I have tried to use Time Machine with the Lacie HD, but it fails and gives me this message, "Backup volume could not be found."
I did some troubleshooting. I tried to reformat the HD, but that gave me errors as well, stating "Could not unmount disk"
The HD is currently formatted to Mac OS Extended.
I am not certain if this is a problem with the HD, or just user error! I also had problems with iTunes when I tried to move the Library to the HD. I got and error message stating "you don't have sufficient privileges"
I only have 2.5G left on my internal HD, so I am a bit concerned. Any guidance would be much appreciated!!

when you select the TM hard drive in disk utility (the model, not the name) look at the bottom of the DU window. Do you see the line
Partition Map Scheme : GUID Partition Table?
Also, I looked at your first post again and it says that you only have 2.5GB of space available on your main drive. I don't know how big your hard drive is but that's a tiny amount. You need to offload part of your data to a different drive ASAP. when free space gets that low, disk fragmentation becomes a very serious issue. system slows done and start behaving in unpredictable fashion. This can lead to all sorts of problems including directory damage. Run "verify disk" on your main drive and see if any errors are reported. I don't know for sure if this is related to your TM problems but it very well might be.

Time machine has stopped working - 'the backup volume could not be found'

i'm not sure what happened, but my macbook pro hasn't been able to backup to my time machine for the past few weeks. i get a 'delayed' message, then in time machine prefs it says 'the backup volume could not be found.' i can manually mount the backup image, but it still won't backup. my wife's 12" powerbook is backing up perfectly. we both have 10.5.4. i was having the problem before the 7.3.2 firmware update, so that doesn't seem to be the cause. has this happened to anyone else? could my computer somehow lost track if the backup? is there prefs that can be trashed? i don't mind losing my old backups if i need to start over, but i can't figure out how to force it to backup because i keep getting the 'backup volume can't be found' no matter what i do.
my setup: dsl modem into time machine / my macbook pro, my wife's powermac 12", and our apple tv are the only clients.

There is a Time Machine preferences file at

Time Machine: The backup volume could not be found?

I keep getting the message "The backup volume could not be found" when I try to back up my Macbook Pro using an external Lacie USB harddrive. I have tried reformatting the harddrive, and restartet the computer. The external harddrive works normal in Finder, I am able to write and read it, but Time Machine still get this error message. Can anyone help me here?
When I look in the console log, it sais: Volume at path /Volumes/MBP Backup does not appear to be the correct backup volume for this computer. (Cookies do not match)
Where can I delete this cookies?

Airport Extreme/Time Capsule backup volume could not be found?

I am having problem with Time Machine. When I try to backup using Time Machine, I get an error message, " The backup volume could not be found." Strangely, Time Machine recognized the drive when setting the Time Machine preferences, but not when I backup.
If i select from the 'select disk' again and try again i get Keychain Access error 25299 and have to delete that in the Keychain for it to even get to the point of counting down to start back up
I have erased my Time Capsule recently and was starting fresh but now i cannot get time machine running again...
In the shared section of the finder the time machine backup is only appearing in the network area rather than directly there...
Any ideas?
Many thanks.

Hi there.
I would suggest First Aid of your Keychain, but that hardly ever works (especially in this situation).
What I would do first, is go to ~/Library/Keychains/, grab the login.keychain and move it to the desktop. Log out, and log back in again. If that fixes it, then get the old login.keychain from the desktop and put it in the trash. (You will lose all your saved passwords for networks etc.)
If that doesn't work, unfortunately the only option would be to do an Archive & Install.
So you just need to put your 10.6 disk in again and install over the system.
Your personal data/files should still remain intact. Although I would still suggest making a backup (ironic considering the situation)
Cheers

HT3275 Since updating OS to Mountain Lion from leopard, I get the following error message when trying to backup with time machine on external drive. Could not complete backup to media share. The network backup disk does not support the required AFP feat

Since updating OS to Mountain Lion from leopard, I get the following error message when trying to backup with time machine on external drive. "Could not complete backup to media share. The network backup disk does not support the required AFP features." What are AFP features and how do I get Time Machine to backup to my current external backup?

This means that your NAS does not support the required encryption. Update your NAS to the latest firmware or ditch it and buy a Time Capsule (they are the most reliable when using TM).

My time machine has been relatively smooth sailing...until today. After accidentally cutting power to backup drive, I power it back up, shows on desktop, shows in Time Machine...but every backup attempt fails with "The backup volume could not be found. error: 18".

The backup volume could not be found

Spent a fair amount of time on the phone with Apple last night trying to get my Macbook Air to work with Time Machine/Time Capsule.
Symptoms of my problem included Time Machine Preferences giving the error "The backup volume could not be found"
Console messages complaining about not being able to find the MAC address for machine:
(console is accessed by clicking Go -> Utilities -> Console from the Finder, and then selecting All Messages)
11/7/08 11:06:13 AM System Preferences[123] *Time Machine failed to get MAC address for machine.*
11/7/08 11:13:09 AM /System/Library/CoreServices/backupd[1603] Starting standard backup

11/7/08 11:13:14 AM /System/Library/CoreServices/backupd[1603] *Backup failed with error: 18*
And my only network interface was showing up as en1 (instead of en0). You can check this by using Network Utilities:
- On the Finder main menu bar click Go -> Utilities -> Network Utilities
If "Network Interface (en0)" is not an option in the drop down list under "Please select a network interface for information" (mine was showing as en1), then the following steps will probably solve your problem:
1) Enable the root user
- Open the finder
- On the Finder main menu bar click Go -> Utilities -> Directory Utility
- On the menu bar click Edit -> Enable Root User
- set a password (they suggested using the same password as is used for the main user account)
2) Login as the newly enabled root user
- Click Log Out... from the Apple menu on the main menu bar
- select "Other" at the login screen
- enter the user name "root" and the password you set in step 1
3) Drag Preferences folder to the desktop
- open the finder, and click on Macintosh HD and then Library
- drag the Preferences folder onto the desktop
4) Restart the computer
- Click Restart from the Apple menu on the main menu bar
After this, the Network utility should show "Network Interface (en0)", and Time Machine should work.

Jackson,
See this article for the reasons why you see "Time Capsule-1 does not appear to be the right volume..."
[http://discussions.apple.com/thread.jspa?messageID=8116036&#8116036]
As for the error message you are getting, here are several reasons why you would see this message...
*_"Backup Volume Could Not Be Found"_*
First, it is important to distinguish this error message from another, similar Time Machine error that states, “The backup volume could not be mounted”. This is important as the causes and cures for these two errors can be very different.
*Reselect Your Time Machine Disk*
(http://support.apple.com/kb/TS1329)
In the Finder, go up to the "Go" menu and select "Connect to Server".
Click the "Browse" button at the dialogue box.
In the Network window that opens, do you see your TM drive?
Double click it to mount the drive.
Now let's try to reselect it for Time Machine use.
Go to System Preferences --> Time Machine.
Click the "Change Disk..." button.
Select "None" and click "Stop Backing Up".
Now click "Choose Backup Disk" and reselect your drive again.
Close System Preferences and try backing-up again.
On the other hand, does your Time Machine drive NOT appear at all? Is it appearing on your desktop? If it is still connected try disconnecting the cable, waiting a few seconds and then reconnecting the cable. Does the drive mount on the desktop? Try initiating a backup now.
*Disk Fails to Wake From Sleep*
“If your external HD has a sleep function that does not wake for Time Machine backups. Time Machine will alert you that "The backup volume could not be found", and backups will not be made.” [http://support.apple.com/kb/TS1337]
*3rd-Party Disk Utilities* #
Many external hard disks come with software for maintaining/monitoring hard disk activities. It may have come on a separate CD or been installed on the drive itself. If these programs have been installed they may interfere with Time Machine backups, generate erratic behavior, or cause the drive to ‘disappear’ altogether.
You may never know these applications are there as they may be running in the background. Go to System preferences --> Accounts. Select your account in the pane on the left. Click “Login Items”. Are there any items listed there that might refer to hard disk utilities. If so remove them using the “-” button at the bottom.
*Delete Time Machine Preference .plist*
It may be that the preference list that stores the name of your designated backup disk has become corrupted.
Go to --> Macintosh HD / Library / Preferences (Note: NOT Home / Library / Preferences).
Drag the .plist file labeled,
com.apple.TimeMachine.plist
to the root level of your Macs’ hard drive.
Reboot your computer.
This .plist file is automatically recreated at startup if it is missing.
Now try choosing the external HD in the TM Prefs for backup.
*Time Capsule Has a Long Name*
“When using your Time Capsule for Time Machine backups in Mac OS X 10.5 Leopard or later, the Time Capsule backup volume may not mount and Time Machine may not be able to back up to it. This alert may appear: "Backup volume cannot be found". This can happen if the Time Capsule disk has a long name. [http://support.apple.com/kb/HT1170]
Open AirPort Utility (in /Applications/Utilities).
Click your Time Capsule's icon.
Click "Manual Setup".
Enter the password for the Time Capsule if prompted.
Click the Disks icon.
Highlight the volume name that appears under "Time Capsule Disk".
In the Name field, enter a name for the volume that is less than 27 characters long.
Click Update.
After Time Capsule restarts, on the Mac(s)using Time Machine, open Time Machine preferences and reselect the Time Capsule volume.”
Let us know if any of these suggestions help.

Time machine backup fails; error creating folder. Western Digital drive requires password which is perhaps/likely the issue. I can't eliminate the password/encryption.

Time Machine backup fails on new WD external drive (My Passport Studio); error creating folder (after several hours of Time Machine apparently working).
Background: I purchased a Western Digital drive from an Apple Store to use for Time Machine backup. I followed the Western Digital instructions that came with the drive for Mac. I didn't get the Time Machine prompt which the instructions indicated I would receive--namely to select whether I want to encrypt my Time Macine backups. (I already have a Time Machine backup I use at another location, which is perhaps why I didn't receive a prompt.)
I decided to install the Western Digital utilities and security software that comes on the disk--with a view to potentially encrypting the disk (since I still wanted to have an encrypted backup since I was mobile). I forgot that (from experience 2-years previous) that I shouldn't install Western Digital software because it just makes life really complicated.
I tried several times to do a Time Machine backup with failures each time (error creating the backup folder). I tried to get help from WD but I don't think the technicians were following what my issue was. Potentially I was not helpful in explaining it. I deleted the WD applications from my system after the first contact with WD. However the problem persisted--I still had an encrypted hard drive. After three phone sessions with three different WD techs I still could not get a solution. (By the second call I was not at all interested in having an encrypted drive--I just wanted to format and restore the drive to an unencrypted state so that I could have SOME kind of Time Machine backup.)
I still don't have a solution--either to get Time Machine working with the WD encryption/password on the drive, or to remove the encryption so I can backup. Right now my options are to return the drive to the Apple Store -- or get a return authorization from WD. Seems crazy since the drive is fine and I have the working password.

Never install "helpful software" provided by WD and Seagate (or any HD mfg.)
All such stuff is fluff and nonsense that interferes with normal HD operation.
Always when you buy a new HD, format it for Mac and then use it to TM backup or clone a HD, or archive data.
Less is more on HD new out of box. A "blank brick", no fluff and cotton candy software

Backup volume could not be found

Time Machine is unable to back up my system because it continues to experience the following error: Delayed. The Backup volume could not be found. Each time I plug in the TM drive, the icon spins like a backup is starting then the error takes place. So it knows the drive is present but then it rejects it.
Could this have anything to do with the recent repair service I received? From what I can tell, the machine was pretty much gutted: Logic board/mother board/video card, etc.
Thoughts to get me running again?
Thanks in advance,
Shawn

yes. after a logic board change you either need to start a new backup series (reselect the TM drive in TM system preferences) or re-pair the TM drive with the new logic board. Follow this [macosx hint|http://www.macosxhints.com/article.php?story=20080128003716101&query=repai r%2BTime%2Bmachine].

Everything was OK - now have "The backup volume could not be found" error

Setup:
* MacBook Air
* MacBook 10.5.5
* Mac Mini with external hard drive with 2 partitions, one of which is called "Time Machine", 10.5.5
What was working:
MacBook Air and MacBook would backup with Time Machine over wireless connection to .sparseimage files on the "Time Machine" volume connected to the Mac Mini.
Change:
Had to give the MacBook Air back to my old employer, so I "merged" the MacBook Air onto the MacBook (the merge was somewhat convoluted, and unrelated to my issue I think: I used SuperDuper to copy the MacBook Air hard drive onto a new SATA notebook drive. Then I installed that drive in the MacBook. Then I used Migration Assistant to copy the user from the original MacBook SATA drive onto the new drive in the MacBook. Now I have two users on the MacBook, whereas before I had one use on each of two computers).
Symptom:
Now I cannot use Time Machine to backup the MacBook to the "Time Machine" volume. Everything I've tried causes Time Machine to briefly "prepare" the backup, then return the error "The backup volume could not be found". Things I've tried:
* Mounting the volume "Time Machine" on the MacBook, under either user, works fine - I can write, read, and delete from the volume.
* Deleting the old .sparseimage backup files from the "Time Machine" volume.
* Erasing the "Time Machine" volume with Disk Utility on the Mac Mini.
* Using "Change Disk..." in Time Machine to re-select the volume "Time Machine"
* Using "Change Disk..." in Time Machine to select None, then restarting, then re-selecting the volume "Time Machine"
* Making the volume "Time Machine" read/write by guests, then connecting to it from the MacBook as a guest instead of as an admin user.
* Repairing permissions and/or repairing disks using Disk Utility on all applicable volumes.
* Tried all of the above under both users on the MacBook (both of whom are Admin users)
None of these things have worked, they all exhibit the same symptom when I manually start a time machine, or when I wait for Time Machine to automatically start the backup.
Any ideas of what I can try next?

Consider these reasons for this error...

HT1338 Error preparing Time Machine backup disc- size error usually not being multiples of 512, encryption

Trying to encrypt Time Machine backup disc getting message - Error preparing Time Machine backup disc- size error usually not being multiples of 512, encryption.

I got the same problem.
But I think it cannot be related to not being a multiple of 512.
As when I devide the number of bytes 3.000.592.982.016 by 512 is equals 5860533168.
3.000.592.982.016 / 512 = 5860533168.
So what could be the real problem?
With kind Regards
