Permissions on TM backup disk

Hi,
I have trouble with my external disk which I'm using as TM drive, so I brought it to work. The issue seems to be a stupid power adapter issue and I got my drive working now. Mounting that drive on my work Mac it shows up as a normal external drive and not as a TM drive. Owners are not enabled and I can access any file in the backup. Is that normal or missed I anything during configuration of TM? The TM drive I'm using at work mounts as TM drive and has permissions enabled, so I can't access other user's files. Have to check again at home, but it looks like the permissions on a TM drive are working only on the Mac that is backup'ed. Is that true? Guess I should keep the TM drive at a safe place then...
Thanks,
Thomas

Need to change permissions if moving backup disk to Server?

I have a Time Machine backup disk that's been directly connected to a client machine. There is much free space still left on that drive and we're retiring the client. I'd like to move that backup drive to our OS X Server machine and have it backup a few other clients that connect to it.
I understand there's difficulty in directly moving a backup drive to a server and having TM backups continue, incrementally, as usual.
I'm not so interested in accomplishing that as I am making insuring the integrity of future backups. What concerns me the most is that on the old client the drive's owner was jill and after moving it to our server it's owner is jeff (whom happens to be logged into the server right now). BUT, all our shared drives are owned by localadmin as required during the LDAP/Open Directory setup that I can't fully remember right now.
should I change ownership of this drive? Make it a Share Point in Server Admin? If so what happens to that old Backups.packupd folder and it's contents. Could they still be used to recover files from Jill's old account?
Sorry for the confusion...

Just get the new machine? If so, which option did you use to migrate? Is the old machine a PPC and the new one an ICBM (Intel-chip-based Mac)? If a new machine, you might reconsider how you did things, restore the new machine to factory specs, and start over. See http://discussions.apple.com/thread.jspa?messageID=1872713 for starters.

"Time Machine could not complete the backup. The backup disk is not availab

I have a Seagate 750 MB external disk connected to the USB port of my Airport Extreme Base Station. It worked fine with Time Machine under Leopard but it's not working the way it was under OS X 10.6.2. I'm hopeful someone can help me solve the problem.
Let's say the name of my Airport Extreme Base Station is "Airport." If I remember correctly, under Leopard time machine would start a wireless backup not long after I turned on the Seagate drive. That no longer happens.
I've erased and re-formatted the Seagate drive with 2 GUID partitions, one for my 24" iMac and one for my 17" MacBook Pro. Both computers are about 3 years old. In order to do the re-partitioning, I had to unplug the Seagate drive from the base station and plug it into one of the iMac's USB ports. If I didn't do this, nothing other than the iMac's drive appears in the left pane of Disk Utility, although the name of my base station, i.e, "Airport" does appear in the Finder and PathFinder (a replacement for Finder that I use).
In fact, Time Machine works under 10.6.2. as long as the Seagate drive is plugged into the iMac's USB port. As soon as I plug the Seagate drive into the USB port of the base station, Time Machine no longer works. The backup is "delayed." When I click on "Back Up Now" a few seconds go by and I get the following dialog box: "Time Machine could not complete the backup. The backup disk is not available."
In my Airport Extreme Base Station setup (Airport Utility version 5.4.2), the "Disks" pane sees both partitions on the Seagate drive. File sharing is enabled on the "File sharing" pane and "Secure Shared Disks:" is set to "With a disk password." "Airport Disks Guest Access:" is not allowed, nor is "Share disks over WAN."
When the Seagate drive is plugged into the base station and I click on "Airport" in the Finder or PathFinder, I'm prompted for the password I mentioned above because the shared disks are secured with a password. Once the password is typed, both partitions on the Seagate drive appear in Finder and PathFinder. When I try a Time Machine backup at this point, I get the same error I described above, i.e., "Time Machine could not complete the backup. The backup disk is not available."
One last thing, I did an "Archive and Install" when I upgraded to Snow Leopard since I thought the changes were relatively minor as compared with past OS X upgrades. Normally, I do a clean install but didn't feel like it this time. I also tried deleting the file /Library/Preferences/com.apple.TimeMachine.plist to no avail and restarted my iMac to no avail.
At this point I'm completely stumped. As I said, Time Machine works as long as the Seagate drive is plugged directly into one of the iMac's USB ports as opposed to the base station's USB port. But doesn't this defeat the purpose of having wireless backup? Once again, the wireless backup worked fine under 10.5.8.
I hope my message is clear and a solution would be most welcome.
Thank you,
Richard

I'm having the same problem. If my TimeMachine drive is not connected, I'll get the "Time machine could not complete the backup" "The backup disk is not available" warning a couple times a day. This is extremely problematic if I'm giving a presentation. I have tried changing my TimeMachine drive, removing that drive, repairing permissions, and have not been able to solve the problem.
Please help!

Cannot Connect to Time Capsule: "the backup disk is not available"

I am having a problem that I can't diagnose with my 500 GB Time Capsule (my HD is 128GB). The firmware is current. I first did a search for 'the backup disk is not available' since that is the message displayed in the Time Machine window (with the red checkmark).The Time Machine widget says this:
Attempting to mount network destination using URL: afp://[email protected]/xxx%20xxx's%20Time%20Capsu
NetAuthConnectToServerSync failed with error: 89 for url: afp://[email protected]/xxx%20xxx's%20Time%20Capsu
I installed the widget after I went to the Time Machine - Troubleshooting user tip, here: http://discussions.apple.com/thread.jspa?threadID=2057525. Also went to Using TIME MACHINE with a TIME CAPSULE, here: http://discussions.apple.com/thread.jspa?threadID=2296894
I also renewed the DHCP lease, tried to do 'connect as' from the Sidebar window, also via go-> connect to server ("there was an error connecting to the server Timecapsule; Check the server name or IP address & try again"), go to Time Machine under System Preferences, select "None" for hard drive, turned off Time Machine, then turned it back on and reselect Time Capsule as the hard drive to backup (timed out), tried re-setting up the Time Capsule both automatic & manual (times out when reading TC configuration)., and finally, writing this post.
I am connected to the internet with the Time Capsule, and I am concerned about making too many changes, because I don't want to risk losing my internet connection, since that seems to be working fine. I was able to make regular backups until yesterday. Tracing my steps from when it used to work to when it 'broke':
1)I attempted (unsuccessfully) to mount the Time Capsule so that I could do a search on it. (I didn't realize at the time that I couldn't mount a wireless device.)
2)The only other thing I did was drag some music folders that I wanted backed up next to my sparsebundle backup (which I can no longer see, because the Time Capsule is no longer accessible via the finder) only to get the spinning ball with the copying window, which I couldn't force quit unless I quit the Finder. So, I force quit, rebooted, and repaired the disk/permissions with disk utility.
Did I do something wrong by dragging & dropping my files over trying to use it as a backup AND a an external HD? Or trying to mount the drive? Or maybe since adding several gigs of music, I took up too much space & now don't have room for a backup? (In which case, I need to access the drive & erase the music, and start over: if only I could SEE it I could do that.)
I am still doing searches trying to see what I need to do; I haven't yet re-set it, due to my concern about my internet connection, which could potentially prevent me from getting any information to fix it. At this time, I am not sure if this is a Time Capsule, Time Machine, or Airport issue. During the time that I have been writing this, the red check changed to 'connecting' but then the 'delayed - Time Machine is not available' message came back up
TIA

Reboot the network in correct order.. modem.. router/TC.. clients.. 2min gap.
This is just standard windows.. woops, Mac OS networking now.

Time Capsule "looking for backup disk" problems, running Lion on 24" iMac

Hi,
I'm having problems with my Time Capsule. I can't get the backups to run for about a week. The backup just says "looking for backup disk" for ever. This is a first gen Time Capsule, and it's still working fine for two MacBooks in the house. I have all the Apple updates installed, and I'm running 10.7.2. In Preferences, Time Capsule, I can see the available/of space and there is plenty left. It's not showing any Oldest and Latest date info for backups.
If I go to "select disk" and choose the Time Capsule, I'm prompted for the password. When I press "Connect", the message changes to "Stopping Backup" and this will run for ever. I have plenty of disk space available, have repaired permissions, have booted in safe mode, reset pram and nvram and probably a few other options to no avail. I can enter the Time Machine and see all of my backups without problem.
As a side note, I have also noticed instability whereby various programs have been 'not responding' of late, and need to be force quit. Once that happens, the iMac won't properly shut down and restart; I usually need to how down the power button.
Thanks in advance for your help.

I'm having the same problem. Anyone have a fix?

Migration Assistant from a backup disk...

Is it possible upon first booting (or subsequently) to import the user account from a FireWire disk? I mean, it is so easy to import from another Mac with Migration Assistant but is there no similar way to import from a backup disk?
I'v done it the hard way by dragging and dropping the files but it seems like the permissions are always messed up and need time-consuming repair. It is also very difficult getting the preferences to be accepted while the application is already running.
Hoping there is an easy way, because I prefer to wipe the hard disk and install freshly.

no, MA will not understand that. then you'll have to migrate things by hand. check out this [link|http://discussions.apple.com/message.jspa?messageID=6185507] for a list of things to move.

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.

Hi
One Must NEVER move or alter any folders named
• iMovie Event's - or -
• iMovie Projects - or - alike
on DESKTOP/FINDER - Ever ! - ONLY Within the iMovie Program ! else all connections are broken and hard to impossibly to mend !
but rather do as described here under
Moving Event's and Project's
Connection - Either connect one Mac in Target mode to the other via FireWire. Or use an external hard disk !
(Target-Mode - Start one Mac e.g. laptop - BUT keep T-key down during full up-start - Now a FW-symbol is jumping around the screen and it will work as an external hard disk when connected to the other Mac)
A. The External Hard Disk - MUST BE - Mac OS Extended (hfs) formatted to work for Video. UNIX/DOS/FAT32/Mac OS Exchange works for most other things but not for Video whatever program is used (iMovie or FinalCut)
B. Should be a FireWire one as USB/USB2 performs badly to me and especially when filling up
C. Do never Move or Alter any folder named
• iMovie Event's - or -
• iMovie Project's
on DeskTop/Finder - as this will result in iMovie losing connections to them and repair can be anything from hard to impossibly
D. Moving and Copying must be done within iMovie application and Events to Events - and - Project's to Project's.
E. Moving Project's to Event's - Do not work for me - I have to export project as a QuickTime movie then Import this into Events.
Event's window can show two faces
Like this
or like this
from one hard disk Event - You can move it to the other hard disk
You can not (at least not me) move Event to Project or other way around only
Event to Event and Project to Project

Backup disk image cannot be mounted.

I have tried and tried to get Time Machine up and running with no success. It has given me several error messages...the latest of which is "The backup disk image could not be mounted."
I can see the disk in my "shared" finder window, make changes but every time it tries to backup, I get an error. It DID backup once when i first got it but have not been able to do so since. I have restored to factory settings and tried all kinds of suggestions from posts...can anyone help?

Welcome to the discussion area, Stacie!
There a number of possible reasons why you are having difficulties, so it may take a number of steps to try to get this solved.
First, let's make sure there are no permission errors on your Hard Drive. To do this:
Note the name of the hard drive on your computer. If you have not changed the location or the name, it will be at the upper right of your screen and the name will be Macintosh HD
Open Hard Drive > Applications > Utilities > Disk Utility
On the left side of the Disk Utility window, click to highlight the drive that has exactly the same name as your hard drive on your main computer screen.
Now, look for a button that says "Repair Disk Permissions". Click that button. It will probably take 30-45 minutes for the check to complete.
When the process is complete, restart your computer.
Click the System Preferences (looks like a gear) icon on the dock and then click Time Machine
Click the name of your Time Capsule to highlight it
Click Use for Backups
Wait a few minutes, then click the clock shaped Time Capsule icon at the top of your screen and click Back Up Now.
You will probably see "Preparing...." for a long time. Let it run, even if it goes for 45-60 minutes. If it still says "Preparing" after 2 hours" click Stop Backup Now and post back for more steps.

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,
Neil

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.

The backup disk image "/Volumes/3TB Seagate Expansion Drive-1/Toby's MacBook Air.sparsebundle" could not be created (error (null)).

Hi all,
Recently moved into a new place and now have my external HDD plugged into my iMac as a backup.
Just went to backup my MacBook Air, which has used the drive previously, but always through USB.
Now trying to backup wirlelessly so I do not need to remove from my iMac, but got this message:
The backup disk image “/Volumes/3TB Seagate Expansion Drive-1/Toby’s MacBook Air.sparsebundle” could not be created (error (null)).
Have tried to reset without success. Any suggestions?
Thanks

You might want to consider starting a new discussion. Since this one is marked solved, less people are likely to look at it. You can link to this one.
The same error message? Try hooking your backup drive to your computer and run Disk Utility Repair Disk and Repair Permissions.

The Backup Disk Image Could Not Be Mounted

I've successfully installed Time Capsule on my network and it is working correctly. I can access it via wireless and choose it from Time Machine. The initial backups go well, and I can access them if I enter Time Machine. However, at some point, it creates a disk image on my desktop and then returns the error The Backup Disk Could Not Be Mounted. The only way to restore everything to normal is to reboot.
I've already dismounted and remounted the drive, so permissions don't seem to be the problem.
Can anyone tell me what's going on and how to fix this??
Thanks!

I have a similar problem. At first, TM worked with both my machines. Now it works with the mac air but not the ibook. I get the Backup Disk Image Could not be mounted error message.

Time Machine: Backup Disk Not Available

I realize there are a few topics floating around about this issue, but I'm still not finding a solution. Not sure if my situation is different than the others but figured I'd take a shot a describing my scenario in a new thread and seeing if it generates any new ideas.
I have a 2TB Seagate external expansion drive connected to a MacMini on my home network. The drive is formatted as Mac OS Extended (Journaled) and is not partitioned.
I have mounted the drive on my MacBook Pro 2.66/i7 running 10.6.6. I then go to the TM Preference pane and select the drive, enter the username and password for my admin account on the Mini. It indicates that it's preparing and then comes back a minute later with a Time Machine error indicating that the backup drive is not available.
I have an older MacBook Pro, my sons MacBook, and my wife's Macbook also on the network. Each of these Macs can mount the backup drive, select it in the TM Preference pane and successfully begin and maintain the TM backup.
I have created a second "test" account on my MacBook Pro. I have followed the same steps and have had no problems with time machine preparing and successfully beginning the back up account.
So - with those facts - I have had to conclude that there is something amiss with my main account.
Other steps I have taken on my MBP with my main account include:
* Deleting the com.timemachine.plist file from /Library/Preferences - restarting and trying again. No luck.
* Restarting into applejack and performing an "applejack auto restart". No luck
* Removing all timemachine related entries in the Keychain, running Keychain FirstAid. No luck.
* Reformatting the external drive on the Mini, repairing permissions and running a disk repair and starting all over again. No luck.
In each case above a restart was done before attempting to reinitiate the TM process.
So - with out blabbering on with any more details, I think it's clear that I'm at a bit of a loss as to what else I should try. I'm WIDE open to suggestions.

I resolved this issue just this morning (see below). This may not (or may) apply to your situation because yours magically corrected itself, but hopefully it will help somebody.
Environment Architecture: We appear to have a very similar system architecture to the one you describe. In my case, we have 4 macs all relying on Time Machine and a networked 1TB Time Capsule for backups. Each of 3 workstation macs share data from the 4th, which we use as a primary server. I ran into my problem when the Time Capsule filled up and stopped backing up our primary server due to lack of available space. All recommended solutions for freeing up space appeared time consuming, and because we do daily off-site backups through MOZY (we use Time Machine for simplicity of recovery for hourly backups) I could take the "easier" path of just reformatting the Time Capsule's data drive and start again fresh.
Problem identified: Per instructions, I used Airport Utility to erase my Time Capsule data drive, but thought I'd check my existing settings while I was there. Seeing the password prompt, and not remembering for sure what my password was, I thought I'd just reset it to what I wanted. Seemed benign at the time. When I started my 1st system's backup, I was prompted for the Time Capsule's password, and entered the new password. It accepted it as it should have, but then rejected the backup with a message indicating that I had provided the incorrect network account and password. The odd part was that it had originally accepted it, and even flashed the available space on the Time Machine preferences window. After much searching through these topics, I discovered that the password is stored multiple times -- some correctly and some not. Correcting the passwords fixed the problems.
Where to look:
http://support.apple.com/kb/TS2048
Mac OS X 10.5.3 or later: Time Machine - "Backup volume could not be mounted" after changing network volume's password
* Last Modified: October 14, 2008
* Article: TS2048
As it turns out, Apple stores that password in multiple places in your Keychain (don't ask me why!), even using the identical Keychain entry name. All I can presume is that one piece of the software looked in one Keychain entry, and another looked in a different Keychain entry. The passwords were different (one was my original password, and one was my new password). Once I changed them to the same thing on each of my satellite stations, they all worked again and Time Machine is happily chugging along on all workstations.

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.

HT201250 This backup is too large for the backup disk. The backup requires 1.42 TB but only 998.49 GB are available.

I am getting the error ¨This backup is too large for the backup disk. The backup requires 1.42 TB but only 998.49 GB are available¨ when I try to do a time machine backup. I have a Retina Macbook Pro and am only using 250 GB on the internal drive. My 1TB external drive that I am trying to use has been complete reformated (case sensitive journaled) and therefore completely empty. Any ideas why time machine is saying my drive has 1.14 TB when its capacity is no where near that?

Well, at this point I might recommend that you reboot your MacBook Pro while simultaneously holding down the Command - R keys and booting into the Lion Recovery Partition. There I would enter the "Disk Uility", highlight your Mac HD in the left hand column to select it and run "Repair Disk", and then run "Repair Permissions" twice. They may resolve the hard drive's confusion in Time Machine.
Hope this helps
