OS X V10.6 Snow Leopard :: Time Machine "could Not Unmount Disk"
Jul 1, 2012
I have a Buffalo Ministation 1T (as my portable hardrive), been using it for about 3 months and works perfect, nothing wrong with it at all and time machine formatted it straight away. I recently got the Samsung G3 Station 2T (as a back up to the buffalo) and Time machine says "There was an error erasing the Time Machine backup disk SAMSUN. Could Not Unmount Disk". Then in disk utility when i click erase from (MS - DOS (FAT) To (Mac OS Extended (Journaled)) it says "Volume Erase failed with the error: Could Not Unmount Disk".
Info:MacBookPro, Mac OS X (10.6.8)

Update: "Magically," the backup is working over AirPort Disk. I'll chalk it up to a Snow Leopard ghost. I have been backing up to a WD My Book 1TB drive connected to my Airport Extreme router without any problems. Yesterday I upgraded to 10.6 (installed over 10.5.8, not a clean install) and have been having problems with Time Machine since. After the OS finished installing, I attempted to perform a wireless backup. Everything mounted properly, and it began a 10GB backup. When it got to around 5.8GB, Time Machine came up with a network error message (not sure which one exactly) and stopped the backup.
At this point I just connected the drive directly to my computer to perform the backup, and it did so without any hiccups. But now I can't even connect to the AirPort disk, let alone try to backup to it. Time Machine says it's not configured, and when I try to browse for my Time Machine Backup Disk it won't let me select it, even though the drive shows up in AirPort Utility. I've enclosed a screenshot of what I'm seeing. Does anyone have any tips to help me get this mounted and working again? This is not turning out to be as painfree an update as advertised.

My MBPro is getting cranky in a number of ways that indicate a reinstall of Snow Leopard is in order. After the requisite disk first aid check I attempted to run the installer only to get a dialog box telling me that the system cannot be installed because this disk is used by time machine. The MacBook disk is of course a source for back ups but not a back up drive. Even after restarting and explicitly turning off Time machine I get the same results.What do I need to set to allow the installer to run. The installer cd is a stand alone snow leopard install cd, not a machine specific cd.

For sharing my iPhoto Library among multiple users on a MacBook Pro running, currently 10.6.8, I have by a Apple Support guide created a disk image file, and mounted it for storing my pictures without permission issues.However, to account for future expansion, the disk image is made to be 100 GB, while current photo library size is approx 50 GB. Is there any way of getting Time Machine to backup the files within the mounted disk, rather than backing up the disk image file itself? So that the size of the backup at present would be the actual size of contents of the disk, rather than the whole disk image file itself? And furthermore, by copying a disk image file, will the actual files within also be backuped?

In order to use Lion’s encrypted (Core Storage) external drive feature, I needed to reformat an external 1TB drive with Apple Partition Map, as that works only with GPT. The only partition was HFS+J formatted and was used as Time Machine Backup, which I wanted to preserve.
Act I:
I connected the drive to another iMac running 10.6 which happened to have enough space on the internal HD. I read this article http://support.apple.com/kb/HT5096 , which describes how to copy the BackupDB just by drag and drop. In hindsight, that was a bad idea, I should have created a disk image like suggested elsewhere, but if Apple itself suggests it, it can’t be so bad right?
So I just dragged the whole BackupDB to random folder on the iMac (after enabling ownership), and apparently it copied correctly the dir-hardlinks, as the resulting folder had the same size.
It seems that the Finder activates a special dir-hardlink aware copying mode when one does this. This is also confirmed by the fact that the Finder will refuse to copy the BackupDB together with other files, you have to drag and drop the BackupDB only.
Act II:
I reformatted the external drive as HFS+J with GPT and activated ownership.. But now, when I try to copy the BackupDB back, it continues to count indefinitely the number of files to copy! I speculate that the special dir-hardlink aware mode is not activated, but what can I do? How can I trigger it? Is there some hidden command line tool which handles this?
The lesson I’m drawing from this is: use the method described in the article only if you copy the backupDB from your old to your new drive.

I have received warning from Disk Utility that I should repair permissions as several files show incorrect permissions and, more than that, my 750GB shows "769GB available".
1. If I use Command+R and rebuild the disk from a Time Machine backup, will permissions be reset or will the files just be copied as they are now?
2. Is there a way to verify the TM backups to check the files therein?
3. Suppose, just for the sake of an exercise, that I reload Snow Leopard; can I still use SL's Time Machine to read a Lion Time Machine backup?

I got SMART warning about my hard disk, I got it replaced by a shop, but said I would do OS restore myself. (cant afford cost )Thought it would be simple - but it is anything but. It appears my install DVD is damaged, so was not able to boot with Grey OS install disk - holding the C key.I managed to get iMac to boot up using the old disk - using firewire dock. However I was not able to restore old disk and OS to new disk, Due to IO read error.(this is why I had the SMART warning). So I am unable to get the OS on the new HD using the old disk or the DVD as these are both damaged. The computer is running, so I thought I would try buying and downloading LION - then using the migration tool . The download is still running after 2 days.I went to apple store, and was told that they cannot replace DVD , so I should bring in the iMac = and pay for the restore. Dont wish to do this. As I have the computer and OS running, is there anything I can do to get a time machine restore from another backup disk (USB).

I want to plug in my computer into my USB dock, automatically mount my external HD, have TimeMachine do its thing automatically (so far, so good), but then immediately after the backup finishes, I want the computer to automatically unmount the HD. This will allow me to close the laptop and go somewhere without having to constantly eject the HD everytime I unplug the computer.
So - what I need is a program / script / etc that will tell the computer to eject the drive as soon as TimeMachine is done backing up.

Running Disk Utility's Repair Disk function from DVD, how long should this take to complete with a 1 TB drive? It's been nearly 24 hours so far. I booted the computer from the DVD, and after verifying the disk was told the disk needed repair.

I cannot seem to set up Time Machine using Time Capsule on my MacBook Pro. Evidently when I initially set up AirPort Extreme, I failed to select it as the backup disc.

I get the message now and then when Time Machine fails to backup to external disk:
"Time machine could not complete the backup. Unable to complete the backup. An error occurred while creating the backup folder."
This periodically occurs even though the previous hourly backup was OK.

I'm low on internal hard drive space. Am using Time Machine. It appears that Time Machine is creating disk images in my downloads folder, taking up even more space. Is there some way to limit or stop that process and just use Time Machine to back up.

possible to back up all your data with Time Machine on Leopard and then install Snow Leopard and use Time Machine to restore all of your pictures/movies/music and the like?
I'm going to assume it's a no go since Time Machine is capable of a full system backup -- it may just turn your system back into Leopard?

I am a little new to Time Machine, so I was wondering if anyone could answer this? I am currently using Time Machine to backup my Mac. I am running Leopard and I want to move to Snow Leopard when it comes out. When i get Snow Leopard, I will perform a reformat on my hard drive so its a nice fresh install. My question is what options will I get when I get when I go to install it as I have Time Machine? I'll be honest and say I'll be happy to just copy across my iTunes, iPhoto, contacts and calender over to Snow Leopard and not worry about anything else (stuff like downloading Firefox takes seconds and isn't a problem). Is this an option? Can i just install Snow Leopard totally fresh, then connect the Time Machine drive and copy the iTunes (etc etc) folders/files/docments over to my fresh install?

I just tried and everything seems non-responsive or on a 2 minute delay. I use Time Capsule and Time Machine and things are just not acceptable at this speed.
Also, I don't think the archives are right. I used to have a ton of things on my desktop - most of which I cleaned recently by moving or deleting the files.
However, going back a few months in Time Machine, the only files that show up in my desktop folder/view are the ones that are on my desktop today. All the older, moved or deleted files no longer show up in Time Machine.

I have a Apple Time Capsule which is used as a Time Machine Backup Facility and also a Wireless Hub for File Sharing and Internet Connection. I've been using Leopard for a couple of years without any significant problems. The other day, I installed Snow Leopard and suddenly, I'm facing a number of different problems and errors regarding backups to the Time Machine with the Time Capsule.
First, I was facing problems with a Case Sensitive error and now that I have ejected the Time Capsule, the Disk Utility has come up with a different name altogether and now I have the added problem of disk space on the time capsule. I know I could re-format and start over but that would defeat the whole point of my backups. The Time Machine/Capsule should re-write over the old backups when making space for new ones but its just giving me an error about not enough disk space.

I finally upgraded to Snow Leopard. I have some older software and everything was working fine, so I delayed. I have an Intel 2 x 2.66 Dual Core. Now, I keep getting an error whenever I try to run Time Machine. So far, this is what I have done: Used disk Utility, Disk Warrior, then disk utility again (erased back up drive), then downloaded and reinstalled using the 10.6.8 combo update. Disk Utility again. Tried to backup and got the same error: The backup was not performed because an error occurred while copying files to the backup disk.
After reading online I downloaded and installed backup buddy (I think) Anyway, this is the error that it gives: Starting standard backup?Backing up to: /Volumes/Backup/Backups.backupdb?Backup content size: 91.4 GB excluded items size: 65.6 MB for volume Knight/Freelance?No pre-backup thinning needed: 109.60 GB requested (including padding), 364.91 GB available

The only way I can see my backups in Time Machine is by using the "option" key and selecting "browse other time macnine disks. However, there is only one Time Machine disk, only one backup appears in the list, there is only one backup directory on the Drobo where I put the backup and I can't find a backup directory anywhere else. HOw do I reset Time Machine so that it defaults to the "other" backup?

I had to have the old hard drive replaced on my macbook pro running Snow Leopard 10.6.8 operating system. It was replaced at the apple store. I brought it home and yesterday restored it from the last time machine backup of my old hard drive which was Friday.That appears to be the only backup on the external hard drive I've been using with Time machine.
Today, it gets an error message. "Time Machine could not complete the backup. This backup is too large for the backup disk"...etc.
It is almost like it is trying to completely back up the new hard drive even though it was just restored from it. Is it because it thinks it is a different drive or something because it is a new hard drive?I don't want to delete the one good backup that I have but, I want to be able to use time machine to back anything up.

My Macbook (late 2008 aluminum unibody running Snow Leopard 10.6.8) is having a plethora of problems - Spotlight won't return any results, I can't get any .dmg files to mount, and software updates can't be installed. Many of the solutions I've found involve running Disk Utility, but every time I try to open it, it crashes.
Here's the log file I get:
Process:Disk Utility [52987]

So finally I hooked up an external HD to my iMac 24 to use with Time Machine. My internal drive is partitioned into several sections and the system partition of about 80GB is supposed to be backed up to this eternal drive which is a 500GB, freshly formatted. Setup is easy enough. After Time Machine starts backing up it goes to about 100MB then it stalls. Essentially it keeps running, the turning clock symbol in the menubar is spinning but no data is moved.
At this point I can stop back up and then do click 'Back Up Now' in the menu at which time it will copy a few kb's and then halt displaying '2KB of 60.96GB'. I realize that there must be something on my HD it doesn't like to copy but unlike in my other backup app I don't know how to find that. The Console doesn't tell me much. I have done repeated Repair Permissions but it doesn't help.

Has anyone figured out how to change the time machine backup interval in SNOW LEOPARD?
i don't want a third party app or anything, i just want to go in terminal or textedit and set a new interval.
for any of you who are going to tell me to modify the com.apple.backupd-auto.plist file. i cant find one, and i believe this is unique to 10.6. there is a regular backupd.plist file, a -wake.plist, and -attach.plist, but none of them list the "start interval" key that i saw.

I like many of you Mac users am very interested in Snow Leopard. I'm wondering however, if I decide to do a clean installation, will I be able to bring back all my files with Time Machine like you could do with Leopard? (I remember when I first connected my Time Machine HDD to my current computer it asked me if I wanted to restore my data) Also, will my Apps also be in restored onto Leopard? Or would it just be my files?
