Time Machine backup disk not mounting after Snow Leopard upgrade

i recently upgraded from latest version of Leopard to Snow Leopard via retail disk 10.6.3 & then updated combo 10.6.5. Now the TM backup disc will not mount.

Exactly what happens? Do you get a message? If so, what?
Try a "full reset" of Time Machine, per #A4 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum).
If that doesn't help, the backups may be corrupted. Repair them, per #A5 in Troubleshooting.

Time Machine Backups disk not automatically unmounting after backup completes in Lion

I am using Time Machine over WiFi on a 3rd party USB drive shared as an AirDisk through an Airport Extreme router. Ever since switching to Lion (clean install), I have noticed that the Time Machine backup disk will not automatically unmount after a backup is completed. This creates a problem when my MacBook Pro comes back from sleep. Specifically, the WiFi notification icon in the Finder toolbar indicates that WiFi is connected, even though it's not connected to a network, and I am unable to connect to any networks for what seems like several minutes until the Time Machine backups disk disappears from the desktop and WiFi actually connects.
Since the disk was not cleanly unmounted, Time Machine then keeps complaining that the sparse bundle file is locked and cannot be mounted every time it tries to do a backup. I have to either disconnect/reconnect the USB drive physically from the router, or restart the router every time this happens to resolve the issue. That is getting really annoying to have to do every time. I suppose I could manually unmount the Time Machine disk after every backup but it's ridiculous to have to do that every time I want to put the computer to sleep.
Is anyone else experiencing this issue and is there a fix?

For others who might be having this problem - I was able to resolve it by connecting my backup disk to my mac via USB, completely erasing it, and starting over from a new backup. Disk Utility was not reporting any errors when I verified the disk, but I went ahead and repartitioned it and started fresh. The disk now automatically unmounts after backups complete.

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.

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:

* 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.

HT201250 Time Machine backup disk not found

I recently reconfigured my external disks, creating a 500GB oartition for Time Machine backup. thefirst time I set up Time machine to use that partition all went well. Seconed time it failed "cannot find backup disk."
This is a 24 inch, mid 2007 iMac OS X 10.8.2. I am using two external backup drives - 1T LaCie with 4 partitions and a BlackX removable adaptor with a WD 1T drive plugged in. Both are formatted Mac OS Extended (Journaled) In the view below the top "Time Machine" drive at the top is a duplicate of the last drive in the list.
If I select the top drive - I have the option to "Remove Disk" - NOT to "Use this Disk." So I have to select the bottom "Time Machine" drive. The backup will then run once but on the second try I get "Time Machine couldn't complete the backup to "Time Machine". Unable to complete backup. An error occured while creating backup folder." Whether I remove the top listed disk or not doesn't seem to matter, sometimes it finds the drive, sometimes not!
The BlackX is a USB connected directly to the iMac. The other partition on that drive contains movie clips and they run fine.
There is a backup folder on the Time Machine drive with six backups - however I have to "reset" the Time Machine each time to get it to backup. It craps out on the second try every time. Got me buffaloed! Any ideas?

Assuming you have nothing on your Time Machine volume that you need, erase that volume and Verify it from Disk Utilities. Repair if necessary. Then, go into the Time Machine Preferences and Remove the selected drive to use. Now, reselect it and try a backup.

Cannot access time machine, backup disk not available error code.

My time machine stopped backing up. It is a 2TB. I get error code -6584. and says backup disk not available. Coincidentally, I had to reset my time machine for a forgotten password about 6 days ago. Wi-fi works fine, but a few days later when trying to access old files throughout the time capsule I could not. Said my last back up was the day the time machine had to be reset. I have 1.79 of TB used..which is weird my computer is only 4 G and have only filled up 2.4 G of it.
ANy ideas?

We haven't seen report of problem with 6584 for a while. It generally means a corrupted backup. You need to do a verify of the back.
See A5 here. http://pondini.org/TM/Troubleshooting.html
This will take a very very long time if the backup has almost filled the TC.. so at least use ethernet connection.
You do have a problem.. the formatted capacity of a 2TB disk is 1.8TB.. If you have used up 1.79TB then sorry but you really need to erase the TC and start over.
The TM can fill up huge disks if you use parallels or dropbox or any dual boot system that has a virtual disk file.. TM will backup 20GB for every 1KB change. That file is hidden btw so you might not see it but I assure you it will chew up space.
I don't know what you mean by computer having only 4GB. That would make it rather ancient.. Surely even smallest SSD must be 64 or 128GB.

Time Machine and Disk Permissions + Compatibility with Snow Leopard

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".
My questions are:
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?
Thanks in advance for any advice you can provide!
Fernando

Why are you repairing permissions? It's a waste of time unless you have a specific reason to do it, and the warnings don't mean anything.
To verify your Time Machine backup, proceed as below.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
Drag or copy — do not type — the following line into the Terminal window, then press return:
sudo tmutil compare
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
The command will take at least a few minutes to run. Eventually some lines of output will appear below what you entered.
Each line that begins with a plus sign (“+”) represents a file that has been added to the source volume since the last snapshot was taken. These files have not been backed up yet.
Each line that begins with an exclamation point (“!”) represents a file that has changed on the source volume. These files have been backed up, but not in their present state.
Each line that begins with a minus sign (“-“) represents a file that has been removed from the source volume.
Files that you’ve excluded from backup, or that are excluded automatically, are ignored.
At the end of the output, you’ll get some lines like the following:
Added:
Removed:
Changed:
These lines show the total amount of data added, removed, or changed on the source(s) since the last snapshot.

I want to use my time machine backup to go back to Snow Leopard

I can't live without having my great old golf game (Tiger Woods PGA Tour 2003) readily available, and playable, which I always had on my iMac with Snow Leopard. Since upgrading to Mavericks - and using Parallels with Mac OS X 10.6 Server - I am told there's a color/display problem (something about 16-bit color) and I can't get the game to play even though it's the same computer, only upgraded to Mavericks. Parallels says it's an Apple (Mac OS X Server 10.6) problem but from what I can see the server version of this OS is exactly the same as the non-server version - at least insofar as the display/color/graphics is concerned - and Parallels either doesn't want to help (with an appropriate graphics controller) or can't.... so I'm left with having to go back to Snow Leopard from Mavericks. What a huge disappointment! Can I use - and how do I do it - my Time Machine backup of my Snow Leopard OS, apps, documents, iTunes, etc. to wipe out Mavericks?

Yes, the machine came with Snow Leopard but not sure where the install disc(s) are. Perhaps they got lost in the shuffle as we moved a few months ago. I do have a Snow Leopard install disc - can I use that and if so, is there a different way to do the install than if I was using the original install discs that came with the computer? Maybe I will jsut have to try it and see what comes up....
But for the computer's inability to play the game, I would have stayed with Mavericks. Now I'm installing a trial version of VMware Fusion but probably the results will be the same as for Parallels. I'll report back in a few minutes!

OS will not boot after Snow Leopard Upgrade

I have a MacPro (Intel). I just upgraded to Snow Leopard and everything appeared fine. However, after restarting my computer the OS will not load. A circle with a hash through it replaces the Apple logo and the apple's spinning wheel continues but all drive activity. I have tried to run the install again by forcing the computer to open the dvd drive then booting for the OS DVD but this has not worked. Has anyone experienced this and successfully resolved?

You have a five year old computer, so a failing hard drive at this point is not so strange. You have a couple of options you can try. Start with this one, but if it does not work you will have to erase the hard drive. I hope you have a backup of all your files.
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

Macbook pro will not boot after snow leopard upgrade

My GF has had a macbook pro since mid 2008. It's been running like a champ since I've known her for the past 3 years with no issues. It has/had OSX 10.5.8 installed. We tried to consolidate all our pictures from all our apple devices and realized she didn't have an icloud on the old 10.5.8 OSX. So I called apple and they told me to order and install the snow leopard OSX 10.6 first and then upgrade to lion etc after that, Well we got the disk yesterday popped it in to install and it's been a disaster.... the computer shutdown for what looked like a normal restart during the installation process and never booted back up. Attempts to manually reboot leave us locked on a grey apple logo screen with spinning gear indefinately whith the Snow Leopard disk installed during boot up. With the disk removed I get the flashing file folder with a question mark. I called apple support we tried all the PRAM and SMC resets and then decided that we should go to the Genius Bar once all those failed. After an hour and a half drive to the nearest genius bar we were told that the we suddenly had a hardware issue which just happened to coincide with the new OS installation.... I'm not buying it and am looking for some help. The macbook was running like a champ until we inserted a disk recommended by apple... Any takers?

Time Machine "Backup disk not available" error message since install Snow L

Since installing Snow Leopard my back-ups have failed, generating the error message "The back-up disk is not available." Last successful back-up was immediately pre-install of Snow Leopard. TM looks like it is backing up but in the end I get the error message. The wireless aspect for internet connect works fine so I don't think connectivity is the issue.
I am not real techie so insult me with basics. Thanks.

I have four macs using time machine on a single 1TB drive connected to Airport Extreme through USB. This morning I got the dreaded error-109 on Mac#1. This occured right after I had added Mac#4 to the bunch. While adding the Mac#4, I mounted my airport disk and then used time machine to select it for backup. I forgot to eject it after it had done the initial backup. That was when the error occured on the Mac#1.
Mac #1 C2D Mini 2009 SL 10.6.2
Mac #2 G5 DP L 10.5.8
Mac #3 MBP 2009 SL 10.6.2
Mac #4 MB C2D2006 SL 10.6.2
First I turned off TM on all of the Macs. I mounted the airport disk again, on Mac#1. I deleted the sparsebundle for Mac#1. I opened TM and selected the airport disk for backup. It is now backing up again on Mac#1. When it is finished, I will turn on TM once again on the other macs and see what happens. There is still a chunk of space left on the airport disk, about 680GB after all of the backups

Time Machine backup does not work after 10.7.2 update

Hi,
after updating to 10.7.2 time machine does not perform any backups on my time capsule (error-1). What can I do? Please help. Thanks.

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
 Cheers, Tom

Time Machine backup disk not found

Hello,
I have following set-up at home:
* A BELKIN router in the laundry room
     > This router is connected to the internet via my cable modem
     > This router broadcasts a wireless network, let's call it wifi A, troughout the house
     > This router is connected to 3 wired internet sockets troughout the house
     > This router is functioning perfectly
* A TIME CAPSULE in the office
     > This time capsule is connected to one of the above mentioned internet sockets
     > This time capsule is used as a hub, router mode is OFF (Bridge mode)
     > This time capsule does not broadcast a wireless network
     > This time capsule connects a printer, a NAS network disk and a Mac Book Pro (via a thunderbolt screen) to the router
* A Mac Book Pro
     > At home this MBP is always connected to the wired internet, via the tunderbolt screen and the macbook pro
     > Running mountain lion
     > Backups are done regularly via the time capsule, without problems
* A Mac Book Air (and here is where the problem starts)
     > Running Mountain Lion (although the below problem was already present with Lion also)
     > Always connected to the wifi A network
     > This Mac Book Air is also set up to back up to the time capsule, but here is the problem.
The problem is as follows: when the MBA want's to start the backup, it start's looking for the backup disk, but it can't find the disk. So it cancels the backup. It is very strange, because the Time Capsule itself can be found. If you chose "Select Disk" in the Time Machine Preferences, the time capsule shows up as an option. The time capsule also shows up in the airport utility and in the finder. In the finder, one can even browse to the previously created Sparse Disk Image of the backup on the time capsule.
If I want to make a backup, I have to do one of the following:
* Connect the MBA wired to the timecapsule via the thunderbolt screen.
* Set Up a wireless network via the timecapsule, wifi B, and connect the MBA to this network. Extending the wifi A network does not solve the problem!
Anybody has a solution for this problem?
Jan
PS Replacing my Belkin Router with the time capsule is not an option. The router is located in the laundry room (since this is where the cable connection is coming in) and I don't want to place a backup hard drive in this damp room. Also having the wifi broadcasted only by the time machine is not an option since it does not even cover half the living area.

thought I had a solution, but had misread your post... sorry

Why is Time Machine backup disk not available?

After being away for 6 week on vacation with the iMac turned off, but the Time Capsule left on, all backups have been "delayed" and a forced backup-now yields the following message:
Time Machine couldn’t complete the backup to “XXX-Time-Capsule”.
OSX 10.8.4
I've tried to re-select with password using the TiemCapsule utility
Any suggesttions?

Open Time Machine Preferences>click "Select Disk">click on the appropriate TM disk under the bottom window titled "Available Disks." Force a backup and see if it works. If this doesn't fix it reboot your iMac and/or Time Capsule and try forcing a backup again once the iMac and/or TC have fully booted up.
