Time Machine switches backup disk or does it?

Ever since I switched to Mavericks, I've been having the same problem on a MacBook Pro and a Mac Mini. I select an external hard drive as my backup disk. It then appears with the Time Machine icon on the desktop. Then, maybe the next time I start up or several times later, the hard disk appears on the desktop with its regular icon. When I then go to Time Machine preferences and select the backup disk, that disk appears twice, once with a Time Machine icon as the selected drive (although it has its regular icon on the desktop) and the second time in the list of disks with its regular icon. If I select that disk for the backup, the icon on the desktop becomes the Time Machine one. This is happening repeatedly. Any suggestions?

gthawk: You stated "When I then go to Time Machine preferences and select the backup disk, that disk appears twice, once with a Time Machine icon as the selected drive (although it has its regular icon on the desktop) and the second time in the list of disks with its regular icon. If I select that disk for the backup, the icon on the desktop becomes the Time Machine one. "
This is normal (with Mavericks). I have the same thing. What I found is that if you turn off TM or eject TM or reboot the Mini it may turn orange (USB icon) again or when you power it up again. However, if left alone when it shows the TM icon and the Mini powers down completely and then you power back up with TM still connected it will reamain as the TM icon and not orange. Everything appears to still wotk correctly no matter what color it is. It appears Mavericks TM is more touchy than ML was.

Time Machine:The backup disk ran out of space unexpectedly. .....

Hi,
I upgraded to Mountain Lion when it was released and yesterday I began getting this notice from Time Machine:
"The backup disk ran out of space unexpectedly. Time Machine will try to make more space available by removing expired backups during the next scheduled backup."
I have a one terra external hard drive with exclusively Time Machine. It says it has 3.4 gigabytes available, but isn't deleting old backups and making room for new, like before. I tried the "encrypting" solution, but it still keeps on giving me this message. Should I erase and format? If so, what option should I chose to format?
My Hard Drive has 240 gigabytes, so 1Tb should be more than enough.
Thank you!
Gloria

SuperDuper and Time Machine are two completely different backup utilities. If you want something like what SuperDuper does then don't use Time Machine. You have many other options that won't use up all the space on your backup drive:
Backup Software Recommendations
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
Synk Pro
Tri-Backup
Others may be found at VersionTracker or MacUpdate.
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files.
Do the following to erase your drive:
Erase a Drive
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.

Why is Time machine saying backup disk disconnected? Using MBP 17" Lion 10.7

Why is Time machine saying backup disk disconnected? Using MBP 17" Lion 10.7

Do you have an external drive connected?
If you do has it gone into sleep mode? There is a setting in the OS to put drives to sleep if they aren't being used. Energy Saver "Put the hard disk to sleep when possible".
Also most external drives have a built in sleep function that if they aren't being accessed for a period of time they go to sleep by themselves.

Time Machine error: backup disk image could not be created

Iet up my new time capsule day and it's working great. Now that I've got everything sorted out, I'm ready to do the initial time machine back up on it. I went into preferences, changed the backup location to my TC and clicked 'back up now'. Very quickly I get a message that the backup failed: "Time Machine Error - The backup disk image could not be created".
I've searched the apple support area but haven't been able to figure this one out. Can anyone help, please? This is an initial backup. (FYI, it worked great on my old external drive.)
Many thanks

I had the same problem. I installed my Time Capsule, fired up Time Machine and got an error that said "The backup is too large for the backup volume. The backup requires 436.8 GB but only 182.2GB are available."
Coincidently, these are the same sizes as the space used and the space available on my iMac's drive.
I looked in /Volumes and saw that the sparsebundle was being created on the local disk and not on the main disk. Trying to backup again gave me the "Time Machine error: backup disk image could not be created." message.
I poked around the forums, and found a post about the machine name setting in sharing. I decided to give it a look, and lo and behold, I did not have a machine name. So I gave my box a name, kicked off Time Machine again, and it worked.

HT3275 Time machine error, backup disk image "/volumes/data-1/.sparesbundle " already in use. I don;t know what this means, can someone help?

My Mac mini time capsule is showing an error Time machine error, backup disk image "/volumes/data-1/.sparesbundle " already in use. I don;t know what this means, can someone help?

I had a similar problem and I solved it as follows -
In Time Machine - > I deselected time capsule Data Disk as a destination.
Then I pulled the power plug on the Time Capsule, twiddled my thumbs for 15 secs, plugged the power back in.
Went back t Time Machine -> Re-Added the Time Capsule Data Disk as destination. And then tested by selecting Backup Now.
All went well and the backup picked up from before the problem.
BTW - I also have a USB drive connected to Time Capsule that is an alternate disk for Time Machine to backup.
In Mountain Lion the GUI lets you add more than one Time Machine backup destinations very easily so I think it a good idea to have redundancy.
Hope this helps.

Time Machine thinks backup disk is full but its not

I just purchased a new 1 Terabyte hard drive for backup. In the past I backed up both my internal Mac harddrive (250 Gb with 8gb free) and an external iOmega archive drive (DRIVE H 320Gb with 41Gb free) to a 500Gb Lacie drive. I purchased an iOmega 1 Terabyte drive (DRIVE G) because the Lacie drive was full. I went into Time Machine and changed the backup drive to the G one terabyte drive and did a full backup of my internal hard drive. When I did this I did not have the external H archive drive attached so Time Machine didn't back that up. I did it that way because I wanted to first backup the internal drive then do some work and then go backup the external archive drive over night. I plugged the H archive drive in, so it show up in the finder and then told Time Machine to Backup Now. It started the back up but right after doing the initial computations when it actually started backing up I got the standard error message that "the backup disk ran out of space unexpectedly..." I've double checked that the backup disk is set correctly in Time Machine to the 1Tb G drive and when I do a Get Info on the G drive it shows Capacity: 1TB, Available: 713.54 GB.
Is it possible something is wrong with the new drive? Can I test that?

Its funny how sometimes asking a question can prompt your thinking. As soon as I finished posting this I thought "of course Disk Utility". I ran a check disk and got the following error message:
Unused node is not erased (node = 107)
I did a restore which corrected the error. Turned Time Machine back on and its backing up the rest of my data now.

Time machine The backup disk image "/Volumes/Data/Freedom Book.sparsebundle" is already in use.

I am getting the following error message from Time Machine (backing up to my 3 TB Time Capsule):
The backup disk image “/Volumes/Data/Freedom Book.sparsebundle” is already in use.
I have no idea why this would be in use, because only one MBP has the name "Freedom Book". Any advice on how to resolve? Running Mountaiin Lion 10.8.1.

I had the same error. I unplugged my TimeCapsule for 5 min from power. Plugged it back in to power then waited 10 min for everything to comunicate again. Clicked on backup now and it worked. Must have froze up or something.

Time Machine Error: Backup Disk Image Could Not Be Mounted

Time Machine was working just fine with Time Capsule for the first two days, then today I got the above error message.
The drive and the backup image both show up in Finder. I can even copy files from the Time Capsule to my hard drive.
I just can't get Time Machine to backup to the Time Capsule, even if I manually hit "Back up now".
Any ideas what I can do to fix this?

I may have fixed this ... I renamed my TC to a shorter name with no space and no apostrophe - just a few letters. That seems to have cleared it up - at least for now. Time will tell ...

HELP- what does this mean- time machine error- backup disk image "/Volumes/time Capsule/ cheryl lynott's MacBook.sparsebundle" is already in use?

The last date of my back up was 10/4- keeps saying The backup disk image "/backup disk image "/Volumes/time Capsule/ cheryl lynott's MacBook.sparsebundle" is already in use?

HELP -- what does this mean -- .......
Often, this error can be corrected by pulling the power on the Time Capsule, waiting a few minutes, and powering the Time Capsule back up.

Time Machine says backup disk is full

My Time Machine backup disk (FreeAgent GoFlex Drive: 1TB) says it's full. I thought Time Machine was supposed to delete old backups to make room for new backups on an on-going basis. I don't see a setting for it. I'm fairly new to Mac, so forgive me if this is supposed to be obvious. I did see some "expert" in this discussion tell someone to "buy a bigger drive." That's just arrogant and not helpful. Someone else bought a 4TB drive and it solved their problem -- duh! What happens when that's full? Don't need the arrogance, just would like to understand how it works. Thanks.

TM does thining, until you are left with only weekly backups. Then it deletes those backups from oldeset to newest.
However, it WON'T always delete a backup to make room, as this depends on a few particular details, and also it won't delete the only remaining backup.
Your 1TB isn't really that large anymore, so I can somewhat see why even an 'expert' would suggest a bigger drive. Most internal drives around 1 TB these days alone.

Time Machine Error, backup disk couldn't be mount

I have a USB drive plug to my Airport Extreme and I use it for Time Machine. Today I had a message saying: "Latest Backup:Failed"
Time Machine Error
The Backup disk image could not be mounted.
The hard disk is there, I can drag, drop, copy, delete files on that disk. There's is a big file call Serge'siMac_001ec205f583.sparsebundle, the file does not seem corrupted, I could probably drag it to the Desktop. How can I mount the backup disk.

Time machine - "the backup disk image could not be mounted"

SInce a few days, I am unable to backup via Time Machine.
I always get the message:
TIME MACHINE ERROR
The backup disk image could not be mounted
I use an Apple Time Capsule and still have more than enough free space on it.

Help.....
Tks

Rosy,
*_"The Backup Disk Image Could Not Be Mounted" (Console - “Failed to mount disk image”)_*
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.
Consider each topic below separately. When one option does not resolve your issue, then move on the next one.
*Unmount the Backup Disk Image* (TC)
If, for some reason, you have manually mounted the Time Machine backup disk image (sparsebundle), or Time Machine failed to eject it after the previous backup, subsequent backups may fail. (Console - “Failed to mount disk image”… “Backup failed with error: 21”)
Eject the backup disk image (white drive icon) by either clicking the little Eject icon to the right of the disk image in the Finders’ Sidebar, or Ctrl-Click the drive icon on the desktop and select “Eject” from the contextual menu. Now try backing up again or launching Time Machine to view previous backups.
*“Disconnect All Users…”:*
If your Time Machine backup drive (“Backup of Users Computer”) is mounted on your desktop or in the Sidebar of the Finder window. then Time Machine may think the drive is already in use. Alternatively, if the Time Capsule hard disk has been recently accessed by a Windows machine, it may not have fully relinquished control. Do the following:
Open Airport Utility and select the Time Capsule on the left.
Click “Manual Setup”.
Select “Disks” at top of window.
Click “Disconnect All Users…” at bottom of window.
Close the Airport Utility.
Now try Backing up again.
“I got it resolved. Apparently it had to do with one of the files being open on the disk from the drive. I had browsed the disk with one of my windows boxes here and it must have left one of the folders "open". Anyway, I rebooted the TC and we are good to go now.”
*Proper Computer Name* #
Make sure your computer has a proper name. Go to System Preferences --> Sharing. Time Machine needs to differentiate your computer from others on your network (i.e. "Bills MacBook" or "Office iMac"). If the "Computer Name" field is blank, create a name. Realize that if this step is necessary, you will likely have to start the Time Machine backup process over again and do another full initial backup.
According to this article, [http://support.apple.com/kb/TS1760], Time Machine may experience problems if your computer name includes certain characters. Make sure the computer name only includes ASCII characters from the following set.
(0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ)
Once a change in the computer name occurs, you should stop and restart Sharing on the affected computer. Uncheck and then recheck Sharing in the Services list on the left.
Let us know if any of the suggestions above resolves your issue.
Cheers!

Time Machine problem: backup disk ran out of space unexpectedly

Hi all,
I'm having trouble with Time Machine. Each time it tries to do a backup, it errors out.
Here is the most recent log from TM Buddy:
Starting manual backup

Using file event preflight for Macintosh HD

Found 1702 files (741 MB) needing backup

Copied 111323 files (57.29 GB) from volume Macintosh HD.
Copy stage failed with error:28
Backup failed with error: 28
It usually errors out in the middle of trying to backup the very large "iPhoto Library (original)" file, so I went digging into this file back in time. About a month ago, I emptied the trash in iPhoto for the first time, and the size of the iPhoto Library file shrank from 87 GB down to just 1 GB. That seems rather extreme, and according to iPhoto, I still should have approximately 62 GB of photos remaining. The last completed backup that Time Machine was able to make had the library file at 800 MB. Even more strange, the current iPhoto Library file on my iMac is 83 GB. So I think this is the reason why TM is trying to make another complete backup of this file.
I'm guessing that if TM is able to completely backup the iPhoto Library file, the errors will go away. Does this seem like a reasonable hypothesis?
If so, then I'll need to delete files on the TM volume to make more room. At one point last year, I had tried splitting my monolithic iPhoto Library into 3 smaller libraries, and later merged them again under the current name "iPhoto Library (original)". These changes/instances of the libraries were all captured on TM. If I delete the original monolithic iPhoto Library file (named "iPhoto Library") on the TM volume, will I also lose my current iPhoto library (named "iPhoto Library (original)"? In other words, how does TM distinguish one file from another? By the file name? Or some other more permanent identifier?

The backup volume was full. That shouldn't happen, because TM is supposed to manage disk space by deleting snapshots as needed to make room for a new one, up to the last complete snapshot, which is never removed automatically. Normally, a snapshot won't be started if there isn't enough space for it.
First, I strongly suggest that you make a new backup (not necessarily with Time Machine) on another external drive. A single backup isn't enough to be safe.
One possibility is that you were writing other data to the volume during the backup. Apple recommends that no other data be stored on a backup volume.
If you've moved any files to the Trash on the backup volume, empty the Trash.
Sometimes a reboot will clear the error.
Otherwise, turn Time Machine OFF temporarily in its preference pane. Launch Disk Utility, select the backup volume, and run Repair Disk. That operation may take a few hours. If the volume is repaired successfully, or if no problems are found, try another backup.
If TM still isn't working right, boot into Recovery (command-R at startup) and repair the startup volume ("Macintosh HD," unless you gave it a different name.) Reboot as usual and try TM again.
As a last resort, put the backup drive aside and don't use it until you're sure you'll no longer need the data. Then erase it and start over. Do this only if you have at least one other backup device.

Time Machine: Choose Backup Disk

Hi All,
I am trying to run Time Machine for the first time. When I attempt to switch it on or choose Backup Disk; there is no disk or selection i can make for a location.
Is there something else i need to do??

Welcome to Discussions.
Time Machine will not back up to your internal disk. You need to connect an external hard drive for Time Machine to use.

Time Machine switches backup disk or does it?
