Time Machine Error: backup to large requires 523 MB but only 8.4 GB avail

For about a week now I am getting the following backup error:
This backup is too large for the backup volume. The backup requires 523.3 MB but only 8.4 GB are available.
Then the latest backup fails.
This makes no sense to me. My backup volume is 150GB external USB Buffalo drive. It has been working great for months now. Based on some information I read in another post I excluded my application folder that added another 15.2 GB not needed to backup. I also tried unchecking the box that warns when old backups are deleted.
I have read through many post but have not found an answer yet.
Any suggestions?

Thanks for the quick and accurate advice. Since I had never done this before it took me a while to figure out how to partition the drive as GUID. I did not understand I had to create a partition and click on options.
On Apple's Support website for OS X 10.5 Time Machine under Mac 101: Using Time Machine in Mac OS X 10.5 Leopard (see below) it should have information about how important it is to partition a new drive as GUID then how to do it. It just says I won't have to worry about backing up again. For me I had to erase all my backups - this time nothing was really important that was not on my main drive. It would have been good if I could have set it up correctly the first time.
Getting started
The first time you attach an external drive to your Mac OS X Leopard-based Mac, Time Machine asks if you’d like to use that drive as your backup location (you may need to erase the drive first). Choose yes and Time Machine takes care of everything else, automatically, in the background. _You won't have to worry about backing up again._

Time Machine Error, Backup to large - 496 avail and only 79 needs backed up

I have a 1 TB TM with 496.9 GB available (I already have 1 computer backed up on TM)
The second computer I want to back up has 80 GB used of a 500 GB HD.
Time Machine prefs show 496.9 GB available on TM and shows the back up will be 79.1 GB total.
But I get a error each time I try to back up saying " Time Machine Error, This backup is too large for the backup volume. The backup requires 614.1 GB but only 496.9 are available."
Two questions:
How can 496.9 GB be to small for a 79.1 GB backup?
Why does a 79.1 GB backup require 614.1 GB of space?
Thank You
Doug

Time Machine Error - backup too large

I haven't backup my Macbook Pro for more than 10 days. I was out of town for a week and then had to turn it in for repair to replace the faulty nvidia GPU (lost all display - see http://www.macrumors.com/2008/10/10/some-macbook-pros-affected-by-nvidia-gpu-fai lures/).
So I just picked it up from the repair facility and tried to backup and got this message:
"+This backup is too large for the backup volume. The backup requires 174.0 GB but only 106.3 GB are available.+
+To select a larger volume, or make the backup smaller by excluding files, open System Preferences and choose Time Machine.+"
My computer's hard drive is 200GB and my Time Machine is 500GB. Why doesn't it just do it's job and delete old backups to make space for the new backups? Does it no longer recognize that I have previously backed up my computer? I don't want to delete the sparsebundle and start all over.

I also have this problem after selecting the option to restore a new computer from a backup.
Hi, and welcome to the forums.
Do you mean you got a new Mac and restored the backups from an old one? If so, exactly how did you do that? If not, what do you mean?
I assumed I could continue using the backup with Time Machine on the new computer, but this does not work.
On Snow Leopard, you should get an option to make a new backup or "re-use" the old ones.
It tries to backup to a new name on the same volume.
Did you select the same volume in TM Preferences > Select Disk?
Has anyone successfully resolved this issue?
Yes, probably, but it varies depending on exactly what the situation is, and whether you're now on Leopard (per your profile) or Snow Leopard. So please clarify.
Have no Apple engineers helped?
This is a user-to-user forum. Apple does not monitor it for technical issues.

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 Error - Backup Requires 2,211,365.5 GB!

Hello - I have searched the posts and nothing seems to touch on this specifically - I have been using Time Machine successfully for months and this has only started to happen in the last few days.
I have a white Macbook, 10.5.6 with an upgraded 150GB hard drive. I do backups sporadically (once or twice a week), as I don't want to keep my Macbook connected to a hard drive and I find using the airdisk feature on my AEBS takes too long and slows down the network. This has been working fine for me for months, but now I get the following message:
Time Machine Error
This backup is too large for the backup volume. The backup requires 2211365.5 GB but only 125.5 GB are available.
I tried reformatting my disk (250GB hard drive) and the problem still arises. There are no external drives or anything connected to the Macbook at the time.
Can anyone help? I don't want to go out and buy a Hard Drive with a 3million GB capacity!
Thanks
Ian

If TM is seeing a ridiculous amount of info to backup like that (2 million gigs is probably not a real number I am guessing) it probably means you have file structure problems that are causing TM to count a folder infinitely in some kind of loop... like maybe a file link to itself that kind of thing.
A disk check usually repairs these sorts of problems and should alleviate your issue.
I believe you are correct and I would add that this case might require stronger medicine such as DiskWarrior to repair the directory structure, if that it the issue.

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 error - backup fails due to sparsebundle already in use

Since upgrading, Time machine reports backup error:
TIme Machine Error
The backup disk image ...sparsebundle is already in use.
Any thoughts?

Thanks russ. After the initial upgrade to Mt Lion, no backups have been made. Every attempt reports the sparsebundle error. I recently updated to 10.8.1 and a whole new set of problems have shown up which is having me question the wisdom of continuing to invest in Apple product.
I have decided to pack it in with regard to the timecapsule product, as it is just too unreliable, and certainly not worth the continued time and effort it has been taking to try and get it to work. I have instead gone with an online backup service, Crashplan. I have the backup service I am seeing and I am no longer frittering away valuable time on something that ought to just work.
Problem solved.

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 ...

Time Machine error- backup directory

Yet another person with the same error: Time Machine backup has been working just fine for about 2 months to a Time Capsule. Suddenly, all I get is "Time Machine Error. Unable to complete backup. An error occurred while creating the backup directory." No matter what I do, I get the same thing. I've done many of the things listed in other postings:
- turning time machine and laptop on and off (repeatedly!)
- clicking on the Change disk and re-choosing my Time Machine/capsule
- reinstalling the latest 10.5.3 update.
I don't know what else to do- I'd really rather not go nuclear and reinstall the whole dang computer. Help! Any other ideas (not cryptic, please, explain, for me and everyone else out there with this problem)?
Thanks

First make sure that the disk is still good. Use Disk Utility on it. Since I don't have a TC I'm not sure of the exact procedure. You may be able to do it over Ethernet.
If the top level directory checks out, then mount the sparseimage (fire up TM from the dock and then cancel out) and then use Disk Utility to Verify the disk image.

How to restore from Time Machine when backup is larger than HDD

In an attempt to upgrade my 13 inch, 8GB 2010 MacBook Pro (750 GB HDD) from Mavericks to Yosemite, the Yosemite install was stuck at "about a minute remaining" for hours (overnight). So I cancelled the install and tried again only to be stuck at the same spot. I took the mac to an Apple Genius Bar to have it looked at while it was stuck at that install step. They couldn't fix it and did a fresh install of Yosemite. Luckily, I had backed it up about a week before, so I wasn't losing a whole lot. I attempted to restore from the Time Machine backup using Migration Assistant (2TB external USB 3.0) of the latest backup but the estimated time to restore from backup kept climbing to more than 150 hours. Eventually it had an error message that there wasn't enough free space on the HDD (the same 750 GB drive that my backups were from). There was less than 100GB of free space on the HDD before attempting the upgrade.
How can I restore at least a portion of my Time Machine backup, like my Documents and Apps? I don't even mind going back to Mavericks so that I can use my computer again! For example, I need MS Office but I cannot use it on Yosemite if I do not first get my original backup working again so that I can unregister the current version (the product key is "lost" with my inaccessible backups!).
Most of the information I can find online is how to prepare for a proper backup, but at this point since Apple Genius did a fresh install, Time Machine has my only backup!
Any advice would be great!
p.s. This may be useful to know: I had several virtual machines from Parallels: Windows, Ubuntu, etc before I upgraded to Mavericks from Snow Leopard. Mavericks required an updated Parallels that I never got but I'm sure those VMs are hiding in my backup drive.

OS X Yosemite: Restore items backed up with Time Machine
While in Time Machine, press the key combination shift-command-C. The front window will show all mounted volumes. All snapshots should now be accessible. Select the one you want and navigate to the files you want to restore.
If you need to restore from a backup of the hidden user Library folder, first select a snapshot, then press shift-command-G. A Go to Folder dialog will open. In it, you'll enter the path to the folder. The dialog will help you by automatically completing the parts of the path when you start to type them.
The path begins with slash character ("/"). Enter that. The rest of the parts will be separated by slashes.
The next part is the date and time of the current snapshot. Enter a "2", and the rest of the date should be filled in automatically. Press the right-arrow key to jump to the end of the path. Enter a slash to start the next part.
Next is the name of the volume (usually "Macintosh HD" unless you gave it a different name.) Start to type that, then jump to the end and enter a slash.
The next part is "Users", followed by a slash.
Next is your (short) user name, which is also the name of your home folder.
Finally, enter "Library", then press return. You should now be in the Library folder. From there you can get around as in the Finder.

Time Machine says backup is larger then the actual disk

I recently had a HD die, I replaced it and restored from my TM back up. I then formatted the TM drive and am now trying to do a full back up however when I do I get an error saying that the back up size is 525GB but my HD is only a 500GB drive of which only 450GB are used.
I ran disk warrior on my main HD, ran disk utility to fix the disk and permissions. I formatted the TM drive and now I'm zeroing out the TM drive (hopefully that will work)
Anyone have any ideas why it would be reading the back up size wrong?
Thanks!

That's correct, as odd as it may seem.
Time Machine adds 20% to the estimated size of the backup, for workspace on the backup disk. That's usually not a problem, because a Time Machine disk should be much larger than the data it's backing-up; otherwise, there isn't enough room to keep old backups.
It varies greatly, of course, depending on how you use your Mac, but as a general rule, TM needs 2-3 times the space of the data it's backing-up to keep a reasonable "depth" of backups for you.
Short-term, you can "squeeze" a backup onto the disk by excluding something large (so the estimate is under about 410 GB) and run a backup. Then remove the exclusion and run another. Since the second backup will be much smaller, 20% of it will be much smaller, too, so it should fit.
Longer-term, you need a much larger HD; at least 1 TB.

HT201250 Time Machine error - backup disk is not available

A new external USB disk was installed and fromatted as per apple and manufacturer instructions. Time machine backup was initated but had to be stopped after 2-3 hours. Upon resuming using "backup now" function an error message reported - Time machine could not complete the backup. The backup dis is not available.

Never mind, I fixed the problem by removing a lock feature from my external drive.

Time Machine error - backup drive not mounted

Our family has 3 iMacs now running 10.5. One has a hard drive connected to it. The others are networed via a couple of Airport Extremes. The network is fine (all have internet). Time Machine is running fine on the iMac connected to the hard drive and on one of the others via the network.
But on the 3rd I keep getting an error that the backup drive is not mounted. It can mount it manually and see it (and its files) fine. The hard drive is configured so that everyone has read & write access. I've tried restarting it and resetting prams. I've tried connecting to the hard drive as a guest and as an authorized user. I still get the same error.
Any ideas? Thanks.

It seems to be working now. I trashed the old sparsebundle file and let it start from scratch. Wish I thought of that earlier .......

Time Machine error - backup disc image could not be mounted

I have a LaCie external hard drive attached to my Mac and (through Time Machine) there are several other macs, including my own, which back up to this device (through the network).
One of the other macs has suddenly started to bring up an error message when it tries to back up - "backup disc image could not be mounted". But my mac is backing up without any problems. I've tried switching the LaCie on and off but it still won't back up anymore
Can anyone help?

BTW--when I go into finder and click on my .sparsebundle, I get the following:
The following disk images failed to mount
Reason: Operation not supported on socket
