Software :: Unable To Backup Via Time Machine / Backup Disk Image Could Not Be Created

May 1, 2008

I was a PC user who recently moved to mac. I have a macbook (intel 2.2GHz, 2GB RAM, 250GB HDD). When I was using PC, I backed up all my data to a network storage device (Buffalo LinkStation 250 GB connected to a 802.11g netgear router which is supplied by Sky) using a program called SmartSync Pro, which worked very well. Although I can connect to and mount the Share folder on this drive when the macbook is connected to the network, Time Machine will not back up to it. It wouldnt even recognise the disk on the network.

So I went onto the trusty internet, and found that you can get time machine to recognise the Share folder. (This was obtained from: my comment on their page at the bottom, number 66.

It recommended entering the following in to the Terminal: defaults write TMShowUnsupportedNetworkVolumes 1

Before attempting backup I have to go into "Network" and select the Share folder by double clicking on it. This seems to mount the volume. After this, it can be seen in Time Machine as a potential backup destination.

However, this method does not work for me. Time Machine "prepares" for a while, then gives the following message: Time Machine error. The backup disk image could not be created.

More internet searching took me to macosxhints which suggests creating something called a sparsebundle image on my local system. ( Have not tried this yet as I thought it would be prudent to seek some help first.

Apple have deliberately disabled the ability for Time Machine to back up to network attached storage, (except of course to their proprietory Time Capsule):

Is this because time machine requires a network faster than 802.11g?

Is this because a time machine backup to a network attached storage device is unreliable and the data is corrupted?

I dont want to shell out more cash for a time capsule. I would prefer not to have to hardwire to an external drive (which I will also have to go out and buy). Any thoughts?

Intel Mac :: Time Machine Error Message - Backup Disk Image Could Not Be Created

Jun 7, 2012

Error message "The backup disk image could not be created." I have tried everything I have found online in the community from TM full reset to changing my computers name. Anything else I can try? I am using a Seagate external HD with a connection through my router. I spent an hour on the phone with seagate and everything is ok on the HD end. TM sees it and it is mounted but cannot go any further

OS X V10.7 Lion :: Time Machine Backup Created On Mac With A Large Hard Disk

Apr 17, 2012

What if a Time Machine backup was created on a Mac with a large hard disk, e.g. 500GB iMac - and I buy a new MacBook Air with a small SSD hard disk e.g 128GB. What happens when I need to use the larger Time Machine file to set up the new MacBook Air? What happens to all those files that can't fit on the smaller SSD drive?

OS X :: Unable To Retrieve Lost File / Backup Created Using Time Machine

Mar 25, 2010

I have a file I alter once about a week, each time I alter it I save it as a new one, with a date included in the name.So I have a series of files something like

xxxxx march 13.numbers
xxxxx march 07.numbers
xxxxx march 01.numbers

This morning when I updated and saved the march13 file I accidentally saved it as xxxxxx march 13, not xxxxxx march 20 which it should have been. No problem, go into time machine and retrieve the march 13 file I thought.Its not there. Its not there from just before the save to any time it should be there !

Luckily I was able to retrieve it as I also have a once a week online backup so I went into the last one of those and retrieved "xxxxxx march13" which proves it did exist, it has a creation date of march 17 but if I look at TM for march 18 its not there - why isn't it in my time machine backup?

All the other files in that folder are as expected so the only thing that makes any sense to me is that TM hasn't been backing up over the past week or so but TM error logger shows no errors.

Software :: Time Machine Unable To Perform Backup / Backup Is Too Large For Backup Volume

Oct 26, 2008

I am getting the following error from Time Machine when doing my first backup. The startup disk being backed up, and the TM disk are both the same size.

Macintosh HD: 465.44 (total); 393.99 (free); 71.45 (free)
Time Machine: 465.44 (total); 465.29 (free)

The Time Machine error is: Quote:

"This backup is too large for the backup volume. The backup requires 472.7 GB but only 465.3 GB are available." why would this be? Other disks are excluded from the backup, and Time Machine is telling me that it needs more space than it actually needs. What should I do?

OS X V10.7 Lion :: Time Machine Backup Is Too Large For The Backup Disk?

Feb 10, 2012

my TM wil not back up! It states that this backup is too large for the backup disk. The back up disk requires 573.50 GB but only 225.23 GB are available. The TM needs work space on the backup disk, in addition to the space required to store backups. Upen TM perferences to select a LARGER backup disk or make the backup smaller by excluding file. 

Okay I;m sorry but obvioulsy I dont get this. I've never called Apple for help! I have every product they sell practically including Protection Plans I never used and no one will help me with this. My MAC is starting to have black or white screens and i can hear it running but it will not do anything so i have to reboot it, it screws up Enturage and then I have to rebuild that ( 5 times this year) anyway... I would like to back everything up- can I delete everything on the Time Capsule or Time Machine; god I dont even know what it is called Im so MAD... help if you can please. I'm going to have to take this to the genius people at the store and probably buy another computer but like before they will not save my files.

anyone have this problem? how can i fix it?

Intel Mac :: Time Machine Failure And Getting Message That The Backup Could Not Be Created?

Feb 20, 2012

I'm running Snow Leopard on an Intel iMac, everything up to date, and Disk Utility finds no error on any of the drives. I have a 1 TB external drive connected to USB (bus powered, with a power USB connection to a powered hub, so it has more than enough power). Time Machine fails with a totally unhelpful message that the backup could not be created because a folder could not be created. The external drive has 318 GB used, 481 GB available, so it's not disk space. Yesterday I repartitioned the external drive using the GUID partition scheme, creating a 750 GB Mac extended journaled partition "Time 1GB Tosh" just for Time Machine. I've been through the Time Machine Troubleshooting FAQs

OS X :: Unable To Mount Backup Disk Image?

Jan 6, 2009

for the past month or so my automated backups with time machine/time capsule have not been working. Every so often the following error message pops up:

"the backup disk image could not be mounted"

in troubleshooting, i have tried to mount the sparsebundle image directly but without success. from reading around a bit i can see that others have had this problem, and that one solution is to delete the sparsebundles and start again.

but that of course means losing all my archived backups, which i would rather avoid.

Applications :: Time Machine Taking Long Time To Backup - Changing Backup Time?

Dec 11, 2009

I have looked into this a lot already. It is to much that Time Machine backs up every single hour! It would be nice to set it to something like 3 or 5 hours. I have tried a 3rd party app to do this, but... If my computer was off or asleep when it was supposed to back up, it would get an error. It would not just do the backup when i turned it on or when it came out of sleep like stock Time Machine does. I have also seen a way to change the time incraments in the Terminal.(I am very good with it, not a noob) I have tried this and it screws up time machine completely. Maybe it does not work with the newest OS X. By the way... I have a 2010 MacBook Pro, got it 2 months ago.

Does anyone know a solid 3rd party app, that will work seamlessly. Or has anyone changed the time in Terminal and are currently using something different than 1 hour. There is a lot of examples online, but I would like the codeing that you literally used.

OS X :: Time Machine - Brand New Disk And First Time Backup Fails

Dec 6, 2010

So I bought a brand new WD 1TB Elements (USB) to use with Time Machine. I've never used a Time Machine before. I have a MBP13 with a 250GB disk, using the latest Snow Leopard, all updates installed. Formatted the drive to Mac OS Journaled (extended) and set it to use with Time Machine. Works until about 15-17GBs is copied over, than it fails:

1. If I start over it fails very soon after, no matter how many times I retry
2. No matter how many times I reformat it, it always fails
3. I tried one trick I googled - deleting the "inprogress" file - does NOT help
4. SMART status is verified
5. There are no problems if I verify/repair the disk.

OS X :: Time Machine Backup Disk Full - What Are My Options

Apr 6, 2008

I just got a message that my Time Machine external backup disk is full. I have another external drive I can use, but buying drives every few months is going to get expensive.

I was wondering what others are doing in this situation.

Is anybody archiving the Time Machine backup? If so, what software are you using and where are you storing your backup?

What kind of backup plans are you using with Time Machine?

OS X :: Can't Turn Time Machine Backup Disk Into Regular

Feb 8, 2009

I'm no newbie but this one has me stumped. I can put file onto a Time machine backup disk that I don't use as a backup anymore but I can't take them off. The Disk still has some backups on it that I would like to keep. But I would like to use the extra space for regular file storage. What gives. When putting a file on the disk it asks for the password but moving them to the trash it will delete everything in the folder but it won't actually delete the root folder. So my question is

1. Can I use the disk and keep the backups on it?
2. How do I get permission to read and write to the disk

OS X :: Restoring From Time Machine Backup Without Install Disk

Apr 8, 2009

I had to give up my Macbook Pro and am now going back to my Macbook. I have everything loaded on a Time Machine backup, but am having trouble getting to my Macbook. I bought a Leopard Install DVD back when they were released, but when I pulled it out I saw it is now scratched. Can I use a Macbook Pro Leopard install disk to restore my Time Machine backup to a Macbook? If not, is there any way to completely restore a computer from a Time Machine backup without an install disk?

OS X Yosemite :: Disk Won't Eject After Time Machine Backup

Dec 10, 2014

Each time im doing a time machine backup, the external drive does not eject, the icon becomes pale, but remains on the desktop. But when I did not just make a backup I can eject it normaly.

My disc contains two partitions, one with the backups. When my problem occurs the first partition is ejected but not the Time Machine one.

I tried to reformat the partition but the problem persists. My hard drive is a GDrive mobile usb 1 TO purchased at the apple store.
