SHOULD WE CREATE A DISK IMAGE WITH NEW IMACS?

Doesn't this take a snap shot of your mac in case something later gets screwed up?

the best way to back up your mac is to use time machine. You need an external hard drive or time capsule to back up to. The external drive should be larger then the built in drive.

Unable to create restore disk image with Disk Utility

I've tried three times in order to create a restore image of the users' volume of my Powerbook. I followed exactly the procedure explained typing "man asr" in a terminal window. I booted the Powerbook in target disk mode while connected to my iMac G5 from which Disk utility was run. Every time the disk image creation failed with a log report like this:
Creating Image HOME_HD.dmg
Initializing...
Copying...
/Volumes/HOME_HD: Authentication error

Finishing...
Unable to create HOME_HD - Input/output error.
I don't know how my imported music could create such a problem to Disk utility, nevertheless I removed the incriminated song from the Music library but another one raised to be not accessible. Then I booted the powerbook from the supplied Tiger DVD too, and I got an error over the music file, something about an allocation that was 190 instead of 1, I got the volume repaired from Disk utility but the Disk image creation failed again without any hint because booting from DVD does not allow to save log file anywhere. Why on Earth I can't manage such a critical task as back up under Tiger while using Panther everything worked like a charm following the same procedure? Is anyone experiencing something similar?
Greetings

Hi Lee, thank you for your answer, indeed I've just read carefully your article few hours ago, while I googled the net to find some hints on my issue. I think that I've followed exactly the right procedure to make the back up image, and can't find what is wrong. Actually Disk utility Repair disk successfully repaired the allocation bit (whatever that means) of the music files but that wasn't enough to let the creation of the disk image. Quite odd that the music files where recognized as messed up by Disk utility only booting from Tiger DVD and not while the Powerbook was connected to an iMac running Tiger too.
I'll do further investigation during weekend.
Greetings

Create encrypted disk image with OS install disk utility.

I thought to make a full backup of Macintosh HD, and followed instructions in /kb/ht1553. However, every time I tried to creae an encrypted disk image, it barfed with "Failed - User interaction required". I assume it needed the encryption password, but for some reason was unable to display a prompt for this. Anyone know how to fix this? Thanks, Stephen.

Create an encrypted sparse disk image instead of from folder, mount it, and then drag & drop your files into ii.

Trying To Create Encrypted Disk Images With Disk Utility.

I am trying to create encrypted read and write Disk Images of around 2 GB to 6 GB with Disk Utility.
More often than not the dmg is NOT encrypted.
It seems very hit and miss . . . . most of the time missing!
Is this process notoriously unreliable or am I likely to be doing something wrong?

I think you have cracked it Niel!
I made another, unchecking the Keychain box, and it worked perfectly.
I have been using a password which is used for other items.
Now the .dmg has been created can I check the Keychain box and if so what are the benefits?
I have never understood what the Keychain does.

Can i create a disk image of my Imac 27 triple boot from disk utility: lion 10.8.3, win 7 and snow 10.6.8

I have created a well working triple boot system on my Imac 27, I7, 16GB, 3.4.Triple boot: Lion 10.8.3, Snow leopard 10.6.8 and windows 7.
They all work great. I would like to find the simplest way to make a image or a backup of the entire system.
I am thinking of creating a new image from disk utility image option.This from the main 2 To hitachi disk. The image option at the top should create a global image of the entire triple boot. I am not shure if this is possible. The differential/incremental option is not necesary. I can deal with that.
But, In case the disk utility option will not work, which software would aloud diferential/incremental backup for each partition
A software solution that would babkup all my partitions.
A single all in one image would be great but is that possible?
Any suggestion: please d'ont talk about vm solution or other subject like that. I am looking for a backup solution for my tripleboot...
Thanks
Luc

There are a few problems here, first Mountian Lion won't install on a 2006 MacBook, it diesn't meet the minimum specifications. http://support.apple.com/kb/SP654
Secondly you shouldn't install something purchased under one apple id onto another persons computer.

Can't create restore disk image

I want to create a restore disk image of my os x hardrive using disk utility. Everytime I try to create the image it says unable to create disk resource busy. Can anyone help me with this?
Thanks,
Matt

Hi carmat06,
first of all: WELCOME TO THE DISCUSSIONS!
How much hard disk space is available? Be aware that MacOS X needs the same amount of hard disk space for a temporary disk image as the final disk image will account for.
You should also create the disk image on a separate drive.

How do you create a disk image using Disk Copy?

Hello,
Is there any way you can create a disk image using Disc Copy? Is there a better way to create a Disk Image?
I would like to burn two copies of a 4.2 gig folder on my mac. I usually insert a blank DVD-R and then the mac asks if I would like to prepare it at which point I click "yes". An icon of a DVD disk appears on the desktop and then I drag my files onto this icon. It takes a few moments to create the disc image and then I click "burn". However, after the disc is burned the disc image disappears and I have to start all over again if I want to make another copy.
How can I save this disc image? If I could save the disc image, it would enable me to burn a second DVD right after the first without having to create the disk image all over again. This would save a lot if time.
I am using OS 10.1.5
Thank you for any suggestions

Thanks Niel for the info about creating a Disk Image with the Disk Copy utility in OS 10.1.5
That worked however when I insert a blank DVD-R, the disk image still has to be copied to the DVD-R buffer and then it can be burned. And so this doesn't really save any steps - the "copying into the buffer" step still has to occur whether or not you have created a disk image of your files. So creating a disk image doesn't really shorten the process of burning multiple copies of a DVD.
I will try to describe the steps more clearly:
Two of the three steps for creating a DVD (steps 2 and 3) are very time-consuming:
1. put blank DVD into the drive (a DVD disk icon quickly appears)
2. drag files onto this icon (this step takes a long time as the files are copied into the buffer)
3. choose "burn" (the actual burning also takes a long time)
I was hoping that when I create two or more DVDs of the same files, I could first create a Disk image so that when I create the second DVD, step 2 could be skipped. That does not seem to be the case - the disk image still has to be re-loaded. And so I think I will not bother with the Disk image idea - it doesn't seem to be necessary or helpful when burning DVDs to backup data.
Thanks for your suggestion.

Can't create disk image with Disk Utility

I just upgraded to OS X Mountain Lion and i can no longer create disk images with Disk Utility in order to store encrypted data.
The operation fails and ends with the post :
Failed to create disk image, error:
hdiutil: create failed - Resource busy
I use three Macs with Mountain Lion, and this problem occurs only on one of the three.
I check the disk, repair permissions and did a reset of the PRAM. I even did a reinstall of Mountain Lion, without success.
But curiously, using a new user account, I was able to create a first disk image. But no one after.

Launch the Console 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 Console in the page that opens.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Click the Clear Display icon in the toolbar. Try the action that you're having trouble with again. Post any messages that appear in the Console window – the text, please, not a screenshot.

Unable to create an encrypted disk image with Disk Utility

Hi:
With our upgrade to Lion a few weeks ago, we're now unable to create an encrypted disk image of any type using Disk Utility any more. This problem occurs on 3 different machines, and is reproducible whether one is using an internal HD or an external FW HD. We can successfully create nonencrypted disk images.
This is a duplicate post with all the details here: https://discussions.apple.com/message/18469359#18469359
We haven't had any luck with a solution trying various permissions fixes as helpfully suggested by other readers in response to the error message # (-60008 error), so I'm hoping that someone else has run across a solution from the encrypted disk image perspective and that this tag line will generate some help.
Thank you!

Creating a mp3 disk image with disk utility

Hi,
I'd like to create a mp3 disk image with disk utility. In the end I would like to have a mp3 disk that plays in various stero system and macs.
But I want to add some additional files: a png file for a nice folder background of the dmg, a special image for the dmg, and some text files relating to the mp3s.
Is this possible at all? Is there something I have to observe creating the dmg?
Thanx for your help

Is this possible at all? Is there something I have to observe creating the dmg?
You need to know which file systems your "various stereo systems" understand. The default file system created on a diskimage when burning is a hybrid file system- HFS+, ISO-9660 with Rock Ridge, and Joliet with Rock Ridge.

Trouble creating a small disk image with Disk Utility

When I try to create a disk image using Disk Utility the size option for 2.5MB is grayed out and I cannot override this by manually entering the size I want. Ideally, I would like to create a 500KB-1MB size image to store 1 or 2 files that I want encrypted. Thanks for any help.

Choose a filesystem which isn't journaled to get the 5MB option; if you want to create a 2.5MB image, specify Mac OS Standard or MS-DOS. Some disk formats have a minimum size.

How do I create a disk image for windows 7, using a windows computer for USB bootcamp for mac?

Hi There, I have just bought a new 2013 iMac.
Spec: 3.4 GHz intel core i5, 16GB 1600 MHz DDR3 Memory , NVIDIA GeForce GTX 775M 2048 MB Graphics with OS X 10.9.4.
How can I create a 'disk image' from a windows 7 professional 64bit installation DVD using a windows laptop with windows 7 Operating system on? I want to transfer this 'disk image' (ISO?) to a USB ready for installing windows onto my 2013 iMac using bootcamp? I want to use bootcamp from a USB as I have no disk drive for the installation DVD on my iMac. I hope all this is clear.
Thank you. Joe

Yes, that's correct, at least not directly. You can create a blank disk image, copy the file to the mounted disk image, then burn the image to a CD/DVD.
Open Disk Utility and select Blank Disk Image from the New menu. Provide a name, Save location, and select the image size from the drop down menu. Leave Encryptions at None and Format as read/write. Click on the Create button.
After the image file appears the "removable" disk should be automatically mounted. If not double-click on it to mount it. A "removable" disk icon will appear. Drag the file you want to place on the disk image to the "removable" disk icon. The eject the "removable" disk icon. Now select the disk image file in the DU left side list and click on the Burn icon in the DU toolbar. Be sure to have a blank disc ready.
The above is actually the "long" way to do this. A much easier way is to simply insert a blank CD or DVD into the optical drive. The Finder will pop up a dialog asking what to do. Select the option to mount on the Desktop. You will now see a disc icon on the Desktop. Drag the file you want to burn to the CD/DVD, right-click or CTRL-click on the disc icon and select Burn from the contextual menu.

Copy Disk Image to New Disk Image

Hi. I have a disk image that is in sparsebundle form and has a total size of 9.61gb. When I mount the image, it results in a volume with 8.53gb used and 15.97gb capacity. Let's say that I wanted to move this entire volume to a new partition that is only 10gb in size. I should technically be able to do this since the files only take up 9.61gb, right? I can't seem to move it to a new volume, or disk image with a capacity less than 15.97gb. Is there a way that I can work around this? Basically I just want to create a new volume with total capacity approx 10gb and copy the files over. I tried using disk utility and restoring but I keep getting an error about not enough space. Any thoughts would be helpful, thanks!

See if you can reduce the size of the existing sparse bundle, per #A8 in Time Machine - Troubleshooting (or use the link in *User Tips* at the top of the +Time Machine+ forum).
Then you should be able to just drag & drop the sparse bundle to the new volume.

Problem creating encrypted disk image

I have just moved from an Aluminium PB G4 with 10.3.9, on which I successfully created encrypted disk images and sparse images.
I now want to do the same on a brand new WD My Book attached to the new Macbook Pro. I open Disk Utility and click New Image. But when I do so, there are fewer options than there are on the old machine. I only have
Save As
Where
Image Format
Encryption
No option for specifying size, no sparse option.
Also, if I try and create a dmg on the My Book, I get 'Unable to create "myfilename.dmg". (Invalid argument)'
Any suggestions? Thanks

V.K.'s suggestion worked. Thank you. But now I've found that I get the full set of options in Disk Utility too. Baffled.
In the week I've been using my new Macbook Pro, I seem to be getting eerily similar experiences, i.e. apps don't work right, then I quit and next time they behave themselves. Yes, I know it sounds weird.
Is this an appropriate place for me to ask further questions. Namely, what's the best place to find out about 1. read/write v. sparse disk v. sparse bundle? 2. partitions - should I used them, whatever they are? and 3. why are the bigger disk images called CDs and DVDs? If I want a passworded place to put files on my external drive, bigger than 500MB, is there any reason not to use one of the CD/DVD size options?
Thanks

Creating a Disk Image from Compressor Fails

Hpefully some one can help me out here.
Here's whats going on and I've tried this on 2 different systems (iMac 24 inch OSX 10.9.4,Nvidia GeForce GT750M 1 GB, 3.1 Ghz i7 Processor 1 TB Fusion Drive, 16 gigs of ram & a iMac 27 Inch OSX 10.9.4 Nvidia GeForce GTX780M 4GB, 2.5 Quad-Core i7, 16 gigs of ram 1 TB Fusion Drive, both have the USB Super Drive from Apple connected to them)
Both are running Compressor 4.1.2. I'm trying to make a disk image from a Apple Pro Res 422 HQ Quicktime 29.97 DF (drop frame, NTSC) The file is big since it's HQ so it takes a while to compress. I'm using the Create DVD preset in compressor and choosing " When Done: Create DVD" then below that "Output Device: Hard Drive" Because I want to have a disk image for back up and future burning so I don't have to tie up any systems doing this again.
It get's the the very end where it has that disk burning icon come up on the dock and then a warning comes up saying that there was a "error making the disk" and then that's it. I want to be able to create a disk image. Old compressor (3.what ever) works great, takes a lot longer to compress things but at least I haven't run into this issue with it.
I've had my destination set to the internal drive's, external drives .... you name it I've tried to save it in different places. I've added a background picture, removed it, nothing seems to work ....
Please help and much appreciated if you can help me out here.
Cheers
