OS X :: Encrypted Disk Image - Any Way To Verify Backup
Jun 23, 2010
So my current backup strategy uses two western digital external hard drives. The first I have permanently connected to my iMac using Time Machine. On the second I use CCC to backup to every week and keep it in the trunk of my car as an offsite backup.
Just had a couple of questions to make sure I'm prepared for the worse...
- What temperatures can hard drives survive at? Is there a risk of it overheating in my car?
- I've read about some issues with CCC's backups. I'm currently backing up to an encrypted disk image - is there any way to verify the backup? If I just cloned the drive instead so it was bootable is there any way to encrypt it? And is Super Duper more reliable?
I have a 10 GB encrypted disk image on my macbook (type OS Extended (journaled)). I've pretty much filled up the space so I want to resize. I go into disk utility with the disk unmounted and 'Resized' it to 20GB. Then I mount it and go into the Partition tab. I drag the corner all the way down to fill up the space and hit Apply. It goes through the motions without error but it does not actually extend the partition to the resize. On the right next it then says something to the effect that the disk is read only and cannot resize the partition. The write status is read/write until I click apple....then it switches to 'Unmounted, read-only'.
Info: MacBook Pro (15-inch Early 2011), OS X Mavericks (10.9)
I've done all of this and it won't open. I double click on it, the default program to open it is diskimagemounter and nothing happens when I double click.(Mac OS X Lion 10.7.4)
I have to send my iMac 27 back to apple for replacement (flickering screen issue) and I would like to erase my personal information. How do I do that on a Mac? I have a Lacie Drive connected via Firewire 800 and have been using Time Machine for backups. I also want to make sure that I have a complete backup as well. I am new to Mac OS X

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: http://blog.imulus.com/george/software/using-leopard-time-machine-to-backup-of-a-network/)See my comment on their page at the bottom, number 66.
It recommended entering the following in to the Terminal: defaults write com.apple.systempreferences 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. (http://www.macosxhints.com/article.php?story=20080420211034137) 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?
So between today and yesterday I have just been doing some casual maintenance with my Mac Mini. I decided I would run the First Aid program in utilities just to make sure everything is doing well. I was just wondering what is the difference between the two options "Verify Disk" and Verify Disk Permissions"- what exactly do each of them do? It almost sounds self-explanatory but can someone shed some light for me?
I've ran all the verification tests on each hard drive I have and repaired them when needed. So far it has only been my external WD hard drive that needed to have a repair, though I didn't notice anything wrong with it prior to running the verification test. Basically, I'm just wondering what each of the functions do.

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.
I want to use Time Machine, but I don't want to have all my data sitting in the open on an external drive that someone can just carry away. Can I make an encrypted disk image, and have Time Machine use that as the backup volume?
The following error message just popped up: "The backup disk image “/Volumes/Data/Robert's Office iMac (2).sparsebundle” could not be accessed (error -1)." I'm running a late 2009 iMac; upgraded to Lion about a week ago. It seems to have done the Time Machine backups fine for the last week.The only other recent change was to reset my iCloud account so I could sync with my iPhone.
Recently I haven't been able to backup. Why this is? Not too sure. I don't remember changing any settings or anything recently but within the last 2 weeks or so I haven't been able to backup at all. When I start backing up it says "preparing backup" then an error message pops up that says "The backup disk image could not be mounted".
I'm just curious as to what everyone's backup strategy for Windows is? I've been exploring the options of the Windows XP Backup utility, but I also like being able to have a entire disk image with Winclone. However there's no way to back up incrementally with Winclone. I'm sort of mum on both options, or would like to know if there's a better option? So what have the other Boot Camp participants been doing for a Windows backup?
I get the following message when attempting backup - the backup disk image"/volumes/data/rod Henderer's computer (5).sparsebundle" could not be accessed (error - 1)
I use Carbon Copy Cleaner to backup. I've set it to backup to a sparse, rewritable disk image. If I, say, delete a file, then do another backup, will the file I deleted still be in the folder it was in, or will it disappear as if the backup was cleared and redone?
Two days ago my computer died and I haven't been able to get past the Apple screen since. I've tried starting in Safe mode, etc. that did not work. I just started up using my installation disk and got into Disk Utility. It says it cannot repair the disk and that I should back up as many files as possible and reformat the disk. How am I supposed to back up if I can't start up? I am currently creating a new image of the HD to an external drive but my question is if Disk Utility couldn't repair the disk, with the external drive copy also be problematic? How can I tell before I reformat the whole thing and start over?
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
I have a question about OSX 10.4.11 and secure deleting. My understanding is that even after secure delete has been used to erase a particular file, older fragments of that same file can remain on the hard drive. Assuming this also applies to secure deleting files from a mounted encrypted disc image (created using the disc utility), would I be correct in saying that even if file fragments remained, once the image is unmounted, those file fragments would be encrypted like everything else within the disc image. I guess what I'm really asking is whether, when one deletes a file from an encrypted disc image, that file data is moved outside of the encrypted data blocks into clean drive space. I don't see why this would be the case but was wondering whether anyone knew.
I appreciate one can always use the free space eraser within disc utility to "mop up" but I'm still interested about individual file deleting.
(Btw, this is my first post and as a courtesy, I did search the forums for this topic but didn't find anything. If I missed something in my search and this has already been answered, apologies!)
I have run the Disk Utility verify function against my system partition. It tells me there are minor issues that need fixing up and I should run the repair disk function, by booting using Command-R and using the Disk Utility to repair the drive.Problem is, when I boot using Command-R and select Disk Utility the partition is shown greyed out and the Verify and Repair options do not work.I think this could be because the partition is encrypted. The utility does not offer me the chance to unlock the partition with my passphrase.How can I repair the filesystem errors on this partition?
I'm trying to repair my hard drive. I restarted from the OS X Mac Mini install CD (holding down the letter C when I heard the chime), opened Disk Utility from the Utilities folder, selected my hard drive image, but the "verify disk" and "repair disk" options are grayed out. I'm at a loss as to how to proceed.
I'm running OSX 10.4.11 on a 12" PowerBook 1.5 GHz with 1.25 GB of RAM and an 80 GB HD.
When I run the disk Utility to Verify Disk, it ends with the message, "Error: The underlying task reported failure on exit." This happens if I run the Disk Utility from the hard drive, from the OSX installation disk or from an external hard drive.
The Repair Drive button is always grayed out no matter where I am running the disk Utility from, too.
So far, I haven't had any other unusual things with the operation, but I'm concerned that this could be an early warning of problems to come.
Has anyone else had this problem or have a clue?
I have cloned the entire hard drive onto an external drive with Carbon Copy Cloner. I know PPC systems won't boot from a USB drive, but I was considering booting from the install disk, re-formatting the drive from there and then re-installing from the external by running CCC from there. I hope someone will have a direct solution to repairing the drive without doing all of that.
Having a major issue: similar symptoms to others in the forum - with the fan and the computer not getting past the grey apple screen, I booted from the install disk and got to disk utility, at first all options were greyed out and I could not do anything, tried again a few times and finally got to the point where I could run the verify utility, never given the option to repair. When running the utility it failed and said I needed to repair by booting from the install disk and running the disk utility? Going around in circle here - any advice? I am currently running the Apple Hardware test to see if that shows anything...it has been a workhorse and I've NEVER had any issues with it.

When I go into first aid in disk utility, and click on my system drive, the verify button is grayed out. If I remembered correctly, I was able to verify my system drive before.
I haven't seen a response from Apple. When I go into iTunes it shows that my backup will be encrypted with a password. I have NEVER backed it up to iTunes, only to the cloud. When I try to disable the encrypt option it asks for a password that I have never set. Many others have said to try every password you've ever had for iTunes as well as your security code on your phone. Oh and why not "000" and "1234" while you are at it. None of these work. It isn't the end of the world for me because I still have the phone and it is backed up on the cloud, but what is the deal Apple? How can I get or set my password since I have never set it in the past?
The first method is really quick while the second method takes quite a long time. Do the two methods yield the same ISO file? In particular, I would like to convert a bootable CDR disk image to an ISO disk image.
Purchased a new 2T Seagate Backup Slim Drive and decided to encrypt my data on my MBP for the first time.
First mistake - chose a very complicated new 13-character ( including multiple special characters ). Have tried to reconstruct the password with no luck!
Chose to go with "NTFS" driver that Seagate has licensed on a limited basis from Paragon software because I thought the flexibility of backing up both Mac and Windows files might be useful - new Seagate Slim Drive is about 25% full after 1 backup.
"Erase and reformat" project (unable to source to date very little info regarding Paragon NTFS file encrypted, file issues related to Apple devices.

I'm doing an initial backup to a Time Capsule and I want to make sure all my data was copied successfully. Does Time Machine verify that the data was copied successfully or does it just send it and hope everything copied alright? I know this is the kind of question only the Apple developers would know for certain, but hey, sometimes folks on these forums are surprisingly knowledgeable so I figured I'd ask here.
I have encrypted my macbook pro hard drive with FileVault and now find powerpoint files attached to emails are rejected by some recipients, with the following bounceback message:"An email you have sent has been blocked.This email has NOT been delivered to its destination as it contains an encrypted or password protected attachment. Please resend without the password protected attachment and it will be delivered to its destination"Other file types (jpeg, pdf, word) seem to get through and resaving the PowerPoint file as PowerPoint 97 let it go through. The presentation is not locked or password protected.
