Fusion drive and backup/restore issues

Hi,
since I installed a fusion drive on my early 2008 iMac, consisting of an internal 256GB SSD and an (external FW800) 320GB hard disk, I occassionally run into trouble when system updates are pending. In the past, at worst the time machine backup couldn't be restored and I had to reformat and reinstall the system from scratch - which is not really comfortable!
Currently, running Mountain Lion, when I try to select the startup disk, it complains that Boot-Caches on the Boot-Helper-Partition cannot be created. Nevertheless the system starts fine (and runs fast ;-).
Before upgrading to Mavericks, I would like to know
- if someone else ran into similar problems with fusion drives, when updating/upgrading system software.
- Is it normal that a Time Machine backup cannot be (completely) restore a Fusion drive?
Yes, I know that having the harddisk part of a fusion drive externally is not recommended/supported by Apple - and my Mac is nearly 6 years old, but that would not explain why system updates/restores nearly always fail and sometimes the Time Machine backup drive has a broken file system (needed reformatting)! And I always checked the disks with Disk Utility prior to updating...
Any comments are appreciated.

You can file feedback here. The more who file the more the faster the issues may be fixed.
Also you shoud look on the CCC forums.

I am planning to buy an iMac 21.5 inch with Fusion drive and 16 GB RAM while i visit USA for a conference. My country of origin is India and the option of configuring to my need is not avaialble here in India. My concern is once i am back to India, will my iMac be covered by the Apple's Protection Plan if something goes wrong here in India?
I recently came across some posts regarding International warranty related issues for iPhone and iPad....hence this crossed my mind...
Waiting for response from the support group members...

Thanks Ralph
This essentially means that if my iMac develops some problem (both software and hardware) in my country (India), it will be completeley attended (even the whole system requires replacement) by the AASP in India...is that what you say?

Fusion drive and external data drives

How does Fusion drive behave if you have data on an external device? I just odered a new Mini and I'm a Logic user with hundreds of GB worth of data on an external RAID 5 exclosure. Will files stored on the RAID be copied to the Fusion Drive when accessed frequently, or will that functionality be strictly for the boot volume?
Thanks!

You can definitely create a Fusion Drive using an external drive to add capacity, and in fact it can be a great thing to do as the SSD will eliminate most of the latency involved.
The SSD will contain whatever the most frequently used blocks are, and these will moved from your HDD(s) onto the SSD to provide the performance improvement. This means you could potentially end up with any number of your working files on the SSD depending upon how often you use them (or have been using them recently). This is important to keep in mind; the SSD in a Fusion Drive is not the cache as a cache-disk, meaning that if the SSD fails you will lose data and have to rebuild your Fusion Drive from backups.
This will essentially eliminate the redundancy advantage of RAID-5, as while you can replace any HDDs that fail as normal, an SSD failure will render the volume unusable.
I'm actually currently interested in whether a RAID-1 of SSDs can be used within a Fusion Drive, as it could allow the SSD part of the Fusion Drive to be given redundancy too, in which case the setup would be safe as it'd be 2x SSDs in RAID-1 + HDDs in RAID-5, giving you one to two disks worth of redundancy. However I suspect it won't work, as I believe Fusion Drive just queries each disk to determine if it is an SSD, and of course an Apple RAID won't identify itself as such.

Fusion Drive and sleepimage

Hello,
if you buy a new Mac with a Fusion Drive, where does OS X put the sleep image? On the SSD or the HD?
By "sleep image", I mean the file that holds the RAM while the Mac is in hibernation mode. It normally resides in /private/var/vm and is named "sleepimage".
Markus

I would guess the SSD, if only because it will allow the Mac to go to sleep faster.
Also the few articles I've seen about Fusion is that all writes go first to the SSD, then some time later Mac OS X may decide to migrate the data to the HDD. But since the Mac is now a sleep, there is no later. And if the Mac needs to use the Sleep image when it is woken up, the Mac would recover faster if the SleepImage was on the SSD.
All of the above is total speculation. I do not have a Fusion Drive, and I have not read anything about where the SleepImage is stored when you have a Fusion Drive.
ArsTechnica.com has a very good article about the Fusion Drive.

If I buy a mac mini with a fusion drive and add windows using boot camp, can I make the SSD function be dedicated to the windows partition?

Additional information from Linc's post. Basically, only one additional partition can be added to a Fusion Drive and it resides on the HDD.
Do computers that come with a Fusion Drive support Boot Camp?
Yes. Use the Boot Camp Assistant to create a Windows partition and install Boot Camp. The Windows partition will exist on the hard disk drive, not the Flash drive, and is not part of Fusion Drive Logical Volume Group. 3TB Fusion Drive configurations need to update to OS X Mountain Lion v10.8.3 or later to install Windows 8. See iMac (27-inch, Late 2012): Boot Camp alert with 3T hard drive for more information.

Iphone 4s Backup - Restore issue

Hi,
I am using iPhone 4s with iOS 6.1.3.
I took backup in in Aug'13 and yesterday.
Issue:
Yesterday I upgaded to iOS7 and it was successful.
But due to some usage issue I try to revertback but haflfway it faled due to storage issue in my pc (C drive was not having enough storage) and all the data gone from iPhone.
So I freeup space and try to continue the restoration and I couldn't restore the backup ( i tried both and not working). In the mean time I lost all my data including the contacts.
Since yesterday I am having the iOS7 with no previous data.
Please help me to guide me to restore the iOS 6.1.3 backup which I took earlier prior to the upgrade.
Thank you for all to help me to resolve this issue.
Cheers
Senthilkumar

If you are trying to revert to iOS 6 from iOS 7, that is not possible.
If you are trying to restore your phone from a previous backup, and the data you are missing is not in that backup, then it can't be restored to your phone.
In any event your phone will be restored with iOS 7.

Question about backing up to an external hard drive and then restoring

I want to back up my iPhone to an external hard drive rather than to CDs/DVDs, and it isn't an option under "Backup." I thought this could be done by consolidating the iTunes library and then copying the entire iTunes folder to the hard drive. But now I've read some things that make me not so sure. Can this be done? And if so, how do I restore everything if need be? I want to have a way to backup/restore in the case of having to reformat the hard drive or if I switch to using another computer. I am using a Windows computer.

Your iPhone's backup, which is created and maintained by iTunes stores data such as most iPhone settings, email account settings, contact info, SMS messages, notes, recent calls, call favorites, photos available in your iPhone's camera roll (you shouldn't depend on your iPhone's backup alone for these photos, which should be imported by your computer as with any other digital camera), and 3rd party app settings and data created and stored by a 3rd party app.
It isn't necessary to backup your iPhone's backup. You can manually update your iPhone's backup at any time without syncing, and the same when connecting your iPhone with iTunes on another computer. With your iPhone connected to iTunes and without syncing, control-click on your iPhone and at the menu window that appears, select Back Up.
Maintaining a backup of your iTunes library is much more important - copying the entire iTunes named folder to an external drive or some other external media used for backup purposes.
Since the iPhone is designed to be synced with a supported application on your computer for contact info and calendar events, you should maintain a backup of the supported application on your computer for this data. Photos transferred from your computer to your iPhone are not included with your iPhone's backup, so these photos should be included with your computer's backup along with all other important data.
When syncing an iPhone with iTunes on another computer, only iTunes content on the iPhone will be erased first, not all data on your iPhone such as contact info and calendar events. When selecting photos to be transferred to your iPhone from another computer, all photos available on your iPhone that were transferred from another computer will be erased first. If you don't select to sync contact info and calendar events with a supported application on another computer, contact info and calendar events on your iPhone will not be touched.

Tried to fix spotlight indexing and lost my entire drive and backup; can you help me find them?

Hi,
I am in a complete crisis. If anyone can help me, I'd be very grateful.
I tried to correct my Spotlight indexing by using a combination of the sudo mdutil -E / , sudo mdutil -i on / , and sudo rm -rf /.Spotlight-V100 commands from the terminal.
I am not sure what happened, but the computer went into an interminable color-wheel and, when I shut down and rebooted after an hour or two, I found that both my main drive and my backup drive had severe problems.
DiskUtility volunteered to correct these. I ran it on my main drive and found that my entire directory appears to have been erased.
Disk Warrior cannot repair. Nor can TechTool. Both declare that the directory structure is now beyond repair (which they also say of my former backup clone).
My main drive now has barely nine files left - and a handful of empty folders:
file:///Volumes/Eric's HD/Library/Application Support/
file:///Volumes/Eric's HD/Library/Application Support/CrashReporter/
file:///Volumes/Eric's HD/Library/Keychains/System.keychain
file:///Volumes/Eric's HD/Library/Preferences/com.apple.TimeMachine.plist

file:///Volumes/Eric's HD/Applications/
file:///Volumes/Eric's HD/net/
file:///Volumes/Eric's HD/home/
Though I did not run any file repairs on the back up drive, it has also lost all of its files (it shows just one remaining
file:///Volumes/Eric's Backup/System/Library/CoreServices/boot.efi - whatever that is).
FileSalvage is now beavering away, attempting to scavenge some 350Gb of applications, e-mails, photos, iTunes, and movies (most of which it is unable to name). But these will all be unlabelled and randomly organised by extension type. These could take months to sift through and the list is almost certain to be incomplete. I have no other backups of my system apart from a two year old clone.
Please tell me. Is there anything I can do to get back my lost directory structure?
                       Might there be some use of an Undelete routine that might recover the directory alone and thus allow me to salvage either disk?
                        I don't even know what sort of extension to hunt for in order to attempt such a restore
                       - nor how I might drop it back into its correct spot on the volume.
All suggestions gratefully received.

Thanks, guys.
Yes, FileSalvage seems able to retrieve a vast jumble of unnamed "junk files," a tiny percentage of which are probably highly valuable to me. The problem will be finding them amongst the jumble. It could take weeks. ITunes files and MP3s are more promising, as it seems to have been able to reconstruct the files' names - and even cover art - from their metadata.
No. TechTool Pro wrote nothing at all. Sadly, though, I had allowed Disk Utility to reduce the number of threads or leaves or something in the volume directory, before I realised the gravity of the situation. It has thus made a very small alteration to my main drive (resulting, no doubt in the creation of those 9 system files and their containing folders). But the back-up drive had nothing further written to it since the apparent deletion of the volume.
I downloaded a freeware program called TestDisk which claims to analyse drive partitions. The partitions on each of my two physical drives (the internal and the backup clone) were not apparently affected - just the total loss of the volume directory structure on the boot partition in each case. So, would this be the wrong tool for the job? http://www.cgsecurity.org/wiki/TestDisk It does claim to be able to "Rebuild NTFS boot sector." I don't really know what that means. Can anyone tell me whether a rebuilt boot sector will enable me to recover a deleted volume directory structure?
Meanwhile, I am also running a trial version of Stellar Phoenix, which claims to reinstate "lost/deleted volumes." It claims to have "found 6 lost/deleted volumes" already - after five hours, during which it has scanned about 5% of my 1.5 T external drive. So I suppose it may well take days to finish scanning. Then, I expect it may ask me to buy a serial code in order to proceed.
Does anyone have experience with Phoenix, or understand the jargon about lost/deleted volumes? Once I've bought the full version, is there a good chance it will actually reconstruct the whole volume as it once was - or is it more likely just to scavenge scores of thousands of nameless file snippets as per FileSalvage?
I don't have a problem with paying the boffins at Stellar if they are actually able to save me months of sifting through random unnamed files in order to locate the ones I've lost.

RMAN Backup restore issue

Hi Guys,
I am running 2 node RAC 11G R2 on windows. I am taking the database backup by issuing the following command:
backup database format='d:\backup\DGtest\%U_DB' include current controlfile spfile plus archivelog ;

Is your database open? I think it should only be mounted.

Fusion drive and logic?!

hi all, im going to have a new i mac i7 27 inch and bought it with a fusion drive. i saw some articles that claim fusion drive isnt good for logic work??
please let me know if its true and if I now have to start worry
thanks.. and hope it was good decision to buy the fusion drive.

As a single internal drive, no... a 7200rpm drive won't help...
You need a seperate drive for your OS X and another drive for your samples...
If you were thinking about patitioning the internal 3TB drive.. Partitioning such a large drive actually slows down the performance of the drive... and trying to run everything off an unpartitioned single drive is not a good idea either... though better than using partitions.
Personally, I'd get the smaller internal ITB HD for OS X and Applications etc.. and then use the $150 saved to get a fast 7200RPM FW800 (using a Thunderbolt to FW800 adaptor) /USB3 (Though be aware often FW800 drives often perform better than USB3 drives because of the overheads USB3 places on the system) or Thunderbolt external HD and use that for your samples/projects.

Fusion drive and mac mini overall

greetings, i'm thinking about getting a mac mini to augment my macbook pro. essentially i'm thinking of pulling my itunes, etc off my MBP to the mini. does anyone have experience or feedback on the fusion drive. i'm not sure i need it, but sometimes building it out with features gives me a longer runway with the machine. any other feedback on the mini? i currently have a 27" thunderbolt monitor that i use with my MBP. regards...

Hi, I've read glowing reports on the new Minis, drawbacks are mostly HDMI issues, but a few even via TB to even Apple's Monitors. if you can wait maybe 3 months to see if Apple offers something other than HD4000 for graphics, I'd do that.
PS. Disappointed in Apple more every day.

DIY Fusion Drive and RAID 5

Hi everyone!
I have spent several hours by reading various forums but haven’t found any definitive answers.
I have a 12 Core Mac Pro with the following setup: one 1TB SATA hard drive that carries the system and applications. For the files and storage there are three 2TB SATA drives in RAID 5 controlled by Apple RAID card. I am going to install a 512 GB Samsung 840 Pro SSD drive in the optical bay and have initially planned to use it just for the system and applications, but am curious if the following is possible.
1) Is it possible to combine the RAID 5 array with the SSD and create a Fusion drive?
2) If yes, will it retain all the features of the RAID 5?
3) Should TRIM be enabled?
Thank you in advance!

TRIM directly addresses the shortcomings of having only garbage collection available. SSD controller manufacturers and designers (including SandForce, the controller manufacturer for OWC's SSDs), recommends that TRIM be used with their products. So does Samsung.
For example, here's a 2011 article from OWC describing how you don't need TRIM on their SSDs and how it can in fact hurt performance or reliability.
That article has been discussed here on MacInTouch before. In my opinion it's bad advice, and inaccurate in some of its assertions. It also ignores the recommendation made by SandForce to use TRIM with their SSD controllers. But even if one were to take that article at face value, applying that advice to SSDs other than OWC's makes little sense.
The reason I'm advising against TRIM is simply that it's yet another driver-level modification of the OS, and these always carry potential risk (as all the folks with WD hard drives who lost data can attest to).
Apples and oranges comparison, for a variety of reasons. The short of it is that TRIM is supported natively in all recent versions of OS X. The tools used to enable it for third party SSDs do not add a new kernel extension; they change the setting to allow Apple's native TRIM implementation to be used with SSDs other than those factory installed by Apple.
This shows that the 840s do work slightly better with TRIM than without, but the differences are (in my opinion) trivial, a 9% increase at best.
One of the major reasons for the skepticism that exists about TRIM is that so many people, the authors of both articles you linked to included, don't understand it.
TRIM is not, strictly speaking, a performance-enhancement technology -- though it is plainly obvious that most people think it is.
Though it can, in many circumstances, improve performance, there are also circumstances under which it will provide little or no noticeable benefit. Not coincidentally, a new SSD tested fresh out of the factory packaging is unlikely to show much (if any) benefit. Or rather, TRIM is providing a real benefit for new SSDs, but that benefit doesn't become measurable in terms of benchmark performance testing until every memory cell in the SSD -- including many gigabytes of cells hidden from visibility by the SSD controller -- have been written to at least once. Writing 128 GB of files to an SSD with a nominal capacity of 128 GB won't do it, as there are several gigabytes (exact number varies depending on the model) still unwritten.
Under real-world use conditions, having TRIM disabled means eventually having noticeable write performance degradation due to write amplification. It is far greater than "9%" -- it can be a 50% or greater drop in write performance, depending on various factors. Defining "eventually" is difficult because it depends on how the SSD is used. But given enough time and write cycles, it can happen to all SSDs used without TRIM, no matter how sophisticated their garbage collection algorithms are.
Under those same real-world use conditions, having TRIM enabled means that the SSD should almost never reach a state of having noticeable write performance degradation, as it should almost never get into a state where write amplification is happening.
I will concede that it is possible to design a lab test in such a way as to defeat the benefits provided by TRIM, but such tests do not reflect any real-world usage scenario I can imagine. Furthermore, those same contrived tests would put an un-TRIMmed drive into an equally-addled state even more quickly.
I would suggest reading through the rather lengthy previous discussions about TRIM. Here are a couple of my past posts that are most relevant to the current discussion:
A description of what TRIM is here.
I addressed some of OWC Larry's comments about TRIM use with OWC/SandForce SSDs here.

OS 8.1 - Trying to partition an external scsi drive and backup data.

Have an Apple PowerMac 6000 series minitower at work. It runs a program called 4D, that is a database we use to catalog images. Since I've been with the company, there has been no backup of the database, as an external scsi drive had died and never been replaced.
Since the system is running OS 8.1, I wasn't sure how I could do any sort of network backup, and in the end I managed to get a new 50-pin scsi 50GB LaCie External Hard drive with the 25-pin cable to connect to the PowerMac. Connected it yesterday, and it did appear on the desktop as you'd expect.
But when I went to point 4D to the drive, it didn't seem to recognize the file system. I tried erasing the drive, but it had the same probem. Norton Utilities is on the mac, so I tried replacing the partition. Specifically, I tried creating two partitions. One that's 40GB, that I could do 4D backups to. The other, the remaining space (about 7GB) so I could try to copy the entire drive to that partition and maybe even boot from it if the other drive failed.
However, the drive was still mounted when I tried to repartition and it ended up causing an error. I tried rebooting, and the drive wasn't showing on the desktop, but it still wouldn't repartition. Not knowing was else to do, I low level formatted the drive, told it to write zeros to it, and then create the two partitions. Given I was doing all this on a Saturday and didn't know how long it would take, I left it running in the background to check on Monday.
Anyone have any experience with OS 8.1? Is there a program like Carbon Copy Cloner that works with that OS? And any thoughts on what I'd need to do to get this drive working as indicated above? I started using Apple again with OS X, and it's quite a bit different than 9 and previous. Could sure use some help.

Hi, merkman2001 -
I would use the Apple utility Drive Setup (which comes with a normal OS 8.1 install) to initialize and partition the drive, rather than Norton or any other third-party utility.
As far as the format type goes, select Mac OS Extended when asked.
<hr>
Is there a program like Carbon Copy Cloner that works with that OS?
Generally such is not needed with OS 9 and earlier OS versions. All pre-OSX OS's and software can be copied using a Finder (drag and drop) copy process, and remain usable.
This means that the System Folder on the internal drive can be dragged to the icon of the external drive and dropped into it. Ditto any/all additional folders, those containing the programs and documents.
You should be able to successfully do a test boot using the freshly-copied OS on the external drive; this is the best way to verify the integrity of the copied OS.
Can't recall if aliases were used in OS 8.1. If they were, it may be necessary to 'fix' any of them used, since the pathname contained in an alias is not corrected when it is copied to another drive - it continues to point to the original original.
You can also copy the entire source drive to the external one in one action - drag the iccon of the internal drive to that of the external one and drop it in.
After Finder gets done copying everything (this may take some time, so disable any sleep mode or screensaver), there will be a new folder on the external volume - this folder will be named the same as the internal drive. Inside that folder will be a copy of everything that was on the internal drive, including everything left lying around on the desktop and anything left unemptied in the Trash (these will be placed in new folders named "Desktop" and "Trash" respectively).
In order to make that external volume bootable using the freshly copied OS, move the System Folder out of the folder it was copied into, so that it is at the root level of the drive, meaning visible in the window that appears when you first open the drive's icon.

How to? Working images on main computer drive and backup to externals?

Hi there---
Right now I work in Bridge CS3 and Photoshop and have a workflow and image management system that works for me. But I want to see if I can integrate Lightroom, which I just installed.
I skimmed Martin Evening's book and I am still not sure I can do the following:
Can I keep 3-6 months worth of images on my working computer drive, backing up regularly as I always do, and then erase them on my working computer drive while keeping them on my two backup drives? Or does the Lightroom database not allow you to work that way. My read of Evening is that he works entirely off the external disks. But I don't want to do that. My external disks are just for backups only and I want to keep it that way.
When I would need something from 3-6 months ago, then I'd want to be able to fire up the backup drives and retrieve.
Any suggestions on whether I can do this and how I would do this would be great!
Thanks, Paul

Thanks! Is there a "how to" posted somewhere about this?? I need workflow suggestions and I'm coming up blank.
Currently, I put a new yyyy-mm-dd-nameofshoot folder for every shoot which contains a folder with the original RAW files. I delete the bad ones in bridge. And develop the ones I want to level 10 jpgs in photoshop. I put those in a JPG folder. Sometimes I put other things in the same folder that I want to keep in there... like client invoices, retouched photos, uprezzed images, web galleries. I try to keep everything together under 1 folder and manage everything through my Mac OS interface... not through software.
My backup routine consists of backing up weekly to two external drives using Prosoft's Data Backup 3. I do a simple copy, not a sync or clone, which only copies new or modified files. If the files get deleted off my computer disk, they get kept on the backup. In this way, I clean my computer disk periodically and retain my backup.
I'm so happy with my backup system and kind of want to retain it, but also use LR. I'm worried that the database will screw up my system of working. But I'm attracted to the easy metadata entry and image search capabilities.
Any ideas would be appreciated!
paul
