Time Machine back up troubles.

I have run a 1.5 TB Ext Hard drive for the last 2 years, now my mac will not even recognize its existence let alone back anything up.

You have to sign out in System Preferences>iCloud and then sign back in again with the new ID. Your iCloud synced data will disappear when you sign out but reappear when you sign back in (give it time).

  • Having trouble restoring old files from an external Time Machine back-up to a new internal hard drive...HELP!

    O.k. So my main hard drive died on my iMac and I had to replace it. I have my old system backed up on my external with Time Machine. How do I access it to get my old files back on my new hard drive? I have read multiple forums and I have yet to find a solution. I was told that when I first turn the computer on and get to the third screen, it would ask me if I wanted to restore from a previous back-up. It did but it didn't show my external until I went through the set-up and got to my home screen. The drive showed then. It also asked to install updates...and I did. So everything is up to date. I have not turned time machine on yet because I'm affraid that if I do, it will erase my old back-up on my external. I tried using the Migration Assistant in Utilities and all I get is the spinning wheel when I tried to get that to work. So now I am here asking for help. I'm not very hopeful that I'm going to be able to get all of my old files back...  Any help would be greatly appreciated.

    Thank you for the video link. I did it pretty much exactly the way the young man explained. The one thing I didn't do was click "customize" as he does and unclick the multiple language support and he also clicks "rosetta" to support older programs. I wonder if that's the issue? The guys at Macmall told me that I would need to update the o.s. before I restored. I did that originally but have since (as mentioned before) erased the main drive. I noticed that when he does his install, his external drive does not show up on the list in which you want to install the o.s. on... should I unplug my external? I'm just trying to look at ever detail. I know the recovery file is there. The one thing it (the external) did say before I started posting here was "in progress". I'm not sure what that means? I promise I'm not an idiot. I consider myself an above average user. I usually help other that have issues... but I've yet to restore from a Time Machine back-up and I'm looking forward to learning how to do it.... the right way. I appreciate all of the advice. I have some pretty important files on my external back-up. I am really hoping that this is possible. I'm beginning to think the external is where the issue lies. The "in progress" next to the file name concerns me. I know there's a lot of data on the drive because it's nearly half full. So there's stuff there....

  • Trouble transferring iPhoto library from a time machine back up.

    Hi!
    I recently upgraded to the new OS and decided to do a clean install as my mac book pro is running a little slow. I did a time machine back up to save my files. When i went to put my iphoto library back it would not work as i needed the newest version of iphoto (i think i had the same one from when i got the laptop in 2009!). So i updated to the newest version and was able to retrieve the photos. The problem is i now have multiple copies of photos some with good and some with poor quality. I also have multiples of many photos and thousands of 'faces' grabbed by iphoto. Now with almost 40,000 photos its almost impossible to sort through. Any ideas how i can get my old, organized library back?
    Thanks so much!

    You need to restore the library from the TM backup by opening TM
    and doing it from within TM:

  • Trouble after installing a time machine back up on my new macbook pro

    The time machine back up actually worked well.  The issue is that the new mac is a macbook pro and the time machine install was from a mid 2009 Macbook air.   It is saying that the mail program cannot be used on the operating system.   I would assume it has installed an old mail program on my new machine and that is the issue.  The machine does not come with a cd to install the upgraded mail so how do I fix this issue?

    I accidentally bypassed the restore from Time capsule portion when I first started the computer so had to do this.
    You actually don't want to do this.  The hardware in your new MacBook Pro is significantly different from your 2009 Air.  You may end up with stability issues and potentially a system that won't even boot into the OS.  Podini's suggestion is best.

    Let's hope a couple things: that you have bootable clones of your drives also; that the backup drive for TimeMachine has over 3x capacity of the data you plan and are storing. I would also switch TM backup drives so you have a 2nd.
    Fragmented free space affecting performance happens when the drive is too full which may mean there isn't enough free space for a full backup set.
    1.5TB for backing up 500GB, while WD Green 3TB is $140 and WD Black 1.5TB is, about the same price.
    I'd be worried about the integrity and directory, and whether you can afford to lose that drive. Defragging is also a very slow operation. the ideal: to just clone a drive, or start over with another drive and wait. cloning TM volumes has not been done or has it? SuperDuper hoped to but I don't think they or Bombich's CCC made it there.
    Trouble with highly fragged is when free space gets to 20% normally, 1/3 or so though for TM volumes, and finding where and a chunk of space for the file being written. Does TM use large spare image files of like 2GB?

  • Can't restore new hard drive from time machine back up

    Looking for some help on this one....
    Briefly: iMac 24" aluminium early 2008 (model 2134) trying to upgrade the original 320 gb HDD. So I bought a WD Caviar Black 64 mb, 6gb/s 1Tb drive, intalled it pretty smoothly and then using an install disc restored it from a time machine back up. That went fine then I could not restart the mac (kernel panic). So i trouble shooted with an extended hardware test, disk repair and everything seemed fine. I reinstalled my old HDD again and worked perfectly so I figured my iMac doesn't like this Caviar (due to sata3 perhaps??) so I went and bought a Seagate barracuda sata2 1 TB 7200 rpm and repated the whole process. Again everything went super smooth until the restoring process ended and the iMac was restarted. Kernel panic again. Already tried PRAM, option key. Booting from the CD or my old drive is not a problem at all but from the newly installed drive (x2) ... Impossible
    Any thoughts ???
    Thanks

    Disconnect all peripherals from your computer except for the keyboard and mouse. Double check to make sure that you installed the hard drive correctly - http://www.ifixit.com/Guide/Browse/iMac#SectioniMac_Num20
    Select your imac then select hard drive replacement, and there are the instructions.

    my boot drive is my internal hardrive which is a 250 GB drive.  The drive i am using for TM is 500GB, but you are saying that is really too small.  TM, as i understand it, creates a copy of everything, and then subsequent backups record any changes that were made since the last backup.    and what do you mean "bootable clones"  and do you mean for my internal hard drive AND each of the 3 external hard drives that i have?  i'm using one of the three for backup using TM, and i am storing movie files on the other 2.  i work at a church, and we use many short films that we purchase online.  i then import that file into iMovie to give my volunteers a consistent second and a half of black before the clip and 4 seconds of black at the end of the clip. This provides smoother transitions, i've found, than trying to use most of the clips in their original form.  i then have been filing these away in folders on the other 2 hard drives.   Regarding the TM drive. Drive Genius is telling me that "the used space on the volume 02 [that's the name of the drive] is 25% fragmented (59.14% of total space).
    btw, Time Machine keeps:hourly backups for the past 24 hoursdaily backups for the past monthweekly backups for all previous monthsand the oldest backups are deleted when your disk becomes full.

    1st)  A fragmented drive is not evil.  It will not hurt anything.  At worse it might slow down reading a file.  However, as has been pointed out by others in this thread, who cares as this is a backup device, not a device you are going to be reading a lot.
    2nd)  The time you spend defragmenting the drive will far exceed the time you will save when writing new data to the drive.
    3rd)  Defragmentation will just increase your energy consumption, as all the reading/writing needed to move the files around in order to defragment it, will cause the drive to consume more energy than if it was just sitting idle waiting for the next hourly Time Machine backup.
    4th)  Defragmentation (if done frequently) may shorten the life of your drive.  Not mentioned in "3rd" above is that the extra energy used translates into heat, plus you are moving the read/write heads back and forth all of which affect the drives mechanical and electrical components.
    NOTE:  There are situations where having a defragmented drive is useful, but mostly it has to do with needing to stream media at a high rate of speed, and fragmented files can affect that.  However, a backup drive being used for incremental Time Machine backups is not in that category, and most home Mac usage does not need a defragmented file system either.

  • Time Machine back up to MyBook (2TB).

    When Time Machine backs up to WD MyBook (2TB), it transfers 100GB of my iMac HD (500GB capacity) each time. Consequently, MyBook is full. How do I get Time Machine to only add changes/alterations to the next backup?

    Thanks again rkaufmann. I have successfully deleted all files from MyBook. Unfortunately, I now have a large number of large files in my Trash that I am having trouble deleting. However, my initial problem is resolved. I will try to find a way of getting TM to only apply updates to existing files on MB.

  • Running more than one time machine back up drive

    I have a back up drive assigned as my offices time machine back up drive.
    I need to set up an off site back up drive too. I know that time machine will only allow a connection to one back up destination at once.
    What problems could i encounter if i set up a off site drive as another time machine drive, disconnect on site drive and connect the off site drive to back up.
    Thanks

    That will work just fine, other than the hassle of having to tell Time Machine every time you swap.
    Give the drives at least slightly different names (that's for you; Time Machine knows they're different).
    Each set of backups will be complete and independent. When you do a backup to either one, it will contain all the changes you've made since the last backup +*to that drive.+*
    The first backup after a swap may take a bit longer than usual, as there may be more changes to "catch up" with, but otherwise there should be no troubles.

  • Is it possible to change the read/write permissions on a time machine back-up of iTunes? I need to restore it, but old version is locked....

    Is it possible to change the read/write permissions on a time machine back-up of iTunes? I'm needing to restore it as my phone deleted half our playlists during sync  & am not seeing a way to unlock the permissions. I have the current version unlocked, but can't seem to get the backed-up version. When I click on restore I get a pop-up that says iTunes can't be deleted as it is part of the OS. I'm not even trying to delete, just restore the old version. Any suggestions?

    Hmmm, ok I'll give it a shot. I've always had the iTunes sync w/ my phone set up to only load selected playlists to the phone b/c there's a lot more in iTunes than I have room or desire for on my phone. A few months back I started having trouble w/ trying to sync everything & subsequently adding more to the phone than it could hold. The quickest thing at the time was to unclick the sync music option in iTunes so I could still backup the phone to the computer & not have a problem.
    When I asked about it during one-to-one session shortly after, they advised me to delete the music off my phone & then re-sync it to the computer, run a backup of the phone & redownload the music to the phone. When I tried this it ended up deleting all my playlists (but not my husband's) from iTunes. Irritating, but I've been rebuilding the playlists since. I had also unclicked sync music again & an Apple person told me the most likely best fix was to delete & reload iTunes completely.
    A few days ago I realized I hadn't backed up the phone to the computer in over a month so after deleting & reinstalling iTunes, & w/o changing anything (sync music was STILL unchecked) I ran a backup & my phone went from having 4 GB free space to being 2 GB over capacity due to iTunes trying to download the entire music library to the phone. I made a one-to-one appt again & it was suggested AGAIN that I delete all the music off my phone & then resync it to the computer & redownload the music. We did this (though a few random songs that had previously been purchased somehow remained on the phone), I got home, connected the phone & instead of the music that shows  as 'on my device' disappearing from iTunes it just sat there, so, as the guy had told me I MIGHT have to do, I threw all those songs showing in iTunes as being on my phone, in the trash so that it was completely clear.
    At this point I checked sync music, made sure the options were 'selected playlists only', checked the ones from my own list that I wanted (I usually have one playlist of comedians from my husband's folder that I also have on the phone, but didn't check it at this point). It uploaded all my stuff just fine, but for whatever reason when it saw that I wasn't uploading that comedy playlist any longer, it not only didn't upload it but proceeded to delete my husband's entire folder of playlists from iTunes. -_- I got on the phone w/ an Apple support person right away but he wasn't able to tell me anything .. basically said we'll have to rebuild everything. I asked about the possibility of using time machine, he said he's not qualified to answer that, so that's when I started looking around online & found, among others, the link I referenced a couple replies ago.
    I hope this all makes sense. It's been a long-term issue so I'm trying to go from memory as I figured to begin w/ that I had just made a mistake somewhere, so didn't try to document anything. Now w/ it having happened a 2nd time, I'm not sure if it was 'user error' or something else.......

  • Mountain Lion causing apps not to work, how can I downgrade to Lion without Time Machine Back-up?

    Since installing Mountain Lion, I have found applications that don't work.  I want to go back to Mountain Lion, unfortunately I had trouble with my Time Machine back up hard drive a couple days after installing Mountain Lion and I don't have any back up to work from.  Tried to go to App Store and redownload Lion from there under purchases, but I got message that said "You can’t upgrade this version of Mac OS X because a newer version is installed."
    I have another mac that I can download the Lion install package to and then drag it over to this computer, so the question is, Will I be able to re-install Lion over the upgraded Mountain Lion without any problems?

    You don't see drives when using a hardware RAID only the volumes.
    WD Green are not suitable for hardware RAID (or software RAID for that matter).
    USB2 and TimeMachine are a disaster waiting to happen. I've used SATA (internal) and eSATA (using SATA PCIe cards) trouble-free.
    I can't say I begin to understand your use or "choosing the install drive for the backup"
    Install what?
    You don't load TimeMachine. Maybe seems minor but that is not how to describe the behavior of software.

  • Can i do a time machine back to snow leopard from Lion?

    After hearing lots of good and bad about Lion, i've re-considered paying the 29 and doing an upgrade. Mostly because of the full screen two finger swipe feature. 
    would you agree that feature alone is worth the upgrade?
    if i didn't like it, could i do a time machine back to snow leopard no problem? I don't have any installation discs.
    Thanks for your feedback.

    Lion has lots of good features, but the trouble is it has lost nice features too. You can ONLY tell what you think after a week or so of use.
    "Going Back To Snow Leopard" is a LOT of work - you will have to use the DVD install disk that came with your computer to erase Lion and install SL from scratch. That means saving your valuables in SL first (Time Machine or some other external drive export like Carbon Copy Cloner). It takes hours of your day, but can be done.
    Lion needs a lot of care (adjustments) to make it behave the way you like it - it is REALLY different at first, but there are ways to make it behave a LOT more like SL by tweaking options in System Preferences and so on. It also takes hours to index - leave your machine on for 24 hours after you first install Lion - it will speed up a lot quicker that way.

    Csound1, William & Sig .... thanks for taking the trouble to reply. I fear you are right - I'll need a new disk. I'm booked in at the Apple Genius Bar in Bordeaux, France on Wed ... quite a challenge as my French isn't great! The current internal disk is 500gb, does anyone know whether I can upgrade my 21.5" iMac (circa Oct-2009 vintage) to a larger size internal disk, 1Tb or even 2Tb? I already have one external 2Tb drive and another one on order (I have masses of media stored and more planned as I've just taken up photography). Seems a bit of a pain managing with only 500gb internal storage. OR, can you advise me on how I can store all my photos on my new 2Tb external drive - I can't seem to figure out how to set the path for iPhoto to see them (I can't even figure out where they are stored right now!). Same with iTunes, how do I set the default storage to the external drive (I moved everything manually and then imported them all from the new drive - it worked but seemed very convoluted). Any advice on how to manage multiple drives gratefully received. And thanks again for previous replies.

  • I have 2 macbooks each with an account for me and one for my wife. I use one Macbook logged in with my account and my wife uses the other Macbook only loged in on her account. We both make regular time-machine back-ups each on a separate external disk

    I have 2 Macbooks each with an account for me and one for my wife. I use one Macbook logged in with my account and my wife uses the other Macbook only logged in on her account. We both make regular time-machine back-ups each on a separate external disk. Is it possible to update her account on my macbook using her external disk without overwriting my stuff on the same Macbook and vice versa?

    Time Machine does not do individual accounts. It records the complete drive. So if you were to use her TM backup on your Mac it would make your Mac just like hers. Both yours and her account on your MAC.
    Just copy the missing files over from her Mac to yours. If there are differennt programs on each then they would need to be installed on both.
