Time machine backup on harddrive (already has data) do i have to reformat? mac/windows

i want to backup my mackbook pro which has around 300gb
i have an external 2tb ard drive which already has around 1tb of data on it
and i have tried the time machine set up and it says it needs to wipe data...?  is there any way around this
also is it worth partitioning the 2tb drive to 1tb each and have the time machine on one partition and any other files i need to save on the other partition?
i am trying to understanding the saving structure better
ideally i would want to access the 2tb harddrive on a windows machine too? is that possible? so it will have the the time machine backup and other files which i can access via a mac or a windows machine
please help

Make 2 partitions, one for Time Machine, formatted for Mac only (MacOS Extended (Journaled), the other should be formatted as Fat32 or ExFat for use with Macs and Windows. Fat32 is the more reliable choice but ... it has a filesize limit of 4GB, if that will be an issue for you choose ExFat.
Unless you have to I strongly suggest using Fat32 rather than ExFat.
Oh, all data currently on the drive will be erased, so move it somewhere else or back it up before you start.

  • In migration assistant, using a time machine backup, what is the extra data that appears after I deselect all the checkmarks under the user?

    When restoring a time machine backup using Migration Assistant, I'm given a choice of what to restore. If I click on a user, and I deselect everything(Desktop, Music, Movies, Documents, etc.) there is still 40 Gygabites of stuff. What is in the 40 Gygabites?!

    Is the HDD in the 2009 15" MBP dead?  (The original source of your data)  If not, you might want ot take it out and put it in an enclosure.
    You might try spotlight on know files to see if that gives you any clues where your data is located.
    You might down load from the Internet OmniDiskSweeper (free) and open it.  It should show you all of the files you have on your MBP and enable to locate them.

  • Can Time Machine Backup a Disk that has OS 10.4.11 On it?

    I have two startup disks on my computer. One starts up with OS X 10.5.2, and the other starts up with OS X 10.4.11. I also have a third disk that I use as the Time Machine backup disk.
    If I have started up with OS X 10.5.2, can I backup the disk that has OS X 10.4.11 with Time Machine? Does Time Machine create a backup that can restore the OS X 10.4.11 disk, operating system and all?

    I think you guys are right! One key is that I now understand can't restore a Tiger system from Time Machine. Thanks. I totally missed that.
    My 10.4.11 "Tiger" system is on my MacBook internal drive, and my Leopard system is on an external drive. What I am going to do is:
    Use Time Machine to back up "Leopard", but not "Tiger"
    I'm going to back up "Tiger" using Retrospect. Then use Restore in Disk Utilities to make a copy of the "Tiger" disk on an external firewire drive. I believe that this disk can be a startup disk, if I so choose.
    Next move the "Leopard" disk to the Mac Book internal drive. I can use either "Restore" or "Time Machine" to do this. I think "Restore" is the way to go, because I won't have to insert the "Leopard" install disk.
    When I am finished, I will have "Leopard" on the MacBook, an external drive, and Time Machine. My old Leopard disk will be archived by Retrospect, and will also reside on a bootable firewire disk.
    Whew!
    What do you guys think about this?
    Thanks for the help, and I think there is a possibility of screwing up when you have two operating systems on two different drives on the same computer. I especially follow your logic on Time Machine being designed for Leopard and not Tiger. Thanks for the clear thinking.
    Long term I am going to have to devise a better method of safely upgrading operating systems while at the same time keep my old stuff available. Time Machine seems to be the perfect solution for that delima.

  • How to restore time machine backup without disturbing already installed app

    Hi!
    My school recently reconfigured/reformatted my macbook and install the school image. Now it is filled with applications that the school help us installed. Now how do i restore the backup that my time machine backups last time? Migration assistant or what? I did not change my mac, it is just that my hard disk got reconfigured. How do i restore backup without disturbing the apps my school installs?
    Please help thanks!

    I'm not sure what you mean by that. Is your user account still there?
    If not, and if you have either Time Machine backups or a "clone" as backups, yes, use Migration Assistant. See [Using Migration Assistant|http://web.me.com/pondini/AppleTips/Migrate.html]. Note that you must be logged-on with a user account that's named differently from any of the accounts you want to transfer, or else be prepared to rename the duplicate.
    If your backups aren't either Time Machine backups or a "clone," you'll have to drag and drop or restore using the app that made them.

  • Time Machine backup for old computer has been named for new computer

    On my new Time Capsule, I backed up the entire disk from my older computer. While consulting with a live help technician for an unrelated problem, he had me reset the Time Capsule using the newer computer. To resume use of the Time Machine backup from my older computer, I had to gain permission . . . and subsequently discovered the reason why. Reseting with the new computer caused the backup volume to be renamed with the new computer's name.
    Sooo, 1) how do I correct the naming error, and 2) will further confusion occur when I then go to back up the new computer?

    It may or may not ask you to reformat the disk when you set it up as the backup for that new computer. If it does, I think you can cancel it.
    What I would do is open Migration Assistant, then import your applications/documents/etc. onto the new computer, and then use the Time Machine disk for backup (formatting it if it asks you to).
    You'll at least have recent files and stuff like that, which may not be as good as an incremental history but at least it's something.

  • Does Time Machine backup both of my accounts data?

    I have 2 accounts in my mac.. For the purpose of this dis ill call em acc1 and acc2. I recently backedup using an external HDD with time machine using acc1 and was wondering if the data backed up was only from acc1 or did the backup backedup both datas in acc1  and 2?

    It will back up both:

  • Can include in time machine backup the content of an firewire hard disk attached to my mac? How? Thanks from spain!

    Apologyze my english.
    I hace a firewire disk attached to my mac with my iphoto files.
    How can I include this files into the time machine copy in my time capsule?
    Thanks from spain!

    If it's connected and turned on, and it's not in Time Machine's Exclude list, then it will be backed up. Normally, external drives are automatically excluded. To back them up you need to remove them from the Exclude list.

  • Mac os x mountain lion The volume is already used for Time Machine backups

    Hey
    I downloaded the Mac OS X Mountain Lion and then I clicked on the hard disk and then was "The volume is already used for Time Machine backups.
    Can you help me please

    Well, this isn't a download window, it's an installer window. You need to select one of your hard drive volumes on which to install Lion.
    Your computer's main drive apparently has been used by you for TM backups which is a first class "no no." See: OS X v10.6, OS X Lion- Cannot install Mac OS X v10.6 or later on a volume used by Time Machine for backups.

  • Clean install selective restore from time machine backup

    Hi,
    My harddisk crashed, and I have just installed a new harddrive.
    I have just installed a fresh OS and am wondering if it is possible to selective restore stuff from my time machine backup.
    I only want to restore some of my data file.
    When I plugin my time machine backup. the preference pane does recognize that i have previous backup. But when I go into time machine state, the older stuff doesn't show up.
    how can i get my old files back?
    I can't see anything from before I changed my harddisk and did a few reinstall of the OS.

    Restoring specific files or folders
    While your backup disk is connected, click the Time Machine icon in the Dock and the Time Machine restore interface appears. You can literally see your windows as they appeared "back in time." Note: If you use FileVault, you cannot browse for individual items in your Home folder. However, you can restore all files and folders by using the Restore System from Backup feature of the Mac OS X Installer.
    You can use the timeline on the right side of the window to reach a certain point back in time (the timeline shows the times of all backups on your backup disk). If you don’t know exactly when you deleted or changed a file, you can use the back arrow to let Time Machine automatically travel through time to show you when that folder last changed.
    You can also perform a Spotlight search in the Time Machine Finder Window search field to find a file. Simply type the Spotlight search field and use the back arrow to have Time Machine search through your backups to find what you are looking for.
    Before you restore a file, you can also use Quick Look to preview a file to make sure its the one you want. Highlight the file and press the Space Bar to bring up a preview.
    To restore, select the file/folder and click the "Restore" button. The file will automatically be copied to the desktop or appropriate folder.  If the file you are restoring has another file in the same location with the same name, you will be prompted to choose which file to keep or keep both.
    Restoring your entire system from a backup
    If you are restoring a backup made by a Mac to the same Mac
    With your backup disk connected, start up your Mac from your Mac OS X v10.5 or Mac OS X v10.6 installation disc. After starting up, use the Restore System from Backup feature of the Mac OS X Installer.
    Note: If "You can't restore this backup because it was created by a different model of Mac" appears when restoring a backup that was made on a different Mac, follow the onscreen instructions.
    If you are restoring a backup made by one Mac to a completely different Mac
    Important: If the backup you are about to restore is from a completely different Mac, use the Migration Assistantto transfer data from the backup, as described in the next section.
    Restoring a Time Machine backup on a new Mac
    When you buy a new Mac, you can transfer all of your applications, files, settings, and other information from a Time Machine backup you've already made.
    You will be asked if you want to transfer files when you start up your new Mac for the first time. Or, you can use the Migration Assistant (located in Applications/Utilities).
    If you use a Time Capsule, see Restoring files from a Time Capsule backup.
    Deleting data from a Time Machine backup
    To delete all backups of one or more items from a Time Machine backup, follow these steps:
    Click the Time Machine icon on your Dock to enter the Time Machine restore interface.
    Click on the item you would like to delete. Command-click to select multiple items.
    Control-click (or right click) the highlighted item(s) and select "Delete All Backups of..." from the contextual menu, or select "Delete all backups of..." from the Action Item menu.
    Authenticate with an administrator password when prompted.
    Important:  Do not use the Finder to move to the items to the Trash, or to move or delete items in your Time Machine backup repository. The folder containing your Time Machine backup repository is called "Backups.backupd" and is located on the external disk or Time Capsule you have chosen in Time Machine preferences.

  • Concerns ALL Time Machine Users. HOW TO MOVE Time Machine backups. Help !

    Concerns ALL Time Machine Users :
    MOVE (or COPY) Time Machine backups from a "x"To Disk to an "y"To greater disk.
    Hello and thank you all for reading me,
    First, excuse me if I make language errors (I'm French).
    Secundo, I don't know if you'll find something interesting for you
    in what I write about Time Machine and my own problems,
    but there's a possibility also that YOU could perhaps help me.
    I'm talking about Time Machine and his **** Backups.backupdb folder,
    containing "*Name of your Mac*" folder,
    this folder containing Time Machine backups, format : YYYY-MM-DD-HHMMSS
    Time Machine doesn't recognize the backups it made *IF YOU MOVE THEM*.
    I have perhaps a solution in this message.
    You'll see below what kind of problem I (and you could) have.
    Since 12/01/10, an Apple Adviser Level Two (and me)
    are trying to understand how to move backups from TM1To Disk to, let's say, a bigger one.
    My case is TM1,5To.
    *Purpose :* Move 19 backups from Time Machine X disk to Time Machine Y disk.
    Delete TMX disk Time Machine backups after that.
    Make TMY disk the current used Time Machine Disk.
    I don't remember exactly what we did before
    (we even created a "root" account with password (dangerous to do),
    but it didn't solve the problem),
    but we finally copied :
    TM1To > Backups.backupdb > *MacBook Pro* folder (containing 19 backups) into :
    TM1,5To > Backups.backupdb folder.
    The Copy application announced *16 hours !* (without antivirus, to remove absolutely).
    So I said goodbye and thank you to my Apple Adviser. After *8 hours*, Copy failed.
    BUT it had succeeded to copy *4 backups ONLY* (why ?) in TM1,5To.
    I immediately verified and checked each of these with Get Info.
    They had EXACTLY the same size (Byte to Byte) as in TM1To.
    ➔ BUT HERE IS MY OBSERVATION :
    After designing TM1,5To as Time Machine Disk, I ordered it to Backup (now).
    And what did Time Machine do in TM1,5To > Backups.backupdb ?
    It created a *NEW folder*, named *MacBook Pro 2* !
    ➔ *I HAVE NO ACCESS* to TM1,5To > Backups.backupdb > *MacBook Pro* (4 backups copied from TM1To, remember) ;
    ➔ while I still *HAVE ACCESS* to TM1To > Backups.backupdb > *MacBook Pro* (19 backups) ;
    ➔ *AND I HAVE ACCESS* to TM1,5To > Backups.backupdb > *MacBook Pro 2*,
    where Time Machine makes actually his backups.
    *NOTE :* If you *change the name* of your computer,
    Time Machine *changes automatically the name* of the folder who is in Backups.backupdb folder.
    ➔ ① I have *never seen* such protections (Sharing and Permissions).
    You are not allowed to do anything. I've tried to change permissions,
    first : "R+W", after that : "Make (Me) the owner", I can tell you : DON'T DO IT !
    ➔ ② It's impossible to install an OS on a Time Machine disk
    (I thought it would allow better permissions).
    OS Installer detects the existence of a Backups.backupdb folder
    and refuses to install on this disk or partition.
    I have now the bad intent to install minimal OS X
    1) after deleting (how ?) this folder (but not its contents, how to move it ?)
    and 2) declare *after that* the disk as Time Machine disk.
    ➔ ③ Time Machine doesn't backup OTHER Time Machine backups
    (who are in an ancient-not-choosed-for-backups Time Machine disk) NOR backups this disk
    (detects, once again, the existence of a Backups.backupdb folder).
    AND you can't *absolutely not remove backups from the folder the're in*
    (for me, *MacBook Pro* or *MacBook Pro 2*).
    ➔ ④ I didn't have time to do it, but I think there would perhaps be a solution
    in restoring backups in partitions specially created to receive them (having the same name,
    that sort of thing) and then re-backup these partitions (vicious and complicated).
    There is a function on Mac OS X Install DVD : start with it, and then (do not install)
    choose "*restore from Time Machine backup*" from the menu bar (it's called "Utilities", I believe).
    ➔ ⑤ I *absolutely don't understand* what follows :
    — If I add (in my TM1To disk) the bytes of the 19 backups
    in Backups.backupdb > *MacBook Pro* folder, I obtain about *1,8 To*.
    — It's impossible (and not french).
    — When I check the size used with Disk Utility (NOT with Get Info),
    I find a correct (?) size : *about 750 Go*.
    — What are Time Machine backups made of ?
    It can't be aliases (because of their size, and because *aliases suppose originals,
    and where could they be ?*), or am I wrong and becoming crazy ?
    ➔ ⑥ If you refer to the numbers shown at the end of this text (*4 backups*),
    you'll see I could *delete duplicate elements* inside these 4 backups,
    to win space (but *what kind* of space *if I delete aliases* ?).
    Back-In-Time (see below) says he does it.
    BUT is it really the OLDEST items I have to destroy (see ⑤),
    when I don't know with what kind of ARTEFACT I'm acting ?
    What does Time Machine delete to create more backup space ?
    Is it REALLY the OLDEST backups it treats, or duplicates, OR ?
    *What you can do :*
    Find and go to Tri-Edre.fr or Tri-Edre.com/fr site (it's a french company
    that creates small Mac applications since fifteen years at least,
    I think I already bought them several programs in 1990) ;
    Their program *Back-In-Time 1.4.4* is free (Trial) and complete to download (with PDF docs too).
    It is *ENTIRELY DEDICATED* to Time Machine and *things you can't do* with.
    Price is about 30 €, I think it's worth.
    The TRIAL version you will obtain can only work on the LAST Time Machine backup,
    but you will see what's featured *AND :*
    You will ACCESS to ANY Time Machine backup you want
    (It has to be the last of a serie of backups, but the serie you want.
    I've bought the application and own an activation key, but you understand I can't give it to you
    (it would not be ethic) and anyway you would be obliged to disconnect AirPort, Ethernet etc.
    •➔ I have bought the application because I thought (it's said in PDF FAQs) I could IN THE END move Time Machine backup files, but it cannot, (I'm afraid).
    *BUT ANY ACCESS PROBLEM IS SOLVED.*
    •➔ Back-In-Time 1.4.4 can *delete :* duplicate backups, complete backups,
    or duplicate items inside one or several Time Machine backups,
    things that I believe impossible with Time Machine itself
    (I've seen it offers to delete ALL occurences of an item) ;
    •➔ The application can also restore anything you want, where you want
    (but I think Time Machine does it too ?)
    •➔ Believe it or not, but since I've bought it on 15/01,
    I've only worked about 2 hours (no, much more) on it
    and didn't make sufficient progresses (enhancements ?)
    to talk of it with sufficient experience (I'm a bad guy, don't you think ?)
    •➔ Tri-Edre offers on-line support, e-mail support (and so on),
    and I EVEN didn't manage to join them, because I did many other things,
    and also somewhat have been disgusted *not to be able to move* or copy
    *(accessible by Time Machine after that)* backups,
    and I also didn't succeed (*another Time Machine inconvenient*) to DESTROY an ".inProgress"
    Time Machine (package) which doesn't work anymore (several interruptions while active),
    date (and name) 2010-01-27-164345.inProgress, but is used (*with failure results*)
    by Time Machine (it's turned off till I find how to destroy its **** ".inProgress" package.
    •➔ I've asked my Apple Adviser Level 2 to wait for news from me
    before working himself on the problem, and I think I will send him this message
    to prove I haven't forgotten him.
    •➔ I'll send it to Tri-Edre too, in the same move.
    I hope those remarks to be useful for somebody, tell me if it has helped.
    I will also publish this in any Time Machine topics I find here, and in MacRumors site too.
    As you can see, I need help too … Does anybody have an idea ?
    Perhaps if I used a specific Copy software, it could work ?
    You'll see below an example of some time I've spent to study my problem
    (you will think I'm crazy).
    With my kind regards, and good luck if you have other Time Machine problems !

    Dear James Pond,
    Thank you once again, and, don't be afraid, I will be as short as possible,
    but I need to use your last reply (I've cut all what was already said).
    JP ➔ You can copy an entire set of backups, but you cannot copy part of it successfully. See #18 etc.
    JP ➔ Read this from the first paragraph: "you cannot copy only selected backups,
    or merge two (or more) sets of backups." The structure of the backups simply will not allow it.
    I've read it, and found it regrettable. And I've also read, after that, what were the solutions under Leopard and Snow Leopard, and my conclusion is that it's a *dead end* for me. In short,
    — I can't move (by drag and drop) the 1To's Backups.backupdb folder (containing MacBook Pro, 19 backups, access) to 1,5To, because there exists already the Backups.backupdb folder created by copy on 12/01 with Apple Assistance (containing [MacBook Pro, 4 backups of 19, no access] and [MacBook Pro 2, 15 backups, access]). I don't even know if it could be deleted by the copy (and I don't wanna do that anyway) ;
    — I can't rename (and what for, I already forgot it) any Backups.backupdb folder nor delete it ;
    — I can't copy any Computer'sName folder (entire set containing backups), being in a Backups.backup.db folder, into another Backups.backupdb folder ;
    — I can't copy any (or all of an entire set) YYYY-MM-DD-HHMMSS backup(s), being in a Computer'sName folder, into another Computer'sName folder (even if it would be empty).
    — Saying NONE in Time Machine Preferences and putting it to OFF is simply no use.
    All is said. What I can try to do is :
    — Delete (not with Finder, but with Back-In-Time) all duplicate things I find in all backups and also entire duplicate backups (I have full access to all with the software) ;
    — Restore each of the reduced-to-minimum backups obtained in specially right-sized partitions wearing the YYYY-MM-DD-HHMMSS name of each restored backup. Time Machine doesn't backup his backups, but will backup these partitions.
    I'm afraid to be actually completely running out of the target, when I read what I write … It's time to go to bed !
    Reminder (OH) : Where did you find these amazing informations ?
    JP➔ Some of it is detailed here: http://www.appleinsider.com/articles/07/10/12/roadto_maco[]sx_leopard_timemachine.html
    ➤ Thank you ;
    JP➔ and here:
    http://arstechnica.com/apple/reviews/2007/10/mac-os-x-10-5.ars/14
    ➤ Thank you too ;
    JP➔ You have to understand the structure. When TM does the first backup, yes, it copies everything.
    On subsequent backups, it copies what's new or changed, but also makes "hard links" (sort of like aliases) to the copies of the things that didn't change. That's how it can only back up a few things each time, but show you a complete "snapshot" of the way your entire system looked at the time of every backup.
    ➤ I'll do my best to understand.
    JP➔ Time Machine deletes backups under two conditions. See the first part of #12 in the Frequently Asked Questions User Tip, also at the top of this forum.
    Under normal circumstances, you should not have to delete any backups. See the rest of #12.
    ➤ I understood why Time Machine didn't delete oldest backups : they were not weeklies ones.
    Reminder (OH) : How can I destroy the (corrupted ?) not working "2010-01-27-164345.inProgress" in 1,5 To, which causes Time Machine to abort any backup of any size I ask ?
    JP➔ Why do you think it's corrupted? TM is designed to "recover" a partial backup.
    ➤ I'll verify that with the little Tools/Apps I discovered in your FAQ User Tip document and downloaded immediately.
    Why didn't Apple tell me anything ? It's my fault, I'm perhaps not clear and not demanding enough more from them.
    JP➔ You cannot install OSX on a disk containing TM backups. That's because they need to be on separate disks.
    Technically, you could put them on separate partitions of the same disk, but that would not be a good idea.
    ➤ I never told you that (there would be no interest at all). I talked about the same location, to see if it would allow me more permissions, but if all works without doing it, it's really no use.
    JP➔ Sorry, I don't know what that means.
    ➤ I'm sorry, I didn't explain : "but if all works" meant : Copy Backups.backupdb, "without doing it" meant : Install OSX.
    ➤ If I install an OSX BEFORE, Time Machine will REFUSE completely to backup on it, it's understood.
    JP➔ Correct. The partition you're running from will not be an option in TM Preferences > Select Disk. That prevents TM from backing-up it's own backups!
    ➤ Would it be so absurd ? Maybe it could resolve my actual problem ?
    I think you are right, but I don't know why. I trust you.
    Reminder (OH) : "I will not bore you again except if I don't find a specific answer to an unknown-never-seen-incredible malfuction."
    JP➔ Don't worry about that -- thats what this forum is for, especially if you're still having problems.
    ➤ It's seems in fact that there is no possible solution, except what I said above and is certainly crazy/out of subject.
    Just try to be as clear and concise as you can.
    And please don't post the same things repeatedly -- it wastes your time and ours, and can confuse other folks.
    ➤ You're absolutely right and I tried to do so this time, and I'm sorry because I see it's still (far) not enough (short).
    Thank you once more. I wish you a good evening and week-end. Here it's 01:40 AM.
    With my kind regards

  • Time Machine Backup EXTREMELY SLOW

    I've recently noticed that my Time Machine backups from my Mid 2009 iMac 3.06 to a WD 1tb MYBook take an incredibly long time.  For example, an hourly backup where nothing has really changed (350k according to a TM log) takes over 30 minutes.  I've been working with applecare and they can't pin it down.  I've tried the following and nothing has changed-
    - creating a back to a brand new drive
    - disabling or deleting every startup program and launch agent
    - Created another new user and backed up from there
    - Reinstalled OSX to repair Time Machine
    - Created a new boot partition on my HD and installed OSX
    - I used the same backup disc on my laptop and it worked fine
    The strange thing is hat everything seems to work fine.  I ran a verify on my disks.  I Boot my original OS disc in and ran the hardware test.  NOthing finds a problem.  I tried writing large files to and from my HD to see if that could be the problem.  MY HD reads and writes quickly (2.5gb copies to/from an external drive in less than 2 minutes).
    The only thing that has changed in the past 6 month s is that I updated my ram from 4 to 8GB with Kingston ram.  Could it be a bad piece of RAM or my logic board?  Everything else seems to be working fine.
    Anybody experience anything likes this???

    Hey - apologize if this has been covered, but despite much searching, I haven't found a solution to my problem...
    After a hard drive crash, I restored using a Time Machine backup. I figured it would be a good idea to start a fresh Time Machine backup going forward.
    Does that mean you erased or reformatted the drive?
    If you deleted some or all of the backups via the Finder, cancel the backup, reformat the drive, and start over.
    Using a LaCie 500GB Firewire 800 drive (formatted MacOS Extended Journaled), after one hour, only 5GB has been backed up. As my MacBook Pro has 165GB of data, at this rate, it will take almost two days.
    Does that hour include the "Preparing" phase? If so, nothing at all was backed-up during that time, so the actual rate is probably much faster.
    Also note that the first items backed-up contain a very large number of mostly small files; there are things that must be done for each item, so that sort of backup will be longer than saving a few large files that total the same amount of space. The speed of the backup will increase and decrease during the backup; initial estimates are almost always quite high.
    I've removed the Time Machine drive from Spotlight indexing. I have ensured Norton AntiVirus is not running. What else can I do to speed this up? It seems extremely slow by all comparisons I've read.
    First, be sure the *Partition Map Scheme* of the LaCie is correct. Use the procedure in item #C1 of the Time Machine - Troubleshooting *User Tip* at the top of this forum.
    Also see item #D2 of the same post (you've already done the first two things). Don't try the +*Repair Disk+* while the backup is running, or if you erased or reformatted it before starting this backup.

  • Time machine backup problem with new MacPro

    On my new MacPro (6 core, 32gb, 1TB ssd) I am trying to do my initial Time Machine backup. The MacPro has 350 GB of files on it. When I start Time Machine it shows that it is backing up 355 GB of data onto the 4 TB LaCie drive and the time to complete is about 20 minutes. (The extrnal HD is excluded from the backup list). When it nears the end of the 355 gb backup all of a sudden it just starts increasing both the number of gbs copying and number of gbs left to copy (both numbers just start going up incrementally together) way beyond the initial 355 gbs - I've stopped it at 910 GBs several times. Tried different external hard drives, restarts etc.
    Any ideas what is going on?
    Thanks

  • HT201250 Can I partition my external hard drive and use one partion for time machine and the other one for data that i may want to use in different computers?

    I have this doubt. I've just bought an external drive, especifically a Seagate GoFlex Desk 3 tb.
    I want to know if it is recomendable to make a partion exclusively for time machine and let another one so I can put there music, photos, videos, etc that I should need to use or copy to another computer.
    May half and half, 1.5 tb for time machine and 1.5 tb for data.
    I have an internal hard drive of 500 GB (499.25 GB) in my macbook pro.
    Any recommendation?

    As I said, yes. Be sure your Time Machine partition has at least 1 TB for backups.
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to two (2). Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
