Can time machine backup internal hard drive and external hard drive?

Hi, I have an iMac that I recently bought Leopard for specifically for Time Machine, which I heard rave reviews. I have a 160gb internal drive that I use for the OS and a 750gb external drive that I use for storing all my media (pics, music, movies). I recently bought an additional external hard drive, capacity 1tb. The original intention was to backup both my internal drive and my external drive to the new 1 tb drive through time machine.
When I go into the Time Machine preferences/options, it lists that the 750 drive is not to be backed up and I cannot remove it from the list. I called Apple support and they stated that you cannot backup an external drive through Time Machine which I think is ridiculous.
Both drives are connected to the computer via Firewire. Is there something I'm not doing right? Does anyone have a possible solution?
Please help as I incredibly annoyed with Apple if this is actually the case. Thanks

they told you that?! unbelievable. that's quite false. TM will back up any directly attached drive (external or internal) provided it's properly formatted. it has to be formatted mac os extended. how is your drive formatted?
which I think is ridiculous.

  • Has anyone enabled time machine using a linksys router and external hard drive? And if so how?

    Has anyone enabled time machine using a link sys router and external hard drive? And if so how?  I have a Linksys E4200 wireless router with a usb port on it.  I also have a Western Digital Elements 1TB external hard drive.  I would like to be able to use this hard drive with time machine.  Has anyone done so and if so how can I do so?

    You might get some responses, but we don't see many Linksys users on an Apple forum so it may be awhile before you see an answer.
    It might be useful to point out that Apple does not even support Time Machine backups to the USB port on their own AirPort Extreme wireless router, so we may be heading down a very slippery slope here.
    I've tried Time Machine backups on an AirPort Extreme router a number of times in the past. It's just not reliable. Works for awhile, then has corruption problems. Or has corruption issues immediately. I once went a month or so and thought I had it nailed, then got smacked with a corrupted set of backups again.
    But, I guess you never know. It might work on the Linksys. If you decide to try this, I would suggest that you have another backup plan in place for your important data.
    Hope that some Linksys users will respond so we can all learn.

    Hello Drake, I suspect one or more of the Drives needs repairing, but...
    Have you looked through Pondini's extensive TM help site?

    Can't imaging something not being covered there.

  • I have a mid2009 MacBook Pro for which I have been using a USB WD HD for Time Machine.  I'd like to get a wireless HD  and start a new Time Machine backup for this Mac and retire the 5  year old WD drive.  Can I start over?

    no archive/ backup is perfect, HD clones can be set to make incremental additions, same as time machine however, though they are more time involved in doing so.
    See the + and - of all data backup/ archives below and "spread it around".... or the "dont put your eggs all in one basket" philosophy.

    Data Storage Platforms; their Drawbacks & Advantages
    #1. Time Machine / Time Capsule
    Drawbacks:
    1. Time Machine is not bootable, if your internal drive fails, you cannot access files or boot from TM directly from the dead computer.
    2. Time machine is controlled by complex software, and while you can delve into the TM backup database for specific file(s) extraction, this is not ideal or desirable.
    3. Time machine can and does have the potential for many error codes in which data corruption can occur and your important backup files may not be saved correctly, at all, or even damaged. This extra link of failure in placing software between your data and its recovery is a point of risk and failure. A HD clone is not subject to these errors.
    4. Time machine mirrors your internal HD, in which cases of data corruption, this corruption can immediately spread to the backup as the two are linked. TM is perpetually connected (or often) to your computer, and corruption spread to corruption, without isolation, which TM lacks (usually), migrating errors or corruption is either automatic or extremely easy to unwittingly do.
    5. Time Machine does not keep endless copies of changed or deleted data, and you are often not notified when it deletes them; likewise you may accidently delete files off your computer and this accident is mirrored on TM.
    6. Restoring from TM is quite time intensive.
    7. TM is a backup and not a data archive, and therefore by definition a low-level security of vital/important data.
    8. TM working premise is a “black box” backup of OS, APPS, settings, and vital data that nearly 100% of users never verify until an emergency hits or their computers internal SSD or HD that is corrupt or dead and this is an extremely bad working premise on vital data.
    9. Given that data created and stored is growing exponentially, the fact that TM operates as a “store-it-all” backup nexus makes TM inherently incapable to easily backup massive amounts of data, nor is doing so a good idea.
    10. TM working premise is a backup of a users system and active working data, and NOT massive amounts of static data, yet most users never take this into consideration, making TM a high-risk locus of data “bloat”.
    11. In the case of Time Capsule, wifi data storage is a less than ideal premise given possible wireless data corruption.
    12. TM like all HD-based data is subject to ferromagnetic and mechanical failure.
    13. *Level-1 security of your vital data.
    Advantages:
    1. TM is very easy to use either in automatic mode or in 1-click backups.
    2. TM is a perfect novice level simplex backup single-layer security save against internal HD failure or corruption.
    3. TM can easily provide a seamless no-gap policy of active data that is often not easily capable in HD clones or HD archives (only if the user is lazy is making data saves).
    #2. HD archives
    Drawbacks:
    1. Like all HD-based data is subject to ferromagnetic and mechanical failure.
    2. Unless the user ritually copies working active data to HD external archives, then there is a time-gap of potential missing data; as such users must be proactive in archiving data that is being worked on or recently saved or created.
    Advantages:
    1. Fills the gap left in a week or 2-week-old HD clone, as an example.
    2. Simplex no-software data storage that is isolated and autonomous from the computer (in most cases).
    3. HD archives are the best idealized storage source for storing huge and multi-terabytes of data.
    4. Best-idealized 1st platform redundancy for data protection.
    5. *Perfect primary tier and level-2 security of your vital data.
    #3. HD clones (see below for full advantages / drawbacks)
    Drawbacks:
    1. HD clones can be incrementally updated to hourly or daily, however this is time consuming and HD clones are, often, a week or more old, in which case data between today and the most fresh HD clone can and would be lost (however this gap is filled by use of HD archives listed above or by a TM backup).
    2. Like all HD-based data is subject to ferromagnetic and mechanical failure.
    Advantages:
    1. HD clones are the best, quickest way to get back to 100% full operation in mere seconds.
    2. Once a HD clone is created, the creation software (Carbon Copy Cloner or SuperDuper) is no longer needed whatsoever, and unlike TM, which requires complex software for its operational transference of data, a HD clone is its own bootable entity.
    3. HD clones are unconnected and isolated from recent corruption.
    4. HD clones allow a “portable copy” of your computer that you can likewise connect to another same Mac and have all your APPS and data at hand, which is extremely useful.
    5. Rather than, as many users do, thinking of a HD clone as a “complimentary backup” to the use of TM, a HD clone is superior to TM both in ease of returning to 100% quickly, and its autonomous nature; while each has its place, TM can and does fill the gap in, say, a 2 week old clone. As an analogy, the HD clone itself is the brick wall of protection, whereas TM can be thought of as the mortar, which will fill any cracks in data on a week, 2-week, or 1-month old HD clone.
    6. Best-idealized 2nd platform redundancy for data protection, and 1st level for system restore of your computers internal HD. (Time machine being 2nd level for system restore of the computer’s internal HD).
    7. *Level-2 security of your vital data.
    HD cloning software options:
    1. SuperDuper HD cloning software APP (free)
    2. Carbon Copy Cloner APP (will copy the recovery partition as well)
    3. Disk utility HD bootable clone.
    #4. Online archives
    Drawbacks:
    1. Subject to server failure or due to non-payment of your hosting account, it can be suspended.
    2. Subject, due to lack of security on your part, to being attacked and hacked/erased.
    Advantages:
    1. In case of house fire, etc. your data is safe.
    2. In travels, and propagating files to friends and likewise, a mere link by email is all that is needed and no large media needs to be sent across the net.
    3. Online archives are the perfect and best-idealized 3rd platform redundancy for data protection.
    4. Supremely useful in data isolation from backups and local archives in being online and offsite for long-distance security in isolation.
    5. *Level-1.5 security of your vital data.
    #5. DVD professional archival media
    Drawbacks:
    1. DVD single-layer disks are limited to 4.7Gigabytes of data.
    2. DVD media are, given rough handling, prone to scratches and light-degradation if not stored correctly.
    Advantages:
    1. Archival DVD professional blank media is rated for in excess of 100+ years.
    2. DVD is not subject to mechanical breakdown.
    3. DVD archival media is not subject to ferromagnetic degradation.
    4. DVD archival media correctly sleeved and stored is currently a supreme storage method of archiving vital data.
    5. DVD media is once written and therefore free of data corruption if the write is correct.
    6. DVD media is the perfect ideal for “freezing” and isolating old copies of data for reference in case newer generations of data become corrupted and an older copy is needed to revert to.
    7. Best-idealized 4th platform redundancy for data protection.
    8. *Level-3 (highest) security of your vital data. 
    [*Level-4 data security under development as once-written metallic plates and synthetic sapphire and likewise ultra-long-term data storage]
    #6. Cloud based storage
    Drawbacks:
    1. Cloud storage can only be quasi-possessed.
    2. No genuine true security and privacy of data.
    3. Should never be considered for vital data storage or especially long-term.
    4. *Level-0 security of your vital data. 
    Advantages:
    1. Quick, easy and cheap storage location for simplex files for transfer to keep on hand and yet off the computer.
    2. Easy source for small-file data sharing.

  • HT201250 Can Time Machine backup files stored on external hard drive

    Can Time Machine back up files that are stored on external hard drive and save them on a different external hard drive?
    I have my pictures stored on an external hard drive connected to my iMac. I want to make an exact copy of the pictures folder on a separate external hard drive. Can Time Machine do that?
    If yes, how?
    If no, what's a good way to create a mirror of the folder on External Hard Drive #1 (the original) on External Hard Drive #2 (the backup)?
    I am not opposed to manually copying every couple weeks or month, but (1) it's less convenient and (2) I got an error message the first time I tried this saying the files couldn't be copied because some of the files being copied had the same name as each other (not exactly that, I'm at work and don't have the message in front of me right now, but that was the gist of it).
    Thanks!

    1. Yes, if both drives are formatted as Mac OS Extended (Journaled).
    2. Reformat the drives if needed, open the Time Machine pane of System Preferences, and remove the drive with the pictures from the list of items set to be excluded.

    I upgraded to Maverick and now Time Machine will not connect to the external hard drive to back up files.  The external hard drive is a Western Digital "My Book Live" 2 TB.  How do I solve problem?

    I also had problem accessing my WD MyBookLive after upgrading to Maverick.
    To resolve the problem, I used  Connect To Server (Cmd K) to specify the IP address.
    Then I enter a user id and password I created in the MyBookLive.
    You can also verify that you have admin access to the MyBookLive using Safari or Chrome.
    Just enter the MyBookLive IP address as the URL.

  • If I deleted a file on my Mac would Time Machine delete its copy on my external hard drive when backing up?

    I just finished backing everything up onto my new 2T WD My Book Essential because my Macbook Pro is absolutely full of Photoshop files. I want to delete them from my Mac (since they're backed up) but I'm too scared Time Machine will delete them from my external hard drive.
    Thanks in advance.

    Move the images over to an external drive that is connected to your Mac by USB or FireWire.
    Then....Time Machine will backup both your Mac..and..the hard drive automatically. 
    Can you elaborate on this?
    I have a 128GB McAir (mid 2011 model) with a 2GB TC for backup. I need another external hard drive to save pictures and home HD videos. I wanted to partition the TC but learned that is not recommended. So now I’m looking to get two external hard drives to store priceless files and back it up.
    Your comment makes me think I only need one external hard drive and use the 2GB TC as backup. A good option since 2GB is an overkill for a 128GB notebook.
    Can you please share the steps? Plug in a HDD to McAir and run Time Machine? Is that it?
    Thanks.

  • Can Time Machine backup Windows 2003 servers?

    Hi,
    Before anybody casts any stones, I'm Pro mac. I'm currently working at a company that only has Windows 2003 servers. We need a new DR & Backup system for our Windows servers. Can time machine backup and restore to Microsoft Windows 2003 servers?
    Anybody have an experience on this topic?
    Thanks,
    Chris.

    Time Machine can not back up remote drives of any kind. also, in can only back up directly attached drives if they are formatted mac os extended. that excludes any windows drives in any shape or form.
    you should consider a different backup solution. You can try CCCloner. It might be able to backup a windows server.

  • Time Machine backup restores OS X and Apps

    Time Machine backup restores OS X and Apps or only Data?

    Hi lseit,
    Welcome to the Apple Support Communities!
    I understand that you would like information what what information is restored while restoring from Time Machine. For information on this process, please review the information in the attached article. 
    Mac Basics: Time Machine backs up your Mac - Apple Support
    Restoring data from Time Machine backups
    With Time Machine, you can go "back in time" to restore files, versions of files, or your entire system. If Time Machine alerts you that your Time Machine backup disk can't be found, make sure your backup drive is connected and mounted.
    Best regards,

  • Can Time machine backup an aperture datatbase ?

    Hi to all of you,
    I am new to Mac and new to aperture 3.
    Can Time machine backup an aperture datatbase ?
    I have set up time machine to back up my mac an though I was out of trouble until I heard someone saying this is not the case.
    So can TM backup the database ? When is it open?
    If not what else can I do ?

    Inside the Aperture Library, there are a few large databases that are marked as changed anytime you do many common things inside Aperture. Even a very small change can cause several of these large files to be backed up, and it will consume a fair bit of space.
    One of the big changes under the hood in Aperture 3 is that the main database file has been split into several smaller ones, but more importantly the thumbnail file that existed for each Project and was changed each time any adjustments were applied in that Project has been split into a number of smaller files.
    Using TM to backup the Library is still going to use space relatively fast, but not as fast as it did with Aperture 1 & 2.

  • Hard Drive and External Hard drive filled up instantly?

    While using my Mac today, I came up with a dialogue box saying my hard drive (and external hard drive) are both full. This is strange because this morning I had over 30GB on my internal hard drive, and between 100GB and 300GB on my external hard drive.
    How can both of these fill up at once?
    I had uploaded approximately 100 photos to my external hard drive this morning, but there was still plenty room then.
    What is going on?

    HI Matt,
    Get Disk Inventory so you can see exact sizes of files and folders.
    *"I came up with a dialogue box saying my hard drive (and external hard drive) are both full. This is strange because this morning I had over 30GB on my internal hard drive, and between 100GB and 300GB on my external hard drive."*
    Not sure what's going on but it would be a good time to boot from your install disk and check the hard drive.
    Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
    Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
    Select your HDD (manufacturer ID) in the left panel.
    Select First Aid in the Main panel.
    *(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
    Click Repair Disk on the bottom right.
    If DU reports disk does not need repairs quit DU and restart.
    If DU reports errors Repair again and again until DU reports disk is repaired.
    When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
    Select your start up disk and click Restart

    What you need to do is boot into Safe Mode. Then delete the VGA Drivers.
    After that boot normally and install the latest nVidia ForceWare Drivers
