Can Time Machine back up to another internal drive?

Does Time Machine require an external disk for back-up?  I have 4 internal hard drives can I back one to another using Time Machine?  If not is there another user friendly app that will back up to a separate partition or internal HD?

You can use an internal drive. Just select it to be the backup destination in System Preferences Time Machine.

  • Can 'Time Machine' back-up other external hard drives

    Can 'Time Machine' back-up other external hard drives connected to your mac as well as the mac memory itself?

    As Neil says, yes, it can.  But external HDs are excluded by default;  you have to tell Time Machine when you do want to back one up.
    See the exclusions box in Time Machine Prefs > Options.
    If the drive is shown in black, just select it and click the minus sign at the bottom.
    If it's shown in gray, though, it's not formatted for a Mac, and Time Machine can't back it up (and you can't remove it).

  • Can Time Machine back on one external hard drive (work files) to another external hard drive (back up)?

    Can Time Machine on a Mac Book Pro 10.5.8 back up an external hard drive (working files) to another external hard drive (WD dual backup)?

    I have Mountain Lion here ready to upgrade, but I'm scared of what will happen - there's always something when you upgrade, but I guess that's for a different post!
    Yes, it's a different post, but let's make a comment any way.
    Your power pc apps will not work when you upgrade to Mountain Lion. You will have to replace all the apps you use.

  • Can Time Machine back up a failed hard drive, and how long will it take to prepare?

    1. The hard drive in my 2009 MBP has failed. My Time Machine external drive failed about three weeks ago, and I don't know if I'll be able to restore from it. Is it ever possible to backup a failed hard drive with Time Machine? The machine boots, it just comes up beach balls if I use any applications for very long.
    2. I'm trying to back it up right now. I have Time Machine running to a new external drive. It has been stuck on "preparing backup" for about 20 minutes. Everyone says that preparing a first backup takes some time, but no one says if "some time" is 15 minutes or one hour or more. What is a typical length of time for preparing first backup? At what point should I walk away?
    If it's not worth trying to back this drive up myself anymore, I'd love to just drop the thing off and get the hard drive replaced -- but if it's worth doing, I'll take the extra day to back up what I can.

  • Can Time machine back up to two hard drives?

  • Will time machine back up a second "internal" drive?

    I have a Macbook Pro "late 2008" unibody.
    I'd like to eventually buy an SSD drive to use as my "boot up / programs" drive and then use my much larger conventional drive as a "data" drive which will reside where my superdrive was.  Will time machine back up this second drive or is it limited to the drive it's installed on?
    If it's not possible, I'd appreciate any recommendations / tips on how I would back up the second drive or an alternate back up solution to back up both drives more efficiently.

    It'll backup all except items you add in the exclude options as below:

  • Can Time Machine back up an external hard drive plugged into a Time Capsule

    I have iTunes and iPhoto libraries that have outgrown the hard drive on my laptop so I've moved them on to an external hard drive. Since I'd like to move around the house with the laptop, I've plugged the external hard drive in to the Time Capsule so that the files on the external hard drive will be accessible on the network. Now that my really important files live on an external hard drive, I want to back it up.
    Time Machine is backing up my laptop's internal hard drive to the Time Capsule drive, but I can't seem to figure out how to make Time Machine also back up the external hard drive that's plugged in to the Time Capsule.
    Is this possible?

    I understand that [Chronosync|http://www.econtechnologies.com/pages/cs/chrono_overview.html] ($40 U.S.) can do that, but I've never used it.
    If you do that, you'll want to back it up to a disk image on the TC's internal HD, or a separate HD. See #Q3 in [Using Time Machine with a Time Capsule|http://web.me.com/pondini/TimeMachine/TimeCapsule.html] (or use the link in *User Tips* at the top of this forum) for details.

  • Can Time Machine back up a external hard drive connected to Airport Extreme

    I recently purchased a new macbook pro, and airport extreme.
    I attached a 750 GB external hard drive to the macbook pro, and reformatted it so time machine made the initial back up and hourly back ups from there.
    Is it possible to now to unattach the external hard drive and attach it to the airport extreme, where the mac book time machine will back up to the external hard drive through airport extreme?
    i have seen conflicting posts is if this is possible.

    That would probably be safest.
    Note that Apple's position on this got even more negative with Snow Leopard: http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html
    It does work well for some folks, not so well for some, and not at all for others.
    I got a refurb dual-band model in September. It worked well for about 3 months, but lately I get the error 109 and corrupted backups every few days, that Disk Utility can't fix. Once, Disk Warrior could, but since then, if they're corrupted, nothing helps. That's on a year-old Seagate drive that seems fine otherwise, especially when connected directly.
    And I have an excellent wireless connection; it's only about 10 feet from my Mac, speeds are great, S/N ratio is good, etc.
    It makes no sense to me that a TC would work better, but they seem to.

  • Can Time Machine back up Fibre Channel connected drives?

    Hello All,
         I am running Mac OS X 10.7.5. I am trying to back up drives connected to my tower via fibre channel using Time Machine and am getting the exclusion error that others have been reporting on Lion and Mountain Lion. In Time Machine > Options, I select a fibre channel connected drive to include it in the next backup. It disappears from the exclusion list as it should AND the properly "estimated size of full backup" is created. I select "Save." However, when I select "Options" again, the fibre channel connected drive has been RE-EXCLUDED. This happens with all of the drives connected via fibre channel.
         All of the drives have unique UUIDs and display Connection Bus: Fibre Channel Interface and Connection Type: External in Disk Utility. All of the drives are formatted as "Mac OS Extended." The drives are all inside of a Facilis Terrablock 24D and are RAID5.
          Before updating to Lion, we were able to back up these drives via Time Machine successfully for many months.
          Does anyone know if it is possible to back up drives connected via fibre channel with Time Machine on Lion and Mountain Lion? To be perfectly clear, I am trying to simply back up these fibre channel connected drives to a Firewire connected external HD via Time Machine...NOT use a fibre channel connected drive as my Time Machine backup disk.
           Your time and help is greatly appreciated!
    Best,
    LALB

    Others have reported the same issue. Apparently it doesn't work.

  • Can time capsule back up an external hard drive attached to my imac and the iMac internal Harddrive

    Can time capsule back up an external hard drive attached to my imac and the iMac internal Harddrive

    In addition to Kappy's comments, the external drive must be formatted in Mac OS Extended (Journaled) in order for Time Machine to be able to back it up.

  • Can time machine back up on a wireless network

    I would like to find a way to back up my Mac other than on an external drive. Besdides Time Capsule, can Time Machine back up onto other wireless networks? Also, is there a preferred, Mac-friendly online backup available (that may or may not use Time Machine)? I was considering using Carbonite.

    Time Machine can backup to any device that has Time Machine Extensions.. eg some NAS have this.. or another Mac. Maybe some routers with USB drives.. I have heard of Netgear Mac compatible models.. but never forget.. apple change things around with every OS release and these companies will always be playing catchup.
    You may also find it not easy at all to setup Time Machine.. I use a Zyxel NAS single disk model that does support Time Machine.. it has been fine.. but the setup is far more complicated than any TC.
    Very few other devices will have TM available .. but if you use a third party software, then they will generally backup to any shared partition or drive in the network.
    Buy a second hand TC and modify the power supply.. put in a big hard disk.. you can simply plug it into the existing network.. you will find it hard to get anything cheaper that works as well.. and none that will be as easy to setup.
    Fine if you give up on TM.. then whatever external drive the software uses.. no issues.. but TM is designed to only work on HFS+ partition.

  • Can Time Machine back-up to an external ethernet Harddisk?

    Can Time Machine back-up to an external ethernet Harddisk?
    I think it is only possible when the external drive is directly attached via USB or FireWire.
    I do see the ethernet disk in Finder and have access to it via ethernet, but it does not show up in Time Machine.
    What if I connect it to an Airport Extreme ethernet port?
    Time Capsule will work, but only with the internal harddisk?
    My Ethernet disk is a LaCie Ethernet Mini Disk which supports Mac OS X.
    Thanks,
    Benny

    backups to NAS devices are not officially supported. the only exception is Time Capsule. It also works with an Airport Extreme base Station. There are hacks to enable backups to NAS but you use them at your own risk. see this link

  • Can Time Machine back up a second external hard drive that is attached via usb to a Time Capsule?

    Can Time Machine back up a second external hard drive that is attached via usb to a Time Capsule?
    I have a iMac with 10.7.4

    I want to back up the data on the external Hard Drive that is attached to the Time Capsule to the Tim Capsule using Time Machine.
    Thanks for the clarification.  Unfortunately, that will not work.  You will need to connect the drive directly to your Mac if you want Time Machine to backup the drive to the Time Capsule.

  • Can Time Machine back up both an iTune and iPhoto Libraries saved on a NAS disk?

    Can Time Machine back up both an iTune and iPhoto Libraries saved on a NAS disk, as well as the host drive on a Mac Mini?
    I would like to know if Time Machine could back up these Libraries from a NAS and the host/main drive of a Mac Mini onto an 3rd external drive attached by Firewire?
    Thanks

    no.
    time machine cannot backup networked drives.
    however, ChronoSync may be able to do what you want.

  • Can Time Machine back up data stored on a mounted external drive?

    Can Time Machine back up the data that I have stored on an external drive? It's mounted on the desktop but I can't seem to add it to Time Machine.
    Is it that Time Machine doesn't back up mounted External Hard Drives? If so, does anyone have a hack?

    then the problem is not those external drives. As I said, I've never seen this particular error message.
    Try using a different connection or a different port for your TM drive. If that doesn't help I'm afraid your options are very limited.
    Unfortunately, TM is configured in such a way that when anything goes wrong, there is usually nothing a user can do short of reformatting the TM drive and starting backups anew. I'm very much afraid that's what you are looking at.
    At least, I have no other advice to offer.
