Does time machine need a dedicated external hard drive or can I partition it?

I am trying to figure out the best way to back up my husband's computer.  He has too much data so I need to get about 80 GB off his computer on to an external drive and then need to back that up as well.  Right now I have two external drives one dedicated to time machine and one that backs up as a carbon copy bootable backup.  I think both external drives are 500GB, but he is on the computer and I don't want to fuss with having him get off right now.  I ordered an additional external drive so I have some where for his 80 GB of his data.  I can take one of the external drives currently used for time machine and partition it (mac OS journaled) and use one of the parts for time machine and the other for the 80 GB of data.  Will this affect our ability to get data off of time machine in the event his 5 year old hard drive dies?  The 80 GB of data includes important photos, so I would like them in two places.  I would consider cloud, but he is running Leopard and I know that iCloud only works with Lion.

Thanks to everyone for all your opinions and thanks to baltwo for this TM FAQ website.  Before asking this question, I browsed the internet and some people advised that a hard drive needed to be dedicated.  It seems now that if I partition the external drive and have a big enough drive that I should be ok.

  • HT204057 Why does Time Machine no longer support external hard drives connected to an Airport Extreme base station?

    I'm pretty sure that upto a few months ago I had a hard disk connected via USB to my Airport Extreme and I was able to backup all the computers on my home network. However, somehow over the last few months this had stopped happening. I am not able to select my network disks for time machine backup.
    There is a very unhelpful sentence on Apple's website which simply says it does not allow backup to hard disks connected to Airport Extreme via USB. Does anyone know why this is? Is there a way around this? Can I connect a drive to my desktop computer and have other computers backup through the network to that?

    This was never an approved configuration: OS X Mountain Lion: Disks you can use with Time Machine

    The above KB article indicates you can, though I have not personally tried it.

    Does your external hard drive have it's own power supply?  It should.
    Is your external hard drive formatted with the NTFS file system?  It won't work.
    It needs to be formatted either with Mac OS Extended or FAT32.
    (There are drivers available to add NTFS support to OS X but their quality is unknown, especially the "free" ones.)

    It would be much better if you had separate drives for the pictures and Time Machine backups.....but, if you want to use the same drive for both purposes, temporarily move the folder with the pictures to another location for safe storage.
    Run the Time Machine backup on the hard drive and verify that everything is working correctly. Time Machine will format the disk for you in Mac OS Extended (Journaled) as part of the backup process.
    Then move the folder with the pictures back to the hard drive with the Time Machine backups.
    When you have tested to make sure that everything is working again, then and only then should you delete the folder with pictures from the temporary storage area.
    Again....it would be much better to keep Time Machine backups on a drive just for that purpose, and other data on another drive for that purpose. This is clearly one of those times when the fact that you can do something does not mean to imply that you should do it.

  • Hallo ,why is it that when I delete a photo ,which is backed up by time machine and western digital external hard drive , that I am able to restore the photo okay but not the titles and descriptions . I have  a Macbook 4.1, mac osx 10.5.8 . Iphoto 7.1.5 ,

    QUESTION.
    Hallo , my question is ;whenever I delete a photo and restore it through Time machine and Western digital external hard drive , I am able to restore the photo but not the titles and descriptions . Western Digital inform me that it isn't their external hard drive problem and suggest that it is an Apple software problem ?
    I am using  a Macbook 4.1 , with Mac OSX 10.5.8 . I photo 7.1.5 , last modifie4d 01/05/2010 -universal . Should I be upgrading  Iphoto ?
    I hope that someone is able to help in this matter , as i have to restore 12000 photos !
    Thanking you in anticipation.
    Alan from Wigton

    Hallo  Kieth ,
    I am not quite ready to restore the full iphoto library , as I have days of work re - imputting titles,descriptions and enhancement . I hope that your suggestion works , as I use my Macbook basically to work with digital photography. Through time , I will need to delete my library to recover more disc space and I would hate to have to spend more time re - imputting titles and descriptions all over again .
    Thanks for your interest and advice.
    regards  - Alan

    Re Time Machine
    I have an external  hard drive with files I backed up manually over the past 2 years 1TB of memory.
    I am finally taking the leap to use Time machine to back everything.
    will I have to reformat that drive, thus wiping my previous back ups?
    can I split it the drive in two partitions?
    Also
    as I have two separate Macbook Pro's- one older than the other.
    OSX 10.68
    the other is
    OSX 10.75
    can I back them up separately?
    or even synch and merge files and folders etc? between the two?

    You CAN use a drive with files already on it to store Time Machine backups. But long term, that is not recommended. You do not need to reformat or re-partition the drive to do this. Once Time Machine Backups are established, you could remove the old files.
    But do not delete Time Machines files with the Finder -- that can cause it to lose its place and lose everything.
    With the cost of backup drives under US$100, it might be a better idea in the long run to get another drive. Best results from Time Machine is a drive about 3 times larger than the drive(s) you are backing up.

  • Time Machine and backing up external hard drives

    Time machine will not back external hard drives I have connected to my Mac Pro. It works fine with the 3 hard drives mounted in the computer. Is this the way Time Machine is intended to work or am I doing something wrong? Thanks in advance for your assistance.

    According to Disk Utility, GUID and AFP are both ok for a non-bootable drive with either CPU. The difference is when you want to make a volume bootable.
    Since TM volumes are not bootable, it shouldn't matter UNLESS you have some other bootable system installed on the drive.
    Right now, the drive on my Intel iMac is partitioned AFP and the one on the PPC powerbook is GUID. They both appear to be behaving themselves. The iMac has had one instance (since the last partition job) of a massive backup which occurred right after I changed the exclude list and the PPC has had no massive backups (other than the initial one). On that one, I built the exclude list BEFORE the initial backup.

  • With Time Machine I have an external hard drive formatted with Mac

    With Time Machine I have an external hard drive formatted with Mac. The record contained files windows. How to recover?
    Serious mistake: to connect a Mac to an external drive with data (important!) Windows, the warning appears: "You want to use the disk for Time Machine?" Wrong button, so in 2-3 seconds, the disk is formatted. Now Mac "sees" the disc but empty, Windows does not see it under "My Computer" but in "Disk Management" is reported as "hard core", "healthy", "GPT protective partition" Is there a way to retrieve the files? Sorry for my English Thanks

    I'm having a difficult time following, I understand English isn't your native language. You may have good luck with Google Translate.
    Also please read Pondini's Time Machine FAQs & Time Machine Troubleshooting.

  • Will Time Machine work with an external hard drive connected (via usb) to Airport Extreme?

    Will Time Machine work with an external hard drive connected (via usb) to Airport Extreme?

    Sorry, but this article is about 4 years old, and was printed based on preliminary information at the time.
    The bottom line here is that Apple does not officially support Time Machine backups to a drive at the USB port of the AirPort Extreme.
    If it works for you, great.
    You might want to review the Apple Support documents below, which are far more recent than the article you reference:
    http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html
    http://support.apple.com/kb/HT2038
    It is supported.....
    This is NOT correct. Please do not post false information on the forums.

  • HT201250 How can I migrate a Time Machine backup from an external hard drive to a new TimeCapsuls?

    I just got a 2TB Time Capsule.  I want to migrate my time machine backups on an external hard drive to the new Time Capsule.  I have about 430Gb of files to back up; I don't want to wait 7-8 days for the backup, unless I have to.  I am using OS 10.7.5 (forget which cat that is).  I have mounted the TC drive as 10.0.1.1; I tried to drag and drop from old to "data" on TC, but I get the error "The volume is the wrong format for a backup."  Any ideas how I can move my old files to the new, and bypass creating a brand new backup file?
    Thanks.

    Rather than do that, which means starting over from scratch, losing all your edits, organisation and so on, why not simply use iPhoto Library Manager to revert the Library to the older version? Easier, less destructive.
    The instructions on that are here
    If you really want to start over: you can access the Originals folder simply by going to your Pictures Folder and finding the iPhoto Library there. Right (or Control-) Click on the icon and select 'Show Package Contents'. A finder window will open with the Library exposed.

  • I had to reformat my OSX 10.5.8 and i can't restore my emails from my time machine backup from an external hard drive - only the latest (post backup) time machine back ups are available to restore. Please can any help

    I had to reformat my OSX 10.5.8 and I can't restore my emails from my time machine backup from an external hard drive - only the latest (post backup) time machine back ups are available to restore. Please can any help? I can find the mail folder in my libraries, but the Restore Button is grayed out

    OSX treats the reformatted drive as a different one; it's the same as replacing it, and the old one is no longer connected.
    See #E3 in  Time Machine - Troubleshooting to see and restore from the "old" drive.
    And, you may not want to restore via the Finder; see the blue box in #15 of  Time Machine - Frequently Asked Questions.

  • Does Time Capsule works as a External Hard Drive?

    Does Time Capsule works as a External Hard Drive?

    The Time Capsule works as a network drive.
    An external drive connects to your Mac using either the USB or FireWire ports.
    If your real question is to ask whether you can store other data on the Time Capsule drive....you can.

  • I threw out 24 time machine backups from an external hard drive into my desktop trash and now I can't empty my trash.

    I threw out 24 time machine backups from an external hard drive into my IMac desktop trash and now I can't empty my trash.

    Since you didn't mention what type of error message you were seeing, I'm going to guess on what is happening.
    I'm guessing that since you threw away Time Machine backups, that Time Machine is probably active on your Mac. There is a chance then that the files you tossed are marked as in use. You can't delete files that are in use.
    Try turning Time Machine off, then restart your Mac. Then try deleting them again.
    Once done, turn Time Machine back on.

  • Will Time Machine Back up an External Hard Drive Attached to my Mac Pro?

    Apple TV is GREAT, but it quickly filled up my hard drive. My thought is to take my folder that contains all of my personal files and put it on an 1TB external hard drive. I'd then "point" iTunes to where this new folder is. First, is that the right approach? Will that mess anything else up? Second, can I have Time Machine then back this external hard drive up? So, I'd like to have Time Machine back up my Mac HD and the external HD. If Time Machine won't do this, is there a good back up program for Macs that is very turnkey?
    Thanks in advance!!!

    If the drive is formatted +Mac OS Extended,+ yes. While it's connected, go to TM Preferences > Options. If it's listed in the exclusion box, just select it and click the minus sign at the bottom.
    If it's listed in gray, however, it's either formatted wrong or corrupted, and you can't remove the exclusion.
