Time Machine to back up external hard disk

Hi,
I 'm going to add an external hard disk to my iMac for storing music files and another one as backup. Not sure if Time Machine is possible to do auto back up for the external harddisk rather than the one built inside the iMac?

provided the external is formatted mac os extended, TM will back it up along with the internal drive.

  • How do I encrypt my Time Machine Backup on the External Hard disk

    I have taken a backup of my data onto an external Hard Disk. I have used the Time Machine application to take the back up.
    I want to encrypt this time machine backup on the External Hard disk. Any suggestions???

    Many thanks!
    Have you selected the disk?
    You can only encrypt disks that are directly-connected (ie, not on a network), with the GUID partition map scheme.
    Put your mouse pointer on the dimmed checkbox, and after a moment an explanation should appear.

  • Encryption of Time Machine backup on an external hard disk

    I use an external hard disk (not Time Capsule) for my Time Machine backup. How can I encrypt this external hard disk. I didn't find such a function in the Mac OS. Thanks a lot for any hint.

    Click here and follow the instructions. The image's contents can't be accessed without the password, but the image file can still be deleted.

  • 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.

    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.)

    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.

  • I am running my first backup on Time Machine using a Seagate external hard drive with a thunderbolt adapter and cable.  I have a MacBook Pro 2011. It is backing up 11GB, and is telling me it will take approx two days. Is this normal?

  • 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.

  • 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

  • Is there any way to create a time machine backup to an external hard drive with content already on it?  I have a hard drive that i have used for pictures but when i try to run a backup it says i need to start from a blank drive. Can i get around it?

    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.

  • 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 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.

  • 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 capsule also back up external hard drives?

    will time capsule also back up external hard drives?

    Yes. If you're using Time Machine, open its preferences and ensure the drives aren't excluded; Time Machine can't back up drives in some formats, such as FAT32.

  • Is there a way to get my photos off an old time machine backup from an external hard drive?

    Is there a way to get my photos off an old time machine backup from an external hard drive?

    You will have to connect the Time Machine HDD and click on the Icon.  You will see one folder called Backups.backupdb.  Click on that and you will have to continue until you find the home folder.  The iPhoto library (where the pictures are, not the application) will probably be in your pictures folder.  You will have to drag that to your desk top.  Then you will have access to individual images.
    Ciao.
