Clicking "encrypt backup disk" crashes Time Machine Preference Pane

Everytime click "encrypt backup disk" Time Machine Preference Pane crashes on MacOS Lion. I have a 2TB disk partioned into 2x1TB volumes, could this be the problem? Are there any other reaons that might cause the crash?

It sounds a bit like your backups may be corrupted, and TM is having a tough time figuring out what's on the drive.
Try doing a +*Repair Disk+* on your TM drive, per #A5 of the Time Machine - Troubleshooting *User Tip* at the top of this forum.
Then do a "full reset" per #A4 there.

  • Do I need to encrypts backup disk for Time Machine to encrypt backups?

    I have a new LaCie disk that I want to dedicate as my backup.  In case it is ever stolen, I don't want others to be able to retrieve files.
    I've seen screen shots where Time Machine has a checkbox "Encrypt backups".  This seems like what I want, right? 
    But I'm first erasing the disk to get it ready for backups.  Do I choose:
    "Mac OS Extended (Journaled)" or
    "Mac OS Extended (Journaled, Encrypted)"
    I.e. will the option in Time Machine not appear unless I format the drive as encrypted?
    Thanks.

  • I am changing to a larger hard drive on my Mac. Can I copy the Aperture library from my backup disk running Time Machine without loosing anything?

    I am installing a larger harddrive on my Mac. Can I copy the Aperture library from my backup disk running Time Machine without loosing anything? I am getting help migrating everything else on to the new harddrive, but since copying the 350Gb Aperture library takes a lot of time, I am planning to do that part myself.

    I found the following information on Time Machine help about restoring Aperture library from TM
    Restoring Your Aperture System
    If you buy a new computer or use another system at a different location and want access to the Aperture library, you can install Aperture and then transfer the library from your vault (on your backup disk) to the other computer. If you experience equipment failure or other unexpected events, such as fire or weather-related damage to your equipment, you can easily restore the entire library to your new computer from a backup disk.

    Choose File > Vault > Restore Library.The Restore Library dialog appears.
    Choose the vault you want to use to restore your library from the Source Vault pop-up menu.If the vault doesn’t appear in the Source Vault pop-up menu, choose Select Source Vault from the Source Vault pop-up menu, navigate to the vaults location in the Select Source Vault dialog, then click Select.
    Click Restore, then click Restore again.

  • I need to configure a new hard disk as backup disk for time machine. The set up program is running and it says it will take 9 days to backup about 56 GB. Is it normal ?

    5 hours to do 6 GB of transfer is NOT normal, even for USB 2.0 so there's something wrong here. I'd say cancel it, wipe the drive and then test the integrity of the drive. Do some file transfers over to and see if it's behaving normally. It could be a bad USB cable, it could be a bad drive or bad enclosure. As it's new, I suspect you haven't really put it through its paces yet and it's important to do that first before commissioning it to serve as your "reliable backup."

  • HT201250 Is it possible to use Dropbox or Microsoft OneDrive as the backup disk for time machine?

    I have a MacBook Pro for which I have not set up Time Machine. I have a Dropbox account and a Microsoft OneDrive account, each with plenty of space to serve as backups. Is it possible to use either of these as THE backup disk for Time Machine? It doesn't appear intuitive from Time Machine on my MBP.
    Thank you.

    No. Time Machine does not work with "cloud" drives.

    Hello edjhsu,
    Unless the drive is in a format that isn't compatible with Time Machine, the files will not be overrwitten. However it is typically a better idea to keep your files and your backup separate, especially since files on the Time Machine drive will not be backed up by Time Machine.

  • Remove disk from backup disks in Time Machine, old backups no longer accessible

    I accidentally removed a disk from my backup disks in Time Machine. It said it wouldn't delete any backups, but after reconnecting it, I cannot access any previous backups through the Time Machine interface and it says "Latest Backup: None". The data is still visible on the drive.
    What can I do? I really need these backups.
    PS This poster appears to have had a similar problem but was never resolved: https://discussions.apple.com/thread/4175446

    See Pondini's TM FAQs for starters.

  • Have backup disk, but Time Machine is not recognizing it...

    I have tried 3 different external hard drives, all of which have come up in Finder and I am able to explore them, but when I ask to set up Time Machine, it has no options of any backup disks for me to select? Help! Right now I have Western Digital 500 GB drive connected.

    Using Disk Utility. First, make sure there is no data on the drive you want to keep. Everything that's on the drive already will be destroyed in the conversion process.
    Open Disk Utility (from the Applications > Utilities folder) and select the backup disk from the left-hand pane. Make sure you select the correct disk, otherwise you may lose valuable data! In the main section of the window, select 'Erase' and make sure that "Mac OS Extended (Journaled)' is selected. Change the name if you want, then click 'Erase...'.
    When this is complete, your freshly formatted disk should appear in the Time Machine preferences.

  • My primary HD is shown as a 'Backup Disk' in Time Machine . . .

    I was a longtime user of SuperDuper and want to try Time Machine.
    Is the primary hard drive (mine called Prime) supposed to show up as a 'backup disk' in the Time Machine preferences?
    See image:
    I want to back up to two other hard drives, Time Machine (On Site), and USB Back-Up. How does one identify the disk to be backed up? Does Time Machine default to the one containing the active system?
    Thanks.

    Hi Edward,
    From the screenshot, it looks like you have 3 active backup disks.  This article has some information on using multiple disks for backup:
    OS X Mountain Lion: Use multiple backup disks
    http://support.apple.com/kb/PH11452
    Time Machine rotates the backup schedule among the disks. For each backup disk, Time Machine backs up everything that’s changed since the last time that backup disk was used. If you’ve clicked Options in Time Machine preferences and designated items that should not be backed up, the list of excluded items applies to all backup disks.
    Additionally, here's some info on the disks that can be used with Time Machine:
    OS X Mountain Lion: Disks you can use with Time Machine

    I hope this helps!

  • How do I choose a backup disk for Time Machine?

    I'm using a 1T Seagate backup disk with 3 partitions to back up on Time Machine. Very suddenly, when it was mounted, the Time Machine icon disappeared, and the Time Machine Partition turned into the generic black Seagate partition-- same as the other two partitions. I ran Disk Utililty; supposedly, everything is fine. I didn't need any of the previous backups, so I reformatted the backup disk. In choosing a disk to use in the Time Machine preferences, I chose a partition. It did perform the backup, and the Time Machine icon was on the desktop while it was backing up, but when I ejected the disk and then plugged it back-- there was the generic icon again.
    Also, when I cicked on command e, previously, I was given the option of ejecting one or all three partitions. Now, everything just ejects immediately. Seems like there is a glitch somewhere. In the Time Machine Preferences, the disk with the Time Machine icon at the top of the preferences has an option to select disk and then an option to remove. Why would I remove that disk? Very confusing.

    The option to remove the disk in the TM preferences is so you can use another disk if you want.

  • Can I use multiple backup disks using time machine

    I know I can back up multiple macs with TC and TM. but can I attach a TC and another hard drive (via a NAS) and have TM back up to both..... just for redundancy security.

    Loaded question.
    Some NAS drives will support Time Machine backups and some will not, so you would need to check with the drive manufacturer in advance to make sure that the drive you were interested in will work correctly.
    Time Machine on one given Mac can only backup to one destination drive at a time.
    You can change the destination drive(s), but you would have to do this manually in Time Machine Preferences.
    Kind of clunky, but it would work if you remember to switch drives each day or week, etc.

  • I have an iMac OS X 10.6.8 and have problems with the backup Disk for Time Machine disconnecting itself with the message that I ejected it improperly.. It ejected itself - why?

    I have an iMac OS X 10.6.8 and have problems with the backup drive to Time Machine ejecting itself and so does not automatically backup the way it is meant to do. It is connected with an USB cable to my iMac. What could cause this - malfuntioning drive?

    The "iLife" apps are not part of any Mac operating system install and are a separate purchase.
    Once you get past 10.6.6 you can purchase and download iPhoto, GarageBand and iMovie. iWeb and iDVD have been discontinued.
    Snow Leopard 10.6.6 and higher include the App Store application which is what you use to purchase Lion.

  • Can I use a "Click Free" backup drive with Time Machine

    Can I connect my Click Free portable hard drive backup to my  Intel IMac running Lion, and use time machine and not the Click Free backup software? I'm guessing I might have to erase the software from the ClickFree drive. This ClickFree hard drive is for Mac as well as Windows.

    Then it is likely formatted as FAT32 and can not be used with TM until reformatted to HFS+.
    It should work after reformatting, use disk utility to erase the drive and set the format as MAC OSX Extended (journaled)

  • Backup disk for Time Machine not available after recent update.

    Please Help!!!
    I just did and automatic update that consisted of about 6 items, now my external hard drive is not even recognized! Long story short, Time Machine can not find my external to do a backup.
    I have already done all the unplugging and restarting and searching for the disk... Nothing!
    Plugged in, my external is Lit and seemingly functioning.
    There has GOT to be an easy fix for this one!
    Again, HELP!
    =Marc

    Check that the data cable is securely inserted at both ends.
    Try a different cable.
    If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
    If you're connecting it directly, try a different port.
    Test the drive with another Mac. Test another drive with this Mac.
    Boot from your recovery partition (Mac OS X 10.7 or later) or from your installation disc, and launch Disk Utility. Is the drive recognized?
    If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive has failed. You may be able to salvage the mechanism by removing it from the enclosure and installing it in another one, or in a drive dock.
