After I had a defective hard drive replaced I found out my Time Mahince had only backed up until January.  So I am restoring my files through Mozy.

 

In the meantime I want to set up my Stargate external drive as my time Machine external backup.

 

I have tried going through the Time Machine setup protocol but cannot find this drive anywhere.   It is conected tthrough a USB and I have disconnected both the USB and power, then reconnected but the Stargate is nstill not detected.  when I go to Select Drive it says set Up Other Time Capsule with the WiFi symbol.  When I select it shows my airport Extreme and Internet selected.

 

Since I have no idea what this means, I need help.

    The Stargate drive your using is probably FAT formatted (windows formatted) if it does not show up in Time Machine. To make it compatible with Time Machine, you will need to format it to Macintosh Extended format in Disk Utility. Formatting a drive will erase everything on the drive, so make sure you back up anything that is on your stargate before you format it.

     

    To format your drive, open Disk Utility, click on your drive from the side pane, click the Erase tab, and click on the Format menu, and make sure that Macintosh Extended is selected and not MS-DOS FAT. Then click erase, and your drive should be compatible with Time Machine.

    Also make sure it has the GUID partition map scheme.  See Time Machine - Frequently Asked Question #5 for detailed instructions.

    Thank you both, for the advice.  As soon as Mozy finishes the restoration I will proceed to set up time Machine using your advice.

    So I would have an idea of what I need to do I went into Disk Utility but do not see the Seagate listed there.

     

    I have unplugged the USB & power, waited a while then plugged them back in but there is no change.  The Seagate is lit up but I cannot find it anywhere.

    I followed your instructions above but I could not erase the disc, nor partition it.  I get messages that Erase Failed and Partition failed.

     

    Volume Erase failed with the error:

     

     

    Couldn’t unmount disk.

     

     

     

    I have tried to backup and it appears to be doing so but then it stop, indicates another backup is scheduled shortly but also indicates the last backup was January 2012.

     

     

    I also read the FAQs and followed the instructions without luck.

     

    Any suggestions?

    That means something is trying to use it.

     

    But at least it did appear in the sidebar, so that's progress.

     

    Start from your Install Disc (if you're on Snow Leopard or Leopard), or the Recovery HD (if on Lion), and erase or repair it from there.  See the yellow box in Time Machine - Frequently Asked Question #5.

     

    And note that the oldest and latest backup information may not be updated until a backup is completed.

    Pondini...thank you.

     

    It looks like I am going to have to try the Recovery.  I have Lion 10.7.4.

     

    Being computer illiterate and having just gone through that Mozy restore, which didn't work all that well, I am a bit hesitant.  But, I will study the directions and follow them.

    I have not gone through the recovery stage because today Time Machine stopped showing "Preparing Backup" and it changed to Backing Up.  The gigabite indicator kept progressing toward 319Gs for most of the day.  then it stopped and went into an hourly backup mode:

     

    Preferences now looks like this

     

    However, whenever it backs up an icon identical to the Time Machine backup appears labled Time Machine Backups.  the clock like icon in the top tool bar does not turn as it previously did whenever a backup was in progress,

     

    Further, the fact that my last backup prior to this was January 4, 2012 indicates that is when I shut down my system and was away for three months.  When I returned I hooked up my laptop and it appeared Time Machine  was working.  But obviously not.

     

    So, whenever I take my laptop on the road, what is the procedure for disconecting Time Machine?   Just turn it off or eject it?  Aalso, even if it is disconnected, does it still need power?  When I went away for three months I shut down all electrical power.

     

    Thanks

    Ah, good.

    That should happen only for backups made over a network.  Is your external HD connected directly to your Mac?   If so, was it connected to a Time Capsule or Airport Extreme previously?

    Yes, that's new in Mountain Lion.  It only spins during the actual copying, not while it's preparing or cleaning-up at the end.  We don't know yet if it's a bug or (bad) new design.

    Those backups may have all failed.   Hard to tell now, of course.

    Eject if first.  If you don't, the backups can be damaged (the directory structure, etc.).

     

    Aalso, even if it is disconnected, does it still need power?

    Nope.

    Pondini...Thank you for all the help.

     

    It was originally connected through an Airport Extreme and worked fine until recently.  Or at least I thought it did.  When I started to notice Timw Machine wasn't working I tried to re-configure but Preferences would not recognize it.  I then plugged it in through a Griffin docking station (both my USB ports are occupied) and it recognized it right away.

     

    But, just as I think all is well, I get this message:

     

     

    So, I guess it is time to buy a new, and larger external drive.

     

    Any suggestions for that purchase?

     

    My Mac internal has a 499GB capacity and I currently have used about 319G.  I have over 13K of pictures on my system.

    Aha!  That explains it.

     

    I hate to have to tell you this, but backing-up that way is unreliable and not supported by Apple.   See:  Using Time Machine with an Airport Extreme Air Disk.  The backups may have been damaged at some time while you were backing-up that way.

     

     

    Time Machine stores your backups differently when they're done over a network.  It puts them in a rather odd container called a sparse bundle disk image, rather than at the top level of the drive as it does when backup are made locally.

     

    If you then connect that directly to your Mac, Time Machine will continue backing-up to it, but some other things won't find it, since they're not looking for a sparse bundle.   In those cases, you must manually "mount" the sparse bundle by double-clicking it in a Finder window.  See the blue box in Time Machine - Frequently Asked Question #17.

     

     

    So, I guess it is time to buy a new, and larger external drive.

    Maybe.  How large, and how old, is it?

     

    It varies widely (see Time Machine - Frequently Asked Question #1), but a "rule of thumb" is, TM needs 2-3 times the space as the data it's backing-up.  And has a 3-year waranty.

     

    If your drive is more than about 3 years old, it may be a good idea to get a new one anyway.  They don't last forever.

     

    If you want to keep it, your best bet may be to erase it with Disk Utility and let Time Machine start fresh, backing-up to it directly.

     

     

    Any suggestions for that purchase?

    OWC has a good reputation, both for hardware and support.

     

    I recently got one of their Mercury Elite drives: http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATA_FW800_FW400_USB, as have a number of other users, with good results.

     

    You can also buy enclosures and drives from them separately.

     

    But any decent-quality drive will work well.

     

     

    A much more convenient alternative would be an Apple Time Capsule.  It's more expensive, since it also includes a wireless router (like your Airport Extreme), but was designed for wireless Time Machine backups.

    Pondini...thank you again for all the good advice.  Very nice of you to spend time explaining things quite clearly.

     

    I will be getting a 1T drive and configuring that as my Time Machine.  I have purchased some more space with Mozy and I will probably use my Seagate as another backup just for my pictures.  Perhaps back them up to it once a month.  Further, I am backing up my documents and financials to a thumb drive for quick retrieval.
