Using Time machine with an external hard drive and AEBS???have a

I have a 500GB external hard drive that I have connected to my AEBS by USB. Recently upgraded to Leopard but cannot get time machine to see my hard drive.
The base station is 802.11n.
Is this possible?
Have read a few other threads and can't seem to get to the bottom of it.
Thanks,
T

In addition, when you get Time Machine to be able to see your external drive connected to AEBS, in TM prefs exclude all but one small folder from your hard drive (say, /User/Library) and allow TM to do its initial backup. This will create the sparsebundle (resizable disk image) that TM uses to back up to a network drive.
Then turn off Time Machine, unmount the USB drive and reconnect it directly to your Mac, mount it, set TM prefs to use the sparsebundle that newly-mounted drive, remove previously excluded items from TM's exclusion list, and turn TM back on. TM will then back up everything much more quickly than if connected wirelessly.
After that, you can return the USB drive to the AEBS. Incremental backups take much less time, so the slower connection won't matter as much.

  • Intermittently using Time Machine with an External Hard Drive

    Ok, Kappy answered some questions I had about how Time Machine works with an external hard drive.
    After doing more reading about Time Machine, I found out that a person can, for example, leave the drive powered-off for a couple of weeks and only periodically or intermittently use Time Machine for back up. However, in the online article I read dated 2009, the author suggested that he didn't know how well Time Machine would work making up for the two weeks, or however long, no files had been backed up.
    Specific questions: I have 10.6.3 SL (I have not yet been brave enough to download 10.6.4) and a 4 month old iMac. 1) Have any of you had experience with only periodically using Time Machine for back up and 2) with my current system would you think I might run into some trouble if I only intermittently backed-up using Time Machine?
    Thanks for reading this and thanks if you feel my questions warrant answering.
    Note: I do have another external hard drive where I occasionally manually back-up photos, gifs, music, etc.

    If you go several days between backups, Time Machine may have to do a "deep traversal," comparing every folder on your system to the backups, to determine what's changed and needs to be backed-up. This depends on the volume of changes, so can happen after an OSX update, but in other circumstances might be after several days. This isn't a big problem, but it does take longer, and the more data you have, the longer it takes.
    Worse, after an extended period, Time Machine may do a new, full backup of your entire system, rapidly filling-up your TM drive.
    If that's the way you want to back up, Time Machine is not the backup app for you. One of it's main features is the way it can do quick hourly backups of what's changed, so you have an excellent chance of recovering a previous version (or versions) when you change or delete something in error, or a file comes up corrupted, or your Mac fails.
    Why don't you want to just leave the drive connected and Time Machine running, to protect you best, as it was designed to do?
    For alternatives designed to do less frequent backups, see Kappy's post on Basic Backup.

  • Is it possible to use Time Machine with an external hard drive for two separate computers?

    I'm looking to purchase an external hard drive to use as with time machine as a backup for two separate computers.  I'm not sure if I should buy 2 EHDs and dedicate one to each computer, or if Time Machine has the capacity to back up both computers separately.  Anyone have any experience with this?
    Thanks!

    You can make two partitions on a single drive and dedicate one to each computer.
    The pic is of a single external usb drive with three partitions( a Time Machine and two image backups) for two computers

  • Using Time Machine with two external hard drives

    Hi. I use Time Machine to back up the hard disk on my MacBook Pro onto a Western Digital external drive. For secure storage of family photos and things we don't want to lose, I would like to do the following:
    For a week or two, back up my MacBook Pro onto a Western Digital drive. Let's call this WD Drive 1. Then walk downstairs and put WD Drive 1 in a fireproof safe. For the next week or two, back up my MacBook Pro onto a different Western Digital drive. Let's call this WD Drive 2. Then put WD Drive 2 in the safe, take out WD Drive 1, and use WD Drive 1 as the back-up medium for the next week or two. Then keep alternating between WD Drive 1 and WD Drive 2 every couple weeks. This way, I will always have up an to date back-up on the WD drive that is connected to the MacBook Pro, and I also will have a two-week old back-up on the WD drive in the safe in case of a fire or something.
    Can Time Machine be used in this manner, alternating between two different external back-up disks? Will Time Machine "know" when I change external drives and manage all back-up files appropriately?
    Thank you!

    Yes. Each drive will have an independent set of backups; and each will be a complete "snapshot" of the way your system looked at the time of the backup.
    When you swap drives, the first backup will be somewhat longer, and may involve a "deep traversal," while Time Machine "catches up" with all the changes since the last backup to that drive.
    And try not to go too long between swaps; it's undocumented, so we don't know the exact parameters, but after at least 10 days (apparently), Time Machine may do a new, full backup instead of an incremental one of changes only.
    And you only need to worry about Time Machine deleting old backups if you've deleted the originals from your system; TM will never delete the backups of anything that's still there.
    But . . .
    As MusicWind says, thats' probably not the best strategy. One of the reasons you want dual backups is because no hardware is perfect -- it all fails, sooner or later, right? Similarly, no app is perfect, either. The "works" of Time Machine are more complex than most backup apps; it's pretty reliable, but if you're going to have dual backups, you're probably a bit safer with a different app for your secondary backups.
    I don't know about SuperDuper, but CarbonCopyCloner does have an "archive" feature, where it will keep copies of things you've deleted. I've never used it, so don't know just how it works.
    Also see Kappy's post on Basic Backup, complete with links to the web sites of each product.
    p.s.: Don't try copying Time Machine's dated folders; you'll get a complete copy of your entire system.

  • I am using Time machine with an external hard drive...

    for the first 6 months it was working great no problem...now the time machine logo in the top right of the desktop just keeps spinning constently..i stop it manually and starts again and doesnt stop until i do. Botht eh hard drive and the iMac have been restarted. any thoughts? Thanks

  • Using time machine with 2 external hard drives

    I am setting up time machine for the first time on my iMac.I have two external HD's - one with all of my files saved onto (HD #1), and then one that is empty that I'm hoping to use as my backup drive (HD #2).
    Is there a way to set up time machine so it backs up the content from one external HD (HD #1) to the other external HD (HD #2)? Or will time machine only back up the files on the actual computer's HD and not an external one?
    Any advice is much appreciated!

    Time Machine will backup all external HD's (that aren't a TM drive) connected to the computer. If you want to exclude those drives or files or folders you simply select them in the TM preferences.
    For example I have an external HD connected to my iMac that has all my photos, movies and music. I have a second drive also connected that is my Time Machine Drive and I also have a third drive connected that is my Bootable Clone. I have excluded the Bootable Clone from my Time Machine backups for obvious reasons however allow the drive that has the photos, movies and music to be backed up on TM.

  • Can I increase the capacity of Time Machine with an external hard drive connected to Time Capsule?

    Can I increase the capacity of Time Machine with an external hard drive connected to Time Capsule via the USB port?  My current Time Machine has a total capacity of 1TB.  I'd like to double or triple its memory.  I don't want to use the external hard drive in lieu of the Time Capsule hard drive.  I'd like to use it in addition to.  Just don't know if/how it's possible.
    This is another one of those questions that I've searched the web for answers, and have gotten tricky answers back.  So now I'm trying to introduce a clean slate to the mix.
    Thank you for your time!

    Well, what you mentioning is possible.  However, I don't know whether it's supported (as in, "easy to set up.").  Time Machine officially supports backing up to a locally attached drive, to a machine running a Time Machine server (i.e. running OS X Server software), and to a Time Capsule.  I don't know that it officially supports a drive attached to an AirPort or to a Time Capsule.  Though I know some people have gotten it to work.
    Best I can say is to try it.  Plug the drive into the Time Capsule, ensure it's shared on the network, and then try and set it as a backup target from a machine in the Time Machine backup panel (you'll need to ensure it's mounted first).  If it works, you're all set.

  • I use Time Machine with an external hard disc which has worked perfectly for some years.  Recently Time Machine has aborted backups if the screen saver starts when back-up is in progress. I use a Maxtor OneTouch4 back-up system.  Any ideas?

    Has Apple recently up-dated my OS (Lion) such that every time the screen saver starts it disables Time Machine.  I have to switch-off the computer and re-start in order to undertake  a back-up.  I have now switched of all screen savers.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem(s)?
    After testing, reboot as usual (i.e., not in safe mode.)

  • HT3275 Time Machine says my external hard drive does not have enough

    Time Machine says my external hard drive does not have enough space for the current backup.  It needs 34 G out of a 250G hard drive.  All that is on the drive is earlier backups.  I recently added memory, which may confuse Time Machine into thinking it is a new computer.  How can I erase old backups and complete this one?

    See #C4 in Time Machine - Troubleshooting. 
    If that doesn't clear it up, how much data is on your Mac?  If TM is only trying to back-up 34 GB, it should be able to delete old backups to do that (assuming you're running Lion).
    It sounds like your backups may be corrupted.  Try to repair them, per #A5 in Time Machine - Troubleshooting.
    I recently added memory, which may confuse Time Machine into thinking it is a new computer.
    If that's all you did, no.

    Just erase the drive per #1 or #2 of Using Disk Utility.

  • Using Time Machine to restore external hard drive data

    I have been using a Mac Mini running 10.6.8 for years as a media server.  I have always been very careful to maintain backups of everything, and the inevitable did happen - the hard drive containing all my media did fail.
    To clarify my set up, my Mac Mini internal hard drive is insufficient to store all my media, so I have been using an external 2TB drive to store it.  I then set up Time Machine to back up both the Mac Mini and the 2TB external drive to a second 3TB external drive.  Now that the 2TB drive with my media has failed, I seem to be having problems restoring all the media from 3TB drive.  This is because the Time Capsule interface is designed to display finder windows at various points in time so you can go back to when your missing files existed and restore them.  The problem is that I need the entire contents of the dead 2TB drive restored to a new drive, but I can't open a Time Capsule window that shows the contents of the old drive.  I have tried opening /Volumes in a finder window, then invoking Time Machine, but my dead hard drive does not show up in the list of volumes.  When I open the 3TB drive in a Finder window I can clearly see that it has backups of the 2TB drive, but they are spread out among 83 different snapshots of various dates.
    How can I use Time Machine to easily restore the entire contents of the dead 2TB external drive to a new external drive?

  • HT201250 Using Time Machine as an external hard drive

    I backed up my iMac with an external hard drive using Time Machine; can I delete all the data from my iMac now? My real goal is to use the 1TB external hard drive I just got to store all my music, photos, and other files on. I want to clear all the space off of my iMac, and may by a new Macbook. I want to be able to access all the files from my original computer on either, while cleaning out the iMac. Was it pointless for me to use Time Machine? Thanks so much for the feedback!

    You cannot use the files in the Time Machine backup and while it is possible to partition or otherwise use free space on the Time Machine drive as external storage Apple does not recommmend it. Your best solutions are either replace the existing hard drive in your MacBook Pro with a larger capacity drive or add a bus powered external HD. A 1TB USB 2 or 3 drive runs just a bit over $100 and the internal drive about $20 less. In either case remember the Time Machine drive should have two to three times the space of the drive(s) it is backing up.

  • Backing up iPhoto pics without using Time Machine or an external hard drive

    I cannot figure out how to back up my photos on my one year old MBP. I haven't gotten around to buying an external hard drive (so many choices and there seems to be problems with every one I look at - advice?), but at this time the only important data on my MBP are my photos (approx 9 GB). I've searched the various forums, looked in The Missing Manual (Mac OS X Leopard), and read the help sections on the computer but cannot seem to find step-by-step directions for backing up to a flash drive or a few DVDs. Thanks for your help.

    Welcome to the Apple Discussions. Unless you have an external storage source you can't backup your photos.
    You could burn the image file to a DVD disc by selecting about 4GB of files in iPhoto and exporting the photos to a folder on the Desktop and burning that folder to a DVD with the Finder.
    Or select about 4GB worth of files in iPhoto and use the Share->Burn menu option. That will give you a DVD disc with a mini iPhoto library on it that contains those 4GB of original files, their modified versions and all metadata associated with them.
    Click to view full size
    When you want to copy any of the file on the disc back into iPhoto mount the disk in your optical drive and it will show in iPhoto where you can select what you want and drag to the Library icon to copy them back into the library.
    CLICK TO VIEW VIDEO
    I'm sure you have other documents on your MBP that you need to backup. An external FW hard drive for use as a Time Machine backup drive is essential if you value your photos and other data on the hard drive. Consider for a moment what you would have to do to get back where you are right now if you lost the entire internal HD.
    TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier versions) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
    I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. There are versions that are compatible with iPhoto 5, 6, 7 and 8 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
    NOTE: The new rebuild option in iPhoto 09 (v. 8.0.2), Rebuild the iPhoto Library Database from automatic backup" makes this tip obsolete.

  • Use time machine to backup external hard drive (not main one)

    Hi all,
    I've searched for information on this and getting nowhere. Not sure if it's possible, but I have two USB hard drives now as I've run out of space on my laptop. So therefore I really use one of the hard drives for my main storage and drag files across to the other one to back that up.
    It would be easier if I could just use time machine to back up the one external hard drive to the other. I don't want to just replicate what's on my laptop hard drive.
    Does anyone know if this is possible? Would appreciate any help.
    Cheers
    Paul

    Thanks for your reply V.K. much appreciated.
    I have gone into the options and I can see my external drives there, but for some reason I can't remove them from the exclusion list. I can add and remove the Laptop HD from this list, but for some reason the "-" button becomes disabled whenever I select the external Hard Drives.
    Is there a reason for this? I've been using both drives for a while, so they are both Mac formatted.
    Thanks again.

  • How do you use time capsule with an external hard drive

    I would like to use time machine to back up to my external hard drive. 
    When I tried to set it up it said it would wipe out everthing currently on it to start using it.
    I do not want it to wipe our what I have currently have on the hard drive.  Any suggestions?
    I do have icloud.  Can I back up using time machine to that?

    Purchase another external drive. Time Machine will only back up to a drive formatted as Mac OS Extended (Journaled).

  • I want to use elements 11 with an external hard drive and need some help.

    I have a macbook pro and was fine using iphoto 09 as my image manager and editor. I soon filled my hard drive and purchased a 1tb external hard drive. I moved my iphoto library to the external drive while keeping iphoto on the macbook. I recently installed elements 11 and was using it as an external editor with iphoto. I began to play around with the organizer and found that I liked it. My question is how do I move my iphoto library to elements 11 organizer while still keeping the photos on the external hard drive.

    If you import from iPhoto into Elements Organizer, the files will be copied to your hard disk and all the organization done in iPhoto09 will be carried forward to Organizer catalog. This can be done if you have enough space on your hard disk. However if you want to use Organizer solely + not create duplicate copies of your images, you can import photos directly from the Hard Disk. Ensure to write all metadata to files within iPhoto so that when the same photos are imported into Organizer, the tagging done is brought along.
    Thanks
