Two Mac computer in one Time Machine ? Possible?

Hi
Does anyone know that can I back up two computers in one Time Machine External HD? I have one Imac (PPC) and one MAcbook (intel). For both of them I'd like to make one Time machine HD. Does it work like that or do I need to back up two seperate TM HD for each of my computers?
Many thanks...

tur,
There are multiple options for backing up 2 machines to one external drive. Remember that Time Machine is smart enough to recognize different machines and stores the backups in different folders.
1: Connect your external drive to your main machine and then use Personal File Sharing to share that drive on your network. Keep in mind sharing the drive over the network will degrade network speed while Time Machine is working (Not such a big deal if you use a wired network).
2: (The option I use) Run Time Machine on the first computer, eject it the drive, and then plug it onto the second machine and run time machine on that computer.
I use option 2 because I have a machine I use as a media center and do not need regular backups of. I only back it up when I add files.
A third option I have not had any experience with is using Apple's new Time Capsule.
I hope this answers your question.

  • Two different users.  One Time Machine Backup?

    I have two user profiles on my iMac. I'm just wondering if Time Machine backs up both profiles when I'm logged into one or do I have back up each profile individually?
    Thanks.

    It will backup virtually the whole contents of your internal hard disk, so no worries. That's whether you are logged into a specific user account or not.
    Cheers!

  • I just bought and backed up my computer and time machine with a "Seagate BackUp Plus for Mac". Now my time machine is empty. Panicked. can anyone help?

    I just bought and backed up my computer and time machine with a "Seagate BackUp Plus for Mac". Now my time machine is empty. Panicked. can anyone help?

    Lets start over...
    Please restart the network.. shut down everything..
    Restart in order.. modem.. router.. if different to TC.. or TC.. client devices.. wait 2min between each startup.
    If the TC does not show up on the computer, in finder.. then we need more info.. what OS are you running?
    Does the TC show up in Airport utility? Are you running wireless or ethernet?
    If you still have issues.. plug the TC directly into the computer by ethernet.
    Do a full factory reset of the TC.. and see if it now shows up.
    Please tell us exactly what model TC it is and how old.. the A1xxx model number from the base will help if you don't know.
    You take a screen shot of the TC opened in finder.
    eg..
    My TC is named Tardis4.. click on it.. and then open the data folder.. on this one called Tardisdata.
    Then take a screen shot of it so we can see what the problem is.. screenshot.. with area selection.. control + shift + 4 .. the picture goes into the desktop.. and then you click the picture icon in the posting web page controls and select the picture.

  • I work with a Mac & I had to restore my computer for my time machine back-up.  When I attempt to open/edit a photo with either camera raw or photoshop I get the following error message: Error 150:30 , it also sys that licensing for the product has stopped

    Unfortunately when Adobe products are restored from backup, especial CS4 and especially Mac, it breaks licensing.
    There is a python script included in the license recovery kit that should work if you are familiar with Terminal.
    If not, you must reinstall your CS4 suite.  You don't need to delete your preferences, so it should be the same as before.

  • Mac OS 10.6/Time Machine cannot 'see' HD to re-install or restore

    Upgraded my Mac Mini to Snow Leopard a couple weeks ago and had no problems. Then yesterday the computer froze up (the mouse still moved and icons in the dock expanded with the mouse but NOTHING was acknowledged when clicking to tabbing to any commands; could not even click from screen to screen for various functions that were currently open ... yet the mouse moved fine). Tried to restart computer and all I get now is a gray screen with a flashing file folder with a question mark in it.
    Have tried all attempts listed here and in Support to (1) re-install Mac OS X 10.6 from the original disk, and (2) restore my computer from my Time Machine. Have tried many, many times now for both options and in ALL cases the computer cannot see or find my computer. The only disks it can find to re-install or re-store to are the 2 external hard drives I have. If I disconnect these, the computer can find NO disks to re-store to. (I've now let my system search for disks for over 3 hours this time around, and it still cannot find any disks to install to.)
    So what's happened to my Mac Mini and "where" has this disk gone to? Why can't my Time Machine or Mac OS X installation disk find (or see) my Mac Mini?
    (Really do need a new computer and was seriously thinking about just buying the new iMac this week, so maybe this is the sign. But would still like to get the last few files off my Mac Mini that I was working on when it crashed -- don't think Time Machine actually had time to back these up ...)
    Cheers, and thanks for any suggestions and help!

    It sounds like you are having trouble with your internal Hard Drive.
    Whilst this is quite serious, sometimes you can fully recover from the situation, depending on what happened.
    One of the most useful and reliable rescue utilities is DiskWarrior:
    http://www.macupdate.com/info.php/id/11707/diskwarrior
    If you are lucky it may be something as simple as a damaged HFS+ wrapper, which can be repaired and have you back up on your feet again in relatively short order.
    It pays to periodically check the *S.M.A.R.T. Status* of your drive, at the bottom of *Disk Utility.*
    This is a self diagnosis function that may indicate impending problems. However if the disk has sustained physical damage, such as caused by a hard knock, nothing will redeem it.

  • How do I make Lion Server support more than one Time Machine disk?

    Under Snow Leopard Server, I had two disks set up for Time Machine backups. This came about as I'm running a Mac Mini with the 500 GB internal drives which turned out to be insufficient for one of the connected Macs which uses a terabyte drive. I then added an external 6 TB drive and made it a Time Machine destination too. Worked beautifully. When I upgraded to Lion Server the external large drive was no longer available for backups and the interface for configuration within Server only allows for one drive to be in use at a time. Any suggestions (short on reverting to Snow Leopard) as to how to re-enable having both drives available for networked Time Machine access?
    Thanks!

    Hi Adam,
    Before I even realised that the Server app had a setting for TM, I just configured TM backups on my (SL) clients as I had done in SL.
    I shared the drive(s) on the server I wanted to use.
    For each client, I mounted the appropriate shared drive containing its sparseimage file, then set TM on the client to use that drive.
    Then I unmounted the shared drive and started TM.
    It mounted the remote drive (without displaying it in Finder) and opened the sparseimage, showing the "Time Machine Backups" volume on the desktop.
    So you could use any drive attached to the server to backup any client.
    It worked fine for me.
    In the end, I changed my clients to use the (single) shared "Backups" volume which Server.app creates because I can fit all my stuff on one drive.

  • Time machine - possible to recover deleted backup files that have yet to be overwritten?

    I recently had to wipe my hard drive and reinstall my OS after my MacBook Pro failed to start.  I managed to restore all my files from a Time Machine backup on an external HD after installing OS Yosemite.
    After my computer is up and running again, I switched on Time Machine again, which started deleting my older backup files to make room for a new backup.  Before I know it, it has deleted all my backup files except for the latest one, the one which I used to restore my computer. 
    Then Time Machine discovered that it still would not have enough room for the new backup and stopped.  So I don't think anything new has been written to my external HD yet.  Given that Time Machine may not have overwritten the old backup images (fingers-crossed), is there any possibility that I could recover those?  If so, how do I do it?
    The old data backup is extremely important for me.  Any help or advice will be greatly appreciated.  Thank you very much.

    Thanks -- I would like to try this. I do not know how to reach hard drive from old mac to new. Can you help me with this?
    There are two ways - you can boot your old Mac in Target Mode (reboot your Mac, and as soon as you hear the startup chime hold down the T key on the keyboard until you see the yellow/orange Firewire logo on screen).  You can then use a FireWire cable to connect your new mac to your old one.  The old Mac hard drive will appear on your new Mac as if it is an external hard drive.
    Details on Target Disk Mode:  http://support.apple.com/kb/ht1661
    If you don't have a firewire cable but you do have a home network (i.e. both computers can access the Internet at the same time), you can share the hard drive on your old Mac and then connect to it on your new Mac.
    Good article on sharing your hard drive:  http://support.apple.com/kb/HT1549
    Finally, if the above doesn't thrill you, you can hook an external drive to your old Mac, copy the mail folder over to it, then connect the external drive to your new Mac and copy it over.  It's two steps, but if you don't have a firewire cable and aren't comfortable with sharing over a network it will work just as well - you just have to wait for the mail folder to copy twice instead of once.

  • Migrating to new Mac Book Air using time machine and seems stuck?

    I am transferring my data my  5 year old Mac Book Pro to new Mac Book Air via Time Machine because other methods were not working due to technology out of date incompatibility and my old computer is on its last legs here.  Need to get moving on this. Everything appears to be going fine. Just wondered since I have never done this and I realize it takes awhile. At present, the screen is saying it is transferring documents and will take another 13 minutes and it has said this for the last 2 hours and the line below shows still about 2/3 more to go.  This has been going for about 4 hours total now. Just wondering if this is normal?
    Thank you in advance.

    It takes awhile, especially if you have a lot of data. The last time I did this it took over 6 hours. The time estimates are usually way off.

  • Just moved CS4 Web from old mac to new using time machine. Apps won't launch. Help?

    Just moved CS4 Web from old mac to new using time machine. I get an error when I try to launch a program on the new computer (150:30). After contacting live chat about the issue and providing all serial numbers etc. I was directed to a download. The download was a .dmg file that my computer did not recognize. It was suggested that I ask the experts on the forum how to resolve the issue. I have all the discs and serial numbers but the new macbook pro doesn't take discs (I guess they think all apps are downloadable now). Any ideas?

    Hmm... I don't know why they sent you here... CS4 is not part of the Cloud
    I have some download links for earlier versions of Premiere Pro and Premiere Elements, but not CS4 Web
    My best idea is to take a LARGE USB memory stick to a friend with a DVD drive and copy your DVD over to the USB memory stick
    Or, ask in the forum for your program(s) to find out if anyone has CS4 download links

    It's confirmed, H.e.l.l. has finally frozen over!  TM drives are now bootable!
    Still it's not a real bootable clone, can't run the computer off the external drive for long in only Recovery mode, still requires the boot drive to be replaced if it not functional, and with TM backing up every hour, isn't going to offer much software protection as the TM drive is just as likely to be as messed up as the internal boot drive.
    For a iMac it still requires the computer to be taken in to Apple for a drive replacement, as ONLY Apple can do it due to proprietary connections and firmware on the iMac hard drives.
    But it is bootable!
    The backup time factor can be controlled using TimeMachine Editor, from every hour to just when the user thinks it's necessary.
    Apple lurches slightly forward!  Hurray!
    Question is, can one restore from earlier stable TM's or just the last one? In this bootable fashion?

  • How do I use a Mac Mini + Airport Express + Time Machine disk to backup another iMac

    How do I use a Mac Mini + Airport Express + Time Machine disk to backup another iMac?
    The question pretty much says it all.
    I have a Mac Mini with an attached 3TB Hard Drive used for Time Machine Backups.
    I have an Airport Extreme base station which services that machine plus several others.
    I would like to backup my new iMac and a MacBook Pro to the Mac Mini.
    What do I need to do on the mini to export that hard drive so that it can be used as a Time Machine target from the other systems?
    All systems are running 10.6.8.

    Well you would have to do backups over a network which is much slower and has highest chance of becoming corrupt. I think your best option would be to get an apple time capsule to act as a network and back if thats how you wanna do that

  • How to share more than one Time Machine folder

    Hi,
    With Snow Leo Server I found how to find how to share more than one Time Machine Folder but I can't see how to do the same with Lion Server, could you help me with that ?
    The goal of that is to offer one TM folder per user which is located on a dedicated partition in order to limit the size of TM backups per user (150Gig).
    In Lion, in can only share one TM folder for everybody and I didn'tfind if I can set a limit size per user...
    Thank you in advance,

    I have figured out a way to enable multiple backup targets.
    However, it's one of these things I wouldn't want to describe to anyone except true programmer types, because everyone else has a 90%+ chance of messing up their system if they do something wrong.
    It involves turning off file sharing, and then editing the plist files in /private/var/db/dslocal/nodes/Default/sharepoints/
    The gist of it is this:
    a) first create all the share points you later want to use for TimeMachine, and set them up for afp-only file sharing, also create one TM target, which you can either use later, or have there so the system has one entry it knows how to handle. I just made a bogus one that I'm not actively using.
    b) turn off file sharing in Server.app
    c) turn off TimeMachine in Server.app
    d) now you can edit the files, the easiest is with Xcode, so you may want to install that first
    e) for each sharpoint you made in a) there will be a corresponding .plist file in the location indicated, these are the files that need to be edited.
    f) for each of these files
         1) the item0 string property in the timeMachineBackup array must be switched from 0 to 1
         2) a new key of type array with the name timeMachineBackupUUID must be created
         3) in the newly created array an item of type string must be placed with the value of a UUID, which can be created with the shell command uuidgen
    g) make sure all the edited plist files are saved
    h) turn on TimeMachine in the Server.app again
    If all went well, you now should be able to go to one of your networked client computers and see all the time machine share points just created as options for being a time machine target.
    Anyway, if you go that route: be careful, don't blame me if you muck things up...

    Photoshop's licensing information might have lost when you restored it to new HD. Re-install Photoshop CS4 and enter the same serial key for PS CS4 which you used before.
    In case you need the download link for PS CS4, you can get it from here. Download CS4 products
    Let me know in case you still get any issues.
