Time Machine messes up with 2 Macs

I have 2 macs running 10.6.3 and I have some trouble with Time Machine. It seems the 2 computers are detected as the same by Time Machine. I use a Time Capsule for backup. When I back up 1, Under Backups.backupdb it gets the name "Justin Clifford's Mac Pro". When I back up the second computer, instead of creating a new folder under Backups.backupdb, it renames that folder "Justin Clifford's MacBook Pro" and uses it without deleting the other folders inside, as if it was the same exact computer. I already deleted com.apple.TimeMachine from /Library/Preferences on the laptop and that didn't help. Any idea what's going on?

Somehow, I managed to end up with the same UUID on both Macs. Changing them back to the way they were supposed to be fixed it.

Time Machine stopped working with new Mac address.

Greetings,
I have an IOMEGA 500, FireWire which I used to use for Time Machine. I now have a new Mac address and do not have access to the old Mac address. Is there any way that I can get the IOMEGA to start working with Time Machine? If so please give me step by steps instructions on how to make this external hard drive work again with Time Machine.
Any help is most appreciated.
Thank you for your attention to this matter.

Do you have a new Mac, or a new logic board? Either will get you a new MAC (Media Access Control) address, which Time Machine interprets as a different Mac.
Do you mean you haven't started doing backups of the new Mac, and want to view the old ones? If so, see #E2 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum).
If you want to use the old backups to set up a new Mac, see [Setting up a new Mac from an old one or its backups|http://web.me.com/pondini/AppleTips/Setup.html] (or use the link in *User Tips* at the top of this forum).
When you do your first backup, OSX should ask how you want to handle the old backups. See #B5 in Troubleshooting for details.
If that's not what you mean, please explain exactly what's going on, and what happens when you try to do whatever you're doing.

Guitar21,
your MacBook Pro has booted into its Recovery mode. From the OS X Utilities menu, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it get to the login screen now?

Do time machine back up with HD attached to mac, then change HD location?

I want to do my first time machine back up with the HD directly attached to mac (faster) then take that HD and connect it to my Airport Extreme (dual band) 802.11n router for subsequent periodic back ups (as future back ups, unlike the first one, will be far smaller, obviously).
Is that possible?
If not, what else should I do?
Ethernet directly to the router (a pain for my situation, but possible)

Welcome to Apple's discussion groups.
Is that possible?
Not without a lot of hassle. Time Machine manages backups on a locally-connected disk completely differently from how it managed backup on a network disk. It's possible to convert between the two schemes, but it's not easy.
If not, what else should I do?

I'd back up to the disk while it's connected to the AirPort Extreme, but connected via Ethernet for the first backup. It might minimize the pain if you do that overnight.

I used migration assn't to load a Time Machine backup onto a new mac. The first TM backup after that took some time, perhaps not surprising. But the backups thereafter have all taken hours, with huge amounts of "indexing" time. Time to reload TM?

Does every backup require lots of indexing? If so, the index may be damaged.
Try Repairing the backups, per #A5 in Time Machine - Troubleshooting.
If that doesn't help, see the pink box in #D2 of the same link.

Yes you can make multiple backups on one hard drive, for example if you’ve 1TB hard drive installed in your PC and you’ve two Mac Machines with 500GB drive each then you just make two backup images with size of 500GB each.

Time Machine after migration to new Mac

So, I just got a new Mac, and used the option to copy settings and files from a Time Machine volume to the new machine. Now that everything's run, though, I can't use Time Machine to backup the new Mac -- it says "Volume not found". I've Googled a bit, but most of the troubleshooting seems to assume that the drive is missing or won't mount -- the drive is there, but the Time Machine software won't use it.
What are my options here?

Hi VK
A supplementray question:
I have one i-mac happily backing up with Time Machine to an external hard drive.
I have just bought a second i-mac (stops the fighting!) and propose to use migration assistant to move my [admin] account from the old to the new i-mac leaving two other accounts on the old one. I see from your posts that it seems as if Time Machine will start a new back up series for the new i-mac's back ups. But what about the old i-mac? Will that continue to extend the existing Time Machine back up files, albeit without my transferred account and its files? If so, should I partition the external drive and start the new back ups from the new i-mac on this new partition. I'd like to end up with the old i-mac continuing to build its Time Machine back ups (less my account and its files) and have a new back up series from the new i-mac building to a separate partition on the external drive.
Does this make sense? I can't see an answer in the forum to what must be a reasonably common issue in this expandin mac world.

I have been using time machine to back up my Mac Book Pro 3.1 to my Time Capsule. Now the Time machine hangs up on "calculating time remaining".

I have been using time machine to back up my Mac Book Pro 3.1 to my Time Capsule. Now the Time machine hangs up on "calculating time remaining".
Mac Book Pro - 3.1-15-inch 2.4/2.2GHz), Processor 2.2 GHz Intel Core 2 Duo
Operating system : OS X 10.10.1
Time Machine Version 1.3, Copyright 2007-2014 Apple Inc., Modified Tuesday, September 9, 2014 at 6:03 PM
Time Capsule: 500 GB C 2007
This Time Machine software worked satisfactory until Monday Nov, 10 2014 and I have backups until that time. For several years, the software deleted the oldest back up to save the latest one. This is acceptable to me as I have off site storage that is updated every 3 months. How do I get Time machine working again?

I have spent a couple of days trying to respond to Linc Davis. Finally I figured it out . The following is a copy of data from my console from the initiation of a time machine backup until it gets stuck trying to calculate the time remaining. There is no indication that anything starts saving. I copied about 3 minutes of data. This is probably way too much data, but I do not know what is relevant.
Thanks for the help,

Migration of Time Machine backup files to new Mac

I am the proud owner of a new iMac which is replacing an old 2006 model. I have 2 external hard drives which I have now connected to the new computer, I used to back these up using TM on my old mac. Can I migrate those backup files to the new mac so that if needed I can go back to restore files from months back ? The TM backup is held on a 3rd external drive.
Looking across the web it looks like if I switch on TM it will start with new backup files and wont read the old ones. Any ideas please ? Thanks

TM will make a completely new backup of your new computer, so you may wish to use a freshly formatted drive large enough to handle TM backups (roughly double the size of the drive you are backing up.) You can use TM or Migration Assistant to transfer from an old backup. MA is only useful if you want to transfer the entire Home folder, all third-party applications and support folders, system support folders, and system preferences. But if you want to move selected files and/or folders then you would need to use the TM application.
See User Tips for Time Machine for help with TM problems. Also you can select Mac Help from the Finder's Help menu and search for "time machine" to locate articles on how to use TM. See also Mac 101- Time Machine.

HT201250 existing Time Machine backups to a new Mac

how do i migrate existing time machine backups to a new mac from my time capsule?

It took a little more research, but that link in the end solved my problem. After mounting the Time Capsule and the previous backup sparsebundle, I ran these commands to inherit the old backup (with <capsule> and <machine> representing the names of the Time Capsule and machine/hard drive respectively:
          sudo tmutil inheritbackup /Volumes/<capsule>/<machine>.sparsebundle
          sudo tmutil associatedisk -a / /Volumes/Time\ Machine\ Backups/Backups.backupdb/<machine>/2012-12-09-114511/<machine>
          sudo tmutil setdestination /Volumes/<capsule>/
"2012-12-09-114511" was the latest snapshot that was there. According to the documentation, you can pick any snapshot, since the "-a" in that command will update all of the associated snapshots.

Time Machine messed up my new internal hard drive. Help?

So I upgraded my internal hard drive to 1 TB and restored it with time machine backup. However, when I started my laptop, it kept giving me a "debugger called: <panic>" I am not sure if my time machine messed it up or it was the hard drive. Can anyone help me with this?
Also for more information, when it kept restarting and rebooting on its own, I could not control my own keyboard so I could not go to safe mode or anything like that. If you need to know more information, you can ask and I'll provide you with more information if you could help me out.
And I cannot post up the whole code cause it would disappear in 3 seconds.

Time Machine to Backup two different mac computers on a single firewire 500

I have a new generation MacBook and iMacG5 and a single Maxtor 500 GB external hard drive which has two firewire inputs. I connexted both macs by firewire to this external hard drive. I used Time Machine on both computers which are on at the same time. However I can see Time Machine works well on one mac - where I can see each hourly backup but the other mac backups don't show up. I called Tech support and was told that I cannot have both macs on at the same time accessing the same external hard drive. I see two different files for each computer's backup so why can't both computers be running Time Machine at the same time?
So...I thought I should buy the new Time Capsule 1 TB BUT I worry the same access issues will occur. How does the Time Capsule drive wirelessly operate with two macs simultaneously when I was told that Time Machine would not operate via firewire with multiple computers on a single drive.
Any suggestions...are the Tech Support folks incorrect about using Time Machine with firewire access simultaneously with two different macs?

What you cannot do is connect two computers to a single FW drive enclosure at the same time. You can connect the drive to each computer separately. Time Capsule functions as a network drive thus any machine on the network can access the shared network drive. This is not the same as using an external FW drive.
If you want to use your single FW drive to backup two computers, I suggest you first partition the drive into two equal partitions. Use one partition for the TM backup of one computer, and the other partition as the TM backup for the second computer. However, you will need to physically move the drive from one computer to the other in order to perform backups.
Alternatively, if you have a local network set up you can physically connect the drive to one computer, then set up file sharing so that the other computer can mount the shared drive and use it for backup via the Ethernet network (or wireless if it's a wireless setup.) Unfortunately, I'm not positive this will work because TM is known to have some problems backing up to network devices although it is supposed to be able to backup to network drives.
Nevertheless, you should set up two partitions on the drive for each computer in order to keep the backups separate.

Copy Time machine backup using a different Mac

A friend has a Time Machine backup from an iMac that he sold some time ago. He's concerned that the drive might fail so wants to make a copy of the backup, but doesn't have a Mac at the moment. So he'd like to use my MacBook to copy his backup drive. The backup is about 400GB, my HD is 256GB and he'd like to copy it to a new 1TB drive.
All the answers that I can find to similar questions assume that the Time Machine backup belongs to the Mac making the copy, in this case it doesn't. So is there a way to copy a Time Machine backup using a Mac that wasn't used to create the backup?

Hi ozRob,
If you would like to copy an existing Time Machine backup from one drive to another, you may find the following article helpful:

Can time machine back up if the mac goes to sleep?

I started to set up Time capsule to have time machine back up my 2 macs and realized they were both set up to go to sleep after 20 minutes of inactivity. As this is the first backup it will take some serious time so i planned to do it at night. The question is can Time Machine do the backup if a Mac goes to sleep?

The machine won't sleep if it is backing up.
If it does, just set it not to sleep for a few days.

Time Machine comes up with my Finder, not my history. How come?

If you aren't using an application that supports the Time Machine interface, Time Machine will show Finder by default (Desktop folder).
That's the screen where you can navigate through your backups to restore files. See “Restoring data from Time Machine backups” > http://support.apple.com/kb/ht1427
