Time Machine Backup: Can I read a backup from a different Mac?

I have two macs. One is a Macbook Pro, recently Time Machine Backuped, out for service. The other is a G4 iMac running Tiger. Can I read files from the back-up from my macbook pro? I can search the folders.... but do not actually see the files. So, I think I could be either looking in the wrong place or my old iMac is just not able to see them.
If I upgrade my G4 iMac to 10.5.6.... will I be able to see all files on the other computer's backup?
In other words... if you have two macs that have time machine.... will I be able to view the other macs' back-up and use files?

Sorry, I missed the other Mac being on Tiger. Pullman is right -- TM's backups may look to us mere mortals like ordinary files and folders, but they most certainly aren't. Apple had to make some changes to the basic OSX file system to make TM's magic work, so I'd expect Tiger to be completely confuzzled by it.
And yes, once updated to Leopard, one Mac can look at (and restore from) another Mac's backups.

Access Time Machine Backup from a different computer

Hi everyone,
I have recently had to put my Macbook in for repair and have been told it will be about a month before I get it back. My wife has a Macbook of her own, so I using that for the time being to continue working on my MA essays due in the next two weeks. My problem is that I dutifully did a complete backup of my files through Time Machine before sending my own Macbook away, only to find I cannot access the files on my wife's computer!
I realise this is completely my fault, but the files in the Time Machine backup represent months of work and I desperately need access to them! I have tried accessing the backups via Time Machine, and when this failed I went through Finder to the Backup folder on my external hard drive, only to find a little no entry sign next to the relevant folders. When I try to open them I get told I 'do not have sufficient access privileges'. Is there ANY way around this? I am desperate!

You should post this with something to do with "Access privileges" in the title so the right people read it - those who don't use Time Machine probably won't bother with this thread. You were right to try a direct-access route through the Finder, because you can drag Time Machine files directly when you need to. I don't know enough about permissions to help you with the permission thing; it might be as simple as setting up an account on your wife's machine that has the same username and password as your own machine.
But note (in regard to the Jeremy's post) that if you do get a new logic board - yes, he's right, you'll have a different MAC address, which means you can't continue on with your TM backups. But you can't change the MAC address on the logic board; instead, there's a nice, geeky way to change the Time Machine backups record of what MAC address they were married to. You'll find the info here:

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?

Backup management: how to update a Time Machine backup on a different Mac?

Hello everyone,
I need some advice. I have a question, which I think is simple, but my situation is a bit complicated, so I am not sure about what to do.
I will try to describe it as simply as possible.
There are 3 macs:
A: an old macbook (the white one)
B: a modern macbook pro (retina)
C: another modern macbook pro (TBD)
I am giving away B now; I expect to get C in 2 months time; I keep A with me all the time.
The goal is to migrate all of the data from B to C.
I have Time Machine backups of B.
Since the transition is a long time (2 months), I need to keep working on my data during this period. For this I will use A. This will generate new files, modify old ones, ...
Since A's HDD is much smaller than B's backup, I can move only part of them.
By the way, I have totally erased A and used migration assistant to restore part of my old data from B. So, when I use A now, I do it with my same account as in B (and the same I will use in C).
How do I manage my backups in such a way that, when I will get C, I can safely move all of the data I had in B plus all of the changes and modifications that I have done during the 2 month transition?
Can I just continue to use Time Machine (on A) to update the old backups? I am afraid that some mess could be created because the computers are different (before the backups were taken on B, while now on A), even the present data are different (because now A only contains a subset of the original B data, which I do NOT want to lose), the good point is that the user is the same.
Thanks for the patience to read through. If something is not clear I will be happy to explain better.

When you get MBP C and start it up for the first time you will be given the option to transfer data or not. You can transfer data from another Mac or from a backup such as Time Machine. The former requires that you be able to connect the two computers directly together either by Ethernet cable or by having both connected to a local Ethernet network. You can use wireless, but it's very slow compared to Ethernet, so I don't recommend wireless.
If you expect to perform the transfer from a Time Machine backup, then be sure to perform a backup of MBP B just before using it to transfer data to the new MBP C.
This same process can be used from MB A provided it is running Snow Leopard or later.
Also, see Pondini's Time Machine FAQ for help with all things Time Machine.

Open time machine backup from a different computer

I just got a new MBA and want to restore some apps from my MB pro that has a larger disk drive than my new one.
So I don't want to restore everything as it will not fit on the new computer.
Can I restore some of my apps and folders from a previous MBP backup ?

You can do that through Migration Assistant (in /Applications/Utilities) > http://pondini.org/OSX/MigrateLion.html It lets you choose which apps and folders you want to restore.
Another way would be to restore your files from the MacBook Pro backup manually. To do it, you need these steps > http://pondini.org/TM/E3.html

How can I use the Time Machine Backups from my Old Computer?

I have two months of Time Machine backups made using my old Macintosh computer which died and I no longer have. I have now purchased a new computer and am trying to use the Time Machine back ups from the original computer, but it will not recognise them. How can I get my new MacBook Pro to use the Time Machine Backups from my old Computer? I phoned the Apple help line and they said I cannot use them and would have to delete them. This sounds crazy if you can only use the Time Machine back up file with one computer and have to delete it when you buy a new Mac. Surely there must be some way to transfer ownership (not files) from an old to the new Mac?
Thanks
Richard

Thanks Kevin for the suggestion posted on MacOSXHints how to "Repair Time Machine after logic board changes".
http://www.macosxhints.com/article.php?story=20080128003716101
It seems as though I am not alone with my frustration with the way Time Machine uses the MAC address of a computer to tell one system from another. This means that if you have your Mac repaired with a new logic board, or replace your system with a new one, you can't resume backups where you left off. Reading through the readers who used the fix using Terminal, it appears that the fix does not always work. I contacted Apple again, but they were no help. Surely Apple should come out with a solution as more and more people use Time Machine/Time Capsule.
It is CRAZY that after a change computers or a switch in the computer logic board that you cannot resume your Time Machine back ups.

How can I "Put Back" a time machine backup from the trash to my external hard drive?

Basically what happened was I accidentally put an older time machine backup from my external hard drive into the trash on my macbook. Since then, time machine has made new backups onto my external hard drive. How can I either "Put Back" or replace the deleted backup back into my hard drive?
Whenever I try to move it it says "A newer item named “Backups.backupdb” already exists in this location. Do you want to replace it with the older one you’re moving?" I click replace and after a few minutes of loading, it says "Cannot replace. An item named "" already exists."

As long as you don't delete the trash, the files should be recoverable.
I suspect using the Put Back command could take a long time, so be patient.
If your Time Machine backups are mixed with your daughter's backups you might want to buy a larger drive and move the Time Machine files to the new drive.
Regarding missing photos in iPhoto...There might be options to rebuild/recover that data from iPhoto rather than trying to revert to a Time Machine backup.
Check out this third party app, iPhoto Library Manager. It has a demo.

Options for a larger drive.
I like the Seagate USB 3.0 Backup plus drives. Works on USB 2.0 ports. They come formatted for PC but easy to format in Disk Utility.
I don't recommend Western Digital because of the boot problem with some of their drives.
LaCie makes good drives.
All Mac formatted drives will cost more and it’s easy to reformat with Disk Utility. Do not use the software that comes with the drives. It’s recommended that you use Apple’s Disk Utility.
Prices vary but this gives you an idea of what you’ll find. As you notice the second and third TB is usually only $15 more per TB. Normally, you’ll find these prices but right now the 1T is more than the 2T
Seagate Backup Plus 1 TB USB 3.0 $85
Seagate Backup Plus 2 TB USB 3.0 $99
Seagate Backup Plus 3 TB USB 3.0 $115
I have seen the 3T on sale for $99.
Locally, Best Buy seems to have the best prices.

OSX treats the reformatted drive as a different one; it's the same as replacing it, and the old one is no longer connected.

Can Time Machine Backup to Two Different Drives?

I have many Apple Computers, and I was wondering if it were possible to have time machine backup to two different drives.
I want it to back up My documents, Mail, and other files/folders that I access often to a partition of my internal drive every minute.
And
I want it to back up Everything on my Mac to my external each night upon connecting it to my mac.
I take my MacBook everywhere with me and I need to make sure that the files I work on the most stay Perfectly Accessible no matter what, and I don't want to sacrifice too much space for that procedure. I would rather just be able to do constant backups of my most used files and folders, and then do a system backup each night to make sure I always have what is needed.

Let me add some more observations. I use two disks, one at home (its a mounted volume on another Mac at home) and the other is a portable disk that I attach to my MBP at work. This works fine.
About your details - TM backs up every hour. If you look around you'll find some posts that give instructions on changing the frequency (I haven't paid attention to these, so I can't help you). However, backing up to another partition on the same drive is not what I'd recommend. If the drive dies, you may lose both partitions.
As for doing constant backups of the most used files and at night doing a system backup - it seems to me you aren't "getting" TM. This sounds like the type of backup strategy one uses with "regular" backup software. I don't think I'd recommend backups every minute, but for short intervals, why not just do a default backup of everything. It doesn't really back up everything, just things that have changed. The only time it does a complete backup is the first time you use it with a specific drive. After that it no longer does complete backups, unless you reformat the drive and start from scratch.

I am tring to installe OS X Mavericks. When I get to the select disk page it says that the HD is uesd as time machine drive. How can I remove time machine backup from my Mac.

Open up your Finder and click on Go on the top menu bar. Select Computer and then double click Macintosh HD. In here delete the backup folder. Might be called backups.backupdb.

HT201250 Can I copy a time machine backup from one mac to another?

I have two Mac Book Pros that I use for work - I have one at home and one at work. I'd like to copy the contents and setup from my work Mac to my home Mac using a time machine backup, and then continue to use the time machine backup back at work. I.e. the time machine would only be used with the home Mac to copy over the contents and setup of my work Mac.
Can I just do a straight time machine back up in my 2nd (home) mac, or will this override the back up I have from the 1st (work) machine?
Thanks!

Welcome to Apple Support Communities
Of course. Note that you can restore a Time Machine backup on all the Macs you want, always that the Mac uses the same or a newer OS X version than the one that had the Mac you used to make this backup.
Also, you can back up different computers to the same Time Machine drive. In this case, Time Machine will create different folders in your Time Machine drive for each computer, so one Mac backup won't conflict with the other computer backup.
To restore a backup, use Migration Assistant. Just connect the Time Machine drive, open Migration Assistant (it's in /Applications/Utilities) and follow the steps to restore the backup onto the computer

I threw out 24 time machine backups from an external hard drive into my desktop trash and now I can't empty my trash.

I threw out 24 time machine backups from an external hard drive into my IMac desktop trash and now I can't empty my trash.

Since you didn't mention what type of error message you were seeing, I'm going to guess on what is happening.
I'm guessing that since you threw away Time Machine backups, that Time Machine is probably active on your Mac. There is a chance then that the files you tossed are marked as in use. You can't delete files that are in use.
Try turning Time Machine off, then restart your Mac. Then try deleting them again.
Once done, turn Time Machine back on.

Can I restore time machine backup from Panther 10.3.9 to Lion 10.7?

Hi,
I would like to upgrade my old mac running Panther 10.3.9 to a new Mac running Lion before it fails on me.
Can I simply restore a Time Machine backup from Panther to Lion? Will my applications come across and function normally?
Let me know if you need any specific names of apps.

No your applications will not run on an Intel Mac running Lion. Macs running Panther 10.3.9 were PPC processors. Lion has no support for these old Applications Leopard and Snow Leopard supported some old PPC Applications using Rosetta

Can I recover time machine backups from the trash? They are not deleted.

I deleted by mistake time machine backups from an external hard disk and I do not know how to recover htem. The bin has not been emptied. I learnt it would be possible via "Terminal" but I do not know how. Some help would be very much appreciated! Thanks in advance.

That's not possible, the message is: backups cannot be moved (I'm workin in German). After having googled I read somewhere that it would be possible to recover the backups with the software Terminal. I copied the path of that article and adapted it - however nothing happened. So I certainly did something wrong - but what???? Do you have any idea about this? I'm a bit desperate.

I just restored my 13" MBP i5 at the apple store to the newest version of Lion after issues with a previous Time Machine backup from Snow Leopard- this time I created a new account and just ported files and folders, and now MS Office doesn't work. Help?

I just restored my 13" MBP i5 at the apple store to the newest version of Lion after issues with a previous Time Machine backup from Snow Leopard- this time I created a new account and just ported files and folders, and now MS Office doesn't work.
^^ that's the main problem. Here's the full history.
I bought a new 13" i5 MBP, early 2011 edition. I had an old white Macbook 2.14 ghz core2duo on Snow Leopard. I attempted to port over my time machine backup, but encountered problems in that my User was inaccessible from the new computer after the import finished, and I had to go in and change the root password, etc, and for some reason or another, I couldn't install any programs at all from that administrator's account. By "couldn't" I mean I could install them, but upon installation they would never boot. So, I took it to the apple store and did a clean install from the most up to date Lion OSX. Then, I created a brand new admin account, instead of trying to import the old one, and things seemed great. Then, I just imported my old files from the TM backup, but not any system settings, permissions, or user data. Just my Docs, pics, vids, apps, and itunes stuff.
Here's where things get weird again. I imported this stuff under the name "old", but all of these folders have a red negative sign on them, marking them as restricted. So, from my main admin account, I cannot even peruse these folders. Since I didn't import user data, I can't sign in to the "old" account to change permissions. I already tried to change the permissions from system preferences, but that didn't change anything. And now, for whatever reason, of all the apps that were imported then, MS Office is the only set of apps that does not work. When I click on it, it just says there was a problem and asks if I'd like to send a report to apple. I tried reinstalling it to no avail. I'm an English student, so i really need access to Word. Can anyone help? The Apple store is a major detour for me and would like to fix this issue myself.

Most likely you have Office 2004 which are PPC-only applications and will not work in Lion. Upgrade to Office 2011. Other alternatives are:
Apple's iWork suite (Pages, Numbers, and Keynote.)
Open Office (Office 2007-like suite compatible with OS X.)
NeoOffice (similar to Open Office.)
LibreOffice (a new direction for the Open Office suite.)
