How to restore from Time Machine onto an external drive

Hi all,
I am a backup freak, and I don't feel entirely safe with Time Machine taking care of backing up my system unless I can test every now and then that I would be able to do a full restore. I've had problems in the past with .Mac/MobileMe's Backup.app, which would not be able to restore from an otherwise apparently successful backup, for one reason or another.
So, is there a way to test a full restore from Time Machine onto an external hard drive?
Thanks for your advice

of course. connect an external, boot from the snow leopard DVD and choose "restore system from backup" from the utilities menu. follow the instructions and choose the external drive as the restore destination. make sure it's properly formatted. it should be formatted mac os extended with GUID partition scheme.
also, you might want to consider doing secondary backups in addition to TM by making a bootable clone on another external drive. use CCCloner or Superduper for such backups.
Thanks for your advice

Restore from Time Machine not recognizing External Drive

Hi all,
I woke up the other day to a black screen and a frozen macbook pro (4 months old). It wouldn't boot up past the gray screen, so I tried to repair the drive with the install disc. It said that there are no errors (liar!), so I wiped it and tried to restore from my latest Time Machine backup (should be the day prior).
However, when trying to restore through the install disks, I only see a backup from April (5 months ago). Even if I try to restore from that one, it says that I don't have enough disk space and won't do anything for me.
Migration assistant in OSX doesn't see my external drive, even though I can access it through finder.
I just want my system back to what it looked like prior to my crash. Shouldnt Time Machine have this capability?
Thank you for any help.

You should take your question to the Time Machine forum. More experts there on TM than you can ever imagine.

How to restore from Time Machine WITHOUT install discs using a second Mac

It's a question that is asked repeatedly all over the web by Mac users like me that bought in to Time Machine (TM) on the assumption that if their computer died one day it would be a piece of cake to restore from it, only for that day to come and then to be told "ahh, okay the first thing is to get your computers install discs..." (loud crashing sound of world falling around ears).
I've never been able to afford a new Mac and both of my machines were bought second-hand. Neither came with Leopard (both have Tiger and have been upgraded to Leopard via the net). This was never supposed to be a problem as I've been backing up with TM. However it appears that Tiger discs are as much use as an inflatable dart board when it comes to using TM. So I've been faced with the possibility of having to spend £130 (about two hundred Pres Sheets, Yankees) on the Leopard install discs just so that I can have the option of restoring from TM. Bonkers.
However after much nashing of teeth, a very long weekend learning all sorts of things about 'Target Mode', 'Single User Mode', 'Verbose Mode', 'Open Source 9' etc the following solution has worked without the need to go out and buy those over-priced discs...
What you will need:
1 broken Mac requiring restoration
1 second donor Mac running Leopard (or Snow Leopard so long as the broken Mac can run it)
1 firewire cable with the correct fitting at either end to attach both Macs together
1 Time Machine backup
Note: The following is for when you have given up trying to boot from your hard drive. In my case I couldn't boot in to Safe Mode etc. so was forced to format my drive and re-import everything. If you've read this far I'm assuming your at the same point as well and have tried everything else that's out there first.
Also - both my Macs are Power PC's so can't run Snow Leopard, so I can't say 100% this will work with SL (Intel) machines. From what I've read Snow Leopard will work with this procedure too, but if you've found differently please feel free to add your experiences below...
STEP ONE: Format the corrupt Hard Drive or replace with a fresh HDD
*Link the two computers with a firewire.
*If you're replacing your HDD, remove your corrupted hard drive from the 'broken' machine and insert a new one.
*Power up the broken Mac whilst holding down the 'T' key. This will start it up in Target Mode and you'll get a nice firewire symbol floating around that machine's screen.
*Power up the second 'healthy' Mac. This will be our 'donor' machine. When it starts up after a few seconds you will see the hard drive of the broken Mac appear on the donor Mac's desktop.
*Using your donor Mac's 'Disc Utility', format the broken Mac's hard drive (now's the time to partition it etc. if you want to).
STEP TWO: Clone your donor Mac
Your broken Mac is no longer broken and now needs a new OS. But you don't have the discs, right? Well get this... you can clone your donor mac on to your machine, even if they are totally different i.e. a laptop on to a tower.
*Again using Disc Utility, click on your donor Mac's hard drive. The restore tab appears as an option.
*Click on restore and drag the donor Mac's hard drive that contains the operating system in to the Source box.
*Drag the newly formatted hard drive on the broken Mac in to the Destination box.
*Click restore. Your donor Mac's hard drive will now be 'cloned' on to your no-longer-broken Mac. Once this is done, eject the first Mac's hard drive from your donor Mac's desktop. You no longer need the donor Mac.
Ta daa! Your machine now starts up happy and smily again. Time to restore all that stuff that's been sat on your Time Machine drive...
STEP 3: Restore from Time Machine using Migration Assistant
This is the really clever part that prompted me to write this piece in the first place. Time Machine IS accessible without those Leopard install discs you don't have. You need to use something called 'Migration Assistant'.
*Start up your machine as normal and you'll see it is an exact clone of the donor machine. Weird huh?
*Attach your Time Machine hard drive. It will show up as an icon on the desktop and because of it's size, you'll be asked if you want to use it as a Time Machine backup. Err, NO YOU DON'T! Click 'cancel'.
*Open Migration Assistant (if you can't find it just type it in to Finder and click). There are three options, the middle one being to restore from TM or another disc. Yup, you want that one.
*Migration Assistant will now ask you what you want to restore in stages, firstly User Accounts, then folders, Apps etc. It will even import internet settings
And that's you done. Let Migration Assistant do it's thang... altogether I had about 140gb to restore, so it wasn't exactly speedy. This wasn't helped by the fact that my TM hard drive is connected via USB (yes, I know). Just leave it alone and it'll whirr happily away...
Before I go - you don't have an option of when to restore from, and will restore from the last Time Machine save. At least then you should be able to access TM and go 'backwards' if you need to.
Also - for a Mac expert, the above will be up there with 'Spot Goes To The Farm' in terms of complexity. However, for the rest of us the above is only available in fragments all over the net. By far the most common response to 'how do I restore from Time Machine without install discs' is 'you can't'. If I'd found the above information in one place I could have saved a lot of hair pulling and swearing over the last couple of days, so forgive me for sharing this workaround with the rest of the world. Meanwhile your expertise will come in very handy for the inevitable questions that will get posted below, so please feel free to help those people that won't be sure if this solution is the right one for them. I'm no expert, I just want to help people that were stuck in the same situation (and looking at the web, there's a LOT of them).
Hope this is of use to someone, thanks and *good luck*!

Most maintenance and repair, restore and install procedures require the use
of the correct OS X install DVD; be it an original machine-specific restore/install
disc set or a later retail non-specific general install disc set.
By having an unsupported system, perhaps installed via an illegal download or
other file-sharing scheme, where no retail official discs are involved and the
initial upgrade was done by other means outside of the License Agreements,
you are asking us to discuss a matter of illegal installation and use of a product.
There are no legal complete OS X system download upgrades online; only bits
that are update segments to a retail or as-shipped machine's original OS X install.
+{Or an installation where a previous owner had correct retail upgrade discs, &+
+chose to not include them with the re-sale of the computer it was installed in.}+
However, to answer the initial question. To get and use an externally enclosed
hard drive in suitable boot-capable housing, and get a free-running Clone
Utility (download online; often a donation-ware product, runs free) you can
make a bootable backup of everything in your computer to an external HDD.
This is the way to make a complete backup to restore all functions to the computer.
The Time Machine has some limits, in that it can restore only that which it saves.
It does not make a bootable clone of your entire computer system with apps and
your files, to an external drive device. A clone can. And some of the clone utility's
settings can also backup changes to an external drive's system; if that other drive
is attached to the computer correctly.
Carbon Copy Cloner, from Bombich Software; and also SuperDuper, another of
the most known software names you can download and use to clone boot-capable
system backups of your computer's hard disk drive contents, are often cited.
However you resolve the matter of the running OS X system in your computer,
derived from what appears to be questionable means, is part of the initial issue.
Since you do need to be able to fix an existing installation by unmounting the
computer's hard disk drive and run the computer from the other (install disc or
system clone) while it is Unmounted; and use the correct Disk Utility version to
help diagnose and perhaps be able to fix it. You can't use a Tiger version Disk
Utility to fix a Leopard installation, and so on.
So, the situation and replies as far as they can go (since the matter does
constitute an illegal system, if it was arrived at without correct discs) is a
limited one. And file sharing of copied Mac OS X (and other) software is
also considered illegal.
And, one way to get odd malware and unusual stuff, is to get an unauthorized
system upgrade from an illegal source online. You never know what's inside it.
The other reply was not a personal attack; the matter is of legal status and as
you have a product with a questionable system, the answer is to correct it.
And if you want to save everything in your computer, make a clone to a suitable
externally enclosed self-powered boot capable hard disk drive. With older PPC
Macs, that would best be to one with FireWire and the Oxford-type control chips.
However that works out...
Good luck & happy computing!

How to Restore from Time Machine in Single-user mode?

Hi there, I am trying to fix a Macbook Pro that has had its /private folder trashed and emptied. Obviously it won't boot unless you you boot in to Single User mode and I'm wondering if its possible to do a Time Machine restore from the terminal, I would need the 2nd more recent Time Machine image which is sitting on a Firewire HDD.
I was going to just see if I could find the orignal OSX install disk and just do a fresh install of the OS which I don't mind doing (since everything important is backed up in Dropbox), but I can't seem to find the CD anywhere nearby, so the Time Machine option would be much preferred.
Any help would be greatly appreciated.

Not sure if this is related enough, but I just wrestled trying to restore from time machine too, trying to reinstall 10.5.8 after putting a new HD in my MBP, 2006 vintage.
That took sooooo long to get back to where I was before swapping disks; what did the trick was ordering a free copy of Snow Leopard install disk (free due to Apple trying to push people from idisk to icloud) which was rushed FedEx (yay) and which allowed me to access Time Machine where my ancient original OSX install disk had not.
And all it took was 2 weeks of cursing!

How to restore from time machine for another user login

I use time machine to back my computer which has multiple user login.
First I set up time machine backup using User A. I checked that User B files in the hard disk is also backed up, and I can restore using User B login.
Then I changed the hard disk today and all users I need to recreate again.
After recreating users, I found that User A can restore files from time machine backup.
However, files originally under User B cannot be restored using either User A and User B. The error message is
"The folder “Documents” can’t be opened because you don’t have permission to see its contents."
Anyone can help?

How to restore from time machine different OS

I am going back to snow leopard (from OS 10.8 back to 10.6) using my mac book pro (mbp). I backed up my data using time machine then loaded the orig OS from disk (leopard). This erased my HD on my mbp. I loaded the orig OS successfully (leopard). When I tried to restore data and apps from time machine, it said I could not because the time machine was backed up using 10.8 (and I needed to upgrade if I was going to restore from time machine). The point is I dont want to upgrade (I am downgrading away from 10.8 back to 10.6). Another option is restore from another mac. I have another mac (mini) running 10.6 and I transfered the time maching data from my mbp to the mac mini. Now I am trying to restore data and apps from the mini to the mpb (using a firewire). Is there any easier method??

You made a mistake: create a Time Machine backup on Mountain Lion. Doing this, you can't restore the backup on older versions, so if you want to downgrade, you will have to restore the files manually, taking so much time, and you will have to reinstall all your applications.
To transfer your files from your Mac mini to the MacBook Pro, you can use FireWire without any problem (furthermore, it's the fastest way). Connect the FireWire cable, open Migration Assistant on both computers and follow the steps

After restoring from Time Machine to new Hard drive, system will not boot

I replaced my hard drive on my Macbook (2008 model) with a larger drive. I then put in my Snow Leopard disk, and followed the steps to restore from Time Machine backup. a few hours later it said it was restored, but when trying to boot up, I just get a blue screen with an occasional flicker to the Leopard screen. I tried an earlier back up as well but with the same results. Any suggestions??

Same exact problem here just yesterday, folks.
Got a bigger hard drive on my MacBook Pro (15-inch Core 2 Duo) and installed it. Followed the restore procedures from Gizmodo (http://gizmodo.com/333319/the-secret-of-the-time-machine+assisted-hard-drive-swa p). Then got the blue screen immediately after the chimes.
I only managed to transfer my old disk content by using CarbonCopyCloner.
Having said that, your solution looks uselful, Portland Mac! :

Am I mistaken, or did you do a fresh install after restoring your TimeMachine backup?
In any case, I found an interesting Apple article that might confirm that there is a problem: [Mac OS X v10.6: Issues after restoring a Mac from a Time Machine backup made with a different Mac ("Restore System From Backup…")|http://support.apple.com/kb/TS3243]. Or is it a completely different thing?
And another discussion that might give some good advice: [http://discussions.apple.com/message.jspa?messageID=12578529#12578529]. Personally, I will now do as the man says: two backups, on two different external hard drives, using different apps, the other one being CarbonCopyCloner...
For info, and I don't know whether that matters, my backup disk had been full and some past content had been erased automatically by Time Machine. But I don't think this should have mattered...

Toasted my installation. Restoring from Time machine to 2 hard drives?

I just installed a second hard drive into my macbook pro. SSD is the system drive and HDD is the data drive.
When it was still working, I had my home folder on the SSD and my iTunes and Photo libraries on the HDD. Things were good.
Then I decided to move the entire home folder to the HDD.
Sys Prefs -> Users -> right-click the user -> advanced -> "move the home folder"
and again, everything was good.
Then I read something about having the user Library folder on the SSD is a good thing.
So I moved the home folder back to the SSD. Rebooted and all my prefs were now gone. Figured I messed up something and didn't want to troubleshoot.
So time for a restore.
Attempt 1
- Open Time Machine, select both hard drives, selected a past date and hit restore.
- Got a message that I didn't have enough space.
* I figure this is because time machine restores the entire contents of each drive as entire new volumes as a first step.
Attempt 2
- Go into recovery mode COMMAND+R
- Discovered I don't have a recovery partition
* I guess this is because I cloned my original system drive to the SSD using CCC and it didn't move this part.
Attempt 3
- I created a LION USB Install Key
- Booted from it, and selected 'Reinstall Lion' (because I read an article that I could recover my files after Lion had finished installing)
* Discovered that it reinstalled 10.7.0 and I would have to apply all patches on top. It didn't restore my HDD either.
* Later found out this method only restores the main system drive.
Attempt 4
- Now that I have a recovery partition, I booted from it.
- I selected "Restore from Time Machine Backup"
- Was able to select my Time Capsule, and it gave me choices on which date I would like to restore to.
- I selected and hit restore.
* It's about 25% done now. And I realize that i should've done this in the first place.
Question: Will this method restore both of my hard drives?

Question: Will this method restore both of my hard drives?
No, only a single OSX drive. If both were backed-up, and both contained OSX, there was a (not very obvious) option to select which one you wanted.
See Time Machine - Frequently Asked Question #14. Section (g) shows this.
If you want to restore the "other" drive, and it contains OSX, run the restore again and select it.
If the other drive doesn't contain OSX, use the "Star Wars" display to restore it, per FAQ #15.

How to reinstall from time machine onto a new hard drive?

how to reinstall the system from time machine to a new hard drive?

If you are connected to the internet you can do this.
Boot your computer and immediately hold down command, option and R (three keys together). This gets you connected with internet recovery.
See this article for more directions: http://support.apple.com/kb/HT4718.
This process installs an OS on your blank drive. You can then boot from the fresh OS installation and restore from your Time Machine back up.
Note that you cannot boot from a TM back up.

Recovery from time machine onto new disk drive

i am replacing my failed G5 internal disk drive with a new disk drive. can i recover everything (including OS) from my time machine backup or do i need to install the OS (Leopard) first and then recover from time machine?

You can boot off your 10.5 installer disc that was usable to install 10.5 on your G5 and run the restore from its Time Machine restore in the Utilities menu of the installer. Assuming the backup of course was done of the entire hard disk when you did a Time Machine backup. If it wasn't of the entire hard disk, then the restored backup won't be bootable, and you'll need to install 10.5 first.

After full restore from Time machine, my TM hard drive won;t mount

I got my macbook pro back from a logic board repair and restored it fully from Time Machine using my leopard install disc.
Took a while, but it has installed OK. But some applications weren't restored and now the Time Machine drive won't mount on the Macbook at all. When I open up time machine - and try to choose a backup disc nothing comes up.
The drive shows up on a PC when i connect it (but won;t read it as its mac formatted) so I'm pretty sure there;s nothing wrong with the drive.

Also, be aware that TM thinks you got a new Mac, not a new logic board. Thus you won't see your TM backups in the normal way. You'll need the (badly named) +*Browse Other Time Machine Disks+* option (see #E2 in the Time Machine - Troubleshooting *User Tip* at the top of this forum).
In addition, when you start doing new backups, TM will start a whole new "sequence," as if it were a different Mac. See #C8 in the Troubleshooting Tip for options.

How to restore from Time Machine when backup is larger than HDD

In an attempt to upgrade my 13 inch, 8GB 2010 MacBook Pro (750 GB HDD) from Mavericks to Yosemite, the Yosemite install was stuck at "about a minute remaining" for hours (overnight). So I cancelled the install and tried again only to be stuck at the same spot. I took the mac to an Apple Genius Bar to have it looked at while it was stuck at that install step. They couldn't fix it and did a fresh install of Yosemite. Luckily, I had backed it up about a week before, so I wasn't losing a whole lot. I attempted to restore from the Time Machine backup using Migration Assistant (2TB external USB 3.0) of the latest backup but the estimated time to restore from backup kept climbing to more than 150 hours. Eventually it had an error message that there wasn't enough free space on the HDD (the same 750 GB drive that my backups were from). There was less than 100GB of free space on the HDD before attempting the upgrade.
How can I restore at least a portion of my Time Machine backup, like my Documents and Apps? I don't even mind going back to Mavericks so that I can use my computer again! For example, I need MS Office but I cannot use it on Yosemite if I do not first get my original backup working again so that I can unregister the current version (the product key is "lost" with my inaccessible backups!).
Most of the information I can find online is how to prepare for a proper backup, but at this point since Apple Genius did a fresh install, Time Machine has my only backup!
Any advice would be great!
p.s. This may be useful to know: I had several virtual machines from Parallels: Windows, Ubuntu, etc before I upgraded to Mavericks from Snow Leopard. Mavericks required an updated Parallels that I never got but I'm sure those VMs are hiding in my backup drive.

OS X Yosemite: Restore items backed up with Time Machine
While in Time Machine, press the key combination shift-command-C. The front window will show all mounted volumes. All snapshots should now be accessible. Select the one you want and navigate to the files you want to restore.
If you need to restore from a backup of the hidden user Library folder, first select a snapshot, then press shift-command-G. A Go to Folder dialog will open. In it, you'll enter the path to the folder. The dialog will help you by automatically completing the parts of the path when you start to type them.
The path begins with slash character ("/"). Enter that. The rest of the parts will be separated by slashes.
The next part is the date and time of the current snapshot. Enter a "2", and the rest of the date should be filled in automatically. Press the right-arrow key to jump to the end of the path. Enter a slash to start the next part.
Next is the name of the volume (usually "Macintosh HD" unless you gave it a different name.) Start to type that, then jump to the end and enter a slash.
The next part is "Users", followed by a slash.
Next is your (short) user name, which is also the name of your home folder.
Finally, enter "Library", then press return. You should now be in the Library folder. From there you can get around as in the Finder.

How to restore from Time Machine?

Hello, my Macbook Pro's hard disk failed. A local service (not Apple - this is Romania) changed my hard disk to a new one, put the Snow Leopard system back and copied most of the files from my old hard disk to the new one. But not all my files are OK, some of them are damaged.
This happend in 7 december and I have a Time Machine copy from 22 of November which would be good for me.
How should I proceed - restore the whole system from Time Machie - or can I restore only parts of it (like mail, photos, etc.)?
Thanks
