Can Time Machine back up a failed hard drive, and how long will it take to prepare?

1. The hard drive in my 2009 MBP has failed. My Time Machine external drive failed about three weeks ago, and I don't know if I'll be able to restore from it. Is it ever possible to backup a failed hard drive with Time Machine? The machine boots, it just comes up beach balls if I use any applications for very long.
2. I'm trying to back it up right now. I have Time Machine running to a new external drive. It has been stuck on "preparing backup" for about 20 minutes. Everyone says that preparing a first backup takes some time, but no one says if "some time" is 15 minutes or one hour or more. What is a typical length of time for preparing first backup? At what point should I walk away?
If it's not worth trying to back this drive up myself anymore, I'd love to just drop the thing off and get the hard drive replaced -- but if it's worth doing, I'll take the extra day to back up what I can.

You might have better luck using a clone.

Can 'Time Machine' back-up other external hard drives

Can 'Time Machine' back-up other external hard drives connected to your mac as well as the mac memory itself?

As Neil says, yes, it can. But external HDs are excluded by default; you have to tell Time Machine when you do want to back one up.
See the exclusions box in Time Machine Prefs > Options.
If the drive is shown in black, just select it and click the minus sign at the bottom.
If it's shown in gray, though, it's not formatted for a Mac, and Time Machine can't back it up (and you can't remove it).

Can Time Machine back up a external hard drive connected to Airport Extreme

I recently purchased a new macbook pro, and airport extreme.
I attached a 750 GB external hard drive to the macbook pro, and reformatted it so time machine made the initial back up and hourly back ups from there.
Is it possible to now to unattach the external hard drive and attach it to the airport extreme, where the mac book time machine will back up to the external hard drive through airport extreme?
i have seen conflicting posts is if this is possible.

That would probably be safest.
Note that Apple's position on this got even more negative with Snow Leopard: http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html
It does work well for some folks, not so well for some, and not at all for others.
I got a refurb dual-band model in September. It worked well for about 3 months, but lately I get the error 109 and corrupted backups every few days, that Disk Utility can't fix. Once, Disk Warrior could, but since then, if they're corrupted, nothing helps. That's on a year-old Seagate drive that seems fine otherwise, especially when connected directly.
And I have an excellent wireless connection; it's only about 10 feet from my Mac, speeds are great, S/N ratio is good, etc.
It makes no sense to me that a TC would work better, but they seem to.

Can Time Machine back up an external hard drive plugged into a Time Capsule

I have iTunes and iPhoto libraries that have outgrown the hard drive on my laptop so I've moved them on to an external hard drive. Since I'd like to move around the house with the laptop, I've plugged the external hard drive in to the Time Capsule so that the files on the external hard drive will be accessible on the network. Now that my really important files live on an external hard drive, I want to back it up.
Time Machine is backing up my laptop's internal hard drive to the Time Capsule drive, but I can't seem to figure out how to make Time Machine also back up the external hard drive that's plugged in to the Time Capsule.
Is this possible?

I understand that [Chronosync|http://www.econtechnologies.com/pages/cs/chrono_overview.html] ($40 U.S.) can do that, but I've never used it.
If you do that, you'll want to back it up to a disk image on the TC's internal HD, or a separate HD. See #Q3 in [Using Time Machine with a Time Capsule|http://web.me.com/pondini/TimeMachine/TimeCapsule.html] (or use the link in *User Tips* at the top of this forum) for details.

Can Time Machine back on one external hard drive (work files) to another external hard drive (back up)?

Can Time Machine on a Mac Book Pro 10.5.8 back up an external hard drive (working files) to another external hard drive (WD dual backup)?

I have Mountain Lion here ready to upgrade, but I'm scared of what will happen - there's always something when you upgrade, but I guess that's for a different post!
Yes, it's a different post, but let's make a comment any way.
Your power pc apps will not work when you upgrade to Mountain Lion. You will have to replace all the apps you use.

Can time capsule back up an external hard drive attached to my imac and the iMac internal Harddrive

In addition to Kappy's comments, the external drive must be formatted in Mac OS Extended (Journaled) in order for Time Machine to be able to back it up.

HT204057 Time machine back up via USB hard drive connected to Airport Extreme.

Why did Apple stop supporting time machine back-up via USB hard drive connected to Airport Extreme? It worked very well.

Why did Apple stop supporting time machine back-up via USB hard drive connected to Airport Extreme?
Time Machine backups are supported via USB hard drive connected to the AirPort Extreme"ac" version.
Time Machine backups were not supported via USB hard drive connected to earlier versions of the AirPort Extreme.
Some users who tried this on earlier version AirPort Extremes seemed to have some success with Time Machine backups....some had moderate success and some had no success with this. Count me in the "no success" category.

Time Machine "Backing up to multiple hard drives"

I had problems when switching between two external hard drives using Time Machine.
Upon speaking to Apple Tech Support I learned that when getting an error code that prevents me from using one of my hard drives, that there is a work around. Seems that when using two hard drives at different times an issue may be encountered. The solution involves using Terminal in Utilities and typing in code from Apple plus the error number on your computer. I'm no expert so won't try to go step by step but the solution worked in Terminal and the code started with sudo chown `id -un` "/Volumes/Time Machine Backups/.0016cbd00dc9"
Disregard the numbers after Time Machine Backups since that is my own error code.
After entering the 'sudo, etc...' it will ask for your computer password.
Then, in Terminal type in sudo chmod 400 "/Volumes/Time Machine Backups/.0016cbd00dc9" and the return key again, and again your computer password.
That all helped solve a problem that even Disk Utility with the Installation Disk didn't help. The problem arises when trying to back up Time Machine between 2 different external hard drives.
Hope this helps some of you...

This will keep TM from objecting to the new drive, but you need to be sure the right things are getting backed-up to both drives. This has been discussed here before, and never confirmed, as far as I know. You can be a big help to us by confirming whether this actually works.
Do this please, both for us and so you're confident that both drives contain complete backups:
Download the TimeTracker app, from www.charlessoft.com.
It shows most of the files saved by TM for each backup (excluding some hidden/system files, etc.).
1. Turn TM off temporarily (so it doesn't interfere by doing a backup).
2. Perform backups to both drives.
3. Add a small test file to your home folder.
4. Do a +Back Up Now+ to the first drive.
5. Using +Time Tracker,+ confirm that the test file was backed-up to the first drive.
6. Do a +Back Up Now+ to the second drive.
7. Using +Time Tracker,+ see if the test file was backed-up to the second drive.
Post the results here. If it actually works (the file gets backed-up to both drives), we'll put this into step-by-step instructions for others who want to do this.

Restoring time machine back up to new hard drive

Today, I went to a computer store and had the hard drive replaced on my Macbook Pro 2008 model. I was running snow leopard, but with the update the guy updated my OS to Mavericks, he hasn't put anything else on the computer though.
What I want to do is restore back up from time machine (situated on an external hard drive). However I don't want my system to glitch or revert back to Snow Leopard. I want the back up to run on Mavericks. What is the best way to run this back up?

Hey jshark1,
You can use Apple's Migration Assistant (located in /Applications/Utilities) to bring your data to your new system hard drive. See this article for an overview of how to do it -
Move your data to a new Mac - Apple Support
While the article is about transferring the information from another computer, it also allows you to do so from a Time Machine backup. Start from the sections labeled Choose a connection method.
Thanks for using Apple Support Communities.
Be well,
Brett L

I just got one of the new iMac. following the on screen instructions to do migration assist. I guess it connected via wifi to my old iMac. now it seems to have stopped. what can I do to not mess it all up? how long will it take on wifi?

I just got a new iMac. was following the onscreen instructions to do migration assistance and I guess it connected to my old iMac via wi fi. It never instructed me to connect via firewire. Now it seems to have stopped. what can I do that won't completely mess it up? how Long will it take to do over wi fi?

Your new iMac does not have a Firewire port so you ned this adapter:

How to Copy a Specific Time Machine Back-Up to Ext Hard Drive

I'm transitioning from a MBP early 09 to a MBA mid 11. I pruned the MBP pretty well to migrate items from it to the Air, but I want to preserve the last "full" Time Machine back-up of the MBP to an external hard-drive. Not the "latest" - as the lastest back-up includes the pruning need to migrate necessary items from the Pro to the Air - but one dated a few days before I began the pruning. How do I get that specific back-up (currently on External Hard Drive A - 250 GB) onto a new external hard drive (Ext Hard Drive B - 1TB)? I want to preserve that specific back up then ERASE Ext Hard Drive A to use as a portable for the the MBA. Thank you.

don't delete anything on the TM drive using finder. you can do it from TM interface. however, in your case it will not help because TM will always make a full backup after a system restore like you did and there is absolutely no way to avoid it. as suggested you might want to reformat the TM drive and start backups from scratch.
BTW, to delete a single backup you start TM, scroll back to that backup, click on the "gears" action button in Finder's toolbar and select "delete backup".

Can I set Time Machine to backup both my hard drive and an external hard drive?

Hi. I've been working with a lot of family video lately and my internal hard drive has filled up significantly. iMovie doesn't seem to have a good archiving facility like Adobe InDesign which I use at work were all the relevant files are gathered together into one folder. Apple advised me to relocate my movie files to an external hard drive and herein lies my query.
Is there a way for me to set Time Machine to backup both my iMac's internal drive and the external hard drive that would contain my movie files? I've been using Time Machine for my backups for a few years now, but backing up the external as well has me stumped. If Time Machine could be used then all the necessary file accociations etc would be safely backed up as well - that's why I don't want to have to manually backup the external.
Anyone have any ideas? Thanks!

Thanks so much Pondini!! You just quickly answered a question that none of the Mac people in 3 stores or Apple Care have been able to answer.If you can format it HFS+ (any variation of Mac OS Extended), it will work. If not, it won't.
I'm not too surprised about the Apple Stores, as they don't get much training on Time Machine. But AppleCare sure ought to know.
Oh...what about if the external drive is an array...like a Drobo with it's own proprietary formatting...I guess that would not work...??
I've never used a Drobo. A number of folks here have used them as their Time Machine drives, but I don't recall seeing anyone try to back one up with TM, so can't say for sure. But if you can format it as HFS+ (any variation of Mac OS Extended), it will work. If not, it won't.
At least part of the reason is, Time Machine uses the File System Event Store, a hidden log of changes that OSX keeps on each Mac-formatted disk/partition, to figure out what's changed and needs to be backed-up. See How Time Machine works its Magic for details.
See Time Machine - Frequently Asked Question #32 for details and considerations of backing-up multiple volumes with Time Machine.
However, even if it will work, that may not be your best strategy, depending on your circumstances:
Since Time Machine keeps copies of things you've changed or deleted, the destination needs to be considerably larger than the data being backed-up. How much larger varies widely depending on how you use your Mac, but a general "rule of thumb" is, it needs at least twice the space to be able to keep a reasonable "depth" of backups for you.
If you have a large internal HD, fairly full, plus a large external HD, and the files on the external don't change frequently, you might want to use Time Machine for the internal, and a different app to a different disk or partition, on a different schedule, for the external. Especially if space is a consideration, you might not need to keep previous versions of files on the externals. See Time Machine - Frequently Asked Question #27 for some alternatives.

Time Machine Back Up of Damaged Hard Drive

Hi everyone. I've searched through the forums for this, but I have not found an answer specific to my problem (at least that I could find).
Is it possible to perform a Time Machine back up of my damaged internal hard drive to my Time Capsule, but using a bootable external hard drive with Mountain Lion installed?
The issue is that I cannot start up my Macbook Pro (2011) itself. It gets stuck on the grey screen with a progress bar at the bottom that reaches under 1/4 of the way through before the screen goes black and the computer shuts down (silently, without the typical electronic *beep* when it is forcibly shut down).
I booted up from my external hard drive and ran Disk Utility. When I tried to repair the disk it gave the following message:
"Error: Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files."
Although I have a recent back up, it doesn't contain the very latest work I have done and so if at possible, I would like to perform a back up if at all possible, before erasing and restoring.
(I assume booting up from the Time Capsule itself is not possilbe? And even if it were, could a back up be performed?)

Try cloning it to your Time Capsule/external hard drive.
