Can i resume a Time Machine backup of an attached external drive (no system, just data) on a different laptop?

I am trying to find out if I can use a Time Machine (specifically on a 2013 Time Capsule) backup of an external drive (only data, no system) attached to a laptop, and then connect that same external drive to another laptop and resume the backup? Or is the Time Machine backup of an attached external drive a laptop "dependant" backup?
Additional info: The laptops in question are 15" MacBook Pro and a 17" MacBook Pro from 2011 running OSX 10.9 (Mavericks)

You are welcome.
I don't think there is a need to start a new discussion unless you want to.
You should have more than one backup of each computer. Hard drives do fail. Time Machine can alternate drives or have a Time Machine and a clone.
The concern arises because i was told that when a wireless Time Machine backup is interrupted the sparsebundle gets sort of "locked" or "damaged", and although the backups can be accessed, no further Time Machine backup is possible. One must that a brand new backup.
Apple support article. Don't let the title bother you. Look at Additional Information, which explains what happens when a backup gets interrupted. I also am including a link for troubleshooting. C3 explains what you can try if the backup is interrupted.

Can I clone and time machine backup on the same external drive?

I recently purchased a WD 2 TB external usb drive. I want to make sure that I have good backups in case my Macbook decides to give up on me. Should I clone a copy of HD or just time machine backup? Can i do both on one external hd?

Hi iVain
Fire up *Disk Utility*, click the Restore tab, then drag your old and new TM drives into the Source and Destination fields. Click Restore, and a complete copy of your old TM files will be made on the new drive. Go to TM preferences and select the new drive, and it will continue backing up just as it left off.
Hope this answers your question. See:

Time Machine Backup transfer to another external drive

Hi all,
I keep my Time Machine backups on an external HDD drive (portable USB). I have a larger drive with more space, and wanted to copy my the backup to the larger drive.
My the Time Machine backup file folder is around 750GB. When copying the Backups.backupdb file over to the new HDD the process hangs in Finder. I wonder if there a way to successfully copy it, since the Finder does not seem happy to work with such large chunks of data.
Thanks

Although Apple documentation says you can copy Time Machine backups in the Finder, it's very slow and sometimes doesn't work at all.
This technique will only work if the volume you're copying to is the same size, or larger than, the one you're copying from.
First, open the Time Machine preference pane and click the Select Disk... button. You may have to unlock the settings first by clicking the padlock icon in the lower left corner of the window. Authenticate as an administrator.
Delete the volume you're going to copy from the list of backup destinations. Then turn Time Machine OFF.
Launch Disk Utility, open the built-in help, and search for the term "Duplicate." Follow the instructions. All existing data on the destination volume will be erased. That shouldn't be a problem, because you don't want to mix backup and non-backup data on the same drive anyway.
If the volume you're copying was encrypted by Time Machine, you may have to unlock it first. Click the Unlock button in the toolbar of the Disk Utility window.
Turn Time Machine back ON and select the new volume as a backup destination. You can also continue to use the old volume, if you wish. The two will be alternated when both are available.
CAUTION: If the volume you're copying is corrupt, as shown by Repair Disk or Verify Disk in Disk Utility, then that corruption will be copied to the new drive. Don't copy data from a corrupt volume on a malfunctioning drive. Put the drive aside and don't use it until you're sure you'll no longer need the data. Then securely erase it and take it to a recycling center. Do the same if the Restore operation fails with "disk errors."

Unable to complete Time Machine backup to Iomega 1TB external drive

I've read through all the posted topics related to Time Machine failing. I've run Disk Utility without errors; ensured that the external drive is formatted correctly GUID; 1 partition; Mac OS Extended (Journaled); downloaded TimeMachineBuddy; and still cannot get my new Iomega 1TB hard drive to complete a backup. My prior external drive, a LaCie, had no such difficulties but is now full.
Here is the TimeMachineBuddy error report. I am hoping one of you can help me understand what my next steps should be and thank you, in advance:

Thanks, Pondini.
I attached a new drive last night. Time Machine prompted me that it needed reformatting, which it did internally, without going to Disk Utility. It then started a backup but hung on "cleaning up" where I found it this morning.
Again, the finder was taken out with the TM hang and I had to hard reboot (on/off button - restart doesn't work nor does force quitting finder).
Here is the sad log from last night's attempt. Since it mentions an entirely new set of failures I am now ready to point to my computer as the faulty party. $180 worth of external drives into this, I am reticent about sinking anymore money into this until I rule out the computer itself. This line "NSFileHandleOperationException:* -[NSConcreteFileHandle writeData:]: Input/output error"
seems to be the essential problem.

HT201250 How can I revert to my internal drive for time machine backups after using an external drive?

Hi. I've been using an external drive for time machine back ups and decided to revert to my internal drive, but it isn't available in the time machine options. The only available option is to set up a time capsule, which I don't own.
Is it because not enough space is available on my internal drive (approx 50GB)?
Thanks!

50 Gb free on your internal drive is relly very low and of course not enought for a any kind of backup.
How big is your internal HD ? If you have left only 50 GB free it is probably 90% full. Let's imagine you have a 500 Gb. This means 450 Gb data and 50 Gb free. How can you backup 450 into 50 ?
Second point. The backup on your internal HD is a nonsense evenif it is big enough. If it stops working you will have no bakup.
Do you have an iMac or a portable ?
The portable automatic uses the internal HD if the external is not connected, but this is intended for a short time.

Time Machine Backup iTunes Library on External Drive?

Hi, my external firewire drive that holds all of my iTunes music and videos recently crashed (it had close to 100GB). It is completely unrecoverable (tried Data Rescue II - nothing).
Would Time Machine by default backup my iTunes library if it existed on an external firewire drive (assuming, of course, that the drive is plugged in when Time Machine is working)?
If not, can this be made to happen for the future?
Thanks.

Yokenny,
To add to the former comments...
Time Machine will not "by default" backup extternal HDs attached to our Mac. You would have to go in an remove them from the TM Prefs exclusion list first, as the 'default' behavior is for TM to ADD external drives to the list.
If you do determine that your crashed hard drive was attached and backed up (you can check your TM backups via the "time travel" interface.) you may still be able to recover the backed up data. But you would need another drive named the same as the crashed drive to do it.
Let us know if this was helpful.
Cheers!

Copying time machine backup files from one external drive to another

Can anyone tell me if it is possible to copy the backups performed by Time Machine on one external drive to another external drive, and if so, how? I am using a company drive and will need to return it. It is a 500GB La Cie Drive. I just purchased a 1TB La Cie drive. A straight and simple drag & drop doesn't work. What should I do?
Thanks!!!

Time Machine backup to Seagate 3TB external drive

Hello all!
I have a 3TB Seagate external hard drive which I have already reformatted and partitioned to be my new drive for time machine. I would like to backup wirelessly through my airport extreme as if it is a time machine. I tried to set up my time machine and select my 2TB partition but the "update" button is greyed out and I am unable to get the drive to select. It only recognises the drive when it is connected via USB 3.0. Is there anyway without returning this drive and having to invest in a time machine to get the computer to connect to it over my airport extreme?? Thanks so much for your help everyone!

This may or may not have anything to do with your issue but, in my experience, Seagate full size (i.e., 3.5" HD) externals tend to run hot so they are designed to spin down when not actually in use in order to cool off. That has caused problems when directly connected to a computer so Seagate used to offer a one-time patch to turn that off. Connecting via AirPort Extreme rather than directly may aggravate the problem. I don't know if the patch is still offered for the newer drives but it might help, though not necessarily for the health of the drive.

HT3275 Why does Time Machine backup fail when an external drive is included in backup?

Time Machine will not perform a backup when I have an external drive (formatted Mac OS Extended - Journaled) included in the backup. My understanding is that it should. What am I doing wrong?
Thanks.

Ah, not one of Apple's more informative messages.
There's a problem with a file on that disk. See #C3 in Time Machine - Troubleshooting. It will show you how to locate the message(s) that describe the problem, then help you fix it.

Time Machine backups were moved from external drive to HD Trash

I've since learned that I cannot delete these from the Trash and should not have moved them there however, now what do I do? They are preventing me from Emptying anything from the Trash.

You can delete them but it may take days or weeks to complete. Backup your files.
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

Best way to transfer time machine back up files between external drives

I have to move my time machine backup files from one external drive to another. I was planning to simply move it through finder, but it has been "preparing files" for 2 days straight. The number of items sowing in the status bar with the status of "preparing to copy XYZ items" has continued to stadily grow. Is there a better route or should I let it run till it is complete?

Welcome to Apple Support Communities
That's exactly the way to transfer Time Machine backups to an external drive, so let the Finder do its job. See > http://support.apple.com/kb/HT5096
Note that the destination's external drive must be formatted in "Mac OS Extended (Journaled)"

Can I perform a Time Machine backup to a USB drive connected to the Time Capsule 3TB

I would like to perform Time Machine backups to a portable USB drive, to use as an off-site backup copy. However, when I plug the drive into the Time Capsule (3TB) it isn't seen by Time Machine from any of the computers on my network. What do I need to do to make this work?

I'm not sure about whether Time Machine can include a drive that is a month out of date in a normal rotation.
This won't be a "normal" rotation. Assuming that you have already configured Time Machine on each Mac to back up to the USB drive, when you connect the drive to the Time Capsule, you will need to manually click Backup Now on a Mac to get the backup started. Then, do the same with other Macs that you want to back up.
You could wait and see if Time Machine will start to back up on its own, but the wait would be unpredictable as far as time was concerned.
Time Machine will also spend a good deal more time in the "Preparing" stage since it will have to look a month of history on the Mac since the last backup.
It is set up and recognized in the Airport utility, and mounts normally. I can see the files using finder, but I can't get Time Machine to recognize that it is there and available for backups.
So, if you open System Preferences on a Mac,
Then, open Time Machine
Click Add or Remove Disk
The USB drive doe not appear as a potential destination?
Have you restarted both the Mac and the Time Capsule?
Any recent changes to the Mac.....like installing a new operating system?

Can i resume a Time Machine backup of an attached external drive (no system, just data) on a different laptop?
