Time Machine backup of external hard disk

Since it is possible to use my iTunes Library on an external hard disk I wonder if it is possible to include this iTunes Library (on an external drive) into my TimeMachine backup!

Have a read here http://web.me.com/pondini/Time_Machine/2.html

Does Time Machine backup other external hard drives?

I am using a Seagate 500 GB to backup my data. Will Time Machine backup another external hard drive on which I store my iMovie projects? If so, how do I access them in the Time Machine mode? Thanks in advance.

strange, my external HDs were added to the exception list automatically. maybe because they wouldn't fit on the time machine volume.
It seems to depend on when the drives were connected. When you first turn Time Machine on, it only excludes the TM drive itself, and any drives not formatted HFS+.
If you connect a drive later on, that drive will be excluded automatically.

Time Machine not recognizing external hard disk

I am trying to set up backups via Time Machine on my external hard drive but as I go through the process the my hard drive is not recognized in the dropdown menu. It the external hard drive is recognized in the Finder but not by Time Machine. What gives?

do you know how the disk is formatted? it may be in a format that time machine does not support, but which the finder can see. just like this guy:

Time Machine Backup of external hard drive connected to IMAC

I have an external hard drive connected to my IMAC. I also have a 2TB Time Capsule connected to my network. I store all of my video (both events and projects from imovie) to the external hard drive to save space on the IMAC. Does the Time Capsule backup this external hard drive? When I open Time Machine I don't see where the external hard drive is backed up? The drive is formatted MAC OS extended (journaled).

nujac,
Time Machine backs up all locally attached drives unless you specifically exclude them in System Prefenences > Time Machine > Options.. icon.
You should be able to see this in Finder, enter TM and highlight the external drive. Click back to a prior date. Sometimes it takes a little while to fully populate the display since it's reading across the network, give it a few minutes.

Time machine backup for external hard drive

Recently purchased an external hard drive to clear up space on my iMac, to store photos and videos. Have been using Time Machine on Time Capsule to back up iMac. Have found that Time Machine backups hang up when it appears to be backing up the external hard drive. What do I need to do to get Time Machine to back up external drive as well as iMac? FWIW, I am also backing up a second iMac to the same Time Capsule.

Can you verify that....
1) External drive has been formatted in Mac OS Extended (Journaled)
2) The external drive has not been "excluded" from backups in Time Machine Options

Time Machine backup on external hard drive

Dear Mac users
Some time ago I recieved a 2TB Western Digital My Passport hard drive. I split the hard drive (1.6TB/0.4TB) with Disc Utilities and called the 0.4TB part "TM-BACKUP". I then set Time Machine to use this external hard drive as backup hard drive. But yesterday I checked how much space I had available in my internal hard drive, I then discovered that Time Machine had also saved a backup on my internal hard drive. On one of the pictures I have added you can see the 111.81GB backup on my internal hard drive named "Sik.Kopier". The other is a picture of Time Machine where you can see that the chosen hard drive is my external 400GB hard drive.
My question is now: Where is the backup on my internal hard drive stored, and is it possible to delete that backup because I already have backups on my external 400GB hard drive.
I'm danish so please ask questions if you want something from the pictures translated.

Thank you for the answer. I have now switched off Time Machine så it ony backs up when i connects my external hard drive. But I still have the problem about the old snapshots on my internal hard drive. Now the backups/snapshots are just named "Andet = Other things" and it still takes up space. Can you tell me how i delete these backups/snapshots?

RE: Time Machine backup to external hard drive

I used my external hard drive to store important documents off of my previous Mac. None of these documents are on my new Mac. Will I lose these docs if Time Machine backs up to this external hard drive? Will Time Machine save over those docs?

As long as Time Machine doesn't need to format the drive, it won't overwrite the files. But you should preferably dedicate a drive for backup use only. Apart from anything else, you need to back up the files on the external drive you have now, and you can't back a drive up to itself.

i am using for first time the time machine and an external hard drive because I want to erase my macbook and start from zero files. Am i keeping my files in the portable hard disk when I will connect it again with the macbook or the time machine will erase all?
I would like to know if after I erase all my data, empy hard drive inside the macbook, the time machine will erase all my files that I have saved in my "WD "My passport" external hard drive

Welcome to Apple Support Communities
Time Machine has to erase the external disk in order to make backups. Before setting Time Machine up, copy the files of your external disk to the hard disk of the Mac in order not to lose them, and then, set up Time Machine. The first backup will start automatically.

Incremental backup from time capsule (time machine backup) to external disk

I have two questions regarding backing up a time capsule backup.
I would like to backup the time machine backup of my Macs from a time capsule to an external hard disk. The time capsule is a first geneneration one with 500 GB. The external hard disk has 500 GB as well with USB and firewire ports..
First question: What is the best way to connect these two hard drives - I am using a MacBook Air with two USB ports ?
Second question: What backup software could I use to do incremental backups - I tried ChronoSync but it is not picking up the changes of the sparcebundles ?
Thank you for every valuable advice
Regards

Backing-up your backups is generally not a good idea. If there's a problem with the original backup, it will be copied to, and perhaps magnified on, the copy.
You'd be much better off making "secondary" backups separately. See #27 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), for some suggestions.
About the only alternative is to "archive" the TC's contents to a USB drive connected to it, but that's not incremental, and has other downsides as well. See #Q6 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).

I use Time Machine with an external hard disc which has worked perfectly for some years. Recently Time Machine has aborted backups if the screen saver starts when back-up is in progress. I use a Maxtor OneTouch4 back-up system. Any ideas?

Has Apple recently up-dated my OS (Lion) such that every time the screen saver starts it disables Time Machine. I have to switch-off the computer and re-start in order to undertake a back-up. I have now switched of all screen savers.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode.)

How to restore a time machine backup from a corrupted disk

Hi.
I have quite a problem. I recently downgraded to os x 10.5.4 due to the requirements of Digidesign's Pro Tools. I did so with a clean install in order to have the most optimized computer possible without loads of unused data. I had backed up my data using Time Machine on an external hard-drive (LaCie, 1 TB) so I wasn't worried about losing important data.
However, when I inserted my external hard-drive after the clean installation it turns out to be corrupted in some way. It is only recognized in Disk Utility, it doesn't mount on my desktop.
Disk Utility is unable to repair the disk. The errors are:
+Verify and Repair volume “Kristoffer's back-up disk”+
+Checking Journaled HFS Plus volume.+
+Invalid node structure+
+Volume check failed.+
+Error: Filesystem verify or repair failed.+
I went out and bought "Data Rescue II" at once to try to recover my data. It works fine with the stuff I've manually dragged to the disc but the Time Machine backup folders seem compressed in some way (It's only about 86 MB). And when I click a file restored from one of the Time Machine folders it seems like it's just a shortcut to an "original file". I get this error when double-clicking such a file:
+The alias "filename" could not be opened, because the original item cannot be found.+
Is there some way for me to get Time Machine to understand the back up disk even though it's corrupted? Or some other way to retrieve my data?
I have TONS of extremely important data on the disk so it would cost me a huge amount of work to format the disk and start from scratch.
ANY help is greatly appreciated

no, that's quite impossible. you may try using Disk warrior on that drive. it's known to be able to fix the kind of error that DU is reporting. if that doesn't work your only hope is data recovery. If Data Rescue II doesn't work you can try other data recovery software like Filesalvage or try professional data recovery services (those can can a fortune).
Or some other way to retrieve my data?

How do I move data on time machine from one external hard drive to another

How do I move data on time machine from one external hard drive to another?

Although the documentation says you can copy Time Machine backups in the Finder, it's very slow and sometimes doesn't work at all.
Launch Disk Utility, open the built-in help, and search for the term "Duplicate." Follow the instructions. Turn Time Machine OFF in its preference pane while copying the volume.

I am out of space on my Macbook Air and have a Time Machine Backup. I want to complete reset my mac, but wonder if I can pick and choose what I restore to my computer? Can I also use my time machine backup and external storage as well?

I am out of space on my Macbook Air and have a Time Machine Backup. I want to complete reset my mac, but wonder if I can pick and choose what I restore to my computer? Can I also use my time machine backup as external storage as well for the files I don't need everyday?

If you are using "Restore from Time Machine Backup" option from OS X Recovery, you can only choose from the broad categories presented.
... Can I also use my time machine backup as external storage as well for the files I don't need everyday?
To be clear, if you are asking if you can use the volume containing your Time Machine backup to store additional, non-Time Machine files, the short answer is yes.
It's not a good idea though, since the Time Machine backup will eventually fill all available space, after which it begins to remove old, "expired" backups to make room for newer ones. The presence of additional files doesn't change that fact, and Time Machine will not erase them, but you will encounter a dilemma should you want to store additional files on that volume when there is no remaining space. You will have to make room for them on your own, by deleting existing files. Furthermore, since Time Machine cannot back up its own volume, those additional files will not be backed up by Time Machine.
The easy solution for what you describe is to purchase additional external storage. External USB hard disk drives have become very inexpensive; about $55 will buy a perfectly suitable 1 TB drive.
You can also choose to replace your MacBook Air's internal storage with a larger capacity one. Look for a suitable replacement from OWC / MacSales:

That gets a little more expensive but it is the optimum solution.

How do I use my Time Machine as an external hard drive to just dump files no longer needed on my computer?

How Do I use my time machine as an external hard drive?

Time Machine is software that allows a Mac to backup to a Time Capsule or other hard drive, so I think you are asking about the Time Capsule here, correct?
http://www.apple.com/timecapsule/
How do you plan to connect the Time Capsule to your network, or is it already connected and configured?
When you have it configured on the network, you can use the Finder to copy/paste or drag/drop files from your Mac to the Time Capsule disk.

HT3275 Time Machine says my external hard drive does not have enough

Time Machine says my external hard drive does not have enough space for the current backup. It needs 34 G out of a 250G hard drive. All that is on the drive is earlier backups. I recently added memory, which may confuse Time Machine into thinking it is a new computer. How can I erase old backups and complete this one?

See #C4 in Time Machine - Troubleshooting.
If that doesn't clear it up, how much data is on your Mac? If TM is only trying to back-up 34 GB, it should be able to delete old backups to do that (assuming you're running Lion).
It sounds like your backups may be corrupted. Try to repair them, per #A5 in Time Machine - Troubleshooting.
I recently added memory, which may confuse Time Machine into thinking it is a new computer.
If that's all you did, no.
How can I erase old backups and complete this one?
Just erase the drive per #1 or #2 of Using Disk Utility.
