Using Time Machine to back up one Airdisk to another Airdisk

I've got a hard drive (I'll call it HD1) attached by my AirPort Extreme Base Station (802.11n). I've been using Time Machine to back up my MacBook's internal hard drive to that drive for several months now, with no problems. I just bought an additional external hard drive (HD2) and attached it to my AEBS, along with HD1, using a USB hub. Both drives are working fine.
However, I have been unable to get Time Machine to back up HD2 to HD1. Even when HD2 is mounted on my desktop, Time Machine will not back it up - it backs up only my internal hard drive. When I connected HD2 directly to my computer by a USB cable, Time Machine will back it up to HD1. It's only when it's connected to the AEBS that Time Machine ignores it.
I would very much like to have both hard drives connected to the AEBS all the time, but I need to have my data on HD2 backed up. Has anyone been able to back up one airdisk to another using Time Machine?
Any thoughts are much appreciated.

Even if that worked, that would be horribly inefficient. The data from HD2 would be copied from the drive through the AEBS to your MacBook then back to the AEBS and to HD1.
HD2->AEBS->MacBook->AEBS->HD1

I use Time Machine to back up my entire computer with my external hard drive. I am getting a brand new iMac this month and was wondering what is the process of using this back up to restore my new computer exactly how my old computer was? I want to make sure I will still have various important files on my new computer, like my songs in iTunes, my photos in iPhoto, etc, etc. Thanks so much in advance!

Welcome to the Apple Support Communities
When you turn on the new iMac for the first time, Setup Assistant will ask you to restore a backup, so connect the external disk and follow steps to restore all your files to your new iMac. Your new Mac will have the same settings and programs as your old computer.
In other cases, I would recommend to restore the whole backup without using Migration Assistant or Setup Assistant, but a Late 2012 iMac uses a special OS X build, so the OS X version that you're using on your old Mac won't work on the new one.

I have been storing my Aperture and IMovie Libraries on an external hard drive that recently died. Fortunately I've been using Time Machine to back up to a 2nd external drive. How do I restore my libraries to a new external hard drive?

I have been storing my Aperture and IMovie Libraries on an external hard drive that recently died. Fortunately I've been using Time Machine to back up to a 2nd external drive. How do I restore my libraries to a new external hard drive?

This is a tricky one.
Open up Time Machine and go back to a date using the timeline on the right side of the window when you know the drive was working and was backing up as part of Time Machine backups.
Click on the name of your Mac under the Devices heading on the left side of the window in Time Machine, and if things are working correctly you will see Macintosh HD (or whatever you have named it) and the name of the external hard drive that was backing up in the past.
Right-Click on the name of the external hard drive and then click on "Restore (name of drive) to....." You may be asked for your adminstrator password at this point.
It might be easier to restore the drive contents to your desktop if you have room on your Mac, and then copy things over to the new external drive where you want to store the Aperture and iMovie Libraries.
Once the libraries have been moved over the new external hard drive, you will likely need to "point" Aperture and iMovie to the location of the libraries on the new external hard drive.

My Macbook won't start, and I must reinstall the disk. I haven't used time machine to back up, and I want to use an external drive to back up now. How can i do this from the utilities page?

I am currently in Zambia on missions work and my computer is constantly exposed to heat. I have just been trying to avoid using it during the hottest part of the day. Today though, I started it up and it was stuck on the grey page with the rotating circle for over an hour, then once the circle left, it remained frozen on the gray page. I used command + r at startup to go to the utilities page to analyze the disk. It found that there were problems with the disk, but then it could not fix those problems and told me to backup as much information as I could and reinstall or redo it all. I haven't ever used time machine to back up any of my information, but i have an external drive that I can use right now to backup my files. I can't get into my computer though to backup the files. How can I use this external drive to backup my files while the computer is currently messed up? Please help.

Emergency Backups (Data Recovery)
A)          Format an external disk:
          (This will erase all data on the external disk.)
          Boot in recovery mode (power then Command-R).
                    Alternative: Network recovery boot (power then Command-Option-R keys)
          To format (and erase) the destination recovery disk:
          Plug in the drive you are about to erase.
          Select the volume that is NOT your system disk.
          Click on Partition.
          Pull down under Partition Layout to 1 Partition.
          Click on Options…
          Select GUID Partition Table.
          Name: Emergency Backup (or whatever you prefer)
          Format: Select Mac OS Extended (journaled)
          Click Apply.
          Click Partition.
B)          Try to boot in Safe Mode (power then Shift key).
          (This will be a slow boot. Be patient.)
          If it won’t boot in Safe Mode, jump to C.
          If it boots in Safe Mode, try to boot in normal mode.
                    If that fixed your problem then start a Time Machine backup.

                    https://discussions.apple.com/docs/DOC-4055
          If not, boot in Safe Mode again.
          Go > Computer.
          Double click on the system disk.
          Drag the Users folder to the recovery disk.
C)          To clone the disk:
          Boot in recovery mode.
          Select Disk Utility.
          Try to repair the system disk twice.
          Whether or not the repair succeeds:
          Drag and drop the system disk to Source:
          Drag an drop Emergency Backup to Destination:
          (Take care not to reverse this order.)
          Click Restore (the lower Restore button).
Once your system is healthy, maintain two reasonably current backups. (Time machine restores can fail.)
Create either two Time Machine backups (good) or one or more Time Machine backup(s) and one or more bootable-clone backup(s) (better).
          Use Carbon Copy Cloner or SuperDuper! to create bootable-clone recovery disks.

Re Time Machine
I have an external hard drive with files I backed up manually over the past 2 years 1TB of memory.
I am finally taking the leap to use Time machine to back everything.
will I have to reformat that drive, thus wiping my previous back ups?
can I split it the drive in two partitions?
Also
as I have two separate Macbook Pro's- one older than the other.
OSX 10.68
the other is
OSX 10.75
can I back them up separately?
or even synch and merge files and folders etc? between the two?

You CAN use a drive with files already on it to store Time Machine backups. But long term, that is not recommended. You do not need to reformat or re-partition the drive to do this. Once Time Machine Backups are established, you could remove the old files.
But do not delete Time Machines files with the Finder -- that can cause it to lose its place and lose everything.
With the cost of backup drives under US$100, it might be a better idea in the long run to get another drive. Best results from Time Machine is a drive about 3 times larger than the drive(s) you are backing up.

Using Time Machine to back up an external drive?

I have an external HD containing my iTunes library attached to my Airport Extreme Base Station. Is it possible to use Time Machine to back up the AEBS-attached HD onto a different HD? I would connect the new HD directly to my MacBook and in an ideal situation, Time Machine would create a fresh back-up of my AEBS HD (iTunes library) every time I connected the second HD to my MacBook.
I may be making this more difficult than it needs to be. I just want to be able to back up my iTunes library to a second HD which I still have to purchase.
Any ideas?

Yes, just be sure the drive is online and not in the exclude list. Note that TM can only backup to one designated backup drive. If you add a second drive for backup, TM cannot use it and the currently designated backup drive simultaneously.

Is it possible to use time machine to back up a hard drive?

Is it possible to use time machine to back up a 1 hard drive onto another, then periodically update the backups just like I usually do with the Mac HD onto an external?
Thanks!

I don't know what you usually do but Time machine is a backup software. it does back up one (or more) hard drives to another. it's not a mirror utility though. it makes and keeps regular incremental backups and you can restore from any time point in the past you have a backup for. i suggest you consult pondini's FAQs at the top of TM forum

Not those whole folders, but their contents, maybe.
If the user account now on the Mac has read rights to the user account(s) on the backups, yes. If not, you may have to do some finagling.
Try the Browse Other Backup Disks option, per Time Machine - Frequently Asked Question #17. If you find an account that can open those folders, restore what you want to an alternate location (#16 in the FAQ).
If not try creating one or more accounts temporarily.

I have been using time machine to back up my Mac Book Pro 3.1 to my Time Capsule. Now the Time machine hangs up on "calculating time remaining".
Mac Book Pro - 3.1-15-inch 2.4/2.2GHz), Processor 2.2 GHz Intel Core 2 Duo
Operating system : OS X 10.10.1
Time Machine Version 1.3, Copyright 2007-2014 Apple Inc., Modified Tuesday, September 9, 2014 at 6:03 PM
Time Capsule: 500 GB C 2007
This Time Machine software worked satisfactory until Monday Nov, 10 2014 and I have backups until that time. For several years, the software deleted the oldest back up to save the latest one. This is acceptable to me as I have off site storage that is updated every 3 months. How do I get Time machine working again?

I have spent a couple of days trying to respond to Linc Davis. Finally I figured it out . The following is a copy of data from my console from the initiation of a time machine backup until it gets stuck trying to calculate the time remaining. There is no indication that anything starts saving. I copied about 3 minutes of data. This is probably way too much data, but I do not know what is relevant.
Thanks for the help,

I would like to use time Machine to back up to a network SMB drive. I can see the drive on my desktop but it will not show in the time machine window to be able to select it

I currently have a mini server (OSX10.8.5, server 2.2.2) that I am using Time Machine to back up 4 external drives that are connected to the server via firewire 800. I would like to use Time Machine to back up to a windows network SMB drive. I can see the drive on my desktop but it will not show in the time machine window to be able to select it for use.
Can this be done
Thanks for any and all help

The supported targets for Time Machine backups are local (direct-connected) disks, and network targets include Time Capsule, a disk hanging off the current-generation AirPort (though not earlier AirPort devices), and OS X Server systems.
The Time Machine storage is based on the HFS+ file system, so I would not expect TM to work with SMB file services.
While there are hacks to allow Time Machine to access network drives, I would not consider those to be reliable. Skim the forum and the 'net for related details, and for previous discussions of setting this up and the related issues that can arise.
Remember to test the recovery with whatever you decide to use; whole point of backups is the ability to restore the data, after all.
If you want to learn more about Time Machine, Pondini is an excellent resource.

Can we use Time Machine to back up data on Time Capsule from the outside of network?

I have Time Capsule at home. Can I use Time Machine to back up data of portable nootebook when I am working at office?

If you mean over the internet, you can but it will be so slow and more than likely so unreliable it is a poor method to use. Remember all internet is limited to upload speed.
Lion does a temporary backup onto local hard disk.. which is useless of course if the hard drive is damaged.. but helps if you delete an important file. Then when you go back home and it discovers the TC is available it will then backup again from where it left off.
I think it is only a major issue if you are away from home for major lengths of time, weeks or months.

Using time machine to back up additional external drives

My mac mini contains a 160 gb hard drive. Aiming to keep this free, I connected a 500 gb WD mac-specific hard drive. I also use this drive when attempting to access work files on my macbook pro. When using time machine, which backs up to a 1 TB WD hard drive (also attached to the mac mini), I cannot figure out how to use time machine to back up simultaneously the contents of the native (160 gb) drive in the mac mini and the contents of the portable external drive (500 gb). *Is there any way to set time machine to accomplish this?* Please help - I really need to continually back up the contents of the portable drive as well.

carbon copy cloner will do this. you set up a scheduled job (can be daily, weekly, etc. & even every hour!) & is free to use (donations accepted).
