Backup an external hard drive to a time machine hard drive

I know that in snow leopard a second hard drive that is connected to the computer was automatically excluded from the time machine backup. In order to included it you just removed it from the list.
How do you get your second hard drive to be backed up in time machine on lion?

As Link pointed out in that thread, there's a lot excluded:
Dec 26 12:29:11 Branch-iMac com.apple.backupd[3876]: Backup content size: 340.7 GB excluded items size: 256.3 GB for volume Media Server
Thus there should be about 80 GB that's included.
And part of it WAS backed-up:
Dec 26 15:43:56 Branch-iMac com.apple.backupd[3876]: Copied 3986 files (13.6 GB) from volume Media Server.
He's also shown some things that aren't being backed-up, and suggested a couple of things to do, but you haven't responded to his last post.

  • Trying to use a new, larger external hard drive for my Time Machine backup.  However, every time I start the backup, it gets started then fails.  And, I can't delete the few files that did save on the external.  Sort of a catch 22.  Any ideas?

    Is it a USB hard drive?  USB hard drives have the problem of not giving full speed if they are hooked up on the same bus as keyboards and mice.  Double check your profiler to make sure that is not a problem.  If it is Firewire, make sure there aren't other firewire devices in use at the same time.  I recommend not only keeping a Time Machine backup, but also a clone, and if you do use Time Machine, to make sure the Time Machine drive or partition is at least twice the size of the original drive.

  • I have a 250GB western digital external hard drive for my time machine backups. if i just want to backup and recover my photos and movies how do i do that with time machine?

    I have a 250GB western digital external hard drive for my time machine backups. I did not download the software that came with the external HD. If I only want to backup my photos and movies from my Macbook how do I do that in Tme Machine with my external HD?

    Format the HDD in Disk Utility>Erase to Mac OS Extended (Journaled) and the open System Preferences>Time Machine and set up the external disk as the Time Machine HDD.  Then look at the Options, and exclude what you do not want backed up.
    Ciao.

  • External Hard Drive ejects during Time Machine Backup

    I've read through all the troubleshooting pages that I thought had anything to do with this problem, but none of my error messages seemed to match. This is my first backup with Time Machine onto my external hard drive, and it never gets past about 60GB before deciding that the drive has improperly ejected itself and aborting the backup. The error message from my Time Machine Buddy is below:

    Other details:
    My external drive is a WD 1TB drive. The partition for the Time Machine Backup is formatted as Mac OS Extended (Journaled), as is my Macintosh HD. The Partition Map Scheme on the external drive is GUID Partition Table.
    I have tried reformatting the external drive for good measure, but this doesn't seem to solve any problems. I also tried searching for the file that the error message says NO Copying for (/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/g ems/net-ssh-1.1.4/lib/net/ssh/proxy/...) but I'm unable to find the files. I can get as far as /System/Library/Frameworks, but can find no folder in Frameworks titled Ruby.
    Please help.

    The Ruby folder is probably hidden. That is why you don't see it.
    You may want to add System/Library/Frameworks to the exempted sync list until you can figure out which file is causing this. You can do this by opening Time Machine Preferences ( > System Preferences > Time Machine) and clicking on Options…
    After that click the small + key and browse to the folder you want to exempt from the sync. In your case: Macintosh HD > System > Library > Frameworks
    Next hit the exclude button with the Frameworks folder highlighted.
    Try your backup again and see if it fails.

  • I would like to connect an external hard drive to my time machine and use it as a network drive to store itunes and iPhoto  how do i do this

    I have just purchased a new my book hard drive and would like to connect it to my time capsule and store my itunes and iphoto contentent there to free up space on my internal hard drive . Can this be done and what is the process?

    I'd like to store my Aperture /IMovie Libraries on an external hard drive.
    That is fine and recommended.. use the fastest disk you can afford.. ie Thunderbolt>USB3>FW800>USB2.
    In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives.
    Let me be clear.. you want to partition the one disk.. use it for TM and move your files to the external disk.. and then backup to the same disk.. You can do it.. but that is not a backup.. that is an experiment in how long you can get away with running files and backups on the same disk before you lose everything.. like Russian Roulette.. pull the trigger enough times and laws of probability will do you in.
    You must have backups on a different disk .. otherwise it is pointless.
    Can I set up a RAID 5 format for redundancy?
    No.. you can buy special USB and Thunderbolt external drives that support RAID..
    BUT that is still not a backup.. let me show why.. you make a silly move and corrupt your file in aperture.. it is not that rare.
    Raid will corrupt all copies of the files.. it is replicated across all disks.
    Delete a photo it is deleted across all disks.. you have no recovery.
    Alway, always consider RAID system one disk.. backup onto another disk.. and if the photos or movies are at all important to you.. ie your family .. make another copy and store in a relatives house.. There is no such thing as too much redundancy.

  • How do you remove back up data from the memory storage? my storage data states that i have over 80gb of data used for back ups and i dont know why as i use a external hard drive as a time machine .now my 250gb flash storage is nearly full

    When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as  Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
    See this support article for some simple ways to free up storage space.

  • HT201250 how do i add external hard drive to my time machine back up

    how do i add external hard drive to my time machine back up so that I may view the files independently on apple tv please?

    To elaborate on above.  I am looking to add about 300gig of photos on an external hard drive to TC. 
    Once I do this I believe I can then have itunes source its photos from TC without having them stored directly on my iMac? 
    Then I am assuming once I keep itunes on with home sharing I can stream these photos through Apple TV?
    My inital problem is getting the photos onto TC in an individual folder not just a backup folder....is that possible or what would you suggest please?

  • I have an Apple Macbook and will be backing up the entire system to an external hard drive utilizing the Time Machine application. when I am doing this, will the data on the external drive that I am using be erased?

    I have an Apple Macbook and will be backing up the entire system in order to upgrade to a newer OS. I will be using an external hard drive to do this and there is already data on it. To complete the backup, i will be using the Time Machine application. Does this application wipe out all of the existing data on the external hard drive, or will it create a new "folder" for the backup?
    thank you

    No, but as steve359 states you should use a dedicated hard drive for backups. It you need a temporary backup then you can use the drive provided it has sufficient space for all your data on the hard drive.
    When Time Machine finds that the drive has data on it already it may decide to erase the drive before continuing, which is another reason to use a dedicated drive.

  • External hard drive setup for time machine reading as a virtual cd

    Why is my MacBook Pro reading my external hard drive setup for time machine reading as a virtual cd?
    Thanks

    Hi Christian,
    Is this something that has happened from the start? If so, I would reformat the disk and setup TM from scratch again.
    Prepare the external HD by connecting to the Mac, open Disk Utility, select the manufacturer’s name of the external HD, select Partition and choose GUID Partition Table, format to Apple OS Extended (Journaled); quit Disk Utility.
    Open System Preferences.
    Click on Time Machine.
    Click on “Select Disk.”
    Click just to the left of "On" to turn TM on if it's not already on.
    Click on the disk or partition you want to use.
    Click on “Use for backup.”
    Leave external HD connected, and TM will automatically do its thing.

  • External Hard Drive--Storage Device/Time Machine

    I recently purchased an external hard drive compatible with Time Machine.  I understand this application serves as a backup system.  I am beginning my first year of teaching this fall and also need to keep a few copies of all of my teaching materials.  Can I still use the external hard drive as a storage device (more like a flash drive)?  How do I go about this and use it for both?  Or should I just use it more like a flash drive for the purpose of keeping copies of my teaching material?

    Welcome to Apple Support Communities
    Of course. You can use the external drive to make Time Machine backups and to store other data. The only thing you have to do is to create two partitions on the external drive through Disk Utility > http://pondini.org/OSX/DU3.html
    After doing this, you will have to use one partition for Time Machine, and another one to store your files. It's important to make Time Machine backups, as they allow you to restore the whole system if the hard drive fails. See > http://support.apple.com/kb/HT1427

  • I have a time machine backup file on a USB hard drive.  I bought a time capsule / airport extreme, flat 3TB.  I wish to transfer the backup file from the usb hard drive to the time capsule hard drive.  10.6.8

    I have a time machine backup file on a USB hard drive.  I bought a time capsule / airport extreme, flat 3TB.  I wish to transfer the backup file from the usb hard drive to the time capsule hard drive.  10.6.8

    Unfortunately, Time Machine backups that are stored on a drive that has been connected directly to a Mac are completely different than Time Machine backups that are stored on a Time Capsule.
    Frankly, it is not worth the effort and trouble to try to transfer the old backups to the new Time Capsule.....my opinion....having done this in the past.
    It is possible though, but I would not recommend it due to the complexity and downsides involved with this. To give you an idea of how to do this, check out this support article.
    http://pondini.org/TM/18.html
    Even if you transfer the "old" backups over to the Time Capsule successfully, Time Machine will not simply "add on" to the old backups.
    Time Machine will make a new complete backup of your Mac and then add incremental backups from that point.
    My advice.....start a new backup on the Time Capsule and move forward. Keep the USB hard drive around for a month, maybe 2 or 3 in case you need to go back to an old backup for some reason.  At that time, you will not likely need the old backups at all since you will have a current 2-3 month history of new backups.  At that point, you can erase the USB drive and use it for another purpose.
