  • Does Time Machine backup External HDDs?

    Hello everyone, I plan to use a Mac-Mini as an HTPC, and want to use a large external HDD connected DIRECTLY to the mini as my storage (call it HDD-A).
    If I connect a second external HDD dedicated for TM (HDD-B), will it backup content from HDD-A as well as the OS?
    Q2: Are there any special settings in TM necessary to accomplish this?
    Q3: Separate TM question: Anyway to get TM to backup an External HDD that's connected to an AEBS?
    Thanks much in advance!

    I am in the same situation, riesar. I have 2 time-machine-enabled macs connected to a 500GB Time Capsule. My Mac Pro has 4 drives (boot, bootClone, Video Archive, Video Archive Clone) I use Time Machine to backup my Main boot drive, with a couple of exclusions including all other HD's. I excluded my Parallels folder since Each windows installation is about 10GB and the ENTIRE file changes each time you open your virtual PC. I also exclude my parallels installation from my iMac Time Machine file as well.
    Every couple of days, My Boot drive clones itself (using SuperDuper!) to the BootClone and the Video Drive clones itself to the Video Clone. I don't have incremental backups of my video (or Windows installation) but I save SIGNIFICANT space by excluding certain things from time machine. My iMac clones itself to an external firewire drive as well.
    If you were REALLY cramped for space on the Time Machine volume, you could simply include only - say - the User folder. You'd sacrifice the ability to restore your system to a previous state, but you'd have incremental backups of all your regularly changing data files. Your clone could restore your system, but if you ever had to restore your system, your recovery is only as good as you last clone. YMMV.

  • Can I have two Time Machine backup external drives on one Mac?

    I have been using Time Machine for over a year and like it very much. The thought occurred to me that I should buy a new external drive that I can backup to and store at a remote location. I plan on making a backup each week, then taking this new drive to my office. That way, if my house ever burns down, I have a backup at my office too that will be a fairly recent backup.
    When I unplugged my older external drive and tried to launch a backup using the new one, my Mac said it couldn't find my Time Machine drive. Won't it let me backup to two different drives? Or does it always need to backup to the same one?
    Thanks!

    Yes. All you have to do is tell it you've changed destinations, via +Time Machine Preferences > Select Disk.+ (Use different names for the drives, so you know which one is which.)
    Try not to go too long between "swaps," though. After several days, especially if there's been a large volume of changes, Time Machine might do a new, full backup, instead of an incremental one.
    However, I've learned over the years (mostly the hard way, of course ), never to trust my backups to a single app or piece of hardware: no app is perfect, and all hardware fails, sooner or later.
    Like many here, I keep both full Time Machine backups, plus a "bootable clone" on a separate external HD. I use CarbonCopyCloner, many use the similar SuperDuper. That gives me the best of both types of backups, plus of course a completely separate, independent backup.
    CCC is donationware; SD has a free version, but you need the paid one (about $30) to do updates instead of full replacements, or scheduling. Either is easily found via Google.
    And/or, see Kappy's post on Basic Backup, complete with links to the web sites of each product.

  • Time Machine Backups external drive developed problem which the disk repair utility cannot fix, so suggested reformat. I can't reformat because the "Resource Busy". How can I reformat this drive?

    My Western Digital external hard drive which I use as a Time Machine Backup stopped working. I tried repairing the disk using the Disk Utility program,but got the message that the utility can't repair the disk and to erase and reformat the disk. When I try that, I get the message the operation can't be completed because "Resource Busy", even though Time Machine is turned off. Any suggestions for repairing the drive/disk?
    Thank you.

    See Pondini's TM FAQs for starters.

  • Would Time Machine backup external hard drive attached to my Mac?

    I have a hard drive which is attached to my iMac 24*7. I plan to move all my movies & pictures over to it. Would the Time Machine backup (through a different hard drive) backup my Hard drive?

    Yes, TM will back up any Mac-formatted volume attached to your Mac.

  • Time Machine: Must external HDD be a large or larger than internal drive?

    I have a 2TB HDD in a new iMac, and I have a couple of spare 500GB SATA drives I can liberate from my previous Mac. Before I buy enclosures for the externals, I'd like to know if TM requires an external drive the same size or larger than the internal drive it is to back up.
    Though I have a 2TB internal drive, it has 1.79TB available, and I could probably use a 500GB for quite a while before I need a larger backup drive.
    Thanks.

    If you have only 210 GB on that 2 TB drive, then yes, a 500 GB drive will probably work fine, at least until you put a lot more data on your system.
    It does vary a great deal, of course, depending on how you use your Mac. If you frequently change and/or replace a lot of large files, you may fill it up rather quickly; if not, it may not fill up for quite a while.

  • Time Machine w/ external HDD question

    Hello all!  Just started using Time Machine with an external HDD.  So, here is my question, if my HDD (USB) is not attached for a week, and Time Machine is running, will I get some sort of error message letting me know that the backup volume cannot be found?  Also, when I reattach, say one week later, will Time Machine pick up and backup those items over the past week?  Please advise.  Thanks!

    Time machine might give you an error but its very unlikely. And as for unplugging the drive, yes time machine will pick up were it left off and update the changes you have made. I usually only hook mine up every couple weeks cause I don't make very many changes.

  • Time Machine using external HDD docking stattion

    Hi,
    I have a Macbook Pro and a few internal HDD's lying around. I have found on the web some external SATA docking station for mounting internal drives using Firewire 800. I am wondering if Time Machine will recognize these the same as normal external drives and backup accordingly. Thanks.

    No reason why that shouldn't work. TM knows when a drive is not available, and it will resume a backup once the drive is connected.

  • Time Machine Backup After HDD Upgrade

    I recently updated my drive on my MBP with a larger size where I successfully cloned the system from the old drive over the new one with Carbon Copy Cloner to safe me the hassle of the migration. The task was flawless and transparent to the system and me--as a user, except for Time Machine.
    I've maintained a regular backup with Time Machine on a 500gb external drive, instead of transparently picking the backup where it left off, Time Machine is attempting to redo the backup as a complete new set for the new drive where I no longer have enough space?
    So the question is:
    - Is this behavior by design?
    - Is it possible to trick Time Machine to continue backing up without starting over? So the 6 months old worth of backup data is intact since this is the same set of data?
    Thank you.

    no. TM will do a full backup after hard drive cloning. there is no way around that. you have to either delete some old backups (this can be done from TM interface) or reformat the TM drive and start backups from scratch or use a different backup drive.
    So the 6 months old worth of backup data is intact since this is the same set of data?

  • Time Machine: changing external HDD

    Dear All,
    I'km kinda new to mac, just recently made the switch so if my question has been answered already for like a hundred times I'm really sorry.
    I started using time machine a week ago using my smaller External HDD, a 160GB one.
    I have bought a new, bigger one (1 TB) which I'd like to use since I think the smaller one will be full in a couple of days. I was wondering however: is there a possibility to transfer the updates I already made (on the smaller one) to the bigger one so I can switch external HDD without losing the old back ups?
    Thnx 4 ur help!

  • Can Time Machine backup External Disk

    Hi,
    I have MacBook Air and have to use an external disk (Western Digital) to save my iPhoto Library and my iTunes Library (both libraries are approx 400GB).  I am using a 3TB Time Capsule with Time Machine.  Is it possible to backup the external WD disk with Time Machine?  I would hate to loose the libraries if something happens to the external disk.
    Any help or suggestion will be appreciated!
    Thanks

    Thank you!   Sometimes you miss the obvious while thinking you have to look at something more complex

  • Time Machine backup & External Hard drive issue

    Hello,
    I have a MBP running Snow Leopard. I use two external Hard drives for Time Machime backups. The first one Seagate2TB is working with TM just fine. 
    The second one Seagate3TB worked with TM just fine for about a year until two days ago. Since two days ago, TM doesn't backup any new data (or file changes) anymore to this 3TB drive. It back's up only a few kb and cleans up, while it should backup at least 200Mb that I just uploaded to my MBP.
    Here are two (maybe) useful additional info:
    - I used disk utility to verify this 3TB hard drive and it returned okay. I also use this 3TB hard drive to backup a different Macbook and it still works just fine. 
    - At the same time, my TM woks on my other 2TB hard drive.
    Can someone please let me know what the issue is and how to fix it?
    Thank you very much.
    PS: These hard drives are connected to my MBP via a USB cable not time capsule.

    thanks for the suggestions -- actually, the "real" issue is that my technophobe spouse needs the "documents" file backed up. TimeMachine "should" work --does not. And because working from dropbox (which is a great idea and already installed) would mean opening up a file other than "documents" - it would cause such anxiety, I was hoping to write an apple script to back up the file daily to someplace else without me having to physically do it myself.
    Here is what I am trying --I will put the entire folder on DB and then create an alias (that looks like the same title as the original) and leave that on the computer -- I wonder if that will work?! 
    Or maybe I am confused. I thought I needed to work from the document in DB in order for it to sync there...
    Thanks again for the ideas!

  • Will time machine backup external 16gb USB pen drive?

    I have a Macbook at home but PC at work. I carry all of my work on a 16gb sandisk pendrive which i work off on both computers. I want to back everything on my mac as well as the pendrive (which i make changes on daily) to an external hard drive or time capsule. My question is: will time capsule check for changes on the pen drive and back them up or does it only check for changes on macbook hard drive? Up till now i have to drag entire contents of pen drive every time i want to back it up which is time consuming!

    TM will back up any directly attached drives but only provided they are formatted mac os extended. by what you describe your USB stick is formatted FAT in which case TM will not back it up. you can try using something like Chronosync to sync the drive when you need to. or you can reformat the drive mac os extended. however, windows can not read mac os extended format without extra software like Mac Drive which you'd have to get.
