Time Machine to back up an external HD.

My iTunes library is on an external hard drive. I would like Time Machine to include it in its backups.
Can this be done?
If not, is there other backup software I should consider?
-Ron.

yes, it can be done. TM will back up external drives by default. the external has to be formatted HFS+ (= Mac OS extended) for that. also, make sure you have enough space on the backup drive.

How can I get Time Machine to back up an external hard drive (iPhotos) that is attached to airport extreme base station. Note: Time machine is usb to macbook pro and external drive with iphotos is usb to airport extreme base station. Help please. Thanks!

Once you have the drive connected to your Mac, click System Preferences (gear icon) on the dock
Click Time Machine
Click Options
Be default, the hard drive will be Excluded from backups. Click the drive to highlight it, then click the "-" (minus) button at the bottom of the list to remove the drive from Excluded items.
The drive will be backed up on the next Time Machine pass
Everything above assumes that the hard drive has been formatted in Mac OS Extended (Journaled) as Time Machine will only backup drives in that format.

Having trouble getting Time Machine to back up my external hard drive. Any suggestions?

I'm running Mountain Lion on my iMac and I've been using Time Machine to back it up to my Time Capsule. Recently, the iMac's hard drive filled up, so I moved my iTunes library to a new Airport Time Capsule. But I can't seem to get Time Machine to include the new Airport Time Capsule in its back up.
The only suggestion I can find is to make sure it's not excluded in the Time Machine options, and I can see that nothing is excluded. However, when I go into Time Machine, the Airport Time Capsule is greyed out in the Finder window.
Anyone have any ideas? Thanks in advance, I'm a little nervous about having my iTunes library hanging out there without a back up...

You can't back up the internal drive of the Time Capsule with Time Machine. It will only back up locally attached storage devices, not network devices. There's no way around it. You may be able to back up the TC with third-party software such as "Carbon Copy Cloner," but it will be very slow. The internal drive of the TC is only suitable for use as a backup device. It's not suited for storing original data.
yeah well you can use the external hard drive as a data extension to the time capsule internal hard drive. like a RAID in effect...

I can not get Time Machine to back up an external WD Passport 2 TB drive! Has anyone else had this problem? The drive is new and I was running Snow Leopard and upgraded to Lion and it still won't do it. Time Machine backs up the internal drive fine.

I bought 2 2TB WD Passport Drives with the intention of housing my iTunes/iPhoto libraries off my older MacBook. I have successfully transferred the Libraries to one and am using the other one for Time Machine. In Snow Leopard I could back up my computer to Time Machine no problem but when I did not exclude the iTunes/iPhoto drive the back up fails. Both drives have been reformatted, permissions repaired and checked in Disk Utility and one was replaced. I have been to the Genius Bar now 5 times. I have tried using USB drive and FireWire. Both drives are recognized and are working properly otherwise regardless how they are connected. Finally yesterday the Apple store installed Lion to see if that fixed the issue and it did not. Time Machine successfully backed up a USB Flash drive, and today I will try an older external drive. Any ideas on what else to try??? Do I have to resort to third party software like Carbon Copy Cloned to get this done? Any ideas why this wont work? I am using a FireWire converter but as I said, both drives are working normally otherwise (libraries working, time machine working for the computer's hard drive. Any ideas would be appreciated!!?

Thanks so much but none of that helped. It was driving me crazy because it would back up another external drive. I just changed the name of the drive from iPhoto/iTunes Library to Media Libraries and IT WORKED!! I guess for some reason it didn't like the drive being called iPhoto or iTunes ???? I don't understand but I have tried so many solutions and exchanging things out but the name change did it????!!!
Thank you for your help and replying to this. Guess I made my own issue!

Using Time Machine to back up an external hard drive dedicated to Adobe Lightroom 5

I recently began to use Adobe Lightroom 5 (I continue to use Aperture, as I have for years). All of the Lightroom image files and catalogs are on one external hard drive, which I use on my iMac, my Macbook Pro, and in the digital labs of a school where I'm taking a course.
Not yet having developed a protocoI for creating a back up of all my Lightroom image files and catalogs that I could use in the event of my Lightroom-dedicated drive's failure, I have just done a drag and drop of the whole drive's contents to another external drive (which, as it happens, I have been using for some time for my Aperture vaults).
I am thinking of removing the dedicated Lightroom drive from the excluded list of my iMac's Time Machine (which uses yet another external drive), so that I can easily and automatically create back ups of changes to the Lightroom external drive without having to do the cumberome and inelegant drag and drop at some yet-to-be-determined frequency. (The Macbook Pro uses a Time Capsule for its Time Machine; I envision using only the iMac's TM external drive for Lightroom backups.)
What is the simplest and most desirable way to actually execute the backup? I envision that it would be this: that every time I want to do a Lightroom back up, I'd mount the Lightroom external drive on the iMac (or keep it mounted if my work session has just been on the iMac) and then ask Time Machine to "Back Up Now." When the backup is finished, I'd dismount the dedicated Lightroom drive.
A related question is what if anything would be the effect on my Lightroom work if a Time Machine back up began while I was working in Lightroom? Or if for some reason an hourly TM back up began and I needed to quickly end a Lightroom session before the backup was completed?

Time Machine not backing up 2nd external drive, remove option grayed out

I have two external hard drives, 300gb (firewire) and 500gb (usb). Time Machine is backing up to the 300gb. In Time Machine's options, the 500gb is excluded from being backed up, and the remove option is grayed out.
The 300gb Time Machine Backup drive is formatted as Mac OS Extended. The 500gb drive is formatted as MS-DOS (FAT32).
I know the backup drive needs to be formatted as Mac OS Extended, but will it not even back up other drives that are FAT32?

I am having a similar problem. I initially set it up 3 days ago and had it back up just the iMac to Time Capsule (about 120 GB) which it did no problem (I initially had my LaCie drive excluded). I then un-excluded my other drive, where all my photos and music reside (about 130 GB). Since then, it keeps trying to back up about 102 GB each time. Looking at the list of backups it does not appear that it has ever successfully backed up the LaCie. I am not aware of any error messages, but I have not been home much. I normally shut down the computer at night but I have been leaving it on trying to let Time Machine do its thing. All I can say is that every time I am at the computer TM is running and it always looks like it is in the middle of backing up 102 GB (usually seems to be near the beginning, never seem to see it more than halfway done). Looking at the TM panel it says the latest backup was 2 days ago. I'd appreciate any advice!

Will Time machine automatically back up an external hard drive connected to my iMac?

I have a Lacie external firewire hard disc connected to my iMac, containing Aperture library. Will Time Machine automatically back up both the external disc and the iMac HD?
Adrian

Will Time Machine automatically back up both the external disc and the iMac HD
Open System Preferences (gear icon on the dock) and open Time Machine
Click on Options
Do you see the name of your Lacie drive in the "Exclusions List"? If yes, the Lacie drive is currently not set to backup with your Mac.
Click on your Lacie drive to highlght it, then click the - (minus) button at the bottom of the list to remove the drive from the "Exclusions" list.
Now, Time Machine will backup both your Mac and the Lacie drive on the next pass. Allow plenty of time for this backup, avoiding wireless if possible, and connecting the Mac directly to one of the Ethernet ports on the Time Capsule. Ethernet will go 3-5 faster than wireless, on average.

Can you use time machine to back up an external hard drive?

I haven't used Time Machine so far and setting it up now.
Because my retina MBP has the limited hard drive size of 500GB, I'll be using a 2TB G-Tech hard drive as external hard drive.
I'll be partitioning it, 500 GB for the MBP as a time machine back-up, the rest as a hard drive for photography RAW files.
Can I set up time machine to back up the larger partition (the one with the RAW files) to a second external hard drive? Or does Time Machine only handle back-up from the main computer hard drive?
thanks!

Try reviewing this information.
Time Machine FAQ
You will definitely need more than 500 GB to use Time Machine - see question 1.
Time Machine works with the main hard drive and any locally attached storage, but I don't know of any way to make it backup the second partition without resetting the Time Machine Preferences. You can do that with a cloning program.

Two backups are better than one. Drives do fail.

Does Time Machine also back up wired external hard drives?

I apologize if this is already answered; I can't find the answer. But I am running out of space on my hard drive, and I am thinking about moving my music and movies (ie multi-media content in iTunes) to an external hard drive. I am torn between two options. 1) use my existing external hard drive (LaCie d2 Quadra 1T) and partition it for Time Machine and a Multi-media folder, or 2) just buy another external hard drive, likely another LaCie and dedicate it for my multi-media. I lean towards keeping my back-up hard drive as is -- for one purpose so as to minimize loss of data should (when) the unthinkable happen. Anyhow, I'd like to know whether Time Machine can be told to include my 2nd external hard drive in its regular back-ups. Likewise, if I partition my current LaCie, can I tell Time Machine to back up my multi-media folder? Any info or links you can provide is appreciated. Regards.

I appreciate the comment. Is there a way to find out whether Time Machine backs up external hard drives without having to buy one and plug it in to see if it is listed in the Time Machine pane of System Preferences? If I could read between your lines, I assume you are saying is Time Machine is "smart" enough to include external hard drives provided that I don't exclude it. Right? PS - I will be using the Mac OS Extended (Journaled) format.

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).

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.

Time Machine not backing up other external hard drive

Hi,
I recently upgraded to Leopard and am trying to use Time Machine. I have one external hard drive that is used specifically for the Time Machine Backup, it's called "Backup Drive". The other hard drive is called "Captured Memories" and is used to store my graphic design files. Time Machine seems to backup my iMac because there is a folder called iMac and it contains the files, but the folder for Captured Memories is blank. I was getting errors saying that the backup failed but when I clicked the "Back Up Now" option on Time Machine, it doesn't list the error - but the Captured Memories folder is still blank so it didn't back up that external drive. I also changed the Spotlight preferences so that it does not search the Backup Drive.
Both the Backup Drive and the Captured Memories drives are the same, they're both Seagate Free Agent Pro drives, 1TB each.
The Free Agent Pro drives both have a sleep timer that I cannot adjust, does that have anything to do with why Time Machine won't backup the Captured Memories drive? If that is the case, what other software can I use to backup the Captured Memories external drive? I want it to sync to the Backup Drive because I am constantly saving and moving files around on the Captured Memories drive.
I was using a Memeo backup software that came with the Free Agent Pro drives but the problem I was having is it would make copies of files rather than move them. For example, I have a folder on the Captured Memories drive that is called, In Progress and one that is called In Proofing. So once a project is complete, I move the file to the In Proofing folder. The Memeo software would copy the file to the In Proofing folder rather than move it. So I'd end up with 2 copies of the file, one in the In Progress folder and one in the In Proofing folder.
Does anyone know how I can simply have the drive backed up like that?
What do I do?
Please help! I really need to make sure that the Captured Memories external drive is being backed up!

How can I tell if Time Machine is backing up my external HD?

Mac Newbie here. I just have a quick question: I have two external HD hooked up to my 2012 iMac, one holding media files (not iTunes, just miscellaneous avi and mkv type files) and the other serving as the backup drive for use with Time Machine. When I first hooked up the media external HD, the OS asked me if I wanted to use it with Time Machine. Interpreting that as a request to use it as the backup drive, I replied "no." Then when I hooked up the second external HD, I replied "yes" when asked if I wanted to use it with Time Machine.
Since that time, Time Machine has been running smoothly, but I'm not sure if it is backing up both my internal HD and my external HD #1 used for media files. When I open Time Machine using Launchpad, it shows me a picture of Finder listing all my different hard drives, but only in the "now" timeframe. When I go back a few backups, the external HD used for media files is grayed out. Does that mean it has not been backing up my external HD files? If so, how do I tell it to include that external HD in the backup process?
Note that I am trying to backup contents of one external HD (including my internal HD) to another - the internal HD has 1 TB, the first external HD has 2 TB, and the second external HD has 3 TB (this is the one I'm using as the backup drive). So I think I should be ok from a space standpoint.

Open System Preferences > Time Machine > Options and see Excluded Items. If the external drive is there, it's not being backed up

If I move my iTunes media folder to an external hard drive, will Time Machine still back up that externally-located iTunes library?

To be precise, I've moved my iTunes Media Library to the same external hard drive where my TM backups are stored, although there's plenty of free space on that drive for both.
As I write that, however, it strikes me that if that external drive fails, I've lost my entire iTunes media directory AND my TM backup. So I suppose I should use a separate external HD for each, right?
But my main question is whether or not TM will still back up that iTunes media folder even if it's no longer located on the same boot drive as my main machine, which is a Mac Mini.
The whole reason I'm doing this is because my MM has a 250GB solid-state drive that is rapidly filling up because my iTunes library is 150+GB.

mende1 says:
I recommend you to store the library on another partition on the external disk and keep the first volume only for Time Machine backups.
and you say:
As I write that, however, it strikes me that if that external drive fails, I've lost my entire iTunes media directory AND my TM backup. So I suppose I should use a separate external HD for each, right?
From what people report here I'd say more people lose collections through whole drives failing and not just individual volumes becoming corrupt. A drive failing will take out all volumes on that drive.
Whatever the scenario, you will need multiple external drives. For convenience you could do as mende1 suggests and partition the TM drive. Keep TM on one part and your library on the other. This would be convenient because then you would only have one external connected to your Mac most of the time. However, then you should do as you observe and back up the partition used for iTunes to another external drive as often as you deem necessary. Basically you always want two copies of everything on two different drives, but they don't all have to be on the same two drives. Your TM drive acts as the backup for your computer and the primary for iTunes. Your computer acts as the primary for what's on TM and the second external acts as the backup for iTunes.

Using Time Machine to back up an external hard drive

Hi,
This has probably been asked a lot but i'm struggling to find an answer. I want to back up my external hard drive using Time Machine but i'm not sure how to do it?
Is there a way that I can connect my external hdd and create a back up that is stored on my mac?
If this was possible, does Time Machine take a snapshot or does it duplicate the data (in other words would this take up a huge amount of storage on my laptop)?
I don't use Time Machine as I generally don't store anything on my laptop, but my external HDD holds all my photos.
Any help is much appreciated.
Thanks,
Hannah
