TM won't back up other external drive

I have a LaCie external drive which contains all my photos and music. I have TM backing up to Time Capsule--it works fine with my iMac, but if I add the LaCie it starts backing up but never finishes. I have watched the progress bar get as far as maybe 70 out of 150 GB and then start over from 0. It will cycle like this indefinitely--I've let it run for as much as a couple of days and it never gets anywhere, no evidence of even a partial backup of the LaCie. TM basically will work only when the LaCie is excluded (I've switched back and forth a few times to prove this). Very grateful for any ideas!

PROBLEM SOLVED.
Recap: Time Machine would not back up an external data drive despite being correctly formatted and settings correctly applied.
Problem was either: a) the Mac, b) the external data drive, c) the Time Machine drive, or d) the data.
I replaced both the external data drive (cloned) and the Time Machine drive, but Time Machine would back up that external drive either.
Finally, instead of CLONING (SuperDuper) the external data drive, I COPIED the data to a new HD -- root folder-by-folder. Now Time Machine again backs up my external hard drive.
SOLUTION: Problem was not hard drives or Mac, but within the data itself. Cloning the data simply passed on the problem to the new hard drive. For this problem, the solution was copying the data rather than cloning.
Thanks all.

Time Machine won't back up OWC external drive

Mac Mini running 10.8.5. Time Machine will not back up brand new OWC MiniStack external HD. I've trashed TM prefs, reformatted the TM drive, verified that there are no exclusions, but it won't back up the external HD which contains only data files -- no system, no applications. TM does back up the internal HD.

Time machine back up other external drive?

Hi folks,
My HD is filling up fast. What I need to know is if I move say, my music and photos to an external drive, will time machine back up the music and photos when they reside on the external drive? I have time machine running on an external drive dedicated to time machine. I'm using OX Mavericks.
Thanks,
Steve

Mine is set up similar. I use TIME MACHINE as a back up and then my redundant back up is to a 2 terabyte USB External, so now I have everything backed up twice.

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!

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!

External Hard Drive for Time Machine - 2 TB. Can I remove other external drives it was backing up?

I have an external drive dedicated for Time Machine, it's 2 TB. Last year I started backing up computer (500 GB) and one external hard drive that has 500 GB. IAlso, I have another external drive that is 1 TB connected to my computer. I noticed last week that I was hearing that other external drive sounding funny, so I thought I would add it to Time Machine to back up. Now today my Time Machine failed. I tested the drive or verified the drive and all was well. My thought is because I added this drive to Time Machine it failed because of not enough room? Is there a way to remove that other external hard drive and go back to just the computer and the 500 GB?
I did btw out of a panic mode buy the GDrive that has Thunderbolt with 3 TB, yet I can't use Thunderbolt because that plug is used for my monitor, bummer. But, maybe using this new external drive I can back up the 500, the computer and the 1TB. Any thoughts?

When you say the Time Machine failed, do you mean the drive containing the Time Machine backups failed, or what failed was trying to back up the new drive you added? If Time Machine was able to complete the first full backup of the new drive, then adding Time Machine didn't cause the problem, it was a coincidence. If Time Machine runs out of space it just starts deleting the oldest backup. I suppose it might fail on the first Time Machine run after the initial backup if it didn't have space to delete stuff. When you look at the Time Machine drive in the Finder, is it in fact full? If there's plenty of space left on it, it's not clear what the failure was about.
Also, testing and verifying with Disk Utility will spot some problems but not all.

Thunderbolt can be daisy-chained, so if it or other Thunderbolt devices have a pass-through port it might be possible to do all that. But it might be better to return the drive and get a USB 3 drive instead. It would be fast enough, cheaper, and more versatile. For a single hard drive (not a RAID or SSD), Thunderbolt is not really much faster than USB 3.

Can 'Time Machine' back-up other external hard drives

Can 'Time Machine' back-up other external hard drives connected to your mac as well as the mac memory itself?

As Neil says, yes, it can. But external HDs are excluded by default; you have to tell Time Machine when you do want to back one up.
See the exclusions box in Time Machine Prefs > Options.
If the drive is shown in black, just select it and click the minus sign at the bottom.
If it's shown in gray, though, it's not formatted for a Mac, and Time Machine can't back it up (and you can't remove it).

Can time machine be used to back up one external drive to another external drive?

I use the photography program Lightroom to organize and develop digital photos. All my photos are stored on my iMac internal drive. The internal drive is almost full so I want to move my photos to a new external drive. At present, I have an external drive devoted to backing up my iMac using time machine. I have no need to change this arrangement. I would like to use a new external drive to serve as the primary location for my pictures, which I will move from the internal drive. Then I would like to backup that drive to a third external back up drive. Can time machine be used to automatically back up the second drive to the third drive as well as for continuing to provide ongoing backups to my internal drive as it is currently doing?
Thank you in advance for your assistance.

Thanks for the links, but I don't see in the pondini links, the scenario I am asking about.
Time Machine can easily back up multiple internal and/or directly-connected external drives and partitions simultaneously (but Time Machine cannotback up data that's on a network).
From the first link.

... Please note that my iMac internal drive is backing up to external drive number 1 using time machine. I want my pictures on external drive two and those backed up to external drive three. So are you saying that if I have 500 GB of pictures on drive number 2, I will need a third drive that is at least 1 TB?
the confusion starts in your above statement...
There should be Only One Time Machine Drive.

Can I back up an external drive and an airbook with a third drive

I would like to back up an external drive and an airbook with a third drive. This was the setup I used with my Imac. The third drive was linked to the external drive which was linked to the imac. I used time machine. Both the third drive and the external drive were visible on the desktop of the imac. Now I want to use this system to back up the airbook and the external drive, but the third drive doesn't appear on the airbook's desk top, in fact it is invisible and doesn't seem to be recognized in finder or anywhere else from the airbook. Is there some distinction that prevents the airbook from allowing this back up configuration, but that allowed the imac to work in this configuration.
Thanks,
Daviiiiiiid

Of course, always that the external drive is formatted in “Mac OS Extended (Journaled)”. Apart from that, you shouldn't have any issue,
Then, open System Preferences > Time Machine > Options, and remove the external drive from excluded items. The next backup will include your external drive.
Note that you may not be able to back up the external drive if it's connected to your Time Capsule. If it doesn't work, connect the external drive to your computer

I have lost my Safari app and all the bookmarks that go with it. I have tried to download my back-up on external drive but cannot access it. Tried a start with C key held down but still no access to the back-up app.

Have used Superduper app. to back up and checked back-up occasionally to see if all files present and appeared OK.
I had previously started machine using original CD #1 to try and replace Eudora which was acting up. Did not knowingly touch Safari.
Running iMAC System 10.4.11
How can I successfully download from the Maxtor back-up?

Further info.
I checked the content of my other back-up and found the bookmark Bookmarks.plist in the library under Safari
Dumped the existing copy in the computer and drag-dropped the back up. All bookmarks restored.
Solved the Stickies problem by using Spotlight to find file "stickiesdatabase" and did a drag- drop to replace file. All data restored.
Re Ical data loss. Used Spotlight to find iCal document in Library - Preferences where I found com.apple.iCal.plist in folder.
Got ready to make change but did not immediately remove file. When I returned to Preferences folder to grab above document,
the readable descriptors had been changed to code consisting of some upper case letters and/or single symbols!
So now I cannot tell which is the symbol iCal.plist
Thanks for leading me so far, but how do I find that plist for my calendar?

How do I configure my timecapsule to back up an external drive connected to macbook?

How do I configure my timecapsule to back up an external drive connected to macbook?

First, insure that the external drive has been formatted in Mac OS Extended Journaled
If it's not, and you already have data on the drive, you will need to move that data to another temporary storage location....as the format to Mac OS Extended (Journaled) will erase everything on the drive. Once the drive has been formatted, move the data from the temporary storage location back to the external drive
Click the Time Machine clock icon at the top of the screen
Click Time Machine Preferences
Click Options
Click the name of the external drive to highlight it, and then click the - (minus) button at the bottom of the list to remove the drive from the list of "excluded" items for backup
The drive will now be backed up by Time Machine on the next and all subsequent backups

Cannot reinstate catalog after returning PC (Windows 7) to factory settings (because of worm infection). Catalog was backed up on external drive but not using PSE backup facility. Cannot find and *.tly file. Is this hopeless?

If you made backups of all of your photos and your catalog file using some third-party method (i.e. not using the PSE catalog backup command), then you should be able to restore everything.
Step 1. Put the photos in the EXACT SAME LOCATION as before. For example, if they were in subfolders of C:\Users\<username>\Documents, then they must go into the exact same subfolders of C:\Users\<username>\Documents.
Step 2. Move the catalog file to wherever you want it to be, and then double-click on it.

Back-up on external drive, in addition to the time machine external drive

Quick question: I am using Time machine on an external drive next to my laptop. To protect against fire/theft, I want to do a monthly back up on an other external drive which would be kept at work. Does time machine allow 2 external back up drives and remember what needs to be updated on each, or do I need to use SuperDuper or similar to do my monthly back up?

You can do what you want by going in to System Preferences > Time Machine > Change Disk whenever you rotate disks. Time Machine will keep track what modified files belong to its respective backups on the two disks. However, it's always a very good idea to diversify risk in your backups so using different software for your second set of backups would be something to seriously consider. SuperDuper is not yet Leopard compatible but Carbon Copy Cloner is. You can use the "Copy selected items" function in CCC to do incremental backups.

Backing up 1 external drive on to 2

Hi -- I have a 400 gb external hard drive that stores my Itunes library, with about 260 gb of music on it. I want to back it up on to a 250 gb drive and an 80 gb drive. Can anyone recommend software that handles this requirement well? (e.g., like pausing when the target disk is full) Do the Mac backup utilities do it?
Ideally, it would allow for an easy restore, if that is ever necessary. Thanks. -- David

You can't back up an external drive that is connected to a TC to the TC itself using Time Machine.

MacPro won't mount Windows USB3 External drive

I have a macPro 2,1 and it won't mount a Windows external drive that is USB3. I've tried NTFS-3G but still won't see the USB3 drive. I thought USB3 was backwards compatible. Can anyone help?

WEll, Paragon tends to have kept up their NTFS drivers
Your Mac is using PCIe 3.0 controller which are iffy even on OS X and may not be seen by Windows (and my Windows PCIe 3.0 card doesn't show up or work in Mac OS).
If you attach it via USB2 it might show, depends really on the bridge used by the enclosure probably. It is has USB3 and eSATA and you have PCIe SATA (Sonnet E4P is expensive but works great in both platforms)
