TM Stopped backing up another external drive

I have my photo library on a second external drive. It is operating fine...importing photos. TM is backing up my computer HD but not the external. Looking at the history it has been awhile since it backed it up properly.
It is not excluded in the setup
I just asked tm to perform a backup and put a test folder in the external drive. did not back up to the TM drive
what do I do?????

OK....I think it is working fine. I am a little confused however. If I am at my desktop and click on "enter TM" I get the TM backup for the desktop. If I click on my Photo-External drive and click on "enter TM" I get the TM backup for the photo drive.
that's how it should be.
My question is, if my photo external drive fails, how would I access the information? The icon for the drive won't be there if it fails
yes, but you still can access the backups. enter commandshiftc in finder and click on TM in the dock. scroll back in time. even if the original external is not present you will see its backups as a folder when you do this. you can restore anything you want from it. select what you want to restore, click on the "gears" action button in Finder's toolbar and select "restore to...".
Another option is to get a new drive and name it the same as the old one. then you can scroll back in it using regular TM interface and restore what you want normally.
thanks and sorry this is a bit of a dumb Q.

How do I move a back up to another external drive and how does the Mac Book then find the new back up?

how do I move a back up to another external drive and how does the Mac Book then find the new back up?
I currently have the back up on a Time Capsule, I want to move it from the Time Capsule to another external hard drive.

Did you read the link to the Pondidni website? You will have to select the Time Machine HDD for the new MBP and the old one in System Preferences>Time Machine:

Hello. I keep my IPhoto library (about 90GB) on an external HD and am trying to back it up to another external drive. Both are formatted Mac OS Extended (Case-sensitive, Journaled). Recently, backup has failed from the start due to error 36. Howtoresolve?

Hello. I keep my iPhoto library (about 90GB) on an external HD and am trying to back it up to another external drive. Both are formatted Mac OS Extended (Case-sensitive, Journaled) and both check out when scanned with Disk Utility. Recently, backup has failed from the start due to error 36. Any ideas how to resolve? Also, what's the maximum recommended size for an iPhoto library file? Thx!

Since you can't drag the library to the other EHD for the backup see if you can duplicate it (if you have enough room on the drive) by selecting it and typing Command+d (duplicate).
If you do rebuild the library without a backup and it goes awry you won't lose your photos but you may lose your orgnaizational efforts. So try the following:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library in the location of your choosing based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
NOTE: Fix 2 above might be the method you might want to try first with iPLM creating the new library on your second EHD. If it works that would get your backup copy on the second EHD at the same time as repairing it. If it does'nt work then go back to Fix 1.

Back up external drive to ANOTHER external drive

Is there a way to back up an external drive, automatically? I'd like to keep my Aperture masters on an external (preferably NAS) drive, and then back it up to a separate external drive. Haven't found a solution for this yet!
Reason I need to do this is I have 1T of photo's and 500GB HD on my laptop!

Youre endangering your valuable data by assuming its ever safe on ANY single place, especially the internal HD.
Grab a 1TB HD for $65 and offload/copy your photos to another HD.
You dont need superduper to copy ONE external HD to another......just connect both and drag and drop what or all to the new HD.
Superduper will do the same with just 2 clicks if you want, its free.

Backing up iTunes located on external drive to another external drive

Greetings,
I'm on iTuens 11.3 and in preferences have chosen an external drive to keep all my music. I would like to back-up the contents of my iTunes to another external drive.
I have NOT chosen: iTunes - File - Library - Organize Library
Perhaps this is my problem…?
The external hard drive that has my iTunes library does not have a single iTunes folder. Instead, each artist has a folder within which are multiple albums, single albums or songs.
It seems there should be a single file folder somewhere that I can copy to another external hard rive in order to make a back up.
Any help will be much appreciated.

There will only be a single folder if you've told iTunes to organize your library. You need to either do this, or drag all of the individual folders to the second drive, or clone the first drive to the second.
If desired, you can move the iTunes folder to the first drive, launch iTunes with the Option key held down, and choose it before organizing the library.

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.

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

How to transfer backup from another external drive

Have a LaCie making clicking sounds ...about to go. Should I transfer my docs to a disk before buying the Time Capsule ? How do you transfer info to the Time Capsule?

Transfer any documents you have immediately back to your Mac.. if they are not just backups..
If you don't have space then yes, get another external drive.
The TC is for TM backups.. if you mix backups and data on it, can lead to issues.. also the TC is not designed to store files.. we recommend against it.
The info is here though.
http://pondini.org/TM/TCQ3.html
The TC is just a network drive if you copy to it, just standard copy and paste via finder.

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?

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.

I went back to my external drive, trying to open the folder (containing the pictures I was working on), an icon "Thumbs" came up.

Elements 12, trouble restoring the catalogue from an external drive on my new Mac to another external drive - catalog too big for Mac HD.

I have completed a backup onto an external drive using Elements 12 on my PC running Windows XP. I am now trying to restore this backup onto my new Mac using another external drive as the destination as the catalog is too big to fit onto the Mac internal HD. All seems OK until I click the restore button then I get an error message "The Disc Drive in Mac HD does not contain a valid backup" The file names on the backup drive are visible on the Mac so I presume this backup must be valid so why is there a reference to the Mac HD?

System Preferences - Sharing. If you cannot find System Preferences, then use Command - Spacebar and type System Preference and when you see it in Spotlight (uper right) hit return.

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.

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.

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.
