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.

Time Machine won't back up to External

Would appreciate some guidance please.
Have been running Time Machine since August ( when bought iMac 21.5 ) without any problem.
I installed a 2nd ( portable ) external hard drive that I back up to separately. I'd been under the impression that I had excluded this 2nd hd from the TM options but had'nt and now done so.
Up until a few hours ago TM was ok but now get a message saying " Files can't be copied onto the backup because it appears to be read only" that prompted me to check if TM was also backing up the other hd which it was but did'nt want it to.
My internal hd is 500gb though only 70 gb is currently used. TM is being backed up to a 320gb external hd which I know is too small and should be 2-3tb but as I've only used 70gb I thought 320 would suffice for the time being. TM is now saying that there is only 94gb free left on it's external but been under the impression that once the hd becomes full, TM starts delete the old(er) files.
In TM options I now have the 2nd portable external hard drive ( 37gb used) excluded though the TM hard drive is shown but greyed out.
The ' won't back up essage ' also has a further note about using disk repair but would I then risk losing all the TM backup data?
OSX is 10.8.2 and up until now it's bee running perfect. Grateful for any pointers.
Thanks John

The backup drive has malfunctioned and corrupted itself. If that has ever happened before, or if it ever happens again, replace the drive. You may want to consider replacing it anyway for the safety of your data.
If you choose to keep using the drive, disable Time Machine temporarily in its preference pane, then launch Disk Utility, select the backup volume, and run Repair Disk. This operation may take several hours. If the volume can't be repaired, you'll have to erase it and start over. Don't do that unless you have at least one other complete backup. You should start another backup now if you don't already have one. One backup is not enough to be safe.

Time machine won't back up my music drive

When I use time machine to back up my music my external drive with my music on it called "music" won't back up. When I attempt to re add it to the items to be backed up, from the "Exclude these items from backups", in the time machine preferences, it at first moves over to the items to be backed up, but when I exit the preferences and reopen it the music external drive shows up again as an excluded item. I've even named two drives music and neither will time machine allow me to back up. In the past I've successfully backed it up but can't now.

See C10 in the first linked article.

How can I keep Time Machine from Automatically backing up any external drive connected

Problem: Whenever I have an external drive attached and TimeMachine starts, it tries to back-up the drive. Usually, this causes Time Machine to gut my TimeMachine back-ups to try and make room before saying, not enough space to complete the back-up. NOT Helpful! I maintain offline/offsite clones of my drives but I also receive drives with large amounts of data which I will want backed up AFTER I have copied it to my drives. Yes, I can go into TimeMachine and exclude the drive(s). If I forget to do that, then BYE BYE back-ups.
Ideally, I would like a prompt asking if I want to include the drive in theTimeMachine back-up after I connect it. Anyone know how to set this?
or
I would be fine with simply having TimeMachine treat all drives unknown to the backup as drives to be ignored.
Thoughts?

It worked beautifully before and would update only when I plugged the firewire drive in and also if I left it over 10 days it would remind me to back up the computer.
Right, the behavior hasn't changed between SL and Lion.
I would have liked the option to set times / days when I wanted.
SL didn't have this, any more than Lion does.
Also now I have a greyed out icon with a warning sign and clicking on the preferences it helpfully tells me the last back up has failed.
Because it DID.
I am usually happy with the updates and tweaks but this is one I am not happy and would appreciate a solution or at least a work around.... and no I don't like having the default to Time Machine as off!
Time Machine hasn't significantly changed between SL and Lion. Well, other than the local HD backup sets when a portable device is away from the actual backup destination, which really seem to freak people out for some reason.

Time Machine won't back up to internal Drive through AFP?

Hi All!
Heres my Problem.
I have a Mac Pro system with 4 Hard Drives installed inside the internal Bays. I wish to use one for Time Machine for the Clients.
On the clients i get the error about it not having the correct AFP version. (I know this is a common problem within Lion).
Although surely if the hard drive is inside a Mac Pro Server running Lion then the client should be able to back up through it to its INTERNAL drive.
Or does this still count as NAS?
Thoughts?
Dan

We are going to need more information from you in order to help.
What kind of hard drive is this?
How is it formatted?
Where is it connected? Directly to your Mac?
How is it connected? USB? Firewire?
What have you tried so far?
What error messages have you received?

Time machine does not back up to external drive

I plug in my hard drive and it is working..click "back up now" and it starts, but stops within a few seconds??????

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
Select "system.log" from the file list. Enter "backupd" (without the quotes) in the Filter text field. Post the messages from the last backup, beginning with "Starting standard backup." Post the log text, please, not a screenshot. Edit out excessive repeats, if any. Some personal information, such as the names of your files, may be included – edit that out, too, but don’t remove the context.

Time Machine won't back up external drive to Time Capsule

I recently got a Time Capsule, and successfully set it up to back up my iMac's primary drive, but for some reason Time Machine won't back up my external drive to the Time Capsule.
I removed the external drive from the exclusion list in System Preferences > Time Machine > Options, and from what I've read this should be sufficient to make Time Machine back up the drive.
The external drive is connected to my iMac via Thunderbolt > Thunderbolt-to-Firewire adaptor > Firewire 800 input, and the Time Capsule is connected via Ethernet to my LAN.
Since I'm using Ethernet, I've disabled Wi-Fi on the Time Capusule by going to AirPort Utility > My Time Capsule > Edit > Wireless > Network Mode > Off.
The reason I believe the external drive is not being backed up is because when I click the Time Machine icon in the upper-right status bar and choose "Enter Time Machine", none of the folders on external drive show any older versions.
Furthermore, when I click Finder > Time Machine Backups > Backups.backupdb, I can see only one sub-folder which has the name of my iMac's primary drive. I can't see any equivalent folder for my external drive.
Any idea what I'm doing wrong?

I don't see anything you have done wrong.. perhaps it does backup in a different way.
Load the widget.. A1 here... http://pondini.org/TM/Troubleshooting.html
That will allow you to track the log of TM to see what it is doing.
I would also try rebooting the computer.. exclude the drive again.. reboot.. and remove the exclusion.
You should be able to check the actual settings of TM in plist file.
And you can do a full reset of TM as well.. See A4. Check what is in the file. Pondini lists the location for you.
Nothing surprises me with Mountain Lion ...!!

Time Machine won't back up after system restore

I just restored my system after a failure, and now Time Machine won't back up my hard drive. It gets about 40 out of 90 Gigabytes done, and then gives me an error message that just says that there was an error while backing up, and doesn't give any other information. I ran a Verify Disk with Disk Utility, and there is nothing wrong with the backup drive, and there is more than 200 Gigabytes of space left on that drive.
Thank You.

Ok, so here's the thing: I tried backing up again today, and it worked just fine. Before, what would happen is a message would pop saying "an error has occurred during backup" (or something close to that). The point is, the message didn't give any detail.
No, the point is, you seem to have ignored this:

Time MAchine won't back up due to not enough space, but there is

TIme Machine won't back up. Displays this:
Actual capacity of the external backup drive is 999.68 GB and available is 135 gb .
The imac internal HD capacity is 999.01GB and used space is 636.321 GB.
This problem has occured periodically in the last 12 months or so, so prior to OS version10.8 install in Jul 2012.
I previously called AppleCare, as I have a contract, and tech said I just need to reformat the external drive and start over.
I did that the last time this happened a few months ago, but I don't like that option, as it eliminates all the prior backups,
What if I needed to try to recover something I deleted 3 weeks ago, for example. I couldn't do so as all backups would have been deleted, of course, by me having refomatted the drive and basically starting over. Also, I noted in another post about a person having a problem due to using a partitioned drive. Mine is not partition, as far as I can tell. See this:
Any ideas? Thanks

The solution is essentially "simple." You need a larger hard drive for these backups or you need to use a different backup solution. By this I mean using backup software that does not preserve an archive of old copies of a file, but simply erases old copies in order to replace them with the new copies. By replacing your backup drive can always accommodate the drive it backs up if it is large enough - say the same size. I can suggest:
Backup Software Recommendations
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
Synk Pro
Tri-Backup
Others may be found at VersionTracker or MacUpdate.
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files.
All of the above are capable of being scheduled. Synk Pro makes immediate backups of any changed file on the hard drive. You may configure it to archive changes (like Time Machine) or to delete prior copies.

Time Machine won't back up onto Time Capsule

I upgraded to Mountain Lion last week, and Time Machine won't back up to my Time Capsule. When it fails, I get the message:
Time Machine couldn't complete the backup to "Tom's Time Capsule".
The backup disk image "/Volumes/Data/TomsMac.sparsebundle" could not be created (error 60)
I sometimes get the same message, but with "error 17"
I also get the following error message popup (even though the disk is the one in my Time Capsule):
The disk you inserted was not readable by this computer.
The popup offers three choices: Initialize, Ignore, Eject.
My local Apple Store Genius concluded that the problem must be with the Time Capsule, so I bought a new one. That didn't fix the problem.
Time Machine Buddy messages:

I did Repair Disk Permissions and Verify Disk and everything's OK.
I erased the Time Capsule using AirPort Utility and did a hard reset on the Time Capsule.
I did a re-install of Mountain Lion and that didn't fix anything.
My MacBook Pro is accessing the Time Capsule wirelessly, as it always has.
Help!

Just to be sure, we're talking about a Time Capsule -- not an AirPort Extreme connected to an external hard drive. Right?
If so, proceed as follows.
Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Time Machine won't back-up. Why?

Time Machine won't back-up to LaCie external drive (OS 10.7.4) after I disconnected and reconnected for a road trip.
Why? How can I correct?

After installing Mountain Lion, my Time Machine won't back up ... says the sparsebundle is in use

Standard problem in ML.. apple do not seem to want to recognise.
Reboot the TC .. if that fails restart the whole network in correct order.. modem.. router/TC... clients.. with 2min gap.
There are other suggestions like changing the password.. all they do is the same as reboot.
Read C12.. most quoted Q in pondini website history. This is asked 10 times a day.
http://pondini.org/TM/FAQ.html
Here is another way to get a useful utility in ML.. rather than toyland version.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall 6.1 so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool.

HT201250 Can I restore photo files from Time Machine without the use of an external drive? I'm trying to restore lost photo files and I see them listed in Time Machine (without use of an external drive), but when I try to restore I get a error code 36.

Can I restore photo files from Time Machine without the use of an external drive? While I was transferring photos back and forth from a thumb drive something went haywire and my IPhoto was wiped clean! When I click on Time Machine I see all the dated pages (without an external storage drive connected), go back to a date where all my photo files are there, click "restore", and I get the message: "The Finder can't complete the operation because some data in file cant be read or written (error code - 36)"

Thanks so much Terence. I tried some of the fixes from that page, but then discovered the suggestion to compress the Time Machine Back up of the original library and transfer it as a zip back to my computer as detailed here:
http://pondini.org/TM/E9.html
That worked like a charm. I really appreciate it.
