Time machine has stopped working

The availability of the command depends on the OSX version. Is that what you are alluding to, or, are you referring to the filesystem ACL Control utility itself?

The OP has yet to mention the version of OSX they are running, correct? I am not sure where this sidebar discussion going. Is this a risk to the filesystem? Yes, of course it is.

No, not correct. This is the Mavericks forum. What happens when you run "fsaclctl" in Mavericks? If it's not what you thought, why did you advise the OP to do it?

OP has not been asked to execute anything but provide screen shots for validation, and is being provided reading material. You have objections to such material being provided to educate the OP? 😕. Should I need to re-quote my response, that I have done twice already? I have also seen the screen shot which shows a Mavericks splash screen.

Do you know for a fact that this USB device is not being used as a Time Machine backup across multiple OSes? Has the OP stated any such piece of information? For all we know, he could be using more than one OS for this device, correct?

I sense a confrontational attitude, am I right, Linc? If that is the case, please say so, and I have no desire or need for it. If you think you can help the OP, please do so by all means.

Your backup starts and aborts leaving the .inProgress file because there is an issue with the source file(s) it is trying to copy. The error code 11 is a Unix error code called EAGAIN (which has this cryptic explanation - "Try again..."). The challenge is to find what is incorrect and what the source is.

There is a Dashboard widget called Time Machine Buddy available here - http://www.apple.com/downloads/dashboard/status/timemachinebuddy.html

I downloaded it and it is a log reader/consolidator which looks in your Console logs to look for TM related messages and consolidates them in a widget.

My recommendation is download it, install it, and execute it from the Dashboard. You can then look at the output (Click on the arrow next to Message to expand the individual entries). It should tell you why it aborted. It could be a bad file name, it could be bad permissions (which are fixable to some extent via Disk Utility). The widget does not make any changes except installing itself.

Here is an example of the error message on my rMBP.

Failed to resolve network service using name = TCn5 type = _afpovertcp._tcp domain = local.

Backup failed with error 18: The backup disk could not be found.

If this does not resolve it, then the needle-in-haystack search needs to be resumed.

Looking in the package may not provide that much information.

Reference - http://pondini.org/OSX/Logs.html

There is an old error in Time Machine software with an apostrophe in the machine name 'Bevan's iMac' which used to cause problems. If you have the old TM drive, you can see if this file/directory exists in the backup.

/System/Library/PrivateFrameworks/WebKit2.framework/Versions/A/XPCServices/com.a pple.WebKit.Plugin.64.xpc

Was your iMac's name different when it last worked correctly? You can try changing your machine name and check if the backup generates the same error. If this is a new drive that has never had a successful backup, you can also initialize the disk and set it up as a backup disk.

In my case, I do not have an apostrophe in my machine name, because I have had issues in the past with the machine name. I make all my machine names with the dash character, if needed, and without any spaces.

From what you have posted I cannot discern if the 'Macintos h HD' has a hidden control character or it is just the way it has been formatted.

Also error -48 says there is a duplicate filename when a rename (mv) is attempted. The second error, -8062, is related to the previous error because the parent directory that contains the file does not exist due to error -48. See the output of ls -lR following the two error codes.

macerror -48

Mac OS error -48 (dupFNErr): duplicate filename (rename)

macerror -8062

Unknown error (-8062) at /usr/bin/macerror5.16 line 40, <DATA> line 1.
