Time Machine backup failed on MacBook

Asked By anonymous 7060 points N/A Posted on - 11/16/2011

Hi everyone,

I need help about this Recently I got my new MacBook Pro, 2.4GHz dual-core, Intel Core i5, 4 GB 1333 MHz. Since I am an active user of Mac I never had an experience like this. For backup files I am using Time Machine. All backups I store on external hard drive.

Now I wanted to do the same thing with the data that I have. On this new MacBook when I was near the end I got an error message and back up was terminated. I am a little bit confused, when I try it again I got the same error.

Time Machine Error

Unable to complete backup. An error occurred while

copying files to the backup volume

                                                              Ok

What should I do?

Time Machine backup failed on MacBook

Hi Anonymous,

It is a rule of thumb that regardless of the specific issue, you should first make sure your software is up-to-date. Now, if you use Time Machine with Time Capsule, make sure you have updated your Time Capsule with the latest available software and firmware.

By the way, if you are able to give me a screenshot of the exact error message that would help a lot. (Shift + Command + 4).

The closest answer that I have found, since I'm not sure exactly what the error is, this:

Red "i" message: "Time Machine could not be configured. The built-in network interface could not be found"

1. From the Finder's Go menu go to this location: /Library/Preferences/SystemConfiguration/  

2. Copy the file "NetworkInterfaces.plist" to the desktop (to make a precautionary backup).

3. Delete the file "NetworkInterfaces.plist". Enter an administrator name and password if prompted.

4. Restart your Mac.

5. Once restarted, reconfigure your Network and Time Machine preference panes in System Preferences.

6. If the issue persists, contact an Apple Authorized Service Provider to have your Mac's network ports checked.

Hope this helps,
