Time Machine Error. Unable to complete backup. An error occurred while copy

For what it's worth, I recently connected a Western Digital MyBook (FireWire) and had to update its firmware and drivers to get it to behave. Now all's well.

If you haven't done that, check out WD's web site.

Thanks for the big hint... I am having this problem and so looked in my system.log (open Utilities/Console and look for messages from backupd. In the
Here, you can see the copy failed on the .DS_Store for my Desktop. That can just be deleted; I'm hoping it will run to completion next time.

I would be interested to hear if after deleting this file your backup completed normally.

I guess I forgot to say! Yes, it did complete successfully.

I updated to 10.5.3 the 1st day it was available. Today, I got the Time Machine error:



“Unable to complete backup

An error occurred while copying files to backup volume.”



I tried a manual “back up now” & got the same error within 1 minute.



I’ve had my iMac & my 500 GB LaCie backup HDD for 6 months & backup has worked perfectly until today.



I read many posts about this. My LaCie has not just reached ~ 10 GB, it has ~ 84+ GB of data. Nothing on it except the Time Machine backup. I checked my Console & nothing listed about back up. Only had 3 things listed & no errors listed? Maybe I needed to do something other than simply opening console? I did see the red dot when going to Time Machine Preferences & could click on the red dot to again see that error message.



I rebooted, tried manual backup again & it worked!



I have no idea what the problem is & this “solution” will most likely work for very few of those with the problem as rebooting was probably tried by others without success.



FWIW



Good luck.



I guess Macs don't always “just work.”

I've had this happen a couple more times, and, yes, it's disappointing.

I'm beginning to think that this happens because Time Machine is trying to backup a file being accessed at the same moment. It would be nice if Time Machine would just skip the file and try it again after the rest of the backup completed or simply wait a second or two and try the file again.

The reason I think this is that when the backup runs again, it just works, so this appears to be transient.

For now, I think, just tell Time Machine to "backup now" and see if the error just disappears. If it doesn't, you'll have to look in the console logs...

To check the logs:
1. Start up Console (should be in Applications/Utilities).
2. Click "Show Log List" on top left if necessary.
3. Click "system.log" just under "LOG FILES" in the log list.
4. Type "backupd" in the filter box at the top right.

Look for an error near the bottom to find out what happened; it might help to make the window really wide. It should include the file that caused the problem. Then, you just have to figure out what you want to do with that file... No fun, I know; hopefully, the backup will just work most times on the second try.

Hope this helps!

Hi Liz,



So far backup running hourly w/o problems. I opened Console & now it has a huge amount of stuff. 920 messages! I clicked “Show Log List” &"system.log"; just under "LOG FILES" in the log list.



I typed "backupd" in the filter search box at the top right & have a long list with “Backups.backupdb” (Should I have added a “b” after the “d” in the filter box?) I tried & got a much shorter list. In any event all the entries are dated 6-3-2008 & my problem happened on 6-1-2008.



I wonder if the logs are erased every 24 hours?



I just tried using Time Machine to see if I could look at the console logs as they appeared on 6-1-208 but console didn't open, just a window about console, version etc.

I have had this problem 3 times since updating to 10.5.3. It must be a known issue by now by Apple. I will file a bug report on it.
Rebooting allowed me to make a backup as you discovered.
However, the 3rd time it happened, I closed my mail.app and I could make a manual backup without booting, so I believe the issue with TM may be related to the mail "fix" it contained, or it may be that TM has a problem with open files.
If you get the error, try closing all open apps and then seeing if a manual "backup now" works. If it does, it makes my case that the error is related to open files.

I just got same error!
Check logs shows:

And then, next backup--problem!

I closed all programs & tried manual backup. It worked. I don’t know why.

I get this same error message and this has happened five times since I upgraded to 10.5.3. The error message says, "backup failed with error: target volume is read-only". The console says,"Macintosh /System/Library/CoreServices/backupd[196]. Not sure why this continues. Have a lot of room remaining on the Maxtor 260 external HD. Any idea's??

I still can't get this to work following everyone's advice. However, I noticed that I have no problem with my Mac Pro, which is on a wired connection only. My MacBook Pro is having a problem and it is only using wireless. What are you backing up over?

WIred connection.

I get this problem about 1x/day. I tried doing nothing & later a backup succeeded.

I keep getting the Time Machine backup error too, like many others. Was fine until just the other day, now, nothing. Although my husband's backs up just fine. I assume it's the 10.5.3 bug everyone else has. I've tried reselecting the drive, running the disk utility, shutting everything on and off... help!
Here's the console log- anyone know what this means?

I have had just a few backup failures since starting with Time Machine last December. Since I recently updated to 10.5.3, I decided to check into a recent failure.

Searching Console's All Messages log for "backupd" found this error:

6/10/08 10:37:54 AM /System/Library/CoreServices/backupd[59811] Error: (-43) copying /Users/ward/Develop/ administrivia/.DS_Store to ...

I'm doubly puzzled:

1. Why did Time Machine think it needed to backup this file? The .DS_Store file holds attributes of the "administrivia" folder, which I have not touched since I first started using Time Machine.

2. Why did Time Machine get a "file not found" error (-43)? I just opened the folder, and Finder had remembered the folder window size, position and list format.

I kicked off a manual backup, which worked fine.

I'll be watching Time Machine more carefully.
