The backup was not performed because an error occurred while copying files

One Time Capsule, Two MacBook's, OS10.6.6
One MacBook can backup no problem, The other cannot backup says: the backup was not performed because an error occurred while copying files to the backup disk.
Using a Time Machine Buddy widget gives:

This could very well have to do with ACLs.
I bumped into the same problem:
5/8/11 10:43:22 PM com.apple.backupd[7126] Error: (-41) SrcErr:NO Copying /Users/SA/Public/Drop Box/HandBrake.app/Contents/Frameworks/Sparkle.framework/Versions/A/ Resources/de.lproj/SUAutomaticUpdateAlert.nib/classes.nib to /Volumes/Local Backup/Backups.backupdb/Server/2011-05-08-221524.inProgress/88ACE716-0660-44C8- A128-CF01046FC2F8/Macintosh HD/Users/SA/Public/Drop Box/HandBrake.app/Contents/Frameworks/Sparkle.framework/Versions/A/ Resources/de.lproj/SUAutomaticUpdateAlert.nib
Using DD or CCC is no option for me, I don't want downtime and I want incremental backups. So I started to investigate.
I repartitioned my external Time Machine drive, did the backup again. It didn't work. Then I blocked the culprit file mentioned in the logs from being backed up with TM. That helped, only to find that a bit later it found another file with issues.
So i looked at the files an found they had ACLs on them that somehow prevented them from being copied.
SOLUTION:
remove the ACL from the file.
If you want to remove all ACLs in a directory, use Terminal and navigate to that directory. Then issue this command:
sudo echo | sudo chmod -R -E ./*
If you would like to remove ACLs from a single file or package (e.g. an application), issue this:
sudo echo | sudo chmod -R -E <nameoffile>
You might have to this several times since there might be multiple files affected. Unlike previous solutions, this one does not require you to delete the file.
I got the command to remove ACLs from http://osxadmin.blogspot.com/2008/01/chmod-acl-removal.html

Mac Help says:
If you back up to a Time Capsule or network disk:
Open the Time Machine pane of System Preferences, and slide the switch to Off.
Open Time Machine preferences
Open Disk Utility, which is in the Utilities folder in the Applications folder.
Open Disk Utility
Make sure the Time Capsule or network disk is turned on and available.
Open a Finder window, select your Time Capsule or network disk in the Shared section of the sidebar, and click Connect. If necessary, enter your user name and password.
On the Time Capsule or network disk, select the disk or volume that contains Time Machine backups. Depending on how your Time Capsule is set up, there may be one or more disks or volumes.
Locate your backup, and drag it to the Disk Utility sidebar.You can identify your backup by looking for your computer’s name in the backup’s filename.

I followed #C3 and loaded Time Machine Buddy, which was defnitely helpful, then deleted the file that the backup failed at, but after 3 more attempts I stopped deleting or excluding files as this wasn't improving the situation.
The recommendation is to exclude those files from being backed-up, not to delete them!
Updating boot support partitions for the volume as required:
Yes, that's a bit misleading. It just means that will be done, if it's required, which it isn't on your backups.
I have no idea if anything actually was changed however just when I had given up and walked away, TM has started working after a week of failing.
It probably did find and fix something. Just for reference, Disk Utiltiy usually shows the progress and repair messages in the center part of the window, but often doesn't when repairing a sparse bundle on a network. You can see the messages at any time by clicking the Log icon in the toolbar, or select Window > Show Log from the menubar.
Anyway, glad it's sorted out!

What does this mean: "the backup was not performed because an error occurred while copying files to the backup disk?

Our time capsule isn't working...we keep getting the message: "The back up was not performed because an error occurred while copying files to the backup disk."

This means you are probably not running snow leopard as your profile shows.
What OS are you running?? Mavericks.. is the most likely as it has the most network bugs.
See Pondini.
http://pondini.org/TM/Troubleshooting.html
C3 .. but the error might have nothing to do with the real problem.. ie bad networking.
If your MBP has ethernet have you tried turning off wireless and attempting the backup by ethernet??
No luck give me more info.

Heeeelp!!!
MBP Lion, Back up using time machine to an external HD 1T Seagate connected by USB, plenty of space left. Everything worked well, until it didn't!
I can use Time machine to go back in time, and I can see/access/play movies from the library on the external HD. It all works except the backup. I have rebooted everything, I have verify'ed and 'repair disk teh HD several times, I have done the same to my Mactintosh HD + repair permissions. I was earlier getting a different error message and used time machine buddy to ID a file that was behaving, actually an old application that I have listed in options in time machine preferences to exclude. Note that there is also the name of the back up destination on this list but it is greyed out.
SMART status is 'not supported'.
Error now reads unable to complete back up, An error occured while creating the back up folder.

Does this mean that I list as an exception the back up volume? Is it trying to back up the back up?
Appreciate any advice thanks. Jamie

It's still a drive malfunction. The drive hasn't necessarily failed in the usual sense. Those drives just don't seem to work well with Time Machine. I don't know why, and I don't know why it worked until now.

I am receiving an error message: " the backup was not performed because an error occurred while copying files to the backup disk". I have used the Disk Utility tot "Repair Disk" and it appears that there are no problems with the back up file..
I continue to receive the error message. What can anyone suggest I do?

One of Apple's less-than-informative messages.
Most likely, there's a damaged file on your system; see #C3 in Time Machine - Troubleshooting. It will show you how to locate the message(s) that describe the problem, then help you fix it.

Not one of Apple's better messages.
If you haven't found it yet, see #C3 in Time Machine - Troubleshooting. TM is likely having a problem with a file, and that will show you how to find and fix it.

I keep getting this message: "The back up was not performed because an error occurred while copying files to the backup disk. The problem may be tempory. Try again later to back up. If the problem persists, use Disk Utility to repair your backup disk."

I've repeatedly "tried again" over the past month with no luck. I'd rather not delete everything if that's what "repairing" the back disk involves.

On a time capsule the error message is meaningless. That would only apply to an external drive...TC is a network drive.
I recommend you just reboot the whole network.. from off..
Restart in order.. modem.. TC.. clients. Wait 2 min between each one.
If the disk still won't mount give us more info..
Are you using wireless or ethernet?
How is the TC configured?
What sort of internet?

Time Machine Error: The backup was not performed because an error occurred

G'day (from Queensland, Australia)
Not for the first time Time Machine has broken down - originally in September 08 (I just can't recall how I fixed it!!).
Now it has failed after 14 months of faultless performance.

So, using Finder, I opened my Time Capsule and renamed "xxxxxx’s iMac_00224135e6fb.sparsebundle" as "091222xxxxxx’s iMac_00224135e6fb.sparsebundle091222"

Time Machine: Backup was not performed because an error occurred...

I have tried 4-5 different USB/Firewire backup disks. None work.
I keep getting the message "The backup was not performed because an error occurred while copying files to the backup disk."
Any ideas?

I started to get the same error about a week ago... thought my 4 year old 1TB firewire WD was finally dead... bought a 3TB one to replace it over the weekend. Well, still had the error... found this post... and sure enough, deep within one of my development websites a folder had some crazy permissions.
Changed those and TimeMachine is back to normal.

Can anyone help me?Time Machine couldn't complete the backup to... An error occurred while copying files. The problem may be temporary. If the problem persists, use Disk Utility to repair your backup disk. What is the problem? I've made no changes.

I recently starting receiving the error message "Time Machine couldn't complete the backup to... An erro occurred while copying files. The problem may be temporary. If the problem persists, use Disk Utility to repair your backup disk. I have had no problems backing up my MacBook Pro 2011 to my Western Digital My Book Live through a Linksys EA4500 router until recently. I've made no major changes. I've ran a diagnosis on my back up drive with no problems. The Time Machine back up starts, but about after about 5 to 10 minutes I get the error message. I can see the shared drive in Finder. The light on the drive blinks while it starts the back up. I can see the shared folders on the networked drive. The backup process starts but for some reason it just stops. Can anyone help?

You can't repair a network volume in Disk Utility.
Backing up to a third-party NAS with Time Machine is risky, and unacceptably risky if it's your only backup. I know this isn't the answer you want, and I also know that the manufacturer says the device will work with Time Machine, and that it usually seems to work. Except when you try to restore, and find that you can't.
If you want network backup with Time Machine, use as the destination either an Apple Time Capsule or an external hard drive connected to another Mac or to an 802.11ac AirPort base station. Only the 802.11ac base stations support Time Machine, not any older model.
If you're determined to keep using the NAS for backup, your only recourse for any problems that result is to the manufacturer (which will blame Apple.)

I tried going back to the gmail settings to ensure the trash settings were set to SHOW and SHOW IN IMAP, and I unchecked "Store deleted messages on the server" for the gmail account in the mail.app, as I was also getting messages about not being able to move messages to trash(null), and I thought that might be the issue, but while that fixed the mail issue, it did not fix the Time Machine issue.
Any help with this would be greatly appreciated.

The TC in and of itself is running ok.. otherwise you would not have internet.. so the issue is the OS in the computer.. however the combo is worse than the sum of the parts.. ie Somehow TC is less reliable with Yosemite than it would otherwise be..
here is the normal fix list.. but it is far from foolproof.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
ie Start from a factory reset. No files are lost on the hard disk doing this.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 and TCwifi for basestation and wireless respectively.
Even better if the issue is more wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round.
2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking. If the TC is main router it will not be an issue.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the laptop itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Tell us how you go.
Someone posted a solution.. See this thread.

Time Machine will not complete a system backup and terminates with "Unable to complete backup. An error occurred while copying files to the backup volume. This follows a problem when Time machne terminated when the volume was almost full.

On 11/1/2011, Time Machine (TM) terminated with an error message I did not record. I noted that the drive was full and decided to do a separate complete bootable system backup using Carbon Copy Clone (CCC), before clearing the TM volume and trying to start it over clean. Part way through the full system backup CCC put up a message that there was a Physical Problem "Library/Application Support/Techtool Protection/McIntosh HD/Directory Backup 2011-11-01-16-28-16". That was about the time that TM malfunctioned, so I assumed they were related. After starting CCC over a couple of times, and getting the same error message, I let it go through to completion of the backup, which took three or four hours. I then ran tests using Disk Utility and verified that there was nothing physically wrong with both the internal hard drive and the TM volume. I also erased and reformatted the TM volume. However, every time I started Time Machine, it would record a few GB and terminate with "Unable to complete backup. An error occurred while copying files to the backup volume". I restarted the computer with no change in results. Note that prior to starting the CCC backup, I "Repaired Permissions", "zapped the PRAM" and "re-set the SMC", hoping to have a clean bootable system on the backup. I ran Techtool and no problems were found.
I'm running this on an Intel iMac under 10.5.8 and recording to a 500GB My Passport drive. My hard drive is only about half full at 246 GB. My assessment is that something happened at 16-28-16 on 11/1/2001 to screwup the Backup Directory in the file at "Library/Application Support/Techtool Protection/McIntosh HD/Directory Backup 2011-11-01-16-28-16". My question is, how do I fix it?
I had just completed writing everything above here, explaining the problems I had been encountering for the past 24 hours. I had the Time Machine window standing open on the desktop where I could see it, having recentlycleared it after the last termination. As I was proofing what I had written, I looked at the window and noted that the clock had started a new run for a full back up, since all prior efforts had failed and the TM volume was empty. As I watched and waited for it to fail again, as it had been doing at about 13 GB, it kept going and going until it just finished a complete backup, about 4.5 hours later, with my having done nothing. Now my question would have to be - what could possiibly have happened to make it perform this way? It will be interesting to see if it continue to operate normally, or if the problem will return, in a later backup run.

You should not keep those files for long, and probably shouldn't back them up (if you need them at all -- since you do regular backups, I'm doubtful just how worthwhile that feature is).
"Unable to complete backup. An error occurred while copying files to the backup volume".
One of Apple's maddeningly incomplete messages. Most likely, there's a problem with a file (quite possibly the one CCC didn't like). See #C3 in Time Machine - Troubleshooting for details and instructions on finding and fixing it.
If you continue running the Directory Protection app, be sure to exclude your Time Machine drive from it (as it will just take up lots of room, and won't help repair your backups if there's a problem); and exclude the folders it creates from being backed-up by Time Machine (as they'll create large backups, and you probably can't use the backed-up folders anyway), per #10 in Time Machine - Frequently Asked Questions.

The backup was not performed because an error occurred while copying files
