An error occurred while copying files to the backup volume.

Hi,
after weeks of flawless operation,TimeMachine reports the following problem:

This failure might have been caused by putting my MacBook to sleep during the backup?
Forcing other backups results in a slightly different logs, like:

Is this problem known? I couldn't find any thread describing exactly this problem. Thanks.

3flyingdog,
Spotlight is having trouble indexing what Time Machine wants to backup. The problem may be the source files on your Mac as opposed to any actual Time Machine problems.
First, use Disk Utility to repair permission on your Macs internal hard disk. Then try backing up again.
Next, failing that, boot from your Macs original install DVDs and go to the Utilities menu and launch Disk Utility and "Verify" your Macs internal hard disk. If problems are found "Repair" them. Then try backing up again.
Otherwise, use Disk Utility on the external backup drive and see if that needs repair.
Cheers!

  • 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.

    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.
    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Enter the word "Starting" (without the quotes) in the String Matching text field. You should now see log messages with the words "Starting * backup," where * represents any of the words "automatic," "manual," or "standard." Note the timestamp of the last such message that corresponds to a failed backup. Now
    CLEAR THE WORD "Starting" FROM THE TEXT FIELD
    so that all messages are showning, and scroll back in the log to the time you noted. Select the messages timestamped from then until the end of the backup, or the end of the log if that's not clear. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.
    If all you see are messages that contain the word "Starting," you didn't clear the text field.
    If there are runs of repeated messages, post only one example of each. Don't post many repetitions of the same message.
    When posting a log extract, be selective. Don't post more than is requested.

  • HT3275 Time Machine error. Unable to complete backup. An error occurred while copying files to the backup volume. Tried restarting, remounting external WD drive. Still cannot backup.

    Time Machine quit backing up files. Bought a new WD external drive. Worked for awhile, then quit backing up. Tried restarting computer, remounting drive. Message: Time Machine Error. Unable to complete backup. An error occurred when copying files. Suggestions?

    Thanks so very much for your help!! I'm boggled by it and now just about ready to dump the whole idea of Time Machine and backup using a cloning program. Maybe TM is only guaranteed to work well with Time Capsule these days?
    Today there again was no backup. I did as you suggested, looked into Console. It showed many lines of "(Error) DiskStore: No block in wakeup" and also repeatedly "(Warning) DiskStore: Ignored bogus fetch...".
    So I created a marker and attempted to initiate a backup, keeping Console open and refreshed. Here's what I got:

    I'm thinking it's the standalone Buffalo backup drive not waking up, and so everything comes to a screeching halt. Do you also think I should abandon TM and just do manual backups every day using a clone program?

  • "Unable to complete backup. An error occurred while copying files to the backup volume."

    I get this message when I try to use time machine to backup my files to an external disk. I tried the restart route, and still same problem. Anyone have any ideas?

    Actually this is what is listed after "Starting standard backup". I editted out personal names.

  • HT3275 "Unable to complete backup. An error occurred while copying files to the backup volume."

    I'm running Mountain Lion on a Mac Pro with Time Machine backing up to an exterior volume composed of four 3TB drives.  System and TM have been working fine until now.  Disk Utility reports the backup drive is fine.  I've restarted and run TM again and keep having the same problem.  I recently swapped out one of my internal drives for a larger drive, which is working fine but that is when TM started acting up.  Any suggestions?

    http://pondini.org/TM/B5.html
    Pondini's site was out of action but back up now.
    A new internal drive has a new UUID.. and should be treated by TM as a new computer. But you can inherit the old backup.. if you have restored to the drive then it hopefully will work but as you say take many hours.
    I think it is better to start over.. but up to you.

  • HT3275 This help article says Red "i" message: "Unable to complete backup. An error occurred while copying files to the backup volume."  Restart, then try the backup once again."  OK, I've done that a few times and still receive the same error message. No

    My Time Machine backup is repeatedly failing -- instead I receive a message saying it's unable to complete backup because an error has occured.  The only "Help" advice is to restart the computer and try to back up again, but that did not solve the problem. Help, please?

    Restart the whole network.. not just the computer.. restart in correct order with everything off.
    modem
    TC or router
    clients
    2min gap.
    If you still have trouble, give us the whole network layout.. what broadband? what modem? any other router? are you using wireless? what mode is the TC in?
    I am assuming you are using a time capsule.

  • My time machine says unable to complete backup. An error occurred while copying files to the  backup volume

    It won't give me any more details, how do i find out where the problem is?

    I've been doing more research on this, i downloaded the time machine buddy and this is what i got.
    Starting standard backup
    Backing up to: /Volumes/Time Machine Backups/Backups.backupdb
    Event store UUIDs don't match for volume: Macintosh HD
    Node requires deep traversal:/ reason:kFSEDBEventFlagMustScanSubDirs|kFSEDBEventFlagReasonEventDBUntrustable|
    I'm not seeing info on this error anywhere. 

  • HT3275 Red "i" message: "Unable to complete backup. An error occurred while copying files to the backup volume."  Restart, then try the backup once again. "

    I have tried reset, worked last week.
    But today got the same message and does not work yet, even with restart.
    Please help

    Is this Lion or Mountain Lion (ML)?
    We were hoping the new OS would fix the issues with ML.. but they got worse.
    Read C12, C17 and a brief scan over the rest.
    http://pondini.org/TM/Troubleshooting.html
    If you upgrade installed ML I would expect issues to abound.

  • My Time Capsule has stopped backing up.  I have an Apple Time Capsule which backs up by wireless. For the last 3 days it has not backed up. I get this message: "The backup was not performed because an error occurred while copying files to the backup disk.

    My Time Capsule has stopped backing up.
    I have an Apple Time Capsule which backs up by wireless. For the last 3 days it has not backed up. I get this message:
    "The backup was not performed because an error occurred while copying files to the backup disk."
    I have gone into Mac Help and followed this down to stage 4:
    under shared it lists my time capsule and my husband's iMac - both use the time machine but we have switched his off temporarily.  Clicking on my Time capsule I get "Connected" and "Sharepoint" - I didn't have to enter connect or password
    I don't understand stage 5: how and where do I select the disk or volume that contains Time Machine backups ?  How do I know which it is? My disk utility lists 160.04 TOSHIBA MK... with sub-heading Macintosh HD.  It also lists (with a "CD" icon) HL-DT-ST DVDRW GS22N
    Under stage 6, how and where do I Locate your backup ? I try dragging my Time capsule from Finder to the Disk Utility side panel but it won't go.  What is my computer's name?
    Please someone help!  I'm completely stumped.
    Thanks,
    Maggie
    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.

  • The backup was not performed because an error occured while copying files to the backup disk

    I continually see the error message "The backup was not performed because an error occured while copying files to the backup disk" when my time capsule attempts to backup. I have been receiving this message since 14/08/13. I have attempted to locate the file which is preventing the back up and I have not been able to locate it. Any help will be appreciated
    Thanks

    Do a verify on the local disk and on the TC..
    See the info here.

    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.

  • 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.
