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.)

  • 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.

  • Recent backups fail: "An error occurred while copying files to the volume."

    I recently moved to a new place and set up Time Capsule as a bridge. Backups were working fine for the first couple days but then, out of the blue, I got a message that said the password I entered for Time Capsule was incorrect. I entered the correct password and hit OK. Time Machine was able to connect but now backups fail with this error: "Unable to complete backup. An error occurred while copying files to the backup volume."
    Time Machine indicates it is "preparing backup" for a few minutes, then sits at "zero of __MB completed" for a long while, finally starts backing up and gets to the end but then fails. Console indicates "unexpected reply from backup server; ignored."
    None of these attempts have fixes my problem:
    --I have deleted my TC passwords in Keychain Access.
    --I have tried downloading the latest Airport Utility and re-entering the TC disk's password in both Airport Utility and in Time Machine preferences.
    --I have restarted my computer and unplugged & plugged back in TC.
    My Internet connection works fine; TC's light is solid green. I can enter Time Machine to restore backups without a problem. The backups just fail every time now. Any ideas?

    The problem really isn't the speed of the backup; it's done in 5-10 minutes, but each time it finishes, TM reports it has failed. I don't believe plugging it in overnight or letting TM try over and over will fix the problem. I've tried to manually start backups a number of times, and have let TM try to start and complete them on its own but they consistently fail.
    It would be an awful shame if I had to delete my old backup--I bought the Time Capsule for the specific purpose of having backups that go back months and I don't want to lose what I've already backed up.

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

    Add me to the list of those with TIme Machine backup failures.
    I am repeatedly getting the following error message:
    "Unable to complete backup. An error occurred while copying files to the backup volume."
    I do have work-around.
    1. Open Time Machine Preferences... (from the Time Machine menu in the menu bar)
    2. Change Disk...
    3. Re-select the disk you are already using and select "Use for Backup"
    4. Back Up Now (from the Time Machine menu in the menu bar)
    The error eventually comes back, but following the above procedure keeps it at bay for a few days.
    I have only had these errors since 10.5.3.

    Mle,
    Take a look at the following...
    *_“Unable to Complete Backup. An Error Occurred While Copying Files to the Backup Volume.” (Console: “Error: (-43) copying”, “Copy stage failed with error:11”)_*
    There are several reasons why this error message can appear. Consider each topic individually. If one does not resolve the issue, move on to the next one. The following topics have resolved this issue for others.
    *If A Backup Is Interrupted* #
    “If an interruption occurs, Time Machine will wait for a period of time to see if the Time Capsule becomes available again. After this time expires you will see a alert message stating "Time Machine Error. Unable to complete backup. An error occurred while copying files to the backup volume." In Time Machine preferences, the "Latest Backup:" field will state "Failed".” [http://support.apple.com/kb/HT1176]
    You will need to reestablish communication with the Time Machine backup disk.
    *Anti-Virus Software* #
    Have you been running anti-virus software? xClav, Norton, Sophos, Macaffe etc... According to many posters in the forums this software can play havoc with Time Machines attempt to function properly.
    *Firewire Devise Interferes with Time Machine Backups* #
    If you are backing up to an external hard disk by means of firewire, do you happen to have another firewire device attached as well? An iSight camera or video recorder maybe? Sometimes additional firewire devises can interfere with the signal/power to the backup drive. Unplug it and attempt a backing up again.
    *Corrupt File / Incorrect Permissions* #
    One poster observed: “I searched my system logs and found a file that caused my connection to the TC to fail. I erased that file (after checking what it was - a temporary file connected to my Epson scanner) and tried again to back up for the first time. This time it worked, and in under 10 hours (I had been expecting about 20-24 hours, based on the data transfer speed).”
    Initially this might be resolved without deleting the offending file. Simply use Disk Utility to “Repair Disk Permissions”. Or failing that, booting from the Mac OS X Installation DVD and running “Repair Disk” on the Mac’s internal hard disk. Now try backing up
    Otherwise, you may need to track down the specific file causing Time Machine to choke.
    Before attempting another backup, go into Applications --> Utilities --> and launch Console.
    Under “LOG FILES” on the left select "system.log".
    In the search field in the upper right, type in backupd. This is the process Time Machine uses to perform backups. By searching just for this process we'll isolate only Time Machine activities.
    With the Console open, attempt another backup and note the time it starts and the time it stops. Often, the activities reported will identify the very file or event that caused the attempt to choke. (You can copy and paste the events for this backup attempt from the log into a post here and we may be able to tell you exactly what is happening.)
    Once you determine which file or event it is, you can decide whether to move, delete, or modify certain things and then attempt another backup. For Instance, if the logs report something like this:
    +Error: (-43) copying /Users/Home/Library/Application Support/Quicksilver/Actions.plist to+
    +/Volumes/Backup HD/Backups.backupdb/My Mac Pro//Users/Home/Library/Application+
    Support/Quicksilver
    Then it’s telling you Time Machine is choking on the file labeled Actions.plist and it’s having trouble copying to the backup disk.
    On your computer, Navigate to that file ( Actions.plist ) and move it to the Trash, but DON’T empty it yet. Now try backing up again. If it succeeds, you can launch Time Machine and go back 24-48 hours and restore a copy of Actions.plist and replace it. Then empty trash.
    *Partition Scheme/Formatting Issue*
    This KB article explains one reason you may be seeing that error message [http://support.apple.com/kb/TS1550]. It's a partition scheme issue. Time Machine is incompatible with disks partitioned as Master Boot Record (MBR). Unfortunately, this describes nearly every hard drive you can buy because MBR is a Windows partition scheme. You will likely need to repartition the drive and start again. (Naturally, this DOES NOT apply to Apples’ Time Capsule.)
    One article on Time Machine made this observation: “Virtually everybody will have to open Disk Utility and repartition the disk as APM or GUID. It doesn't really matter which one because the Time Machine disk will not be bootable anyway. APM allows a disk to boot a PowerPC, GUID allows the disk to boot an Intel processor but both are easily digestible by Time Machine on either kind of processor.” (http://www.girr.org/mac_stuff/backups.html)
    Once the external hard disk is repartitioned, select it again in Time Machine preferences and use it for your backups.
    Let us know if any of the suggestions above resolved your issue.
    Cheers!

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

    I erased and restarted my time capsule numerous times and tried re backing up. Little more then have way through i get this message "Unable to complete backup.

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

    I get this message when I try to backup:
    "Unable to complete backup. An error occurred while copying files to the backup volume."
    I think one of Apples OSX 10.5 updates this summer is responsible. But how can I find out? The error message gives me nothing to look into.

    Hi,
    Im getting a similar problem, but for my SafeBrowsing.db file? I tried following the troubleshooting but still can't fix it. Tried excluding it and deleting the file, but it came back.
    When I excluded/deleted it, the code changed from:
    (36) SrcErr:YES Copying /Previous Systems.localized/2010-09-07_1127/private/var/folders/Aw/AwKhbHXwG6ejptMGZnOq9E+TI/-Caches-/com.apple.Safari/SafeBrowsing.db

    My new disk is a Seagate, seems to copy files manually pretty well, just gets snagged on this Safari file that doesnt seem to have much use.
    Any help would be great.

    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...".

    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?

  • HT3275 How do I correct this problem - Time Machine could not complete back up. An error occurred while creating the backup folder? The problem started on 5th March but I had backed up to an iomega HD since I got my iMac in October.

    I have had a problem since 5th March with Time Machine on my iMac. I have had no problem since I got the computer in October backing up to an iomega HD but now I keep getting a message that "Time Machine could not complete the backup. An error occurred while creating the backup folder". Anyone know how to correct this?

    I had the same "Error creating the backup folder" error - many times over.
    I went into the Disk Utility, selected the Backup Disk and ran Verify. It checked out OK. But if not, could have run Repair.
    Then did a complete shutdown and restart of the iMac and then tried "Backup Now" from the Time Machine icon's menu - it worked fine.

  • 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.

  • 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.

  • "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.

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

    And the saga continues...
    I haven't been able to use Time Machine for a week now because I keep getting the "Unable to complete...".
    What I've noticed is that, in my case, Time Machine stalls at 15.73G - out of 33.77G. It stops for a while, then "finishing backup" appears in the Time Machine pane in System Preferences and then the "unable to complete..." comes up.
    I've erased the external USB HD Time Machines backs up to - Iomega 250G - but to no avail.
    What is most frustrating is that Time Machine was one of the reasons why I updated to Leopard.
    Could it be that names of files might be at the root of the problem? I mean, some of my files have names in Portuguese. However, this was not an issue before last week.
    Any ideas would be most welcome!

    Grr.. now i'm getting constant TM failures too. I found the backupd errors in "All Message" in Console, and they are certainly files that I don't want to delete! (Obviously the first 2 are my iTunes library and my Entourage email!) What now?
