Windows Backup Error code 0x8100002f

    Question

  • Setup: Have Win7 RC1 on my c: drive and have changed the settings so that all my data ( documents/pics/videos/music etc ) are on a different physical drive ( E: drive ). I have formatted another drive  and calle dits X drive and allocated it that number as well. X drive is an external hard drive connected via esata .

    Now I have selected X drive as my backup drive but when it runs it comes up with a message about Backup Fails etc but when you close this message box the backup is running. When its finishs I get an error about some problem and files been skipped. Also the notification flag has a message "check your backup results " and fshows some files that were skipped :

    Backup encountered a problem while backing up file C:\Users\Bill\Documents. Error:(The system cannot find the file specified. (0x80070002))
    Backup encountered a problem while backing up file C:\Users\Bill\Pictures. Error:(The system cannot find the file specified. (0x80070002))
    Backup encountered a problem while backing up file C:\Users\Bill\Videos. Error:(The system cannot find the file specified. (0x80070002))

    So basically I think moving the Docs/Pics/Videos to another drive is causing these above errors but why does it say the backup will not be run and then runs.

  • Hi,

    Thanks for trying Windows backup. Actually, what happened in your case is that the backup succeeded but ended up skipping some locations because it could not find them. We backup Documents, Pictures, Music and Videos through user libraries. Since you have changed the location of these folders, the libraries won't recognize them unless you navigate to the corresponding library through the Explorer UI. For example, to navigate to the Documents library, click on the Windows icon and click on "Documents" to the top right. Can you make sure you navigate to each library atleast once? Once you do that, the right locations will be updated and backup will start backing up the new locations. Please try this out and let me know if it works for you.

  • Sneha,

    I have the same problem as wls54 above - I have moved all my libraries to the D drive; Windows is on C.  I am backing up to F.  And I have navigated to each library on D but I still get the error.

    Is Backup doing the backup anyway but then spitting out the error?  Or is it failing to back my libraries on D up at all?  I think when I adjust the location of a library folder like "Documents", Windows Backup shouldn't need me to navigate to each folder first - it should reflect the change automatically, shouldn't it?

  • Well have did what you suggested and just maybe the problem was caused by two locations ie. the public  files still on c: drive

    Anyway I have deleted that location anf hopefully later on I will check it out  and see how it goes

  • Well tried again and same problem. 


    I think I will just save / backup the files that I want in future and not bother with Windows Backup

  • Regret the inconvenience caused. I agree that this is not the best behaviour. This is a bug wherein the location stored in the library gets updated only when the library is actually opened in Explorer. Just to confirm, you need to navigate to the library and not the constituent folders. Can you confirm whether you did this? For example, to navigate to the Documents library, click on the Windows icon and click on "Documents" to the top right; you do not need to navigate to the "My Documents" folder. Please let me know the result.

    I am having this problem with my backup, except it only gives me the error for my Documents folder. I moved all of my user folders from C:\Users\username\ to a folder on a separate partition D:\username\. After running the backup, it says "The backup completed but some files were skipped." When I click options and error details, the error code is 0x8100002F. When I click "view skipped files" it opens a notepad window with the following: "Backup encountered a problem while backing up file C:\Users\username\Documents. Error:(The system cannot find the file specified. (0x80070002))." I can confirm that I indeed browsed to my Documents library, not just the folder on the D: drive, and this did nothing to remedy the problem.

  • On my desktop the backup gave me a similar error, but this time with the Documents, Music and Videos folders. Again, browsing to the libraries did nothing to fix the problem. This is the error log I received:

    Backup encountered a problem while backing up file C:\Users\username\Documents. Error:(The system cannot find the file specified. (0x80070002))
    Backup encountered a problem while backing up file C:\Users\username\Music. Error:(The system cannot find the file specified. (0x80070002))
    Backup encountered a problem while backing up file C:\Users\username\Videos. Error:(The system cannot find the file specified. (0x80070002))

  • Hi,

    Looks like the updated locations of your folders are not getting reflected in your libraries. We will investigate on the issue. Meanwhile, as a workaround, please try the following:
    1. Click on "Change backup settings" from troubleshoot dialog
    2. Expand the user node whose libraries are getting reported as skipped.
    3. Deselect the library that is causing the issue.
    4. Expand the "Computer" node in the treeview and select the redirected location of the folders. 
    5. Save settings.
    You should not hit the skipped files issue after this.  Hope this helps.

  • Thank you for your response. This is actually exactly what I did myself as a workaround. But this bug should definitely be fixed before RTM. I don't know where it's getting confused because the libraries are being updated to reflect the new locations. They point to the proper location on the new partition and there is no longer any reference to the default location on the C: drive. Yet the backup fails to backup the new location because the old location doesn't exist. It's only for some of the moved user folders and it doesn't always occur when the folders are moved. But it does seem to only be a problem with user folders that are part of a library. I tried moving my Documents folder back to its default location and moving it again, but this didn't change anything either.

  • Having the same problem with Win 7 Pro..

    My log started with:

    Windows Backup skipped C:\ because is it on corrupted drive C:\. (does this have something to do with the fact that I installed Win 7 over the RC from Windows GUI (so no format?))

    and then it had libraries etc listed.. I lost the log because I did a manual back after it which seems to go through ok. So this issue only exist when doing a scheduled backup.. weird? Definately not fixed.
    Monday, October 12, 2009 4:35 PM
  • Hi natiainen,

    Looks like your C:\ had some bad clusters. Could you run chkdsk /R on C: and see if it flags any errors?

    And when you say your manual backup went through OK, can you tell me what steps you took to perform a manual backup?

    Thanks,

  • Hi Sneha,

    I ran chkdsk and it found no problems. I also checked the log from the earlier chkdsk (12.10.09) I did when I had the backup problem and no problems there either.

    By manual backup I just went to the Backup and Restore center and did "Back up now" with the same backup settings as the scheduled ones. This is not the first time the scheduled had this failure but this time I decided to google the problem instead of just doing a manual backup.

    Wednesday, October 14, 2009 6:33 PM
  • Hi natiainen,

    It is not expected that manual and scheduled backups give different results. Can you let another scheduled backup happen and see if this behaviour repeats? If so, please pass on the contents of <<SystemDrive>>\Windows\Logs\WindowsBackup to sneham_at_microsoft_dot_com (Remove underscores and replace words with characters wherever applicable).

  • That did the trick, no issues detected.

    Is there a way to view what the backup includes. I mean, say the backup only uses 30% of a 300GB harddrive. That's 90GB, but what if I had more than 90GB in the folders I chose it to backup, what gets chosen?

  • Hi Emperium,

    It is not possible to specify such limits as of now. If you choose to backup folders that are greater in size than available space on the backup disk, the backup will fail. Please read the following link on how to manage your backup space: http://windows.microsoft.com/en-us/windows7/What-backup-settings-should-I-use-to-maximize-my-disk-space

  • Exactly the same problem here, Windows 7 Ultimate and backup just fails every time with the same "corrupted drive C:\" errors. Running chkdsk /r does not help any.
    Thursday, April 22, 2010 7:50 AM
  • Hi euforium and acachia_,

    Looks like your C: has some bad sectors. Please do the following:

    1. Open an elevated command prompt (cmd -> Run as administrator)
    2. chkdsk /R C:
    This will schedule a disk check during next reboot.
    3. Reboot your machine.
    4. Re-run backup.

    Hope this solves your problem.

  • Hi Sneha,

    I'm getting the same error code (Error code: 0x8100002F) but the log looks like this for me:

    -----------------------------------------------------------------------------------------------------------

    Backup skipped backing up F:\ as it is on the backup target.

     

    Backup skipped backing up F:\ as it is on the backup target.

    Backup encountered a problem while backing up file C:\Users\Mcx1-MARK-PC\Contacts. Error:(The system cannot find the file specified. (0x80070002))

    Backup encountered a problem while backing up file C:\Users\Mcx1-MARK-PC\Searches. Error:(The system cannot find the file specified. (0x80070002))

    -----------------------------------------------------------------------------------------------------------

    I'm kind of just ignoring the skipping of F:\ as that is the new 1 TB external hard drive I just bought on Monday and I don't even have drive F:\ chosen as one of the drives to back up, only the C:\ and D:\ drives are set to be backed up, but I don't quite understand the system not being able to find the Contacts and Searches folders. I'm a little confused because under "Data Files" on the "Set up backup" window I have three possible boxes I can check: "Back up data for newly created users," "Mark's Libraries," and "uuid:10000000-0000-0000-0200-0022483035E8's Libraries." Mark's Libraries is obviously my library but what is that huge uuid library?

    Also, I don't understand why under C:\Users I have both a "Mark" directory and a "Mcx1-MARK-PC" directory. The "Mark" directory contains all the folders/files that I find when I look under my libraries via the Start button whereas the "Mcx1-MARK-PC" directory does not contain the Contacts or Searches folders, hence the error message. I don't get why Windows Backup is looking through the libraries for whatever this user directory is however, rather than just the "Mark" directory which contains all the correct files/folders. I don't really know where the "Mcx1-MARK-PC" directory came from to be honest but when I look through it in Windows Explorer, every folder within it appears to be empty, yet when I view the Properties of "Mcx1-MARK-PC" it says that its Size is 116 MB. Should I simply delete the "Mcx1-MARK-PC" directory or do you by chance have any idea what it could be or what created it?

    In case it helps, here's what my system is running:

    Windows 7 Professional
    Processor:  AMD Turion 64 X2 TL-62   2.10 GHz
    RAM: 4.00 GB
    System type: 64-bit Operating System

  • Hi Mark,

    This user Mcx1-MARK-PC is created by Windows media center. A user created like this does not have the Contacts and Searches directories. You can safely ignore this error or exclude these locations from Change backup settings wizard to eliminiate these warnings.

    Also the huge uuid that you see in the Change backup settings wizard is because the friendly name for the user created by Media center is unavailable.

    Try mklink /J "C:\Users\%username%" "D:\%username%"

    This will create an NTFS Junction Point to the correct folder.  A junction point is basically a link on steroids.  Programs trying to access the junction point will believe that they are in that folder when they are in fact in the folder linked to.  This is useful whenever a program uses hard-coded directories rather than the environment variables it's supposed to use.  I set up a bunch of these as a precautionary measure since I had to move a lot of files to my second hard disk as my first one is a small SSD (30GB).  This won't work if you already have a folder with the link name

    Syntax:  mklink /J <Link-Name> <Target>

  • I am having the same problem and I don't care about one skipped file but I want to know if the backup is all right. If not I will delete it and copy everything over by hand. Can you please answer whether this error makes  the backup unusable or can it still be  restored.
    Saturday, November 12, 2011 4:42 PM
  • Perhaps the backup could report as "partially failed" instead of "failed".  My problem with this error is that I have no "Last Backup" showing.  The reliability of the backup itself is dubious.  I am typing in a forum where I should be happily using a product that came with Win7 OS.

    Here is the expected behavior and what I will be looking for in a third-party product:

    1) Did the backup miss files?
    2a) Yes? 
    3a) Inform user of missed files with a list or other *reasonable* representation in the UI (partially fulfilled by error 0x80070002), a "caution" icon and a Yellow color should be used *unless the backup completely failed* (i.e. no files were backed up).
    Final Result: "Last Backup" field should show "[date] [issues]", if user wishes to interact with "[issues]" (arbitrary UI interaction), they can immediately see a list of files skipped.  


    1b) No? 
    2b) Why are you in this forum then?

    Result: Backup working normally, "Last Backup" field reports date of last backup with no error state.

    • I am only a novice and at a loss what to do - Windows 7 32 bit backing to a Seagate 1TB External Hard Drive.

      I have read the knowledge page and can not make any sense of it. I do not know computers.

      I have an issue with my backing up and it skipping one file.

      I recently had my external hard drive crash.

      It looks like one file location that causes the issue.

      What can I do to rectify the situation so that I can back in a manner that creates a clean back up to my external hard drive?

      Any assistance will be appreciated.
