Windows Backup .... Cannot create a file when that file already exists. (0x800700B7)

Anonymous

I installed VISTA 64 last summer.

For the first few months I was able to do BACKUP FILES without a problem

Now when I try I get this error message

Windows Backup

File Backup could not save your automatic backup settings for thefollowing reason:

Cannot create a file when that file already exists. (0x800700B7)

Please try again

I can still do a COMPLETE PC backup

I've had other issues with VISTA 64 you can see the resolutions ANSWERS beta at

http://social.answers.microsoft.com/Forums/en-US/vistawu/thread/c6677691-6bd2-452d-9995-c110c51d2702/

when I do a search on google with

Cannot create a file when that file already exists. (0x800700B7)

I see that there are many with the same problem

ANY ideas and collaborations are welcome

Well this issue has been finally resolved thanks to

MS SUPPORT engineer Della and her friends. Please see her reference below.

I must admit that this problem had dozens of people baffled for months.

So after asking for Della's permission to post it here I can say that this resolved it 100%

So, thanks to every one that was inviolved in this

Take care

I would apologies that we may not run the command prompt, as this is not commended and cannot resolve our issue.

After discussing it with my fellow with engineers and further researching on the internet, let us try the following steps for troubleshooting.

Backup registry keys:

Click “Start” -> Under “Start Search” -> Type “Regedit” and press Enter
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache
Right click on TaskCache and select export
Save to a file on the desktop.

After that, please delete the WindowsBackup folder in the TaskCache\Tree\Microsoft\Windows.

Please try to the WINDOWS BACKUP files again.

This time, let us try to set the automatic file backup again. Please try to set the follow settings.

How often: weekly

What day: Monday

What time: 19:00

Please try the above steps and let me know the results at your convenience. I look forward to your reply.

Best regards,

Della Li

Fix for System Restore error (0x800700B7) for Setting Manual Restore Point

http://social.technet.microsoft.com/Forums/en/itprovistahardware/thread/725c6f1a-2f62-4a1c-8072-ac82fbbd87ab

Start-up failure / unable to use system restore

http://www.windowsbbs.com/windows-vista/80192-start-up-failure-unable-use-system-restore.html

Try running ChkDsk to check your drive for errors. Right-click your Drive icon/ Properties/ Tools/ Error Checking. Try it first by not checking either box (this will run it in a Read-only mode) to see if it flags any hard drive or file problems. If it does, restart it by ticking both boxes, and rerun it to allow it to attempt to fix any found problems.

Will System Restore work from Safe Mode?

I changed "Maximum Shadow Copy Storage Space Value" from 1.041 GB to /maxsize=300Mb. This did not fix the problem. I have not changed the setting back to 1.041Gb. Please advise.

System Restore doesn't seem to be an available option in Safe Mode.

I ran ChkDsk and several corrections were made. System Restore Point problem continues to exist, however. (File Backup still works as expected.)

What's next?

(Did I mention that this is a Vista Ultimate machine?)

Okay, I did that. I can now utilize the Backup Files function in the expected manner. However, I still get a 0X800700B7 error message when trying to set a manual Restore point. How do I fix that?
