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

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

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

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:

 

1. Click “Start” -> Under “Start Search” -> Type “Regedit” and press Enter

 

2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache

 

3. Right click on TaskCache and select export

 

4. 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,
