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:

  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,

Della Li

    Is this the Registry location you are trying to find?

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tree\Microsoft\Windows\WindowsBackup

    How far into the location were you able to drill down to?

    See what this post says about Task Scheduler, do you have any entries in there?

    Hi,

    just one problem for me.....

    There is no "WindowsBackup folder" in the TaskCache\Tree\Microsoft\Windows to delete!

    Eek.

    Same "canot create a file error" for me as the others. Got excited until I navigated down the tree to find no WindowsBackup Folder.  Bah!

    Cheers any help much appreciated.

    If everything is working fine and you no longer need the backup of the Registry Key you exported to the Desktop, you can safely delete it.
