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

Hmmmm. "Run as Administrator" did not help. I am logged in as an "Administrator" in any event. I had forgotten about "Process Monitor" -- I had v2.0 -- and "Event Viewer."

I am not "dual booting." It is strictly a Vista Ultimate machine.

Anyway, I won't have much time for this today but will get back to it tomorrow... or over the weekend.

I wonder whether those Registry Cleaners are running System restore under another user account, perhaps System etc. rather than your account? Did you ever test for problems if you created a different user?

If you launch System Restore via the Start Menu\Programs\Accessories\System Tools, and right-click on the System restore shortcut and then select the "Run As Administrator" option, does that allow you to create a restore point?

A program like this might allow you to see what is going on under the hood with System Restore, hiccups because of access permissions might be a problem?

Process Monitor v2.8

When you dual boot XP with Vista or Windows 7, the latter two lose all restore points every time you boot into XP. That is because XP makes changes to the System Restore files on all drives. Maybe you are seeing something like that?

Have you tried tackling the Event Viewer yet, it is enough to make ones hair fall out (you'll see what I mean), but it may have some errors related to System Restore or Volume Shadow Copy?

Okay, I did all that... no joy. I am, however, back to the 1.041Gb Copy Storage Space.

Interestingly, I can create a "Restore Point" with 3rd Party programs -- Registry Cleaners that suggest a Restore Point creation before application. I just cannot do it manually. I, also, notice that only one retore point is saved -- with 3rd party programs creation deletes previous Restore Point.

The hard drive manufacturer will have free (bootable) software on their site which will thoroughly check the condition of your hard drive. It may be worth running that diagnostic software if every time you run ChkDsk it reports (and fixes) errors.

System Restore wouldn't allow the creation of restore points is Safe Mode for me either, probably because of being in Safe Mode, it would allow a restore to be run however.

What about turning off System Restore on all drives, rebooting, and then turning it back on. That might get its' act together?

Turn Off System Restore

See what this article says about "Maximum Shadow Copy Storage Space Value", concerning that 300MB setting.
