Windows Backup failed. Error: Access denied (0x80070005)

My sister wants to use (final) Vista's integrated backup feature on her
notebook to backup her data to DVD-RW. Problem is she always gets the
message: "Windows Backup failed. Error: Access denied (0x80070005)"

Looks like backup is denied access to some files even though I stopped all
running applications (which shouldn't be necessary due to Vista's Shadow
Copy).

So I go into Event Viewer which only gives me the same error message like
above and an event ID: 4104. Detail view shows me the same information in XML
format and Event Log Online Help is no help.

Then I find the folder C:\Windows\Logs\WindowsBackup with .ETL files in it
which I can open in Event Viewer. But the only thing they contain are log
events that all look like this: "GUID=dbd33fcd-cfba-5174-7b1a-a59ff2eef057
(No Format Information found)." Again each one with an event ID. The event
IDs are 11, 13, 14, 15, 21, 22, 23, 31, 33, 35, 36. Again, detail view, Event
Log Online Help, and web search turn up nothing.

I don't understand why Microsoft doesn't at least log out the files which
Windows Backup was denied access to. Backup is important for me, but I'm
clueless about what I can do at this point.

Any idea is appreciated. Thanks in advance.

Did you ever get a reply? I'm having the same problem.

No, unfortunately not. And the problem still persists.

I am having the same problem. Any help?? I am able to receive windows
updates ok but can't do complete backup nor selected files backup. I have
Vista Business edition. When I try and do complete backup it says not all
volumes were selected so I can't do this even though all volumes are
selected. Need help with this problem too. Maybe the two are related.

I had the same problem. In my case Norton Anti-Virus was detecting that the backup file was a virus and deleting it while it was being created. I disabled Auto-Protect and was able to complete the backup.

*Error 0x80070005 means that a file required is in use.
I have the same problem, I'm assuming what it means is one of the files
that it's trying to back up.
If this is because the system needs write access then the question of
why is a puzzler.
I can't imagine it needs solo read access to files as this would make
the whole backup process a non starter(?)

So for full system backups you need to power off the PC?

I would say that this is your problem.

Why would a back-up abort just because a file is open? It would just go
around the opened file and not back it up, going on about its business.

Because to this day MS hasn't figured out how to allow a privileged
process to (at least) acquire a read only handle to a locked file. They
work around this by using shadow copy, but if you're not working from one
then...

So, you're saying that what is in the link is not coming into play in
some situations where access is denied. I find it hard to believe that a
back-up would blown down because a file is open during a backup, and the
back-up just wouldn't go around it and continue processing.

Hi, I have had the same problem in trying to back up Vista ever since I had my PC. I have just noticed that there is a conflict between "Roxio" drag to disc and Windows explorer.
I have un-installed all the "Roxio" programs from my system and Vista backup now works perfectly.
Hope this helps - Chris

I have had a similar problem - same error code. I've got Kaspersky on my Vista system though. When I disable Kaspersky, I can perform the backup, but not with it turned on. Has anyone come up with a better workaround than turning off the Antivirus for every backup?
