Vista - Vista Backup Failing : 0x80070002 Error Code

My PC tried to run its weekly backup tonight, but failed. This is the first
time this has happened - the last successful backup was on 4th February
2008.

Running Vista Home Premium, and I back up my C Drive files onto a second
internal hard drive.
This drive has two partitions (Z and F). Z is just used for backups, and
there is still 176GB free out of 238GB on the partition.

The error occurs only a minute or so into the backup attempt. The error
message that comes up is:

'The backup did not complete successfully.
An error occurred. The following information might help you resolve the
error:
The system cannot find the file specified. (0x80070002)'

Googling the problem shows others have had it, but no definitive resolution
is given.

I have tried deleting the backup task from task manager, moving the existing
backup volumes into a temporary sub directory, and creating a whole new
shadow backup from scratch in the root of Z. However, even this fails with
the same error. I'm beginning to suspect a registry problem.

Is this a known Vista bug? Will I have to wait for SP1 to resolve it?

Thanks.

I had some problems too, forgot what the error codes were but used a new
backup disk and it seemed to work, I don't know if the old disk is still
valid or not. I'm backing up to dvds, don't know about the internal drive.
Maybe backup can't handle some results properly.

That error code means that a file that initializes the component being
accessed is corrupt or missing.

Try running the System File Checker which will replace and missing or
corrupt system files.

Go to Start and type cmd.exe In the results, right click the cmd.exe
file and select the Run As Administrator option. In the command dialog, type
the following.

sfc /scannow

Press ENTER.

Run chkdsk on your C Drive. See if that solves the problem.
Right click your C Drive go to Properties>Tools and click the Check Now
button.

Ronnie,

Ran SFC but it didn't find any integrity problems.

Restarted and tried backup again - same problem.

Hi Colin
I have exactly the same problem with the exception that I have never been
able to get Back Up to work. Did you resolve the issue? Are we all waiting
for the next/first SP?

I tried the System file Checker suggested by one of the other replies.
Twice the verification got to 86% and then erroed with "Windows Resource
Protection could not perform the requested operation."
Any further ideas. I'm especially miffed as I've just paid out for an
external HD to back up to..

BTW Does anyone know of good software to back up VISTA Home Premium that
will restore when required?

HiFi,

Yes - I have managed to resolve it but it certainly wasn't easy.

It seems to be caused by an error in the registry which is somehow caused
when a user profile is removed. Keys are left in the registry which lack
Profile Image Paths. These then cause Restore & backup to fail with the
0x80070002 error.

This is what I did (don't attempt if you are not confident hacking the
registry):

Look at the keys under:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

The longer value keys will have ProfileImagePath values with values such as
'C:\Users\Username' where Username is the name you have given a User
Profile.
However, you may have some keys in there which lack a ProfileImagePath value
altogether. These would seem to be erroneous.

I deleted two keys which did not have this value (save copies before you
attempt to delete them). Then when I retried Backup & Restore centre it
worked perfectly.

I have alerted this problem to the appropriate team in MS. It shouldn't
happen!

As for your SFC issue, that may be something different altogether. Doesn't
sound good though.....

I've had the same problem, but from first trying to backup (to a new
external HD). I've checked the registry as you suggested, but can only find
my own username listed as a ProfileImagePath in the ProfileList
(unsurprisingly, as I had never set up any others - I use the PC as
Administrator) - with the exception of three, which end in: systemprofile,
LocalService and NetworkService: I presume these are OK.

I ran sfc and, although it completed, it said that it "found corrupt files
but was unable to fix some of them". It referred me to the CBS.Log (which I
had trouble getting access to!), but nothing in the huge volume there jumped
out at me (although I've never seen them before).

Any other thoughts?
