Re: CreateVssBackupComponents access denied ?

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

<Mark> Have you been able to create a shadow copy while running as a standard
user on Vista when UAC is
turned on?
<IEURO> No, it's impossible to run as a standard user on Vista.

I has the same program like your before. At this moment, my program can
support backup and restore snapshot operation on Windows Vista.

You can read this artical in codeproject "Making Your Application UAC Aware"
(http://www.codeproject.com/vista-security/MakingAppsUACAware.asp) . It's
very helpful for requesting administrative permission.

Thank you. I tried this before, but it didn't change the result. If I call
CreateVssBackupComponents() as a user with a standard token, it returns
access denied. It works fine when I run the program as an administrator. I
notice in your other thread you are using VSS also. Have you been able to
create a shadow copy while running as a standard user on Vista when UAC is
turned on?


Thanks,
Mark

You need to enable the backup privilege when doing backup operation.
Therefore, it also need to enable restore privilege when doing restore
operation. You can read the "Setting the Backup and Restore Privileges"
artical in http://msdn2.microsoft.com/en-us/library/Aa387705.aspx .

I'm using VSS, and when I call CreateVssBackupComponents() under Vista
with
UAC turned on, I get an access denied error. MSDN just says this about
this
error:

"The caller does not have sufficient backup privileges or is not an
administrator."

Is my only option to run my application as an administrator? My
application
is currently manifested just as a standard user (asInvoker). What are
the
"sufficient backup privileges"? Is there any way to use
CreateVssBackupComponents() as a standard user?


Thanks,
