Are you certain that you are running as Administrator, not just as a user that 
can elevate permissions (with UAC)?

UnauthorizedAccessException means that your user does not have the correct 
permissions.
Maybe the user is blocked from creating VSS snapshots?

I will need to revisit how my wife's account is setup. I know she is a member 
of the Administrator's group, though because i checked after I got the error. 
Maybe I should turn off UAC (if it isn't already). I also  don;t know about her 
being blocked from runnning VSS as I did not set anything special up and was 
able to use another application to do a VSS full image backup of her system 
disk. I will check and report back. 

I recently found Duplication because Steve Gibson mentioned it on Security Now 
and I do love what i see so far and am anxious to get it working. Can't wait 
for the version that allows it to run as a service.

I just checked and her account is definitely an administrator account. I've 
disabled UAC through group policy but am still getting the error. However, the 
error is appearing even though Outlook is NOT running and the files should not 
be locked.

Am I the only person having thi sissue?

Do I need to install Microsoft Visual C++ 2008 SP1 Redistributable Package (x64)
in order for Duplicati to use VSS on Windows 7 x64? 

Could there be a conflict between running 32-bit Duplicati on a 64-bit OS and 
using VSS which is causing VSS not to work?

This just does not work with locked Outlook PST files on Windows 7 x64. I tried 
running Duplicati on another Win7 X64 system and have the same problem. I am 
definitely an administrator on both systems and have sanapshot-policy=auto 
enabled. Too bad. I know it works on Windows XP OK. If you look at my first 
note in this hread, i see a reference to 
Alphaleonis.Win32.Vss.VssImplementation.CreateVssBackupComponents()
I am running a x64 version of duplicati. Just wondering why it's calling a 
Win32 method. 

Failed to process file: X:\Outlook\James Mail.pst. Error message: The process 
cannot access the file because another process has locked a portion of the file.

Strange, I have developed the VSS support on a x64 Win7 machine, so I am quite 
sure it works.
The name "Win32" is a legacy term back from when Windows became 32bit (it was 
16bit before), and now they are stuck with that name, even though some stuff is 
now starting be called Win64.

To run Duplicati.exe as admin, you must first close all running instances 
(check with taskmgr.exe).
Then right click the Duplicati icon in the start menu, and choose "Run as 
Administrator". AFAIK, that is the way to do it. Even if your account is an 
Admin account, you will not get elevated privileges unless the process 
specifically asks for them, and Duplicati does not do that. I have heard people 
working around this by setting a schedule that starts Duplicati as admin. Then 
they set the schedule to run 5sec after login.

And yes, you probably need the C++ redist, but you will not get an 
"UnauthorizedAccessException" if the redist package is missing.

I set the exe to run as administrator but same error. I think this is broken 
for Outlook PST files. I will ty some other locked files to see if they gat 
backed up.

OK. I think the issue is only with Outlook PST files that are open. Duplicati 
will backup EXE files that are in use and that I cannot delete interactively 
because they are open.

Would you be able to test this on Outlook PST files to confirm that this is an 
issue?

BTW, it DOES WORK on Windows XP but not on Windows 7 x64.
Thanks.

There are different ways to lock a file in Windows and Outlook uses the hardest 
kind of lock. The .exe files are usually just locked with read access. Outlook 
prevents any read and write access to the pst files while running.

I seem to recall some weirdness with setting that "Run the program as 
administrator" flag, where it would not always kick in after a reboot, but I 
have not yet investigated it.

Have you tried exiting the Duplicati from the tray, and then right clicking 
"Run as Administrator" ?
In my experience that always worked.

Yes, I've tried everything but nothing will allow Duplicati to backup open PST 
files.

I just tried this again, Win7 x64, UAC on.

Exit all Duplicati processes.
Right click and say "Run as Administrator".
Click Yes to UAC prompt.
Run backup with snapshot-policy=required.
All good, no error messages.

Repeat without "Run as Administrator".
Fails with "Attempted to perform unauthorized operation."

If you are 100% sure you are running as administrator,
I am guessing that something else is blocking you.
You can try running the tool Duplicati.Library.Snapshots.exe from an 
Administrator command prompt and see if you can get a more exact error.

Do I need to start duplicati with a command line option to enable snaphots or 
just do it through the GUI?

This is weird. for some reason it appears to be working now. I have to confirm 
with more tests. I did uninstall ShadowProtect backup which also uses it's own 
snapshot manager but not sure if that was the reason...Stay tuned and thanks 
for your help.

May I ask how you did it? I cannot get it to run with admin priv so it can use 
the volume shadow copy.

If i recall it just started working mysteriously. The only option i have 
selected is snapshot-policy=required

It would be best if Duplicati had a user option in Windows to force it to run 
with administrator permissions at startup.  It is reasonable to expect a backup 
utility to demand administrator permissions while running.  However, a 
one-size-fits-all solution would be a checkbox that requires Duplicati to 
verify that it has been run with administrator permissions.  This might have 
saved a bit of debugging time for me.
