From what I understand from the description of the
make_wchar_win32_path() method in win32/compat/compat.cc - we should
leave the function with the filename properly converted to VSS-based
one. But apparently we're stuck with local name.

The more I dig into it, the more it seems it is bareos after all.
Unfortunately, building Windows bareos-fd is no small feat so I cannot
directly debug it but.
I ran a procmon against bareos-fd.exe and it seems that while the FD
process does create a VSS snapshot... it doesn't read from it. It
reads the files straight from the main device. I did a small test
fileset consisting of just my user's registry file. And both procmon's
dump as well as bareos-fd own debug trace shows that it's trying to
read simply a c:\users\test\ntuser.dat instead of properly going for
\\?\GLOBALROOT\Device\HardDiskVolumeShadowCopyXX\Users\test\ntuser.dat.
That would explain why the job even though it's supposed to use VSS,
fails on copying open files.
When I created a very small example VS project just creating a VSS
snapshot and copying said file out of the VSS snapshot (using the
proper shadow copy volume path), it works OK.

OK. There is more to this than just bareos.
1. I used the script from this thread and it seems to be working
relatively well for backing up (I'm yet to test the restore part ;-))
the disk. I don't know, however how to backup whole mountpoint. If I
put the location of my symlink/junction/whatever that is, only the
junction point itself gets backed up, not the contents. I can't make
bareos descend into the mounted VSS shadow copy. I have to explicitly
list directories (like c:/vssmount/c/users) to back them up.
2. I spent whole evening yesterday trying to get vss to work,
regardless of bareos. I tried creating snapshots with " shadowcopy
call create Volume=C:\" and then symlinking them by hand and each
time I did them I was also getting access denied due to file open. So
there must be something else that the script provided in this thread
does and neither bareos nor manual wmic call do.
(My system here is Win10)

Hi Timo and Andreas,
I'd be interested to know how to handle this issue as well -
it's happening to a number of my FDs too. Did you figure out
how to get VSS to work on all files?
Thanks and regards,
Matt

Hey Andreas,
Windows Server Backup is working.
Those 3 files are just files to demonstrate that somehow
the bareos-vss is not working. Like i already mentioned,
as a workaround i can create a vss with a
powershell-script and ClientRunBeforeJob, then backup and
remove the vss with ClientRunAfterJob again. Also using
restic, for example, is working like a charm.
Best,
Timo

Check if the integrated Windows Server Backup works
or not.
Are you backing up only these three files, or are the
other files where
the backup works?
Best Regards,
Andreas
