I have been using Bacula to back up a Windows 10 virtual machine client in
addition to a number of physical Linux clients without any problems for several
years.
Recently I upgraded the win10 vm to Windows 11, and I am now getting an error
message from the VSS snapshot system. I don't know if this is a permission
problem. I also don't know how serious it is - is just one file affected, or
is all of C:\ affected?
The error message is a bit confusing, because it says there is a read error on
the file and the media is write protected.
I've tried deleting shadows using vssadmin but that didn't help. The file that
is triggering the error is on a Nextcloud shared directory, but that was
working fine with win10.
I'm not sure how to troubleshoot this. Any guidance would be appreciated.
