I decided to exclude the Nextcloud content from my Windows client backups and
snapshots, because that content is already backed up on my Nextcloud server.
In case this would benefit others, here is how I did it. There are two
relevant pages that I found that document the process:
https://learn.microsoft.com/en-us/windows/win32/backup/registry-keys-for-backup-and-restore
https://learn.microsoft.com/en-us/windows/win32/vss/excluding-files-from-shadow-copies
I used regedit (as admin), and I added keys to the following:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\BackupRestore\FilesNotToBackup
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\BackupRestore\FilesNotToSnapsho
The new keys are named "Nextcloud" and are of type "Multi-String Value". Here
is an example:
C:\Users\sfalco\Nextcloud\*.* /s
After a reboot, Bacula no longer complains about Nextcloud.

Thanks! That does sound very similar. I'll try the approach that the
easyBackup page suggested, and see if it helps.

If Nextcloud works like OneDrive, then it could be caused by the problem

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.
