I’m just starting migrating from old Duplicati to Version 2.
Running Windows 10 20H2 and tried running Duplicati with admin privileges, as service and through Task Scheduler with highest privileges. Nothing changes the following problem.
I have turned smnapshot-policy to “on” but I always get the following message as a warning:
[Warning-Duplicati.Library.Main.Operation.BackupHandler-SnapshotFailed]: Failed to create a snapshot: The provider returned an unexpected error code.
I then tested it with some restricted folders on C: and get many warnings like thise:
[Warning-Duplicati.Library.Main.Operation.Backup.MetadataGenerator.Metadata-MetadataProcessFailed]: Failed to process metadata for “C:\ProgramData\Packages\Microsoft.XboxGamingOverlay_8wekyb3d8bbwe\S-1-5-21-100176517-2775799961-2918127677-1002\SystemAppData\Helium\Cache\8de27c5cbf34241_COM15.dat”, storing empty metadata
I found some threads also having problems with snapshot policies / VSS but so far nothing helped.
Hope you guys have ideas.
