I try to use usn-policy = Auto to backup from NTFS-Volumes. Now i get an error “[Information-Duplicati.Library.Main.Operation.BackupHandler-FailedToUseChangeJournal]: Failed to use change journal for volume Zugriff verweigert” (German Version; “Zugriff verweigert” means “Access denied”).
I think that this is not a Problem of duplicati but a problem with rights. Maybe somebody knows witch right to set.
I run Duplicati - 2.0.4.8_canary_2018-12-13. I try to use USN since 2.0.4.5. It did not work at all till now. The problem has been from the first time of using USN. I don’t think that it is a matter of duplicati. I think duplicati has not enough / the correct rights to use USN.
Maybe somobody can tell more who is using USN and where it works.
thanks
General web search for non-Duplicati USN change journal use (such as fsutil usn readJournal) says it needs Administrator privileges, and if Duplicati is subject to the same controls, this means either install as a Windows service, or run Duplicati as a user in the Administrators group. If you run with the automatic start-at-logon tray icon option, the shortcut lives in C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp and you would Right-click → Shortcut → Advanced → Run as Administrator. Because it’s a shared setting, any users who are not Administrators might get asked at login to enter a password for an Administrator user.
Not ideal, but perhaps you or someone else can figure out if this is necessary, and if there’s a better setup…
If you take the Windows service route, which requires manual work, life for this (and snapshot-policy) is easy:
