Dateisicherung: "Backup failed"

Guten Morgen,
ich bekomme auf dem Server bei Dateisicherung im Protokoll diese Meldung:|

24.09.20 08:52 DEBUG HT: Copying file: “/share/urbackup/srv/200924-0847/D/ServerFolders/Firma/sfirm_v4/Basis/tmp/ntfycntr/data/data_0”

Am 31.3.2020 war die letzte funktionierende Dateisicherung.
Die Image Sicherung funktioniert.

Wie könnte ich hier zur Lösung des Problems herangehen?

Danke für Eure Antworten

Look into Windows event viewer for SQL Server messages. Or disable Windows component backup (change from default=1 to default=0 in the advanced settings for example).

Danke hat geklappt!
