Hello,
I have a windows 2008 R2 domain controller on a HYPER-V virtual machine that is failing all backups.
The error is always the same:
Descrizione: Errore EC8F17B7: Impossibile creare i punti di ripristino per il processo: Backup DC2.
Errore E7C3000F: Il dispositivo \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy27 non riesce a leggere i settori 12.304 a partire da LBA 2.502.072.
Errore EBAB03F1: Si è verificato il seguente errore del sistema operativo durante l'esecuzione dell'operazione richiesta: 'Impossibile eseguire la richiesta a causa di un errore di dispositivo I/O.'
Dettagli: 0xE7C3000F
where the "27" after shadowcopy is a number that starts from 1 and increases after every failed attempt, and resents after rebooting.
Same days ago I was able to make a backup, after changing the backup setting by adding the option "make a full VSS backup". After changing that option I was able to make a backup, then a few days after the error started to appear again.
I have already run chkdks /f/r and no error was found.
