Creating VSS snapshot Error


Buongiorno, sto valutando veeam backup comunity edition, ho installato in una macchina virtuale il tutto e in un altra con win server 2019 sto tentando di eseguire un backup, ma quando parte, poco dopo, va subito in errore dicendomi:

 

26/08/2024 13:02:08 :: Creating VSS snapshot Error: Failed to create snapshot: Backup job failed. Cannot create a shadow copy of the volumes containing writer's data. A VSS critical writer has failed. Writer name: [SqlServerWriter]. Class ID: [{a65faa63-5ea8-4ebc-9dbd-a0c4db26912a}]. Instance ID: [{96f8634f-b88b-4cf9-bacf-cf3da979d9f9}]. Writer's state: [VSS_WS_FAILED_AT_PREPARE_SNAPSHOT]. Error code: [0x800423f4]. Failed to create snapshot: Backup job failed. Cannot create a shadow copy of the volumes containing writer's data.

Writer's state: [VSS_WS_FAILED_AT_PREPARE_SNAPSHOT]. Error code: [0x800423f4].

 

Come mai? Fatemi sapere per favore, che se funziona il tutto probabilmente il cliente mi acquisterà la licenza.. Grazie

ciao, questo è un errore a livello di sistema operativo windows: non riesce a fare lo snapshot VSS. L’utenza che hai inserito ha i permessi necessari sul DB? (https://www.blackmanticore.com/cd83ed1812094e7e423a88efe3b78015) puoi anche dare un’occhiata a questo post https://forums.veeam.com/veeam-agent-for-windows-f33/a-vss-critical-writer-has-failed-sqlserverwriter-t35512.html

Puoi comunque fare, in attesa di trovare una soluzione per l’errore sul VSS Writer, un backup “crash consistent”, come spiegato qui

Ciao @futureoffice ,

per caso hai provato a fare un reboot della macchina di cui vuoi effettuare il backup?
