Hi

Windows Server 2022 VMs with SQL Server 2022 installed are having the backup job via Veaam B&R Version 12 fail with the following error:

Unable to release guest. Error: Failed to call RPC function 'Vss.Unfreeze': Error code: 0x80004005. Failed to invoke func [Unfreeze]: Unspecified error. Unfreeze error: [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: [{91ba41ea-7fa0-4b18-86ef-d62932435085}]. Writer's state: [VSS_WS_FAILED_AT_PREPARE_SNAPSHOT]. Error code: [0x800423f0].].

Veeam support is going around in circles, only know the basics with SQL Server app and haven't had this issue before with other VMs that have SQL installed.

Assistance would be appreciated.

Thanks
