In the SQL Server backup world, there are lots of 3rd party applications available that plugs into SQL to back up the databases. The likes of CommVault, IBM Tivoli, Symantec BackupExec, Quest Litespeed, Redgate SQL Backup all uses the sqlvdi.dll to communicate to SQL Server. Lately I have seen backups failing and the following errors are usually logged:
1. [Error Code: [30:322] Description: Failed to initialize for VDI Backup. CCvSQLVDIBase. Initialize() failed.
Check if SQLVDI.DLL is registered]
2. [Error Code: [30:325] Description: Error encountered during backup. Error: [Cannot open backup device '99bd6255-9610-4cfd-b8ff-83fc674cbd47'. Operating system error 0x80070005(error not found). BACKUP DATABASE is terminating abnormally. An exception occurred while executing a Transact-SQL statement or batch.]]
3. [Event ID: 1, SQLVDI: Loc=TriggerAbort. Desc=invoked. ErrorCode=(0). Process=2716. Thread=2148. Server. Instance=MSSQLSERVER. VD=Global\331e46ea-551a-4bb1-b628-5abbeb9fa10f_SQLVDIMemoryName_0.]
This tool is not intended to fix this errors but rather help determine whether the SQLVDI.DLL is registered and functioning correctly and where you need to concentrate your troubleshooting efforts in the events of SQL backup/restore operations failing due to VDI errors.
