[valeris]

Hello,

 

Could someone explain how to fix the following error:

 

- 10/1/2008 10:53:54 AM: Copying DB_TABLE on DB_SERVER

Backup type: Full

Trouble reading files, error -3840 (The operation terminated abnormally.)

10/1/2008 10:56:18 AM: Execution incomplete

Remaining: 1 files, 42.9 GB

Completed: 0 files, zero KB

Performance: 0.0 MB/minute

Duration: 00:02:24 (00:00:16 idle/loading/preparing)

This error is coming directly from the SQL Server. What do your SQL logs and Windows event logs show for this backup attempt?

 

Does it happen with every backup attempt? Are you able to backup the database with the built in SQL backup tool? Does it fail too?

I have found following MSSQL errors in Application part of system eventlog:

 

EventID : 17055

3041 :

BACKUP failed to complete the command BACKUP DATABASE [TMESCOPE] TO VIRTUAL_DEVICE='dantz_retrospect_vd_TableName' WITH INIT

 

18210 :

BackupVirtualDeviceSet::Initialize: Open failure on backup device 'dantz_retrospect_vd_TableName'. Operating system error 0x80070002(The system cannot find the file specified.).

 

MSSQL has errors with the same description as above.

 

I gave these errors for all tables at this server for each backup attrmpt.

The error reported by Microsoft is the 0x80070002 error. You should be able to google that error.

 

Retrospect sends a backup command to SQL. SQL copies the backup to a virtual device and Retrospect reads the virtual device.

 

It sounds like your server is having a VDI failure.

 

Google 0x80070002 and the event ID's reported my Microsoft.
