SMO Restore Failed/Cannot Open Backup Device Error

I got an error while I'm trying to restore a SQL Server 2008 R2 database:

Restore failed for Server 'KIMO-PC'.

Code used:

    Server myServer = new Server("KIMO-PC");
    Database myDatabase = new Database(myServer, "POS");
    Restore restoreDB = new Restore();
    restoreDB.Database = myDatabase.Name;
    restoreDB.Action = RestoreActionType.Database;
    restoreDB.Devices.AddDevice(FileName, DeviceType.File);

    restoreDB.ReplaceDatabase = false;

    restoreDB.NoRecovery = true;

    restoreDB.PercentComplete += CompletionStatusInPercent;
    restoreDB.Complete += Restore_Completed;

    restoreDB.SqlRestore(myServer);

and here is the exception details

Solution

  • Take a look at the stack trace inner exception:

    Cannot open backup device 'C:\Users\kimo\Desktop\POS.bak'. Operating system error 5

    Most likely, the SQL Server does not have rights to view files in kimo\Desktop. Move the backup to a different folder like c:\temp and try it again.
