public IAsyncResult BeginBackup( 
   string fileName,
   AsyncCallback callback,
   object stateObject
)

Parameters

fileName

The name of the file to write the script to.

callback

The delegate to call when the asynchronous invoke is complete. If callback is a null reference (Nothing in Visual Basic), the delegate is not called.

stateObject

State information that is passed on to the delegate.

Return Value

BeginBackup(String,AsyncCallback,Object) method enables you to perform a backup operation without having current thread blocked. In other words, your program can continue execution while the backup runs in background so you do not have to wait for it.

To start the backup operation, you have to call BeginBackup(String,AsyncCallback,Object) method, which in turn invokes appropriate actions in another thread. Return value of this method must be assigned to an System.IAsyncResult object. After executing this method, the program flow continues.

When you are ready to finish the backup operation, call EndBackup. If at the moment you call this function the backup has not yet been finished, application stops and waits till the function returns.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
