Return Value
An System.IAsyncResult interface that represents the asynchronous operation started by calling this method.
BeginBackup 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 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.
