Ok, so I have restored a database over the network (16hrs) to standby. I am not sure which subsequent differential I want to apply, so I took the step of detaching the database, copying the files, and reattaching it.
Problem now is that it seems to be fully recovered - I can't attach any more backups...
So, I am assuming it was the attach that recovered it - I may be wrong - is there any way to tell? Another 16hours of network restore would be miserable...
Ta.
