Yes, I see that there are some VSS events intercepted in event viewer when I run a snapshot. But in my particulr case I have an Oracle database used for Business Intelligence that for performance reasons is not in archive log mode, so it can't interact with VSS layer. Due to its nature I can shutdown this database during the evening and then reopen it before the ETL processing happens during the night. So in that time frame I would like to have a pre-snapshot operation of shutdown db and post-snapshot operation of start db. And then I clone the snapshot and export it in case I have to restore the "blob" as a consistent whole It is for this reason that I'm trying to verify if the freeze-hook is usable also in WIndows environments (based on some threads I find it should be...)
