Hi I am trying to Backup my SQL server using the VDI
(Virtual Device Interface) APIs I have the capability of
creating and mounting snapshot.
I have already looked at the sample called "snapshot".

As far as It is one DB it is OK, everything goes smoothly.
But when I have more then one database on the same
partition,I need to ensure all the databases are at "Hot
backup state" and flush all the metadata of all the DB in
order to ensure a consistency state.
I have tried almost everything but it seems that nothing
works,
any Idea?
I have tried to create one Virtual device set, and open a
virtual device per DB. The Backup statement is per
database, and when I am trying to run more then one
statement I failed to open the devices. any solution will
be appreciated.
Thanks
