No. You didn't get my question right.

I asked about copying using windows valume shadow copies.
These are frozen, they cannot be changed by the database server.
(The database server can modify it, but that's another instance.)

I always wondered, why the concept of volume shadow copies are so difficult
to understand for database people.
Windows volume shadow copies are basically snapshots of a filesystem with
transaction support. Once opened a volume shadow transaction to a folder,
the content YOU SEE cannot change anymore. As it is with transactions in a
database ...

Hence, the database file the copy process sees is immutable.

All this is obvious. But it doesn't apply to the scenario in question.
