How to saveas in-memory office document without renaming

[Rino Farina]

Hello all,

I am working specifically within Visio Automation. Does anyone know if there
is a way to save the current working instance of a Visio document to the
filesystem, ie. perform a backup of the document to a backup directory,
without changing the document path, name, and fullname properties?
Unfortunately, these properties are readonly.

The idea is to provide a way to take snapshots of a document during key
points, like a timer event, so that any one of those snapshots can be opened
later.

Thanks in advance
