ExternalStorage move sdata out of the database as soon as it is
successfully stored externally.  It is not kept in the database, and
the database does not need to be vacuumed.  The initial storage in the
database is needed to ensure durability of the data, in case of file
permission failure, or network failure (in the case of the cloud
storage options).  It is not a backup solution.

It also does de-duplicate files, so I'm unclear what you mean by that
