Illustration strms057.gif shows that the `inst1.net` database and the `inst2.net` database do not share a computer file system. The `inst1.net` database runs a report at set intervals that adds the report files to the `sales_reports` directory object. This directory object corresponds to a directory on the `inst1.net` database's computer file system. Each time a new report is run, the report files in this directory are copied to a different directory on the `inst2.net` database's computer file system.

The illustration shows a file group repository in the `inst2.net` database with two versions of this tablespace set: `sales_reports_v1` and `sales_reports_v2`. Other versions can also be added to the file group repository. The illustration also shows the directory objects on the `inst2.net` database's computer file system that store the files in these file groups. The `sales_reports1` directory object stores the files for version `sales_reports_v1`, and the `sales_reports2` directory object stores the files for version `sales_reports_v2`.
