Managing Repository Snapshots
To use repository snapshots, you must:
• check that the repository log is enabled (default value).
For more details on repository log activation, see Repository log and Consulter et modifier les propriétés du référentiel.• set up a procedure for taking account of repository snapshots before deletion of historical data.
A repository snapshot captures a historical state of the repository. When a historical state of the repository has been deleted, it is no longer possible to create a repository snapshot that captures this state.
It is therefore important to take management of repository snapshots into account when deleting historical data (in Administration.exe, via the repository pop-up menu: Administration RDBMS > Shrink unused repository historical data).
For more details, see "Repository - RDBMS Installation Guide", "HOPEX Historical Data Cleanup". Creating a Repository Snapshot
