Creating Repository Snapshots
To be able to use repository snapshots, you must:
• have the repository log activated (default case).
For more details on repository log activation, see Repository log.• set up a procedure for taking account of repository snapshots before deletion of historical data.
A repository snapshot identifies an archived state of the repository. When an archived state of the repository has been deleted, it is no longer possible to create a repository snapshot corresponding to 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, RDBMS Administration > Shrink unused repository historical data).
For more details, see "Repository - RDBMS Installation Guide", "HOPEX Historical Data Cleanup". To create a repository snapshot from the HOPEX Administration desktop:
1. Connect to the HOPEX Administration desktop.
2. Select Repository > Repository Snapshots.
3. In the edit area, click New 
.
.A creation wizard appears.
4. (Optional) In the Name field, modify the default repository snapshot name.
5. Select the criterion to be used to find the state of the repository to be captured:
• design tasks
• Dispatches
6. Click Next.
7. Select the task/dispatch
8. Click OK.
You can automate snapshot creation through the scheduler. For more information see Scheduling (Scheduler).
