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 Managing logfiles.• 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. Click Repository Management> Snapshot Management > Snapshots.
3. In the edit area, in the Snapshots tab, click New 
.
.A creation wizard appears.
4. Select the criterion to be used to find the state of the repository to be captured:
• design tasks
• Dispatches
5. Click Next.
6. In the Local Name field, enter the repository snapshot name.
7. Select the task/dispatch
8. Click Finish.
You can automate snapshot creation through the scheduler. For more information see Managing the Scheduling (Scheduler).
