Restoring a deleted module from a RM project

Unfortunately you can't easily restore deleted artefacts, even though an RM project deletion is a 'soft' delete because they remain in any baselines you've taken.

 - you can absolutely restore the RM database from your backup because it's self contained. Be aware that any cross application links that you've made to project areas in other applications since the backup will be affected. You'll also need to completely reindex your data warehouse sources as they will have data since the backup

- recovering the deleted module would, in theory be possible, but would require some serious DB work as multiple tables and views would be affected. Very risky proposition

- if you have point in time in your server then that would also work but you'd be rolling everything back to that time. You'd lose any changes you made since. I have had to do this before for a client - we set up a full backup environment that I flicked between and I ran queries to figure out everything created or modified since the point in time, and manually changed the artefacts. Took about a day in total, but this will grow as the point in time gets older

 - you can't recover the baseline directly. This would require DB manipulation once again

As you have backups, and baselines, that contain the module and its artefacts, I would raise a ticket with IBM Support to see if they can assist you with the necessary DB manipulation.

Once you've got the baseline you can export a view to (say) spreadsheet and import into your stream; you won't get changes to incoming links but depending on your view you can get outgoing links.
