EXAM TIP When faced with a system failure where you lose your SSRS instance and/or
database, you will:
* first need to reinstall SSRS.
* After the installation is complete, you can optionally restore the latest backup of your report
server catalog database (if it was also lost).
* After the service and catalog databases are in place,
* your final step is to restore the encryption key onto the newly installed instance of SSRS.
This will enable the report server to be able to decrypt the catalog security, reports, and data
sources.
