The directory path for Replication Agent System Database (RASD) backup files.
When you create a Replication Agent instance, an RASD backup directory is created automatically as part of the instance directory structure. The default value of the rasd_backup_dir parameter points to that directory.
If you specify any valid path as the value of the rasd_backup_dir parameter, Replication Agent places its RASD backup files in that directory during RASD backup operations, and it looks in that directory for the RASD backup files during restore operations.
