Possible to recover master server after power outtage?

I'm still new to Netbackup when the server crashed. I have access to all the files on the old c drive and the basic disk where backups were going to. Without building everything from scratch, can I grab any configuration or database from the old c drive or one of my img to help my rebuild of the server? I didnt quite understand DR file in my google research. Is that something on the c drive or included in your backups? Or do you have to set it in your backup jobs to backup the DR? And Iif you didnt expressly create a catalog backup policy, am I SOL? TIA
