Point in time recovery allows you to restore you system to a single point in time. Backups, depending on how they're performed, give you multiple points in time from which to recover. > What I want is to have a identical backup drive at > every moment in time.

Keep in mind that dump remembers, via dump levels, what's been backed up so it will do incremental backups. > Geom looks cool, I will start reading the docs and > look into them.
