Database Reference
In-Depth Information
Finally, we talked about actually backing up your database with RMAN. We talked
about the various kinds of backups available to you, from complete database backups to
incremental backups. We covered backing up tablespaces and data files and backing up
archived redo logs. We even talked about backing up the backups themselves, as if we were
not already talking to you in circles enough.
In the following chapters, we will be covering the RMAN recovery catalog, recovering
your database with RMAN, reporting from RMAN, and finally, advanced RMAN recovery
topics. So there is plenty of fun yet to go. Hang tight—it's going to be a fun ride!
