Re: diff between incremental and archive backups

This may sound dumb, but backups aren't really for recovery these days. Business continuity - 24x7 and all that - means backups are generally useless. The are for historic regulatory storage. They are for unmitigated multi-site corruption. I haven't restored a backup to get a system back up and running - with one weird, unusual but appropriate-for-the-business exception where we didn't do regular backups - for well over a decade. Maybe even 20 years. The last critical DB restore I recall was in 1997 for a large German bank.

Now, you don't restore, you failover. Cluster, data guard, golden gate (a bit data-lossy but fine for most).

The thought of having to restore tens of TB from compressed slow Sata disk. *Shudder*

Many use BCT to make incrementals more efficient. Many also backup DataGuard physical standbys, instead of the primaries, although there are some RMAN bugs involved between 11.1.0.6 and 11.2.0.3.
