Figure 10 – Backup time comparison
7.2 Database recovery – key observations
Complete Recovery
Time to complete database recovery for the three different methods is shown in Figure 11.
• As expected, the time to complete recovery from an RMAN full backup when comparing
regular RMAN to EqualLogic snapshot based RMAN was similar.
• Also as expected, the time to complete recovery from incremental RMAN backup was
significantly lower than from full backup.
