We have a somewhat large database server (about 8TB across 5 databases) with very high activity (125 log switches per hour per database). We are looking to reduce our recovery time and the large number of archive logs that would need to be applied takes too much time. What is the best solution for quickly recovering large Oracle databases with high activity (CDP solutions? Disk array snapshots? Oracle Flashback? Oracle Data Gard?) Are there other types of solutions?
