archivelogs and backups without FRA. Am I correct? Thanks, Roger Xu
Deletes based on retention policy delete everything older than the
policy states with total prejudice. With the FRA, nothing is thrown
away unless space is needed for new backups or archivelogs. So there
is a good chance that in any given recovery scenario, you will have a
longer history of backups in a space-based pool like the FRA, than
with a system of deletion based on date. There is a good chance that a
time-based retention policy will delete files even when there is
plenty of room to keep them. Why not keep more backups around?
