In 11.2, I have an incremental RMAN backup strategy with a level 0 done
on Sunday and level 1 done every other day of the week, with archive
logs running every 15 minutes. Retention is set to a "RECOVERY WINDOW
OF 1 DAYS".
Why are the archive logs older than 1 day not considered obsolete? My
understanding is that a complete (or recent PIT) recovery would be:
- Restore level 0
- Recover all level 1 backups
- Recover archive logs since last level 1
So, why are the older archive logs not obsolete? I see keeping at most
2 days, but there are currently 5+ days in the FRA.
I'm not using a catalog if that matters (and the controlfile autobackup
Thoughts? With an archive running, I realize that my FRA freespace is
way lower than I'd like...
