==== Environment Details
OS : Oracle Linux 6.7
DB version: 11.2.0.4
We are currently at the design stage of critical DB . These DBs will be in RAC.We want to backup to FRA first and then backup FRA to tape.
We don't want point-in-time recovery. ie. In case of a disaster, We just want to restore,recover the DB to the most recent version (before the disaster occured) ASAP.
At, this point , we are not planning DR (Dataguard) for this DB . But, we will configure DR within 1 year after Go-Live.
The DB size will be around 7TB with 500GB of archivelog generation every day.
How much space should we allocate for FRA and ideally what should our backup strategy be ?
