Hi,
DB=10.2.0.4 OS=RHL (RAC with 2 nodes db01,db02). Following are the types of automated RMAN backups taken on db01.
- OCR
- Voting Disk
- Talespaces Snapshot
- Archivelog (every hour)
- Backup Incremental level 0 (SUNDAY)
-- backup incrementa level 1 (Mon-SAT)
- Autobackup of Control file and SPFILE (CONTROLFILE AUTOBACKUP ON)
Two main questions please. First, are these backups/backup types are enough FOR FULL RESTORE when talking about RMAN backup on RAC environment with 2 nodes? If not please suggest what else I need to backup?
Secondly, backup home location is /rman which I can see on db01 ONLY. This /rman directory I cannot see on db02. My question is that In case of db02 failure can I restore from this /rman directory? or do I need to automate backup schedules also on db02 separately?
