About DB Replication and Backup
Hi Experts,
A customer database that is Oracle 12.2.0.1 running on ARCHIVELOG mode. They have below backup and DR strategies applied.
1. An application that replicates the hard disk drives of OS, database software, datafiles, redo log files, archived redo log files, control files and spfile to a DR server real time. DR server will auto boot if the production server is down for whatever reason. DR drills proved it works.
2. RMAN is also running every night that will perform full database backup (BACKUP DATABASE), archivelog backup (BACKUP ARCHIVELOG ALL) and delete obsolete archivelog that is SYSDATE-7. Backup is then moved to tape drive and stored off-site.
