💾 RMAN Control File Backup: Your Database's Safety Net! #OracleDBA

To backup the control file in Oracle, use:
sql:
RMAN) BACKUP CURRENT CONTROLFILE;

**Why this matters:**
✔️ Control file = Database's GPS (stores critical metadata)
✔️ Auto-included in full backups (`BACKUP DATABASE`)
✔️ Manual backups recommended before schema changes

**Pro Tip:** Add to archive for disaster recovery:
sql:
RMAN) BACKUP CURRENT CONTROLFILE FORMAT '/backups/ctl_%U.bkp';

⚠️ **Warning:** Losing control file = Database crash!
