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

Описание: 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!
